Note 143 — Chapter IV

"According to Mr. M'Gregor (Brit. Amer., vol. ii., p. 525), the Ottawa, or Grand River, is said to have its source near the Rocky Mountains, and to traverse in its windings a distance of 2500 miles. The more sober statement of Bouchette attributes to the Ottawa a course of about 450 miles before joining the St. Lawrence."—Bouchette, vol. i., p. 187.

"A tremendous scene is presented at the eastern part of Lake St. Louis, where the St. Lawrence and its grand tributary, the Ottawa, rush down at once and meet in dreadful conflict. The swell is then equal to that produced by a high gale in the British Channel, and the breakers so numerous, that all the skill of the boatmen is required to steer their way. The Canadian boatmen, however, are among the most active and hardy races in the world, and they have boats expressly constructed for the navigation of these perilous channels. The largest of these, called, it is not known why, the Durham boat, is used both here and in the rapids of the Mohawk. It is long, shallow, and nearly flat-bottomed. The chief instrument of steerage is a pole ten feet long, shod with iron, and crossed at short intervals with small bars of wood like the feet of a ladder. The men place themselves at the bow, two on each side, thrust their poles into the channel, and grasping successively the wooden bars, work their way toward the stern, thus pushing on the vessel in that direction. At other times, by the brisk and vigorous use of the oar, they catch and dash through the most favorable lines of current. In this exhausting struggle, however, it is needful to have frequent pauses for rest, and in the most difficult passages there are certain positions fixed for this purpose, which the Canadians call pipes."—H. Murray's Hist. Descr. of America, vol. ii., p. 473.
