On the ninth of April the voyagers reached the point at which they were to leave tidewater, fifty-six miles above the mouth of the Multnomah, or Willamette. They were now at the entrance of the great rapids which are known as the Cascades of the Columbia, and which occupy a space on the river about equal to four miles and a half. They were still navigating the stream with their canoes, camping sometimes on the north side and sometimes on the south side of the river. This time they camped on the north side, and during the night lost one of their boats, which got loose and drifted down to the next village of the Wahclellahs, some of whom brought it back to the white men’s camp and were rewarded for their honesty by a present of two knives. It was found necessary to make a portage here, but a long and severe rainstorm set in, and the tents and the skins used for protecting the baggage were soaked. The journal goes on with the narrative thus:-- We determined to take the canoes first over the portage, in hopes that by the afternoon the rain would cease, and we might carry our baggage across without injury. This was immediately begun by almost the whole party, who in the course of the day dragged four of the canoes to the head of the rapids, with great difficulty and labor. A guard, consisting of one sick man and three who had been lamed by accidents, remained with Captain Lewis (and a cook) to guard the baggage. This precaution was absolutely necessary to protect it from the Wahclellahs, whom we discovered to be great thieves, notwithstanding their apparent honesty in restoring our boat; indeed, so arrogant and intrusive have they become that nothing but our numbers, we are convinced, saves us from attack. They crowded about us while we were taking up the boats, and one of them had the insolence to throw stones down the bank at two of our men.
