From the very first the conditions did not show themselves favourable
for the attempt. The wind was blowing at the rate of six or seven yards
a second. The change of temperature from the balloon-house to the cool
morning air had somewhat condensed the hydrogen gas of the balloon, so
that one end flapped about in a flabby manner. Air was pumped into the
air reservoir, inside the balloon, but still the desired rigidity was
not attained. But, more discouraging yet, when the motor was started,
its continuous explosions gave to the practised ear signs of mechanical
discord.
Nevertheless, Santos-Dumont, with his sleeves rolled up, fixed himself
in his basket. His eye took a careful survey of the entire air-ship lest
some preliminary had been overlooked. He counted the ballast bags under
his feet in the basket, he looked to the canvas pocket of loose sand at
either hand, then saw to his guide-rope.
There is a very great deal to look after in managing such a ship, and it
requires a calm head and a steady hand to do it.
"Near the saddle on which I sat," he writes, "were the ends of the
cords and other means for controlling the different parts of the
mechanism--the electric sparking of the motor, the regulation of the
carburetter, the handling of the rudder, ballast, and the shifting
weights (consisting of the guide-rope and bags of sand), the managing
of the balloon's valves, and the emergency rope for tearing open
the balloon. It may easily be gathered from this enumeration that an
air-ship, even as simple as my own, is a very complex organism; and the
work incumbent on the aëronaut is no sinecure."
Several friends shook his hand, among them Mr. Deutsch. The place was
very still as the man holding the guide-rope awaited the signal to let
go. Then the little man in the basket above them raised his hands and
shouted.
