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 at a loss for wood of which they might make handles for their axes, the eyes of which not being round, they were obliged to split the timber in such a manner that thirteen of the handles broke in the course of the day, though made of the best wood they could find for the purpose, which was the chokecherry.
"The rest of the party took the frame of the boat to pieces, deposited it in a cache or hole, with a draught of the country from Fort Mandan to this place, and also some other papers and small articles of less importance."

Early emigrants across the continent were so afflicted by these insects that the air at times seemed full of gray clouds of them.

It was the custom of the wayfarers to build a "smudge," as it was called, a low, smouldering fire of green boughs and brush, the dense smoke from which (almost as annoying as the mosquitoes) would drive off their persecutors as long, as the victims sat in the smoke.
