Capt. Lewis, June 13, 1805--Goodrich had caught half a douzen very fine trout and a number of both species of the white fish. these trout (caught in the falls) are from sixteen to twenty three inches in length, precisely resemble our mountain or speckled trout in form and the position of their fins, but the specks on these are of a deep black instead of the red or goald colour of those common to the U.' States. these are furnished long sharp teeth on the pallet and tongue and have generally a small dash of red on each side behind the front ventral fins ; the flesh is of a pale yellowish red, or when in good order, of a rose red.
Capt. Lewis, March 14, 1806--The mountain or speckled trout are found in the waters of the Columbia within the mountains. they are the same of those found in the upper part of the Missouri, but are not so abundant in the Columbia as on that river. we never saw this fish below the mountains, but from the transparency and coldness of the Kooskooske I should not doubt it's existing in that stream as low as it's junction with the S. E. branch of the Columbia.
