FEBRUARY 8, 1913. upon the subject, but we think that the phrasing of this finding is well worth keeping in mind. We will now pass on to a consideration of some other aspects of the question. One of the outstanding comments relates to the need for protecting vital parts of the aeroplane from evil con sequences of failure in the external parts of engines, and thus relates to the proper design and arrangement of cowls. Another point of importance emphasized in the report is that the 100-b.p. Gnome should not be over hung. Several cases of failure in Gnome engine gudgeon and lug end pins having been investigated, the report adversely criticises the design and construction, and recom mends an alteration. Similarly, the report draws attention to the liability of straining the connecting rod through careless tightening of the piston valve in Gnome engines. As against this, it is at least satisfactory to note that the Report lays the bogey of gyroscopic force to rest very comfortably by estimating that the effect may be com- ® ® The International Maritime Cup. THE full regulations of the International Cup presented by M. Jacques Schneider were passed by the F.A.I, at the meeting in Paris last week. In addition to the Trophy valued at .£1,000 a sum of ,£1,000 will be deposited for each of the first three years with the club in charge of the competition. For the first competition the Aero Club of France will be in charge of the arrangements. The date of the contest each year must be between April 1st and November 15th, the date to be announced before March 1st. Should the cup be won by one national club three times within five years it will become its property. • For this year the course will be 150 nautical miles entirely over the sea and over a closed circuit of not less than 5 nautical miles. r Mr. C. H. Pixton just ready to start from the Four Winds Aerodrome, Madrid, for a flight on his Bristol monoplane, with the Infanta of Spain, who occupies the front seat, and is wearing a fine wire mask for protection against the wind. mwm pared " with that of a small gust, of known direction, and should cause no difficulty to the flyer." The accidents to Capt. Hamilton and Maj. Gerrard are clearly regarded as engine accidents, except so far as a fractured propeller may have originated the failure of the overhung engine in the former machine. The stresses on the wing spars for the Dep. and the Bristol were calculated, and the Report recommends that the duplicate Bristol monoplane now at Larkhill be withheld from practice pending further investigation. Among other recommendations that the Committee offers to constructors are those to the effect that wings should be designed to be safe without external drift wires ; that lift wires should not be attached to the under carriage ; that they should be protected as much as possible from accident while the machine is running on the ground; that they should be duplicated, with their attachments of course; that control wires should be made of cable ; and that fabric should be more securely fastened to the upper side of the wing, so that it alone can carry the whole load. ® ® The Gordon-Bennett Race. IT will be seen from the official notices of the Royal Aero Club that it is probable that the course for this year's race for the Gordon- Bennett Trophy will be about 10 kiloms. round. According to the decision of the F.A.I., the full distance for the race shall be 200 kiloms., "cross-country a>niliori" over a closed circuit of not less than 5 kiloms. The Hydro-Aeroplane Brevet. As announced in our last issue the F.A.I, has approved of a special pilot's certificate for hydro-aeroplanes upon similar lines to the land certificate. While holders of the latter will not need to re-qualify for the former, the special hydro-aeroplane certificate will not be available for flying over land until the holder has carried out landing tests and had the certificate endorsed accordingly.
