The envelope of this dirigible was rendered airtight by means of internal rubber coating, with a thinner film on the outside. Coal gas, used for inflation, formed a suitable fuel for the engine, but limited the height to which the dirigible could ascend. Such trials as were made were carried out with the dirigible held captive, and a speed of 15 feet per second was attained. Full experiment was prevented through funds running low, but Haenlein鈥檚 work constituted a distinct advance on all that had been done previously. A subsequent report of the Board of Ordnance and Fortification to the Secretary of War embodied the144 principal points in Major Macomb鈥檚 report, but as early as March 3rd, 1904, the Board came to a similar conclusion to that of the French Ministry of War in respect of Clement Ader鈥檚 work, stating that it was not 鈥榩repared to make an additional allotment at this time for continuing the work.鈥?This decision was in no small measure due to hostile newspaper criticisms. Langley, in a letter to the press explaining his attitude, stated that he did not wish to make public the results of his work till these were certain, in consequence of which he refused admittance to newspaper representatives, and this attitude produced a hostility which had effect on the United States Congress. An offer was made to commercialise the invention, but Langley steadfastly refused it. Concerning this, Manly remarks that Langley had 鈥榞iven his time and his best labours to the world without hope of remuneration, and he could not bring himself, at his stage of life, to consent to capitalise his scientific work.鈥?

The beginning of the competition consisted in assembling the machines against time from road trim to flying trim. Cody鈥檚 machine, which was the only one to be delivered by air, took 1 hour and 35 minutes to assemble; the best assembling time was that of the Avro, which was got into flying trim in 14 minutes 30 seconds. This machine came to grief with Lieut. Parke as pilot, on the 7th, through landing at very high speed on very bad ground; a securing wire of the undercarriage broke in the landing, throwing the machine forward on to its nose and then over on its back. Parke was uninjured, fortunately; the damaged machine was sent off to Manchester for repair and was back again on the 16th of August. � PS.

A propeller burst while the vessel was in the air, and one blade, flying toward the envelope, tore in it a great gash; the airship crashed to earth, and the two officers and two non-commissioned officers who were in the car were instantaneously killed. Eighteen months later an offer was made by Government of ten thousand rupees to any one who should give up Khansah,鈥攖he dacoit being a very notorious robber and murderer. His own relatives responded promptly to this appeal, and Khansah speedily found himself in durance vile. Mr. Tucker failed to identify the man in Court; but other evidence was forthcoming, and Khansah, being convicted, was hung. Charlotte, when noting down particulars of the above stirring episode, observes: 鈥榃e cannot feel too thankful to a merciful God for my precious George鈥檚 preservation.鈥?The brief account which she copied out from the letter of a friend in India ends with these words: 鈥楳y husband tells me he (Mr. Tucker) acted with great spirit, and showed much cool, determined courage, and deserved great credit; but from being almost a stranger to the habits of this country, he failed in his attempt to capture the dacoit.鈥? The Daily Mail had offered a prize of 锟?,000 for the first Cross-Channel flight, and Hubert Latham set his mind on winning it. He put up a shelter on the French coast at Sangatte, half-way between Calais and Cape Blanc Nez. From here he made his first attempt to fly to England on Monday the 19th of July. He soared to a fair height, circling, and reached an estimated height of about 900 feet as he came over the water with every appearance of capturing the Cross-Channel prize. The luck which dogged his career throughout was against him, for, after he had covered some 8 miles, his engine stopped and he came down to the water in a series of long glides. It was discovered afterward that a small piece of wire had worked its way into a vital part of the engine to rob Latham of the honour he coveted. The tug that came to his rescue found him seated on the fuselage of his Antoinette, smoking a cigarette and waiting for a boat to take him to the tug. It may be remarked that Latham merely assumed his Antoinette would float in case he failed to make the English coast; he had no actual proof. I am beginning chemistry, a most unusual study.
