He also provided himself with three thoroughly tested
iron anchors, and a light but strong silk ladder fifty feet
in length.
He at the same time carefully weighed his stores of
provision, which consisted of tea, coffee, biscuit, salted
meat, and pemmican, a preparation which comprises many
nutritive elements in a small space. Besides a sufficient
stock of pure brandy, he arranged two water-tanks, each
of which contained twenty-two gallons.
The consumption of these articles would necessarily,
little by little, diminish the weight to be sustained, for it
must be remembered that the equilibrium of a balloon
floating in the atmosphere is extremely sensitive. The
loss of an almost insignificant weight suffices to produce a
very noticeable displacement.
Nor did the doctor forget an awning to shelter the
car, nor the coverings and blankets that were to be the
bedding of the journey, nor some fowling pieces and rifles,
with their requisite supply of powder and ball.
Here is the summing up of his various items, and their
weight, as he computed it:
Ferguson........................... 135 pounds.
Kennedy............................ 153 "
Joe................................ 120 "
