“The camp became absolutely uninhabitable in consequence of the multitude of mosquitoes; the men could not work in preparing skins for clothing, nor hunt in the timbered low grounds; there was no mode of escape, except by going on the sand-bars in the river, where, if the wind should blow, the insects do not venture; but when there is no wind, and particularly at night, when the men have no covering except their worn-out blankets, the pain they suffer is scarcely to be endured. There was also a want of meat, for no buffalo were to be found; and though elk are very abundant, yet their fat and flesh is more difficult to dry in the sun, and is also much more easily spoiled than the meat or fat of either deer or buffalo. “Captain Clark therefore determined to go on to some spot which should be free from mosquitoes and furnish more game. Having written a note to Captain Lewis, to inform him of his intention, and stuck it on a pole at the confluence of the two rivers, he loaded the canoes at five in the afternoon, proceeded down the river to the second point, and camped on a sand-bar; but here the mosquitoes seemed to be even more numerous than above. 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. About eleven o’clock, however, the wind became very high and a storm of rain came on, which lasted for two hours, accompanied with sharp lightning and loud peals of thunder. “The party rose, next day, very wet, and proceeded to a sand-bar below the entrance of Whiteearth River. Just above this place the Indians, apparently within seven, or eight days past, had been digging a root which they employ in making a kind of soup. Having fixed their tents, the men were employed in dressing skins and hunting. They shot a number of deer; but only two of them were fat, owing probably to the great quantities of mosquitoes which annoy them while feeding.”
