The author enjoyed the great privilege of descending the Dalles in the _D. S. Baker_ in the year 1888, Captain Troup being in command. At that strange point in the River, the whole vast volume is compressed into a channel but one hundred and sixty feet wide at low water and much deeper than wide. Like a huge mill-race this channel continues nearly straight for two miles, when it is hurled with frightful force against a massive bluff. Deflected from the bluff, it turns at a sharp angle to be split in sunder by a low reef of rock. When the _Baker_ was drawn into the suck of the current at the head of the "chute" she swept down the channel, which was almost black, with streaks of foam, to the bluff, two miles in four minutes. There feeling the tremendous refluent wave, she went careening over and over toward the sunken reef. The skilled captain had her perfectly in hand, and precisely at the right moment, rang the signal bell, "Ahead, full speed," and ahead she went, just barely scratching her side on the rock. Thus close was it necessary to calculate distance. If the steamer had struck the tooth-like point of the reef broadside on, she would have been broken in two and carried in fragments on either side. Having passed this danger point, she glided into the beautiful calm bay below and the feat was accomplished. Captain J. C. Ainsworth and Captain James Troup were the two captains above all others to whom the company entrusted the critical task of running steamers over the rapids. In the _Overland Monthly_ of June, 1886, there is a valuable account by Captain Lawrence Coe of the maiden journey of the _Colonel Wright_ from Celilo up what they then termed the upper Columbia. This first journey on that section of the River was made in April, 1859. The pilot was Captain Lew White. The highest point reached was Wallula, the site of the old Hudson's Bay fort. The current was a powerful one to withstand, no soundings had ever been made, and no boats except canoes, bateaux, flatboats, and a few small sailboats, had ever made the trip. No one had any conception of the location of a channel adapted to a steamboat. No difficulty was experienced, however, except at the Umatilla Rapids. This is a most singular obstruction. Three separate reefs, at intervals of half a mile, extend right across the River. There are narrow breaks in these reefs, but not in line with each other. Through them the water pours with tremendous velocity, and on account of their irregular locations a steamer must zigzag across the River at imminent risk of being borne broadside on to the reef. The passage of the Umatilla Rapids is not difficult at high water, for then the steamer glides over the rocks in a straight course.
