The face of the Indian child was considerably puffed up and swollen with their bites; the men could procure scarcely any sleep during the night, and the insects continued to harass them next morning, as they proceeded.

On one occasion Captain Clark went on shore and ascended a hill after one of the bighorns; but the mosquitoes were in such multitudes that he could not keep them from the barrel of his rifle long enough to take aim.

About ten o'clock, however, a light breeze sprung up from the northwest, and dispersed them in some degree.

Captain Clark then landed on a sand-bar, intending to wait for Captain Lewis, and went out to hunt.

But not finding any buffalo, he again proceeded in the afternoon; and having killed a large white bear, camped under a high bluff exposed to a light breeze from the southwest, which blew away the mosquitoes.
