PREFACE.

s conjectured last year, considerable further changes have been produced in this edition.

When, some five years ago, work on this annual was first commenced, the military aviator was an idle dream. Fighting men in dirigibles were a bare possibility; but nothing more than that. Every amateur building an aeroplane (or even merely intending to build one) in his back garden was a possible "conqueror of the air." The aeroplane was going to oust the motor car as a sporting vehicle—everyone was quite certain about that! Beyond that, nothing!

To-day everything is completely changed and except as a war machine the aeroplane is of little interest or use to anyone. A few civilian aviators are still flying, but in practically every case they are doing so in connection with the business aspect of the question. There is no "sport of aviation" such as the prophets foretold a few years ago.

An increasing number of people obtain their pilot certificates and lists of these are still given, although the title of "aviator" is in the bulk of cases somewhat of a courtesy one, since so few keep on flying once they have secured their brevets.

It is as a war machine that the aeroplane has come into its own. The Italian aeroplanes over and over again proved their utility in Tripoli. Although in the Balkan War aircraft were less in evidence than many expected, this may be attributed to the peculiar circumstances of the campaign and also to the scarcity of available machines.

Every country is now engaged in forming its aerial fleets. How far the naval and military branches will coalesce, or how far they will differentiate remains to be seen. The probabilities, at present, all point in the latter direction, and that just as an army is made up of cavalry, infantry, artillery, etc., and a navy of battleships, cruisers, torpedo craft and submarines, so the sky fleets seem destined to consist of groups of different types of machines, each type designed for some special purpose.

The increased war utility of aircraft has necessitated an extension of the pages devoted to organisation of military aviation, etc. The details given are by no means as full as I could wish; but all organisations are being so continually changed owing to increased experience that satisfactory data are not very easy to come by.

During the past twelve months or so we have learned at least one or two important things. The mere fact of the possession of aeroplanes by a nation is a military factor of comparatively little importance. A nation possessing next to no aeroplanes can easily acquire a few hundreds in case of emergency if she has the people to build them. The real problem is two-fold. First, of course, is the possession of trained and efficient aviators to fly the machines. Naval and military officers who have merely secured their brevets at a flying school are of no immediate value; civilians of the same kind are of still less utility.

Second to this is the productive capacity of any country; which may roughly be gauged from the number and importance of its firms engaged in construction.

These points cannot too strongly be enforced. The air strength of any nation in case of war resides in its efficient flying men and in its own productive capacity. The next war will see aircraft quite as much "contraband" as warships, and the nation which relies upon aerial imports will be foredoomed at once. One month is probably the utmost effective life of an aeroplane on hard active service and it may well be a good deal less. And firms capable of building efficient machines cannot be improvised.

A remarkable feature of the last twelve months has been the recrudescence of the dirigible, which is now in far greater esteem than it was a year ago, or for that matter, ever before. In the past there is no doubt that progress was hampered by arguments between the advocates of "heavier than air" and "lighter than air," and a curious notion that the one could only exist at the expense of the other.

Such ideas are now dead, and it is recognised that for war purposes both have their uses and that both are interdependent. It is not quite yet realised how intense this interdependence is likely to be.

Briefly the present situation may be summed up as follows: the dirigible has enormous potentialities for attack on fortified bases and the like, but its powers of defence, guns or no guns, are very slight. A single aeroplane should be able to disable or destroy without very great difficulty the finest dirigible yet built (supposing it able to find the airship in the vastness of the air). The damage that a single aeroplane can do to land defences or ships is, however, entirely trivial—at any rate at present.

Hence the aerial war unit already formed in Germany, and likely to be in existence everywhere else ere another year or so has passed. This unit is a dirigible of great offensive powers, associated with a number of aeroplanes presumably intended to defend it and ward off and defeat attack by hostile aeroplanes.

This is merely the crude beginning, it seems reasonably safe to prophecy that in the early future the aerial war-unit will be made up somewhat as follows:—

(a) An offensive dirigible, carrying the maximum of bombs, etc.

(b) One or two dirigibles carrying oil and petrol for the aeroplanes—possibly capable of dealing with all minor repairs and of carrying a certain number of aeroplanes on board.

(c) A number of war aeroplanes specially designed for fighting other aeroplanes and attacking hostile dirigibles as chances may occur.

(d) A few very swift one man aeroplanes which will be the eyes of the unit.

This seems an early certainty. After all it merely reproduces for the air what centuries of experience have shewn to be essential for fleets and armies.

The matter is a fascinating subject for speculation; but in connection with a work that exists merely to deal with things as they are at present, is perhaps, better not now pursued further. One point, however, may perhaps be mentioned, and that is that victory or defeat in aerial warfare seems likely to depend upon which side can first destroy the other's bases. A base-less dirigible will not live long. This is likely to lead to very great attention being paid at an early date to anti-aircraft guns and other devices for the defence of aerial bases.

Reverting to the arrangement of the present edition, a few words may be said about some of the changes. As stated last year the clumsy old system of grouping monoplanes, biplanes, etc., separately has been abolished. So many firms specialise in both that any such grouping could only lead to confusion.

A tabular system has been generally adopted for most new matter. This will be found far more convenient for reference, and of course, saves a great deal of space.

The effective age of aeroplanes is somewhat of a vexed question, for while one year probably represents the really effective war utility endurance, even in peace time, school life is more or less indefinite and so is ordinary private life. Consequently—although "dead machines" are excluded it has not been possible to draw an exactly uniform age limit line beyond that. Speaking generally modern machines represent as a rule detail improvements rather than the complete changes of the past. For example, the gap between 1911 and 1913, is far less than the gap between 1909 and 1911. This fact is beginning to make itself felt in war machines.

In Part B an attempt has been made to collect illustrations of aeroplanes of the past which for one reason or another possess an historical interest. This section is remarkable for two totally different things (1) the early anticipations of some modern practice, and (2) the past prevalence of certain other ideas which are now totally extinct.

Part C deals with aero-engines. It is mainly remarkable—in comparison with past issues—for the large number of engines which have ceased to exist. It is probably still too ample; as a year hence quite half the makers still recorded are likely to disappear. The mere ability to construct motor car engines is no longer of value. The aeroplane engine designer needs to be a specialist. The absolutely ideal aero-engine no doubt yet remains to be produced; but meanwhile the tendency of users to concentrate upon fewer makes is increasingly evident, despite the fact that the best engine for one particular type of machine is not necessarily the best for some other type.

In conclusion I tender my most grateful thanks to all those who have so kindly collaborated with or for me in the various sections. The book is still some way from being near my ideal, but I have every hope that this edition will be generally considered a very considerable improvement upon previous issues.

AUSTRO-HUNGARIAN AEROPLANES.

Military Aviation: General.

In June, 1912, a central aeronautical committee was created, under the presidency of Prince Fürstenberg, to deal with the creation of a national aerial fleet. One of the objects is the perfection of the Austrian machines and factories.

About the same date, Pola was selected as a naval aviation school, and two Paulhan-Curtiss hydro-avions purchased.

In August the record making Lohner was purchased for the Army.

During September Captain Odolek tested before the military authorities a parachute of his invention; and a number were ordered.

In October very strict regulations were issued as to aircraft flying over prohibited areas, a rule that any offenders would be shot at was subsequently modified.

In November a Donnet-Lerêque was purchased for the Navy and another ordered at the Whitehead Works, Fiume.

Army Section.

At the end of 1911 the Army possessed 4 monoplanes and one biplane (a Lohner), now available for school work.

During 1912 there were acquired:—

20 monoplanes.—1 Bleriot, 2 Nieuport, 15 Etrich-Taube, 1 Etrich limousine, 1 Deperdussin.

6 biplanes.—4 Lohner-Daimler, 1 Mars, 1 Klobucar, (of the above the 2 Nieuports, 1 Etrich limousine and the 4 Lohners were the only ones built in Austria).

Naval Section.

4 hydro-avions were acquired during 1912; 2 Donnet-Levêque and 2 Paulhan-Curtiss.

BELGIAN AEROPLANES.

Military Aeroplanes.

At the end of 1912 the military air force consisted of three 50 h.p. Gnome H. Farman 1911 military, used for instructional purposes, and twenty-four 70 h.p. Gnome H. Farmans (model 1912 military), for war work:

The military school is at Brasschaet, near Antwerp. Major Campion in command.

The course is as follows:

1. Theoretical course.—Lectures on meteorology, structure of aeroplanes, aviation motors, etc.

2. Practical.—This, in addition to flight, consists of dismounting and replacing parts of aeroplanes and aerial motors, all general repairs, erecting hangars and aerial photography.

The school possesses nine hangars, of which three are Bessonneau type, three wooden, and three metal.

For 1913 the sum of £20,000 is to be expended for purchase of aeroplanes and the establishment of aerial squadrons at Antwerp, Liege, and Brasschaet.

These are organised into six squadrons of four units each. The full complement of each squadron is eight aviators, fifteen to 20 mechanics, etc., and six citizen soldiers.

The question of hydro-avions for the Congo is under consideration.

BEHUEGHE

(Bron), in Herseun. Built in 1912. A monoplane that flew very well at camp of Casteau Aerodrome during May—October. Motor.—25. h.p. type Morane. New designs in wing construction, landing chassis, etc.

A. BRACKE

(formerly Bracke, Missyon & Co.), Casteau, Mons. In 1910, constructed the first aeroplane built by a Belgium firm—a monoplane with planes at 120. This machine has not been duplicated: but the firm have since built machines to private specifications. The only firm which has in Belgium the speciality of aeronautical patents.

DE BROUCKERE,

23 rue Joardens, Brussels. Biplane. H. Farman. type. Built in 1911, modified in 1912.

DE LA HAULT

Adhémar de la Hault, 214 rue Royale, Brussels. In 1906, built a flapper of novel design. This was followed in 1910, by a machine on monoplane lines with one fixed plane and two flapping wings. This failed to fly, and in August, 1911, was altered into a biplane. It did not succeed, however. M. Hault is still pursuing the ornithopter question.

HAREL I. Biplane.

Length.—49¼ feet (15 m.) Surface.—344½ sq. feet (32 m².) Weight.—771 lbs. (350 kgs.), flying order. Warping wings. Monoplane tail. Motor.—50 h.p. Gnome, mounted just under and forward of the upper wing. Tractor.—1 Chauviere. Elevator placed 1 in front and 1 in rear, H. Farman style. Rudders, 2 in rear. Completed May, 1911. For further details see Conquete de l'Air, July 1st, 1911. Property of M. Van der Stegen.

WILLIAMS. Biplane.

Motor.—70 h.p. E.N.V. Generally of headless Voisin type on a Farman body. Completed 1911. Has flown fairly well.

Remarks.—Reconstructed in the winter of 1909. There are two noteworthy innovations in connection with the ballonet. (1) The ballonet can be warmed by the motor. (2) In case of real emergency air can be pumped direct into the gas bag. Experiments of the utmost importance to all airships are in progress with a view to ridding the gas of this air cheaply and quickly.

LA BELGIQUE III. Military.

Presented 1910 to the Belgian Government by H.M. the King of the Belgians. 4,500 m³. Practically same as II, but has 3 propellers. Motors.—Two 100 h.p. Germain.

VILLE DE BRUXELLES.

(Formerly known as LA FLANDRE.)

(Astra type.)

Maximum length, 256 feet (78 m.) maximum diameter, 41 feet (12.4 m.) volume, 212,000 c. feet (6,000 m³.)

Total lift.—15,763 lbs. (7,150 kgs.) Useful lift, ? lbs. ( ? kgs.)

Gas bags.—Continental rubbered fabric, yellow. Ballonet, 16,146 c. feet (1,500 m³.)

Motors.—2 Pipe motors of 100 h.p. each, placed in line with each other in the fore and aft line, and with clutches and the necessary gearing in between them.

Speed.—35 m.p.h.

Propellers.—3, namely: one at the fore end, driven by the two motors when coupled together, and two placed above and on either side of the centre of the car, for use when only one motor is running. Chauvière propellers.

Steering.—Vertical steering by means of a large double aeroplane fixed above the car, about a third from the front. Horizontal steering by means of a double vertical rudder above the rear end of the car. Stability is secured by the usual Astra pear shaped stabilising gas bags, with fins of rubbered cloth spread between the inner edges of these shapes.

Remarks.—The distinctive feature of this ship is the arrangement of the propellers. Both motors can be coupled either on to the front propeller or on to the two rear propellers, or on to all three together, but they are actually intended only to drive the front one. On stopping either motor the other is connected to the two rear propellers, which are designed for a slower speed of translation than the front one, with the result that the running motor does not find itself overloaded as it would if the same propeller had to serve both for one and for two motors.

Army Wing Royal Flying Corps, Aeroplane Section.

The Army wing has its headquarters at S. Farnborough, its constitution being as follows:—

1st squadron (airships or kites) see Dirigible Section.
2nd squadron (aeroplanes) base at Montrose.
3rd squadron (aeroplanes) base at Salisbury Plain.
4th squadron (aeroplanes) base at S. Farnborough.
(Four more aeroplane squadrons pro.)

An aeroplane squadron nominally consists of 18 aeroplanes (9 in service, 9 remounts). At the end of March, 1913, the total number of aeroplanes, including those on order, school machines, etc., was about 110, of which about 50 (including some monoplanes not in use) were effective for war purposes or available at short notice.

The total of 110 was thus made up:—

22 monoplanes (= 2 Bleriot, 4 Bristol, 5 Deperdussin, 4 Howard-Flanders, 1 Martinsyde, 6 Nieuport).
86 biplanes (= 4 Avro, 22 B.E. type,[A] various makers), 2 Breguet, 2 Caudrons, 30 Farman (various types),
6 Short—and about 20 Avro or Farman or Short not delivered.

BRITISH AEROPLANES

A

AIRCRAFT FACTORY.

Royal Aircraft Factory, Farnborough, near Aldershot. For a long time this establishment had been engaged in dirigible construction and repairs. In 1911 it was decided to expand it in connection with the Royal Flying Corps. Its precise functions are somewhat uncertain. Its nominal main purpose is the repair, etc., of Service Aircraft. During 1912, however, it turned out several machines to a design of its own, known as the "B.E." This design was at one time regarded as confidential; but subsequently duplicates were built by private contractors, and the design illustrated below, published by the Advisory Committee for Aeronautics.

B.E. type. R.A.F. Uniform Aeroplane Scale

Length, 29½ feet (9 m.)

Span.—36¾ feet (11.20 m.)

Area.—374 sq. feet (34¾ m².)

Weight.—

Motor.—75 h.p. Renault and others.

Speed.—

AERO'S Ltd.

St. James' Street, Norwich Union Buildings, Piccadilly, London, S.W. Established 1912 for the sale of all parts and accessories; also for the sale of second hand aeroplanes and motors of all makes. Does not construct at present.

AIRCRAFT MANUFACTURING Co., Ltd.

47, Victoria Street, London, S.W. Works: Hendon, London, N.W. This company established in 1912, holds all the British rights for the H. & M. Farman types. It constructs in England all Farman types at its own works. (See Farman, French).

AVRO. Aeroplanes.

A. V. Roe & Co., Clifton Street, Miles Platting, Manchester; also Shoreham, Sussex. A. V. Roe designed his first machine, a biplane, in 1906. It was the first British machine to leave the ground. He then experimented with triplanes in Lea Marshes, where he managed to fly with only 9 h.p. in 1908-9. In August, 1910, built Roe III, and in September, Roe IV, also triplanes (see 1911 edition for full details). In 1911 he abandoned triplanes for the Avro biplane. School: Shoreham.

BLACKBURN Aeroplanes.

Blackburn Aeroplane Co., Balm Road, Leeds. Blackburn produced his first machine early in 1910 (see 1911 edition for details). In the latter part of that year he designed the machine which ultimately developed into the Blackburn military. In 1911 other types were produced, all being fitted with the patent Blackburn triple control. School at Filey Hucks has been the principal Blackburn flyer. The type has also been very successfully flown by naval officers. Capacity of works: about 24 a year.

Notes.—Petrol for 5 hours (higher endurances can be fitted). Specially designed for military work—all steel construction. All parts unwelded to admit of rapid displacement. Clear observation provided for.

Fuselage.—The fuselage is V shaped and constructed of weldless steel tubing in the form of a lattice girder. The main longitudinals are of round section; cross members, oval section. Connections are not welded but made with strong steel clips so that should any member become damaged a new one can be readily arranged. The front portion is covered with sheet metal giving additional strength and reducing the head resistance. Stream line form tapering towards the rear which is covered with fabric.

Chassis.—Two long skids connected up to fuselage by metal struts. Each skid borne by a pair of wheels, axle held down by elastic shock absorbers. On the axle of the wheels are fitted steel springs which take side thrust. Each pair of wheels held by radius rods forming a bogie.

Control.—Patent Blackburn triple, independent or simultaneous on hand wheel, but special foot control for rudder is fitted if desired.

In 1912, five machines were built, of which two were of the mil. model. Others, non-military models (see last edition.)

CODY.

Cody flying school, Farnborough. Cody commenced experiments with kites in very early days on behalf of the British Admiralty. Subsequently built the first British Army dirigible, and an experimental Army aeroplane. In 1909, his direct connection with the Army ceased. A Cody I was built in 1908. A Cody II was completed June 1910. The special features of both were: very strong construction, great size (II had area of 857 sq. feet), ailerons. Later types, except that warping is substituted for ailerons, do not differ very materially except in minor details. All wood construction.

DUNNE.

The Blair Atholl Aeroplane Syndicate, Ltd., 1, Queen Victoria Street, London, E.C. School: Eastchurch. In 1906 Lieut. Dunne was employed by the British Army authorities for secret aeroplane experiments. He had at that time patented a monoplane of < type. In 1907 Dunne I was tried on the Duke of Atholl's estate in Scotland, but failed to fly, being smashed on the starting apparatus. Dunne III, a glider, 1908, was experimented with successfully by Lieut. Gibbs. In the same year Dunne IV, a larger power driven edition made hops of 50 yards or so. Early in 1910 the War Office abandoned the experiments. Dunne II, a triplane of 1906 design, was, by consent of the War Office, assigned to Prof. Huntingdon, who made one or two short flights with it at Eastchurch in 1910. At the same time the above syndicate was formed, and Dunne V, built by Short Bros., was completed in June, 1910. In 1912-13 the Huntingdon, modified, was flying well.

GRAHAME-WHITE.

The Grahame-White Aviation Co., Ltd., 166 Piccadilly, London, W. Works and Flying Ground: Hendon. Founded by C. Grahame-White, the well-known aviator, who in 1909 commenced operations with a school at Pau. Later this was removed to England, and a general agency for the sale of aeroplanes, etc., established. This developed, and early in 1911 the firm was handling a special British agency for the U.S. Burgess type known as "The Baby." The Hendon Aerodrome was acquired, and a factory established, which has grown continually ever since. In April, 1912, a monoplane to special design was completed. By the close of the same year biplanes of advanced design were constructed. Capacity of the works, March, 1913, was equal to 150 machines a year if necessary.

HANDLEY-PAGE Monoplanes.

Handley Page, 72, Victoria Street, S.W. Works: 110, Cricklewood Lane, N.W. Flying ground: Hendon. Established at the end of 1908. In June, 1909, it was turned into a Limited Liability Co. Since then it has been busily employed in producing its own machines, also others to inventor's specifications. About the end of 1911 the firm bought up and sold all the machines of the Aeronautical Syndicate—Valkyrie and Viking types. It is doubtful whether any of these V type still exist—in any case it does not matter. Four were presented to the R. Flying Corps. Of these one was smashed up, the others, one army and two navy, were used to teach mechanics to take down and re-assemble engines, etc. Handley-Page also bought up the Radley-Moorhouse machines (Bleriot copies), and disposed of them.

The 1912-13 Handley-Page type is as follows—a development along regular lines of the original H.P. machine:—

Handley-Page V.

Length, 27½ feet (8.40 m.) span, 42½ feet (12.95 m.) area, 240 sq. feet. (22¼ m².)

Weight.—Total, 1300 lbs. (590 kgs.) Empty, 800 lbs. (363 kgs.)

Motor.—50 h.p. Gnome. Speed. 55 m.p.h. (90 km.)

Remarks.—The fixed tail area is 32 sq. feet. Body is entirely enclosed, stream line form. The passenger sits behind the pilot. Mounted on wheels and one long skid forward. Full description and details, Flight, 26th October, 1912.

Principal pilots have been the late E. Petre (who made in it the only flight through London), the late Lieut. Parke, R.N., S. Pickles, and L. R. Whitehouse. The machine has been flown with two passengers, in addition to the pilot.

Military work.—During 1912 five biplanes of the B.E. type were ordered by the British War Office. Several monoplanes were ordered by foreign governments.

FRENCH AEROPLANES.

Military Aviation.

In February, 1912, the then total of 208 effective aeroplanes were divided into "squadrillas" consisting of eight aeroplanes; attached to these eleven or twelve motor cars, one traction car and one fast car, also a repairing car and repairing van.

It was then estimated that at the end of 1912, 344 aeroplanes would be available for service.

The estimated personnel was provisionally fixed at 234 officer pilots, 210 scouts, 42 mechanics, 110 officers, 1,600 corporals or sappers and 550 privates.

Approximately £880,000 was spent in aviation during 1912, and £1,000,000 was estimated for future years.

The French military aviation centres are all upon somewhat the same footing as fortresses, and the greater part of the work comes under the head of "confidential." The principal school is at St. Cyr, which was specially selected because the ground is rough and mostly covered with small shrubs: it being held important to train officers from the first to rise and land on ground similar to that most likely to be found in war time. Each station is supplied with large portable wooden-framed hangars covered with canvas. These can be rapidly taken to pieces and re-erected. Each station is supplied with its own special motor transport.

All military machines are provided with a compass and map case in front of the pilot and sketching apparatus in front of the observer.

Although a few non-commissioned officers have been taught flying, the organization only contemplates the employment of commissioned officers as pilots. The age limit is 38.

On April 16th, 1913, the flying corps was modified. The principal features of the corps as now existing are as follows:—

Establishments.

1. Schools.

2. Special establishments, dealing with purchase, construction, and big repairs.

3. Directions. Administration of material.

4. Depots. A species of dockyards dealing with minor repairs, etc.

Administration.

There are three main groups, each commanded by a colonel. Each group consists of dirigibles and aeroplane "escadrilles," and is fully equipped with establishments, etc. The three centres are:—

1. Versailles.

2. Reims.

3. Lyon.

General.

All squadron units are made up of machines of the same make and power. Pilots are detailed as required to any particular unit, and liable to transfer from one to another, though in practice such transfers are rare.

Army Aeroplanes.

During 1912 nearly 500 machines were delivered to the Army, but a great many old machines have been scrapped. At the end of March, 1913, the force stood at 421 effective for war machines, plus an uncertain number of school machines and obsoletes.

About one-third or more of the effective aeroplanes were Farmans. The rest consisted of all leading French types, proportionated more or less to the productive capacity of these firms. Also certain other makes experimental.

Navy Aviation.

The Navy section of French military aviation is still in the "being formed" process. No data are yet available as to the ultimate force to be provided. At present the number of effective war machines is small. It is made up of hydro-avions of the following types:—Astra, Borel, Breguet, Caudron, Deperdussin, Donnet-Leveque, Farman, Paulhan-Curtiss, Sanchez-Besa, the total at end of March, 1913, being well under 20. There are also two special Bleriot type fitted with floats, which carry 330 lbs of explosive, are fitted with wireless, have a speed of 140 km.p.h. (85 m.p.h.), and a radius of about 600 miles (1,000 km.)

FRENCH AEROPLANES—PRIVATE.

Private Aeroplanes.

The total number of machines built in France during 1912 has been estimated at about 1,500. This includes military as well as private machines, also machines exported, and appears to be unduly generous even so. The actual total of machines commenced and completed in 1912 is nearer 1,000.

The number of private aeroplanes—excluding demonstration and school machines is small.

Note.—The monocoque is of wood and steel construction, the others wood only. The monocoque has coque body, the others ordinary rectangular section. Floats of the hydro as illustrated. For the rest the ordinary mono. is practically on the same lines as the 1912. The racer is somewhat on Deperdussin lines, but the body is built up inside. No fixed tail. The hydro. is an enlarged edition of the mono. Floats display nothing very original, except that a float under tail is interconnected with the rudder, and that the two front floats are fitted for being rowed. Fitted with a self-starter.

In each case.—

Construction.—All steel.

Landing chassis.—C consists of three wheels each protected by skids. The two main wheels, placed on either side of the centre of gravity, are fitted with patent "Oleopneumatic" shock absorbers. The steering wheel and the front skid have a spring suspension.

Military machines.—The 1912 sales of these were:—32 to France; 5 British; 3 Italian; 1 Swedish.

Steering.—The patented control system consists of a wheel mounted on a pivoted lever. The backward and forward movement of the entire system operates the elevator: the sideway movement warps the rear edge of the upper wings, and the rotation of the wheel steers the machine. The latter operation also governs the front wheel of the landing chassis, so that when on the ground the machine can be steered like a motor car.

Portability.—The main planes can be folded alongside of the fuselage. The machine can then be towed on any ordinary road, or be housed in places such as farm buildings, stables, &c.

Remarks.—The whole of the above can easily be converted into hydro-avions—two long narrow floats without steps. H. Farmans are of wood and steel construction; M. Farman, wood. In all 1913 biplanes the ailerons are inter-connected. All 1913 machines designed to carry one or in some cases two mitrailleuse, and special attention is paid to facility for taking down for transport and re-assembling. The 1911-12 H. Farmans had elevators forward, were a good deal longer, and had more surface than 1913 models. Ailerons not inter-connected. The M. Farmans generally as now, except that all planes, etc., had rounded edges. On September 11th, 1912, Foury, in an M. Farman military, made world's endurance record to date, 13 hrs. 22 min., covering 631 miles (1,017 km.) All models of this type, also the "big military," are fitted with the Doutre stabiliser. Fabric: "Aviator" Ramie.

Latest Hydro.—In March, 1913, a new hydro was produced experimentally. There is a boat body, without steps, carrying the motor which is chain connected with the propeller. Machine is fitted with wheels and skids as well.

ASTRA CLASS.

Astra Societe de Constructions Aeronautique, 13, Rue Couchot, and 121, Rue de Bellevue, Billancourt.

This Society was founded by Surcouf for the production of ordinary balloons. The first dirigible work was building part of the old Lebaudy in 1903, followed in 1906 by the Ville de Paris. The total number of dirigibles of this type completed by the end of 1912 stood at 14, one very large dirigible in hand for the French Army, and one small one for the British Navy, and another for the Russian Army.

Owing to changes in names, or owing to two names getting supplied to one ship, confusion frequently exists as to the names of the Astra dirigibles. The correct list is as follows:—

1. | Part of the LEBAUDY | 1903
2. | VILLE DE PARIS | 1906
3. | VILLE DE BORDEAUX | 1908
4. | VILLE DE NANCY | 1909
5. | Russian Military dirigible, KOMMISSIONNY, originally known as CLEMENT-BAYARD I | 1909
6. | COLONEL RENARD | 1909
7. | ASTRA-TRANSAERIENNE-VILLE DE PAU-VILLE DE LUCERNE[C] | 1909
8. | ESPANA (Spanish Military) | 1909
9. | VILLE DE BRUXELLES | 1910
10. | LIEUT. CHAURE (French Military) | 1911
11. | ADJUTANT RÉAU (French Military) | 1911
12. | ECLAIREUR CONTÉ (French Military) | 1912
13. | TRANSAERIENNE II | 1912
14. | ASTRA-TORRES I | 1911

[C] This ship has frequently figured as four different dirigibles.

The general features of the Astra class are: Non-rigid, weights distributed by means of a long girder hung under the gas bags, a long nacelle, and inflated stabilising shapes at the rear end of the balloon.

The Astra-Torres type are also non-rigid, but of trefoil section with a short nacelle.

The Compagnie Generale Transaerienne was first established in 1909 with Transaerienne I, and during the summers 1909, 1910 and 1911, this ship made a total of 273 ascents, carried 2590 passengers, and voyaged 7990 kilometres.

The Astra firm has dirigible hangers at Issy, Pau, Meaux, and Reims. Its constructional capacity is sufficient to build six dirigibles at any one time.

Uniform Dirigible Scale.

CLEMENT-BAYARD CLASS.

Usines Clement-Bayard, 33, quai Michelet, Levallois-Perret (Seine).

These dirigibles closely resemble the Astra class in some main particulars; but (excepting I) differ from them in the sharp sterns and absence of stabilisers on stern.

The ships of this class are:—

1 | CLEMENT-BAYARD | I(Kommissionny) | Russian Military
2 | " | II | British Military (wrecked)
3 | " | |
4 | " | IV (Adjutant Vincennot) | French Military
5 | " | V (Fleurus) | "
6 | " | VI | Private
7 | " | VII | French Military (building), To be of 17,000 m³.

ADJUTANT VINCENNOT. Military. (1911.) (Clement-Bayard IV.)

Maximum length, 251 feet (76.50 m.) maximum diameter, 43 feet (13.22 m.) volume, 7,500 m³.

Total lift.—Nearly 8 tons (8,000 kgs.) Useful lift, 2¾ tons (2717 kgs.)

Gasbags.—Continental rubbered fabric. Weight, 380 grammes per m². Strength 1,000 kg. per metre. Leakage under 10 litres per m² per 24 hours.

Motors.—2 Clement motors, 4-cylinder, of 130 h.p., each placed on either side of the motor space.

Speed.—35 m.p.h. (56 km.)

Propellers.—2 Chauvière. Diameter, 19¾ feet (6 m.) Placed one on either side of the motors, well above the level.

Steering.—Vertical steering by means of a treble horizontal rudder over the rear end of the car. Horizontal steering by means of 2 vertical rudders placed one on each side of the rear horizontal rudder.

Remarks.—The feature of this C.B. type, which distinguishes it from the Astra ships of about the same size, is the arrangement of the propellers and the use of a 2 speed gear in connection with these. Normally each motor drives its own propeller through two sets of gearing connected by a Cardan shaft. On stopping one motor, the stopped motor is unclutched from its propeller shaft, which is then connected up by chain drive to the opposite shaft. The running motor is then put on to a "low gear," so that it can make the revolutions necessary for obtaining full power, while the propellers run slower than before. The ratio of "low gear" to "high" is 2 to 1, so that a single motor will be running under its best conditions when well throttled down.

A sister, C. Bayard II was sold to the British Army, and wrecked or dismantled, 1911.

FRENCH DIRIGIBLES (Semi-rigid).

LEBAUDY CLASS.

Ateliers Lebaudy Frères, Moisson, par La Roche-Guyon (Seine-et-Oise).

DISTINCTIVE CHARACTERISTICS:

The cars are short and suspended from a long keel which is suspended close up to the gas bag, and is mostly covered in with fireproof canvas.

The rear end of the keel is expanded into fixed vertical and horizontal fins, and carries a vertical and a horizontal rudder.

The rear end of the gas bag is fitted with thin fixed planes (compare with the pear shaped or tubular fins of the "Astra" class).

The cars are provided underneath with an extraordinarily strong conical structure, which takes the shock of striking the ground and distributes it over the whole car.

Aeroplanes are now fitted, one each side of the keel, well forward.

FRENCH DIRIGIBLES (Non-rigid).

ZODIAC CLASS.

Société française de ballons dirigeables et d'aviation, Zodiac, 10 route du Havre, Puteaux (Seine).

These dirigibles were intended primarily for private pleasure purposes. Consequently they are designed to fly when filled with coal gas if necessary.

Every effort is made to render them easily transportable; the long girder frame by which the weight is distributed is made to take to pieces.

It is held in France that numbers of this class of vessel would form an invaluable asset in time of war, as each could be transported in a single cart, filled with a very few bottles of hydrogen, and when so filled could manuvre for some 6 hours at a speed which compares favourably with that of the standard types.

When the service of reconnaissance was performed, the vessel could be packed up and sent out of harm's way in an hour, whereas this could scarcely be done with a larger vessel on account of the quantity of hydrogen that would be required if it had to be filled afresh for each service. The mooring of an airship in the open during war requires such an amount of preparation and attention as to be a serious drawback to the alternative plan of keeping such vessels unfilled, while the sending of an airship back to its distant shed on each occasion means doubling the work that the ship is called upon to perform.

1. | ZODIAC I (Petit Journal)
2. | ZODIAC II (De la Vaulx)
3 | ZODIAC III
4 | ZODIAC IV | Dutch Military

GERMAN MILITARY CLASS—GROSS-BASENACH. (Semi-rigid)

Up to date, these vessels have been designed by Major Gross and Oberingenieur Basenach.

The utmost secrecy is observed as to their details.

The system of employing 2 ballonets has been borrowed from the Parseval type, and presumably the Parseval system of working the automatic valves has also been adopted.

In all other features, these ships appear to resemble the French Lebaudy type, the shape of the hulls being rather better.

PARSEVAL CLASS (Non-rigid).

Luftfahrzeug-Gesellschaft m.b.H, Berlin, W. 62.

When the "Motorluftschiff Studien Gesellschaft" was formed at the instigation of the German Emperor, a committee was formed to acquire an experimental airship of the most promising type. Major Von Parseval's first airship was selected, and since that time the above company has confined itself to improving this type, and to making exhaustive and costly researches, all of which have been embodied in successive ships.

The characteristic feature of every one of these craft is its unequalled portability. Almost all other so-called Non-rigid vessels distribute the load by means of a long girder which also serves as a car. This girder is awkward to pack up and transport. Parseval uses a comparatively small car, and distributes the weight by hanging it further below the balloon than usual, and also by using 2 ballonets which are placed one near each end of the gas bag.

These 2 ballonets enable the ship to be trimmed by merely pumping air into either at the expense of the other.

Another essential feature of the type is the system by which the valves are worked automatically. At the present time there is no other system of valve working so reliable as this.

A third essential feature of the class is the use of a swinging car, in such a manner that pitching, due to alterations of propeller thrust, is automatically checked by an alteration of the position of the centre of gravity.

A fourth feature is the use of limp propeller blades. A propeller of this type is very easily packed up.

The shape of these vessels is in accordance with the experiments of Professor Prandtl.

Ships of this class built or building (figures supplied by the Parseval Co.):—

EXPERIMENTAL PARSEVAL | 2,300 m³.
P. L. 1 | Kals. Ae. C | 3,200 m³.

(Of the above, the Experimental is no longer in existence, P. 2 is out of service, and P. L. 3 has been burned and destroyed).

PARSEVAL (P.L. 1). (1908.) (Belongs to the Kaiserl. Aero Club.) (Parseval class.)

Length, 197 feet (60 m.) max. diam. 31 feet (9.4 m) capacity, 113,000 c. feet (3,200m³) lifting power, 7,800 lbs. (3,583 kgs.)

Gas bag.—Cylindrical, with semi-conical front. Of rubber-proofed material in longitudinal strips. Pressure in ballonets and gas bag, 30 mm. of water.

Motor.—One 85 h.p. Daimler.

Fuel.—700 lbs. (325 kg.) 88 gallons (400 litres)

Speed.—20 m.p.h. (32 k.p.h.)

Propeller.—One 4-bladed. Semi-rigid Parseval.

This vessel was somewhat altered on being bought by the Society. Her essential principle is that she can be taken to pieces in a few minutes, and carried in a truck. Her main feature is that she has a ballonet at each end. This is described in the case of type A (P.L. 2). This class rise with the forward ballonet empty, and inclined up by the bow. The propeller is similar to that of P.L. 2. The car also is mounted on wire runners. She was originally 4,000 m³. capacity. Built 1908. Station: Bitterfeld. The car is at present in Deutsches Museum, Munich.

PARSEVAL P.L. 2 = P. I. Military. (1908.)

Built by the "Society for the Study of Motor Air Ships," and taken over by the German War Office.

Length, 197 feet (60 m.) maximum diameter, 34 feet (10.40 m.) capacity, 111,270 cubic feet (4,000 cubic m.) lifting power, 9,200 lbs. (4,180 kgs.)

Gas bag.—Front end semi-ellipsoidal with semi-axes 15.4 feet (4.7 m.) and 11.8 feet (3.6 m.), from which it increases to its maximum diameter. This is maintained for about two-thirds of its length, when it begins to taper to a point at the stern. Made of 2 layers of transverse strips of rubber proofed material, crossing each other diagonally. Fitted with a tearing strip.

Ballonets.—One at each end, together amounting to about one-quarter of the total capacity. Owing to this disposition, the trim can be altered, and steering effected in the vertical plane by filling either more than the other. Pressure in the ballonets and gas bag, 20 mm. of water pressure.

Motor.—4-cylinder 85 h.p. Daimler placed at one side of the car to give more room. 1,000 to 1,200 r.p.m.

Propellers.—12-1/3 feet (3.75 m.) diameter, 250 to 300 r.p.m. 4-bladed, the blades being of peculiar construction. When stopped, the fabric of which they are made hangs down limply; when running, these flaps fly out under centrifugal force.

Speed.—27 miles per hour. 43 kilometers per hour.

Car.—Length, 22-1/3 feet (6.8 m.) Width 4.1 feet (1.22 m.) Made of nickel steel, U bars, screwed together so as to take the pieces rapidly. The sides are lattice girders. The whole is boat shaped and covered with canvas. Contains motor, chart table; trail rope 480 feet (146 m.) long, weighing 220 lbs. (100 kg.) Wheel for horizontal steering at the bow. 110 gal. (500 litre) cask of petrol on the girders at the after point. 41 feet (12½ m.) below the gas bag. It is capable of swinging horizontally on wires running over rollers. Whereas without this device a forward swing of the car would lift the nose to a possibly dangerous extent, the free motion of the car shifts the centre of the gravity forward and so preserves stability.

Steering.—In vertical plane, by altering the trim. In horizontal plane, by a rudder of 80.7 sq. feet (7½ m²) immediately behind the vertical plane. Two fixed horizontal planes are placed at the rear end of the gas bag above the central line.

PARSEVAL II.

Table of weights:—

Gas bag | 1,653 | lbs.
Cordage | 220.5 | "
Trail rope | 220 | "
Car and motor | 529 | "
Fuel | 770 | "
Oil | 160 | "
Oil and fuel tanks, instruments, miscellaneous | 1,637 | "
Crew, passengers, ballast | 1,654 | "
Total | 6,834 | lbs.

Note.—This remarkably successful ship has performed a continuous flight of 11½ hours. She also remained at a height of 4,800 feet (1,500 m.) for 1 hour. She can be transported in 1 railway truck or 2 pair horse wagons, and be assembled and filled ready for ascent within 3 hours of arrival by train.

Built 1908. Station: Metz.

Remarks.—Built March, 1911, with a view to crossing the Atlantic from the Canaries to the Antilles. Re-constructed 1912. Proposed further re-construction in 1913.

SCHÜTTE-LANZ 1. Military. S.L. I.

(1911.) H. Heinrich Lanz, Rheinau bei Mannheim.

Maximum length, 426 feet (130 m.) maximum diameter, 60½ feet (18.40 m.) volume, 706,000 c. feet (20,000 m³.)

Total lift.—About 20 tons (20,000 kgs.) Useful lift.—About 5 tons (5,000 kgs.)

Gas bags.—These are of great strength and of unusual shapes, made to fit the interior, which is encumbered with cross stays. All but two of the bags are always full, and when the gas expands it flows into the remaining two, which are nearly empty at sea level, and full at 6500 feet (2,000 m.) A centrifugal pump is used for distributing the gas. There are 14 gas bags.

Motors.—2 Maybach of 270 h.p. each. The propellers are at the ends of the car, driven through 1 set of reduction gear. Speed.—38-43 m.p.h. About 59-64 k.p.h.

Propellers.—2 aft. Also 1 with its axis vertical.

Steering.—Vertical and horizontal rudders at both ends of the ship. Also see Propellers.

Remarks.—Two of these ships were under construction, and one was to be presented and one sold to the German government. The hull is built of special 3-ply wood made of Russian white fir; this wood is pressed into channel bars, angle bars, and all other requisite shapes. The strength of the hull is such that it can be supported at the ends without damage; its lightness is such that although the ship is nearly half as large again as Zeppelin II, yet the hull weighs about 3 tons less. Designed by Prof. Schütte.

In 1910, structural defects were found in Schütte I when the loads were applied. This has necessitated extensive alterations and much delay. In 1911 it was completed, and sold for £25,000 to the German Army.

SCHÜTTE-LANZ 2. Military. S.L. II. (1913.)

Building. Enlarged edition of above. 918,000 c. feet (26,000 m³.)]

ZEPPELIN type. Rigid.

Graf von Zeppelin, Friedrichshafen.

The features of this type are—A rigid framework of aluminium, a number of drum-shaped gas bags, and a thin outer cover.

At the end of March, 1913, the total of Zeppelins, limit and building was 16, including one (number 18) for Austria. Of these several had come to grief in various ways, and the actual total at the date mentioned, was:—

8 effective = 4 Army (of which one Z4 was still on trials), 1 naval and 3 private.

3 completing or building = 1 naval, 1 private and 1 for Austria.

Others projected but not actually in hand.

All are on the lines of the above plan, differing only in minor details, such as the provision of a cabin amidships, etc., and in dimensions.

ITALIAN MILITARY AVIATION.

ORGANISATION, etc.

The Battaglione Aviatori has its headquarters at Turin. In July, 1912, it was re-organised along the following lines:—

1 command at Turin.
1 flying work.
1 technical work.
2 troop duty.
6 at the aviation schools, with a certain number of mobile squadrillos.

The recognised grades are:—
a.a.p. aspirante allievo (learners).
a.p. allievo pilota (certificated pilots).
p. pilota militare (superior military brevet).

In flying work the superior pilots are mostly using Bleriots; the ordinary pilots Bleriot-Caproni, Bristol, Antonis, Deperdussins and Voisins.

The technical section chiefly supervises the theoretical instruction of the a.a.p.

The 2 companies on troop duty practical work, preparation for the schools.

FLYING SCHOOLS.

The military schools are:—

Aviano.—Central school. Size about 5×2 kilometres. Sheltered from all winds except westerly, by banks of trees. Numerous hangers.

Mirafiori (Turin).—Mixed military and civil school. Hangers. School machines confined to Asteria, Bleriot, Nieuport and Savary types.

Pordenone.—School for superior brevets. Treeless plain. Principal school machines Breguets and Farmans; but some Bleriots and Caproni.

S. Francesco al Campo.—M. Farman machines. At present for officers trained in France.

Somma Lombarda.—Camp school for Nieuports.

Venaria Reale.—Formed late in 1912. Bristol monos for certificated pilots.

GENERAL TRAINING.

50 officers in training during the first quarter of 1913.

Aspirants commence with instruction in the theory of heavier than air machines, resistance of material and particular instruction in the various type of aero motors in use. They are taken for flights as passengers.

All then go to the training camp about 80% for monoplane work, the remainder for biplanes.

Monoplanes. Special attention paid to teaching Gauchis Dessent.

Biplanes. Much shorter course. Principal feature: Vol Plané.

For the military brevet the examination is most comprehensive, special attention is paid to flying in wind, manoeuvring, climbing, good landings without inconvenience to passengers, cross country flights, etc. The course is generally modelled on war experiences.

TOTAL FLYING STRENGTH.

No particular distinction between naval and military aviators.

Total by end of June, 1913, to be about 225 certificated aviators of whom a fair percentage hold the superior brevet. In addition all the best civilian aviators are held at disposal.

Military Aeroplanes.

At the end of 1911 there were about 20 machines, mostly Bleriots and Farmans. The majority of these are still in use for school purposes.

At the end of March, 1913, the machines effective for war purposes were roughly as follows:—

Bleriot.
Bristol (mono.)
Caproni.
Deperdussin.
Farman.
Hanriot.
Nieuport.
Savary.

Total about 50, plus a number of school machines.

About 40 machines were on order, including 12 Bristol-Capronies.

Naval Aeroplanes.

Effective at end of March, 1913.

1 Calderara.
1 Guidoni-Farman.
4 or 5 others.

Notes: All the above are semi-rigid. The P and M are all of the same general type. Principal features of these ships, which were designed by Captains Crocci and Ricaldoni, are the shape of the envelope, (maximum diameter very far forward), keel and the box kite tail. The Citta di Milano (semi-rigid) is an enlarged Leonardo da Vinci (which see). Special feature is the keel built into the envelope. This serves as a nacelle.

Building.—One Parseval (P.L. 15) about the same size as the other (P.L. 17), which was completed first.

General Military Aviation.

This was originally formed as one body without distinction between army and navy. It was subsequently re-modelled on lines somewhat similar to the British Royal Flying Corps with naval and military wings.

Navy.

The naval section is superintended by Capt. K. Yamaji, I.J.N.

The naval headquarters are at Oihama (near Yokosuka).

The naval force at the end of 1912 consisted of 4 hydro-aeroplanes (2 Curtiss and 2 Farman). The available total of qualified naval aviators was 5.

Finance.

The total amount granted for aviation of the navy in 1912 (fiscal year) was 100,000 yen (£10,000).

For the year 1913 the estimates amount was 100,000 yen (but not approved yet).

Pay of Flying Officers.

The special pay for officers employed in aerial work is undecided.

Army.

The army wing is responsible for the dirigible. Aeroplanes are one or two Bleriots, a Grade, 2 Tokogawa, and a Farman.

Private Aviation.

There are some private aeroplanes being regularly flown in Japan. A number of aeroplanes have from time to time been invented by naval and military officers and private individuals, and some of them are in use. Inventors include Major Hino, naval constructor Narahara and Ushioki, Baron Iga, Baron Shigeno and Mr. Tsuzuki.

VLAICLU Monoplane.

Designed by Ouvret Vlaiclu. First shewn at the Vienna Exhibition, 1911. Modified; it flew very well indeed at Aspern, June, 1912. The 1912 model is of entirely novel type, a tail first monoplane with a propeller either end of the main planes, and a triangular tail aft. Principal details are:—Length, 34-2/3 feet (10.50 m.) Span, 30 feet (9.15 m.) Height, 12 feet (3.65 m.) Wing frame in three sections with gap between. Motor, 50 h.p., Gnome chain driven. Fuselage, old style; landing chassis on three wheels only, with a single ash skid in front. Covered in engine driving the 31 foot propeller shaft for the 2 propellers. Rear tail consists of 2 fixed planes, a triangular damping plane and a triangular keel plane. Forward, an elevator and two semi-circular rudders (double faced). From this combination remarkable results are achieved, and all gyrostatic effect from the propellers eliminated. Control, horizontal wheel on column. Elevator depressed or otherwise by action on column. Note.—At Vienna, 1912, this machine took first prize for the smallest circle and also for accurate bomb-dropping. The original machine was purchased by the Roumanian Army.

RUSSIAN.

General Note.—In the number of military machines and general attention to aviation Russia is only second to France. There are no effective machines of Russian design, but the Aviataka, Dux & Lomatuk firms build at home under foreign license, and there is also the Kennedy school (Anglo-Russian).

RUSSIAN MILITARY AVIATION.

Army Aviation.

Early in 1912, under the presidency of the Grand Duke Alexander, the special school of the Volunteer Aerial Association was finally formed at Sevastopol for the winter and Gatchina for the summer.

June 1912. Vote for 150 aeroplanes (140 to be built at home). Vote 1,050,000 roubles for new school at Tauride.

November, 1912. Military trials results. (1) Sikorsky in a Sikorsky. (2) Haber in a M. Farman. (3) Boutmy in a Nieuport.

December, 1912. Aeronautical school re-organised. Put under control of one commandant, one assistant, and four juniors. Course made seven months—15 pupils per school at a time. A one month course in aeroplanes, aerial motors, etc. Of the pupils, 10 will be selected for aeroplanes. New flying school established at Taskend in Turkestan.

March, 1913. New schools established at Moscow, Odessa and Omsk.

At the end of 1911 the total number of military aeroplanes was about 100. At the end of March, 1913, the total number was about 250, of which about 150 were modern. Principal types: Albatross, Aviatik, Bristol, Deperdussin, Farman, Nieuport, Rumpler, there being an average of 20 of each. The majority built under Russian license in Russia. The number of actual military pilots was 72. There is, however, a special volunteer corps of about 36 private aviators, bringing the available total to 108 or thereabouts.

Navy Aviation.

July, 1912. Lieut. Andreadi, 50 h.p. Nieuport, did a flight with stops from Sevastopol to St. Petersburg.

September, 1912. Special naval aerodrome for hydro-avions ordered for Golodai Island, near Petersburg, bringing total of military and naval aerodromes to 6. Sikorsky hydro-avion acquired. Also an M. Farman ditto. New naval station projected at Libau.

October, 1912. Naval purchase of several Curtiss hydro-avions after trials at Sevastopol.

At the end of March, 1913, the approximate effective force was as follows (all hydros, or capable of being so fitted): 1 Astra, 1 Breguet, 2 Donnet-Leveque, 1 Farman, 4 Paulhan Curtiss, 2 Nieuport (50 h.p.), 1 Sikorsky. (A number of others on order.)

Early in 1913 experiments were carried out with a combination of floats and skids, invented by M. Lobanoff, of Moscow. This proved equally effective on land or water.

Army Aeroplanes.

There is a military aerodrome at S. Stefano, with Amerigo, Renzel and Thanlau as instructors.

In March, 1913, there were about 12 monoplanes (Harlans & Reps), and one or two biplanes. Only one seems actually to have been used. Several other aeroplanes were captured during the war—generally in their packing cases unopened. In April, 50 machines were reported ordered in Germany.

General Note.—In the early nineties, Professor Langley and the Bros. Wright were experimenting with heavier-than-air machines, but general interest in the subject is quite recent. Though some small dirigibles exist, American attention is mainly devoted to aeroplanes. Ballooning was quite the thing in 1907-11, but has languished.

It is stated that there are certainly no less than two thousand people in the U. S. A. who have built flying machines. The greater percentage of these have been home-made copies of standard machines. Individual builders of copies and freaks have diminished greatly in numbers, and there remains a few well-established manufacturers.

Although inventors are still prolific in the Patent Office and clubs numerous, the general public takes very slight intelligent interest in aviation. The majority of clubs are inactive.

In the year 1912 commercial development seemed to have great possibilities. The copyists were being weeded out and competent aeronautical constructors financed by adequate means began operations on systematic business lines. The latter half of the year saw a great slump. In the spring of 1913 prospects looked greatly improved, and there was generally increased activity.

U. S. A. AERO CLUBS.

An attempt has been made here to give the name of every aero club that has been formed recently in the United States, or has been in existence for a long time. It is believed this list covers every club in the United States.

Many of these clubs are nothing but a name. They were formed to conduct meets or exhibitions, given by the various aeroplane concerns engaged in this business. Many clubs are not incorporated. Others have no organisation, being run by principals of boys' schools or classes.

Clubs even affiliated with the Aero Club of America have no members' meetings, nor have they in many cases even meeting rooms. There are but a half-dozen live aero clubs worthy the name in America. Three clubs own balloons, which are rented to members for ascensions. Little attempt is made by more than one or two associations to popularise aeronautics, to encourage experimenters, or to indulge in scientific work.

The Aero Club of America, the Aeronautical Society and Aero Club of Illinois, are the principal organisations. The Ae. C. represents the F.A.I., and has a beautiful club house. The Aeronautical Society has rooms in the United Engineering Building, conducts well-attended lectures twice a month, and has grounds on Straten Island (for hydro-aeroplanes and aeroplanes).

U.S.A. MILITARY AVIATION.

U. S. ARMY AEROPLANE SPECIFICATIONS. (1912).

SPEED SCOUT MILITARY AEROPLANE.

(1) Carry one person with the seat located to permit of the largest possible field of observation. (2) Ascend at the rate of 1500 feet in three minutes, while carrying fuel for one hour's flight. (3) Carry fuel for a three hours' flight. (4) Must be easily transportable by road, rail, etc., and easily and rapidly assembled and adjusted. (5) The starting and landing devices must be part of the machine itself, and it must be able to start without outside assistance. (6) The engine must be capable of throttling. (7) The engine will be subject to endurance test in the air of two hours' continuous flight. (8) Speed in the air of at least 65 miles an hour. (9) Capable of landing on and arising from ploughed fields. (10) The supporting surfaces must be of sufficient size to insure safe gliding in case the engine stops. (11) The efficiency and reliability of the system of control must have been demonstrated before the purchase order is placed. The aeroplane must be capable of executing a figure eight within a rectangle 500 yards by 250 yards, and without decreasing its altitude more than 100 feet at the completion of the figure eight. This test to be made by aviator alone without carrying extra weight. (12) The extreme width of the aeroplane supporting surfaces must not exceed 40 feet.

SCOUT MILITARY AEROPLANE.

(1) The aeroplane must carry two persons with seats located to permit of the largest possible field of observation for both. (2) The control must be capable of use by either operator from either seat. (3) The machine must be able to ascend at least 2000 feet in ten minutes while carrying a weight of 600 lbs. including the aviator and passenger, 150 lbs. of gasoline, and extra weight to make 600 lbs. All of the extra weight must be carried on the engine section and not distributed over the wings. (4) The fuel and oil capacity must be sufficient for at least four hours continuous flight. This will be determined by a trial flight of at least one half-hour, measuring the consumption of gasoline while carrying the passenger and weight stated in paragraph 3. (5) Same as No. 4 above. (6) Same as No. 5 above. (7) The engine must be of American manufacture and capable of throttling to run at reduced speed. (8) Same as No. 7 above. This test will be made with aviator and passenger, extra weight and fuel enumerated in paragraphs 3 and 4. (9) The aeroplane must develop a speed in the air of at least forty miles an hour. This test will be made with aviator and passenger, extra weight and fuel enumerated in paragraphs 3 and 4. The maximum speed must not exceed sixty-five miles per hour. (10) Same as No. 9 above. This test will be made with aviator, passenger, extra weight and fuel enumerated in paragraphs 3 and 4. (11) Same as No. 10 above. (12) Same as No. 11 above. (13) Same as No. 12 above.

In 1913 additional requirements specified enclosed body, bullet-proof armour, .75 chrome steel, for engine and aviator, provision of necessary instruments and wireless, with, as desirable features, silencer and cut-out, self-starter and an efficient stabilising device.

At end of March, 1913, the effective Army aeroplanes consisted of three 50 h.p. Wrights, one Wright-Burgess, several old machines.

The Navy had two Wright-Burgess hydros and a few nondescripts. A Burgess flying boat since added.

The estimate for Army effectives at end of the present year (1913) is 21 (5 Burgess, 6 Curtiss, 10 Wright).

U.S.A. PRIVATE AVIATORS (to end of 1911).

(The number against any name is, unless otherwise stated, the Ae. C. America pilot certificate number. Only a few American aviators have bothered to obtain the Ae. Certificate. America produces a large number of aviators who fly for pleasure or exhibitions only and have not gone into competitions under International Rules. These consequently do not bother about certificates; but most of those recorded could easily obtain them, if they cared to try.)

CURTISS.

Curtiss Aeroplane Co., Hammondsport, N.Y. Glenn H. Curtiss in 1907 and 1908 was a member of the Aerial Experiment Association, formed by Dr. and Mrs. Alexander Graham Bell. This Association built four machines, each along the lines of one of the four engineers belong to the Association, F. W. Baldwin, Lieut. T. E. Selfridge, G. H. Curtiss and J. A. D. McCurdy. The last built was the June Bug, designed by Curtiss and was the most successful. In the spring of 1908, the Association was disbanded and The Aeronautical Society gave Curtiss an order for an aeroplane with carte blanche as to design. He produced a 4 cyl. machine, Curtiss engine, and flew it. A duplicate was hurriedly built, 8 cyl. engine installed, and taken to Europe for the first Gordon Bennett, which he won. Returning, the same type was continued with minor improvements. Later the front elevator was brought closer in, finally discarded, and the fan tail adopted and this remains the standard land machine to-day. In April, a military tractor was built and flown.

On January 26th, 1911, first successful flights were made with a hydroaeroplane, at the Winter camp at San Diego, Calif. This had two floats tandem. One was finally adopted and great success was achieved, and remains standard at the present time. With this machine various experiments were made. It was altered in a tractor for one occasion, it was lifted on board warships; made into triplane, etc.

In 1912 he brought out his present type of flying boat. This is being rapidly developed and minor changes in details are made in practically every machine put out.

In May, 1913, he produced a special 4-passenger flying boat for a customer on special order.

Note.—In addition to those tabulated, special small racing machines have been built, as well as similar machines with extra sections simply added either side for Army use.

SELLERS. Quadruplane.

Matthew B. Sellers, R.F., D2, Norwood, Ga. Has been successfully experimenting for a number of years with a staggered quadruplane, and has given the aviation world a number of valuable papers. His aim is to fly successfully with the least possible horse power. For several years he has been making flights with various engines delivering from 5 to 6 h.p. on careful test. The actual thrust has been measured and recorded in late 1911 experiments. Details in Aeronautics, June, 1909; October, 1909; November, 1910; January, 1911; January, 1912. No actual details of the machine are available, but it follows closely the patent drawings (see references). He is one of the few real scientific flying men in the U.S.A. The original machine with slight changes was still flying at end of 1912 with only 5 h.p. B.H.P. The flying speed is 20 m.p.h.

THOMAS Biplanes.

Thomas Bros., Bath, N.Y., O.W., and W.T. Thomas began experimenting and flying in 1908 with a machine on the order of a Curtiss. In the winter of 1909-10, a type of their own was produced and was flown during 1911 by Walter Johnson in exhibitions. In 1912 they continued the same type, with refinements. In 1913 they adopted the overhanging top plane type, but of the same general high order of construction.

HISTORICAL AIRCRAFT.

In the following pages an attempt has been made to include photographs of all aeroplanes of the past six years, which, for one reason or another, "made history" in their own day.

While many are merely freak machines, which in the light of present knowledge seem ridiculous, the germ of modern practice is to be found in many other aircraft illustrated in this cemetery of dead ideals; and it is worth noting that at least one constructor, who is one of the first in the field to-day, commenced operations with machines which were entirely "freaks."

AUSTRIAN.

WELS & ETRICH (1908). Original form of the modern Etrich (q.v.).

HIPSSICH (1908). Tandem mono. with one propeller before and another in rear of rear plane.

NEMETHY (1908). The first "Aviette."

SOLTAU (1910). An ornithopter based on the earlier ideas of Adehmar de la Hault (see Belgium).

BELGIAN.

DE LA HAULT (1907). One of the earliest attempts at an ornithopter. No flights.

DE LA HAULT II. (1910-11). The ornithopter principle applied to a monoplane. No success met with.

D'HESPEL (1909-10). Single plane and suspended body. Early example of enclosed body. No flights.

BRAZIL.

SANTOS-DUMONT XIX. This little machine, surface only 9 m². made an extraordinary sensation in France in 1909. It flew at the then incredible speed of 65 m.p.h. (100 k.p.h.) Santos-Dumont presented all rights to the world soon afterwards, and a large number were built before it was realised that only an extremely light weight pilot could fly in one. Few of the copies ever left the ground.

BRITISH.

AVRO (1906). This 24 h.p. biplane, designed by A. V. Roe, was the first British machine to leave the ground.

AVRO (1907). Tractor triplane of only 9 h.p. This flew in Lea Marshes—the lowest horse power yet flown in Europe to the present day.

CODY (1909). Development of a much earlier machine. This one was a general laughing stock for a long time; but it was the direct predecessor of the machine (not very materially different) which was an easy first in the British Army aeroplane trials, 1912.

DE HAVILLAND (1909). The performances of this machine secured a Government appointment for its aviator-designer.

HOWARD WRIGHT (1908-09). The first machine in the world in which special attention was paid to securing a stream line body and minimised wind resistance.

HUMPHREY (1908-09). Earliest British attempt at a hydro-aeroplane; possibly the earliest design ever produced anywhere.

HUNTINGDON (DUNNE II) (1910). One of the earliest aeroplanes in existence—designed by Captain Dunne about 1905-06, previous to the secret experiments of the British War Office in Scotland, on the Duke of Atholl's estate. Assigned to Prof. Huntingdon in 1910. Made a few short flights.

PORTE (1908). Designed by Lieut. Porte, R.N., in conjunction with Lieut. Pirrie, R.N. This machine, on which the former well known aviator commenced his flying career, was smashed up in preliminary trials as a glider on Portsdown Hill, Portsmouth. Its design apparently preceded the Goupy in the use of staggered planes.

"SAFETY" (1909-10).

SEDDON. (1910). Designed by Lieut. Seddon, R.N.

SHORT (1910). The first machine to Short's own design. (The tail here shown is a specially large one fitted by Moore-Brabazon).

VALKYRIE (1910). This was one of the first "tail first" machines to be designed. The experimental machine (also known as the A.S.L.), was completed in Feb., 1910.

DANISH.

ELLEHAMMER (1905). On 12th September, 1906, this machine made the first free flight in Europe. On 28th June, 1908, it won the prize at Kiel for the first flight in Germany (distance, 47 m.) It was a tractor biplane with a revolving Ellehammer motor. It also had a pendulum seat as a stabilising device.

FRENCH.

ANTOINETTE IV (1909). In this machine Latham made the first attempt to fly the Channel, 19th July, 1909.

BLERIOT IV (1907-8).

In 1909 the famous Bleriot XI was built. This did very well at Reims, 1909. On 25th July, 1909, Bleriot made the first Cross-Channel flight in the machine illustrated below.

Bleriot XI.

This machine had length, 23 feet (7 m.) Span, 25¾ feet (7.80 m.) Area, 167 sq. feet (15½ m².) Aspect ratio 4½ to 1. Motor, 22-25, 3 cylinder Anzani. Speed, about 45 m.p.h. (73 k.m.) Special features: Fixed wings with rounded edges. Twin elevator and fixed surface tail.

BOUSSON-BORGNIS (1907-08).

BREGUET (1906). The first Breguet, known as Breguet Gyroplane I. Made a flight in October, 1906, being the first helicopter to leave the ground.

BREGUET-RICHET II bis. (1909). A large and unsuccessful development of the gyroplane.

BREGUET IV (1910). On its appearance, this machine was generally laughed at and nicknamed the "Coffee Pot," till in Aug., 1910, it made a world's record by carrying six, and later proved itself superior in stability to anything then existing.

CHAUVIÉRE (1909-10). Attempt to develop a monoplane with propellers in rear. The idea has been resuscitated for some 1913 military monoplanes.

COLLOMB (1907-09). Ornithopter, from which great things were once expected.

CORNU (1908). An early helicopter for which flights were claimed, but have also been denied.

D'EQUIVELLY (1907-08). Interesting example of the strange machines devised by pioneers.

H. FARMAN (1907). This famous machine is the first Voisin, and the one on which H. Farman taught himself to fly. It was the first machine to make a turn in the air. Won the Deutsh-Archdeacon Grand Prix, 13th January, 1908, with a flight of 1 minute, 28 seconds. The extra third plane was added later. An Austrian Syndicate subsequently bought the machine.

H. FARMAN (1908). Farman's first idea of a monoplane. It proved too heavy to fly with the power provided. Was eventually sold to a German officer. Three sets of wings and entirely enclosed body.

GABARDINI (1909-10). Very early hydro-aeroplane, antedating the Fabre.

GIVAUDIN (1908-09). Built by the Vermorel Co. The first conception of an idea which has since attracted a certain class of inventor in Germany, Italy and the U.S.A.

MILITARY (1909). The first special military aeroplane ever built. It was specially designed by Capt. Dorand, for what were then held to be the aerial necessities of the French Army. The planes were placed well above the body, giving the pilot a very clear uninterrupted view.

PISCHOFF-KOECHLIN (1906 or earlier). Dates from the days when a box-kite was the elementary idea in design, and the accepted position of the aviator lying prone.

PISCHOFF-KOECHLIN (1908). Very early example of a tractor biplane. The extra span of the upper plane is also of interest. The machine had twin mono-elevators aft and also twin rudders.

R.E.P. (1908). Early example of enclosed stream line body. Apparently the first machine in which steel construction appeared.

VOISIN (1908). The first European aeroplanes to fly with any real success.

VUITTON-HUBER (1908). Early helicopter.

VUIA (1908). Earliest known machine with folding wings.

WITZIG-LIORE-DUTILLUEL (1908-09). First or one of the first appearances of the idea of a series of staggered planes, with which Sellers has ever since experimented in the U.S.A.

GERMAN.

BEILHARZ. (1909). First design in which a completely closed in body figured.

GEISLER (1908).

ITALIAN.

MILLER (1908-09). First aeroplane to be designed and constructed by Italians.

SWISS.

DUFAUX (1908-09). First Swiss machine.

U.S.A.

BOKOR (1909). The third American machine to leave the ground; the second purely U.S. one.

CALL II (1909).

CYGNET II (1908). Designed by Dr. Graham Bell, of the Aeronautical Society of America. Bell (Canadian), Glen Curtis (U.S.), Herring (U.S.), and Burgess (Canadian). It made short flights.

ENGLISH (1909). In 1909 extraordinary claims were made for this machine and great things expected. On a full power trial in its shed it broke loose, and smashed itself against the roof. No recorded outdoor results.

HERRING-BURGESS (1910).

HULBERT (1910). This strange machine built in Switzerland by Dr. Dane Hulbert, achieved several flights. The planes were placed longitudinally instead of in the usual way.

JUNE BUG (1908-09). Famous machine of its era. Built by the Aeronautical Society of America (see Cygnet II). Second machine to fly in the U.S.A. Did 2000 miles before being broken up.

KIMBALL (1909). First machine in which a large number of propellers was attempted. Failed.

LOOSE (1910).

LUYTIES OTTO (1908).

MOISSANT (1910). Built entirely of aluminium. Designed by the late John Moissant. Failed.

Note.—So far as possible this is a complete list of all the aero engines of any importance.

Data are confined to what is now being made or actually in use; untested "show novelties" are ignored.

In the case of some engines it has for various reasons proved impossible to obtain full data in time for inclusion in this edition.

In a general way these lists are confined to aeroplane engines.

Dependability

In carburettors there is no greater essential than dependability, and—

The dependability of the White & Poppe is such as ensures a never-failing and invariable efficiency.

That's why it is the favourite with many of the leading Airmen of the day.

Our Booklet describes it fully, and we shall be delighted to send you copy.

Burberry Aeroplane Outfit.

BURBERRY

AEROPLANE
EQUIPMENT.

DESIGNED BY EXPERTS is workmanlike both in design and detail, and permits absolute freedom for arms and limbs. Made in wind and weatherproof Gabardine, lined throughout with Camel Fleece or Quilted Eiderdown, it maintains phenomenal warmth under the severest conditions.

BURBERRY GABARDINE is remarkably airylight, yet affords perfect protection against wind, cold or rain, and is so strong that broken stays cannot penetrate its dense texture.

Mr. C. Grahame-White:—"I take this opportunity of thanking you for the suit I wore on my memorable flight and feel I cannot recommend the material too highly where warmth and comfort are required."

THE FULL PROJECT GUTENBERG LICENSE
PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK

To protect the Project Gutenberg-tm mission of promoting the free
distribution of electronic works, by using or distributing this work
(or any other work associated in any way with the phrase "Project
Gutenberg"), you agree to comply with all the terms of the Full Project
Gutenberg-tm License (available with this file or online at
http://gutenberg.net/license).

Section 1.  General Terms of Use and Redistributing Project Gutenberg-tm
electronic works

1.A.  By reading or using any part of this Project Gutenberg-tm
electronic work, you indicate that you have read, understand, agree to
and accept all the terms of this license and intellectual property
(trademark/copyright) agreement.  If you do not agree to abide by all
the terms of this agreement, you must cease using and return or destroy
all copies of Project Gutenberg-tm electronic works in your possession.
If you paid a fee for obtaining a copy of or access to a Project
Gutenberg-tm electronic work and you do not agree to be bound by the
terms of this agreement, you may obtain a refund from the person or
entity to whom you paid the fee as set forth in paragraph 1.E.8.

1.B.  "Project Gutenberg" is a registered trademark.  It may only be
used on or associated in any way with an electronic work by people who
agree to be bound by the terms of this agreement.  There are a few
things that you can do with most Project Gutenberg-tm electronic works
even without complying with the full terms of this agreement.  See
paragraph 1.C below.  There are a lot of things you can do with Project
Gutenberg-tm electronic works if you follow the terms of this agreement
and help preserve free future access to Project Gutenberg-tm electronic
works.  See paragraph 1.E below.

1.C.  The Project Gutenberg Literary Archive Foundation ("the Foundation"
or PGLAF), owns a compilation copyright in the collection of Project
Gutenberg-tm electronic works.  Nearly all the individual works in the
collection are in the public domain in the United States.  If an
individual work is in the public domain in the United States and you are
located in the United States, we do not claim a right to prevent you from
copying, distributing, performing, displaying or creating derivative
works based on the work as long as all references to Project Gutenberg
are removed.  Of course, we hope that you will support the Project
Gutenberg-tm mission of promoting free access to electronic works by
freely sharing Project Gutenberg-tm works in compliance with the terms of
this agreement for keeping the Project Gutenberg-tm name associated with
the work.  You can easily comply with the terms of this agreement by
keeping this work in the same format with its attached full Project
Gutenberg-tm License when you share it without charge with others.

1.D.  The copyright laws of the place where you are located also govern
what you can do with this work.  Copyright laws in most countries are in
a constant state of change.  If you are outside the United States, check
the laws of your country in addition to the terms of this agreement
before downloading, copying, displaying, performing, distributing or
creating derivative works based on this work or any other Project
Gutenberg-tm work.  The Foundation makes no representations concerning
the copyright status of any work in any country outside the United
States.

1.E.  Unless you have removed all references to Project Gutenberg:

1.E.1.  The following sentence, with active links to, or other immediate
access to, the full Project Gutenberg-tm License must appear prominently
whenever any copy of a Project Gutenberg-tm work (any work on which the
phrase "Project Gutenberg" appears, or with which the phrase "Project
Gutenberg" is associated) is accessed, displayed, performed, viewed,
copied or distributed:

This eBook is for the use of anyone anywhere at no cost and with
almost no restrictions whatsoever.  You may copy it, give it away or
re-use it under the terms of the Project Gutenberg License included
with this eBook or online at www.gutenberg.net

1.E.2.  If an individual Project Gutenberg-tm electronic work is derived
from the public domain (does not contain a notice indicating that it is
posted with permission of the copyright holder), the work can be copied
and distributed to anyone in the United States without paying any fees
or charges.  If you are redistributing or providing access to a work
with the phrase "Project Gutenberg" associated with or appearing on the
work, you must comply either with the requirements of paragraphs 1.E.1
through 1.E.7 or obtain permission for the use of the work and the
Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
1.E.9.

1.E.3.  If an individual Project Gutenberg-tm electronic work is posted
with the permission of the copyright holder, your use and distribution
must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
terms imposed by the copyright holder.  Additional terms will be linked
to the Project Gutenberg-tm License for all works posted with the
permission of the copyright holder found at the beginning of this work.

1.E.4.  Do not unlink or detach or remove the full Project Gutenberg-tm
License terms from this work, or any files containing a part of this
work or any other work associated with Project Gutenberg-tm.

1.E.5.  Do not copy, display, perform, distribute or redistribute this
electronic work, or any part of this electronic work, without
prominently displaying the sentence set forth in paragraph 1.E.1 with
active links or immediate access to the full terms of the Project
Gutenberg-tm License.

1.E.6.  You may convert to and distribute this work in any binary,
compressed, marked up, nonproprietary or proprietary form, including any
word processing or hypertext form.  However, if you provide access to or
distribute copies of a Project Gutenberg-tm work in a format other than
"Plain Vanilla ASCII" or other format used in the official version
posted on the official Project Gutenberg-tm web site (www.gutenberg.net),
you must, at no additional cost, fee or expense to the user, provide a
copy, a means of exporting a copy, or a means of obtaining a copy upon
request, of the work in its original "Plain Vanilla ASCII" or other
form.  Any alternate format must include the full Project Gutenberg-tm
License as specified in paragraph 1.E.1.

1.E.7.  Do not charge a fee for access to, viewing, displaying,
performing, copying or distributing any Project Gutenberg-tm works
unless you comply with paragraph 1.E.8 or 1.E.9.

1.E.8.  You may charge a reasonable fee for copies of or providing
access to or distributing Project Gutenberg-tm electronic works provided
that

- You pay a royalty fee of 20% of the gross profits you derive from
the use of Project Gutenberg-tm works calculated using the method
you already use to calculate your applicable taxes.  The fee is
owed to the owner of the Project Gutenberg-tm trademark, but he
has agreed to donate royalties under this paragraph to the
Project Gutenberg Literary Archive Foundation.  Royalty payments
must be paid within 60 days following each date on which you
prepare (or are legally required to prepare) your periodic tax
returns.  Royalty payments should be clearly marked as such and
sent to the Project Gutenberg Literary Archive Foundation at the
address specified in Section 4, "Information about donations to
the Project Gutenberg Literary Archive Foundation."

- You provide a full refund of any money paid by a user who notifies
you in writing (or by e-mail) within 30 days of receipt that s/he
does not agree to the terms of the full Project Gutenberg-tm
License.  You must require such a user to return or
destroy all copies of the works possessed in a physical medium
and discontinue all use of and all access to other copies of
Project Gutenberg-tm works.

- You provide, in accordance with paragraph 1.F.3, a full refund of any
money paid for a work or a replacement copy, if a defect in the
electronic work is discovered and reported to you within 90 days
of receipt of the work.

- You comply with all other terms of this agreement for free
distribution of Project Gutenberg-tm works.

1.E.9.  If you wish to charge a fee or distribute a Project Gutenberg-tm
electronic work or group of works on different terms than are set
forth in this agreement, you must obtain permission in writing from
both the Project Gutenberg Literary Archive Foundation and Michael
Hart, the owner of the Project Gutenberg-tm trademark.  Contact the
Foundation as set forth in Section 3 below.

1.F.

1.F.1.  Project Gutenberg volunteers and employees expend considerable
effort to identify, do copyright research on, transcribe and proofread
public domain works in creating the Project Gutenberg-tm
collection.  Despite these efforts, Project Gutenberg-tm electronic
works, and the medium on which they may be stored, may contain
"Defects," such as, but not limited to, incomplete, inaccurate or
corrupt data, transcription errors, a copyright or other intellectual
property infringement, a defective or damaged disk or other medium, a
computer virus, or computer codes that damage or cannot be read by
your equipment.

1.F.2.  LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
of Replacement or Refund" described in paragraph 1.F.3, the Project
Gutenberg Literary Archive Foundation, the owner of the Project
Gutenberg-tm trademark, and any other party distributing a Project
Gutenberg-tm electronic work under this agreement, disclaim all
liability to you for damages, costs and expenses, including legal
fees.  YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE

Section  2.  Information about the Mission of Project Gutenberg-tm

Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of computers
including obsolete, old, middle-aged and new computers.  It exists
because of the efforts of hundreds of volunteers and donations from
people in all walks of life.

Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come.  In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future generations.

Section 4.  Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg-tm depends upon and cannot survive without wide
spread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine readable form accessible by the widest
array of equipment including outdated equipment.  Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.

The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States.  Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements.  We do not solicit donations in locations
where we have not received written confirmation of compliance.  To
SEND DONATIONS or determine the status of compliance for any
particular state visit http://pglaf.org

While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.

International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States.  U.S. laws alone swamp our small staff.

Please check the Project Gutenberg Web pages for current donation
methods and addresses.  Donations are accepted in a number of other
ways including including checks, online payments and credit card
donations.  To donate, please visit: http://pglaf.org/donate

Section 5.  General Information About Project Gutenberg-tm electronic
works.

Professor Michael S. Hart is the originator of the Project Gutenberg-tm
concept of a library of electronic works that could be freely shared
with anyone.  For thirty years, he produced and distributed Project
Gutenberg-tm eBooks with only a loose network of volunteer support.

Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as Public Domain in the U.S.
unless a copyright notice is included.  Thus, we do not necessarily
keep eBooks in compliance with any particular paper edition.

Most people start at our Web site which has the main PG search facility:

http://www.gutenberg.net

This Web site includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
