An intermediate type that once did much service, and still does a little, is the white man's flat-bottomed boat, which could be {27} paddled, rowed, or sailed, according to build and circumstances. The common punt is the best known form of it; the dory by far the handiest all round; the cargo barge the biggest; and the old-fashioned 'bateau' the most characteristically Canadian. The modern 'bateau' is to be found only among keeled sailing craft. But the old 'bateau,' which Wolfe's local transport officers spelt _battoe_, was more of a rowboat. It was sharp at both ends, wall-sided, and fitted with oars, poles, and a square sail. The bottom had some sheer--that is, it was curved up at each end--but less than the top. Four men rowed, the fifth steered, and three tons of miscellaneous goods or thirty-five barrels of flour made a fair cargo. Bateaux like this were the craft in which the United Empire Loyalists went up the St Lawrence to settle Upper Canada. Afterwards the size and crew were increased till the average cargo amounted to about four tons and a half. But the Durham boat, introduced by American traders from the Mohawk valley, soon became a successful rival, which was not itself supplanted till canals enabled still larger craft to pass from one open water to another. The Durham was larger than the bateau; long, light, and shallow. It had a not quite flat {28} bottom and a moderate sheer in the sides. The best bateaux and Durhams were made with strong white oak bottoms and light fir sides. The bark canoe gave place to the boat, step by step, as civilized intercourse advanced. It disappeared first from the great national highway of the St Lawrence and the Lakes, where the French began using bateaux and sailing craft as early as the seventeenth century. During the eighteenth the boat gained steadily on the canoe, which was more and more confined to the Indians. The local craft in chief civilized use on both sides during the fight for Canada was the bateau; and the best crews then and afterwards were the French-Canadian voyageurs.
