  bravely sacrificed set after set of his beautifully made and costly little four-bladed pro-
pellers; but he overcame the trouble in the end. The difficulty was really due to the
terrific starting speed of his motor. The use of a friction clutch, made by a fellwo mem-
ber, Adrien C. Beckert, solved the problem
     There were, by this time, many machines on the way to completion at the Park. The
first among them, after Mr. Kimball's, to get out upon the track was the big triplane
constructed by Morris Bokor. Mr. Bokor had for some months been in the employ of
Mr. Kimball, and built his triplane during his spare hours and on Sundays. His machine
was mainly notable for its dihedral rear rudders, and for a pendulum arrangement which,
carrying both the engine and operator, was to give automatic lateral stability. The prin-
cipal surfaces were 28 ft. by 6 ft. 6 in., the upper pair spaced 6 ft. apart, and the lower ones
separated by 5 ft. The engine was a British-American 26 h. p. driving two 8-ft. propellers of
6 ft. 6 in. pitch, and proved to be of insufficient power to raise the apparatus, which weighed
much over half a ton. To decrease the weight, Mr. Bokor replaced his wheeled chassis
by light skids, and adopted a wheeled truck for launching. Still, however, his apparatus
clung with distressing affection to Mother Earth.
     But one Saturday afternoon it moved a bit on top of the truck in running at high
speed down the track. Mr. Bokor reported a near-flight, and was more certain even than
he had ever been that the next day he would take to the air.

     Mr. Bokor made many changes, and eventually took his machine to Arlington, N. J.,
where it won a prize of $500 for excellence of construction, the first money prize ever
won by a flying machine in America. Subsequently he took it to Westbury, L. I. But it
never go over its persistent refusal to leave the safety of the solid earth.
