construction. We now
saw that the section of the boat covered with buffalo-skins on which
hair had been left answered better than the elk-skins, and leaked but
little; while that part which was covered with hair about one-eighth of
an inch retained the composition perfectly, and remained sound and
dry. From this we perceived that had we employed buffalo instead of
elk skins, not singed them so closely as we did, and carefully avoided
cutting the leather in sewing, the boat would have been sufficient even
with the present composition; or had we singed instead of shaving the
elk-skins, we might have succeeded. But we discovered our error too
late; the buffalo had deserted us, and the travelling season was so
fast advancing that we had no time to spare for experiments; therefore,
finding that she could be no longer useful, she was sunk in the water,
so as to soften the skins, and enable us the more easily to take her to
pieces.

"It now became necessary to provide other means for transporting the
baggage which we had intended to stow in her. For this purpose we shall
want two more canoes; but for many miles--from below the mouth of the
Musselshell River to this place--we have not seen a single tree fit to
be used in that way. The hunters, however, who have hitherto been sent
after timber, mention that there is a low ground on the opposite side of
the river, about eight miles above us by land, and more than twice that
distance by water, in which we may probably find trees large enough for
our purposes. Captain Clark determined, therefore, to set out by land
for that place with ten of the best workmen, who would be occupied in
building the canoes till the rest of the party, after taking the boat to
pieces, and making the necessary deposits, should transport the baggage,
and join them with the other six canoes.

"He accordingly passed over to the opposite side of the river with his
party next day, and proceeded on eight miles by land, the distance by
water being twenty-three and three quarter miles. Here he found two
cottonwood trees; but, on cutting them down, one proved to be hollow,
split at the top in falling, and both were much damaged at the bottom.
He searched the neighborhood, but could find none which would suit
better, and therefore was obliged to make use of those which he had
felled, shortening them in order to avoid the cracks, and supplying the
deficiency by making them as wide as possible. They were equally a
