Exceptionally fine garage accommodation is available, and a "supply of spare parts ismaintained.

Coan, which is to be won outright two years in succes-sion, or three years in all, and the winner will also receive a replica ; the second prize is ^5, and the third £3. Entriesclose on September 8, and should be sent to the Secretary, at the Royal Hotel, Clacton-on-Sea, the fee being 5 s. IN turning over some old papers the other day we weregreatly interested to come across a copy of the Beardmore Ne&s of May 28, 1919. Contained in it was an article byMr. G. Tilghman Richards, F.R.Ae.S., M.I.M.E., the Manager of the Beardmore Aviation Dept. at Dalmuir, and laterevents have shown that his foresight was more than justified. It was an appeal to develop aircraft and aviation on soundlines as distinct from the hurried improvisation of war-time. Mr. Tilghman Richards emphasised the especial need forthe development of a cheap, safe and thoroughly reliable power, and pointed out that a commercial aeroplane in dailycommission burns approximately its own value in fuel per annum. With individuals of such broadminded and clearvision in charge of affairs it is not surprising that things are progressing at Dalmuir. ONE of the results of the visit of Mr. D. C. Hutchinsonto the other side is an expansion of the Titanine organisation in the States. In order to speed up deliveries and obviateany delay, the executive offices of the U.S. company have been transferred to the Works at Union, N.J.

Wireless Telephone Developments ELSEWHERE in this issue we refer to the successful "calling up," by telephone, of their aeroplane City of London while flying to Paris on August 19, by Messrs. Instone and Co., which marks a step forward in the experiments in wireless telephony which have been carried on for some time by the ~ Air Ministry with the co-operation of the Marconi Co., and V_. the G.P.O. After the machine had left the Croydon Aero- ?'u • drome for Paris about midday, with ten persons on board, : • it was found to be urgent to convey some special instruc- :' tions to Mr. Chattaway, the pilot, on business connected = with coal supply at Marseilles, which had been affected by the strike at Cardift. Mr. Samuel Instone telephoned to . ... the Air Ministry asking for their help, and was enabled by them to have the ordinary telephone into which he was \ >' speaking in his own office connected with their wireless telephone installation at Croydon. By the combined tele- phones he got through to Mr. Chattaway and after one or two calls Mr. Chattaway replied and said he had just passed over Folkestone. Mr. Instone gave him the instructions which he was anxious to communicate, and as an additional test of the capabilities of the telephone under these special conditions, Mr. Chattaway read a passage frorq a newspaper, which Mr. Instone was able to follow. At one point com- munication was interrupted at the telephone exchange and was restored again in the ordinary way after conversation with the operator there. Mr. Instone said he could hear the whirring of the pro- pellers of the machine and the voice of the pilot was as audible as if he were makirig an ordinary trunk call ; he could hear as plainly as if he were listening to somebody speaking to him from Paris.
