Airships past and present, together with chapters on the use of balloons in connection with meteorology, photography and the carrier pigeon . d been abandoned on account of the strong wind blowingon the day of his visit. In so far as the outsider is concerned,not the least mysterious part of the affair seems to be theproposal to sell the invention to the French Government. The work done by Professor Montgomery in California does A. I 114 AIR-SHIPS PAST AND PKESENT. not seem to have been so successful. He built an aeroplane forthe Jesuits of the monastery Santa Clara. His intention wasto raise it to a height of about 2,500 feet by means of a Mont-goljiere, and then to cut it adrift. On July 19th, 1905, after aseries of successful experiments, one of the sails broke after themachine had started from the balloon. The apparatus felldirectly to the ground and the driver was killed on the spot. Mention must also be made of the work done by Archdeaconin Paris. His aeroplane was towed by a motor-boat, travellingat 25 miles an hour, in a direction opposed to the wind, whichwas blowing at 4 miles an hour. It was constructed after the. ^M Fig. 6G.—Langleys flying machine on the Potomac. (From the Illustrierte Aeronautische Mitteilungen.) fashion of a Hargrave kite in Surcoufs balloon factory. At thefront there were two sails, 33 ft. by 6 ft. 6 in., and at the backtwo other sails with an area of 220 square feet; the rudder, withan area of 32 square feet, was placed at the front. The weightof this machine without driver was 6 cwt., and it was mountedon two small boats after the manner adopted by speaking, it turned out to be very stable, and roseto heights of 150 ft. But it often fell into the river, over whichthe flight took place, and on one occasion it turned over com-pletely, sustaining serious damage. Lately a good deal has been heard of another type of flyingmachine. It is proposed to run the machine along the level bythe aid of a motor until such a speed
