“In the course of the day (October 17, 1805), Captain Clark, in a small canoe with two men, ascended the Columbia.  At the distance of five miles he passed an island in the middle of the river, at the head of which was a small but not dangerous rapid.  On the left bank, opposite to this island, was a fishing-place consisting of three mat houses.  Here were great quantities of salmon drying on scaffolds; and, indeed, from the mouth of the river upward, he saw immense numbers of dead salmon strewed along the shore, or floating on the surface of the water, which is so clear that the fish may be seen swimming at the depth of fifteen or twenty feet.  The Indians, who had collected on the banks to observe him, now joined him in eighteen canoes, and accompanied him up the river.  A mile above the rapids he came to the lower point of an island, where the course of the stream, which had been from its mouth north eighty-three degrees west, now became due west.  He proceeded in that direction, until, observing three house’s of mats at a short distance, he landed to visit them.  On entering one of these houses, he found it crowded with men, women, and children, who immediately provided a mat for him to sit on, and one of the party undertook to prepare something to eat.  He began by bringing in a piece of pine wood that had drifted down the river, which he split into small pieces with a wedge made of elkhorn, by means of a mallet of stone curiously carved.  The pieces of wood were then laid on the fire, and several round stones placed upon them.  One of the squaws now brought a bucket of water, in which was a large salmon about half dried, and, as the stones became heated, they were put into the bucket till the salmon was sufficiently boiled for use.  It was then taken out, put on a platter of rushes neatly made, and laid before Captain Clark, while another was boiled for each of his men.  During these preparations he smoked with such about him as would accept of tobacco, but very few were desirous of smoking, a custom which is not general among them, and chiefly used as a matter of form in great ceremonies.

“After eating the fish, which was of an excellent flavor, Captain Clark set out and, at the distance of four miles from the last island, came to the lower point of another near the left shore, where he halted at two large mat-houses.  Here, as at the three houses below, the inhabitants were occupied in splitting and drying salmon.  The multitudes of this fish are almost inconceivable.  The water is so clear that they can readily be seen at the depth of fifteen or twenty feet; but at this season they float in such quantities down the stream, and are drifted ashore, that the Indians have only to collect, split, and dry them on the scaffolds.  Where they procure the timber of which these scaffolds are composed he could not learn; but as there is nothing but willow-bushes to be seen for a great distance from this place, it rendered very probable what the Indians assured him by signs, that they often used dried fish as fuel for the common occasions of cooking.  From this island they showed him the entrance of the western branch of the Columbia, called the Tapteal, which, as far as could be seen, bears nearly west and empties about eight miles above into the Columbia, the general course of which is northwest.”
