       Pincus Brauner and A. J. Smith constructed together a biplane, which proved the second
apparatus built at the Park to succeed in making good flights. In general outline, this also
somewhat resembled the Society's machine, but had features that were entirely the inventions
of the builders, and many of the small construction details were simpler and superior to any-
thing that had previously been done. Both Mr. Smith and Mr. Brauner made a number of
short flights, and the machine was exhibited at Madison Square Gardens. But eventually
Mr. Brauner, in takng a second step in the air to reach a greater height, raised his front
control too acutely, and fell backwards, smashing the apparatus almost entirely, but himself
escaping unhurt. The results, however, were highly encouraging.
     Dr. Walden tried out his big tandem apparatus with the Society's motor, and was
testing upon it the varying efficiency of a number of propellers. Unfortunately, one night he
left the machine out in the open, and a heavy wind storm arising, battered the apparatus
into a heap of wreckage before the watchman oculd take any steps to save it. Meanwhile,
however, the doctor has two more machines on the way.
     F. H. Lindsay, unable to find on the market a suitable motor for his midget machine,
started to build one for himself.
     R. E. Ernst constructed an apparatus in which the principle of air compression was
to be utilized. The air was drawn into the interior of a sort of cabin by means of fan
Dr. W. H. Walden's Tandem Biplane

propellers in the cabin walls, and was to escape through the floor. Engine trouble has
so far prevented the completion of the demonstration.
     Octave Jean built an elaborate arrangement of feathering fans, but the construction
work proved too weak.
     W. J. Diefenbach has laid out a very fine biplane, 45 ft. in spread and of excellent work-
manship, and hopes to have it completed in the early days of the New Year. It promises
to be one of the most notable macnines turned out at the Society's shops.
     Although their surfaces and contrls have long been completed, the Brothers lawrence
have been held up by the difficulty of finding an engine of at once sufficeint power and
necessary lightness. Otherwise they are ready to assemble and try out at any time.
     The third machine to get into the air, and the most successful, was the biplane of
Dr. Wm. Greene. Dr. Greene, who began building early in the year, was all but ready for
the June exhibition, and was paid a high compliment by Glenn H. Curtiss, who adopted
his method of fixing the upright struts to the main beams. Dr. Greene's machine was 40 ft.
in spread, and the surfaces, which are 6 1/2 ft. from fore to aft and 5 ft. apart, are
