Their first three or four days' journeys were without any event worth being chronicled. They travelled full twenty miles each day. The Southerners had become quite skilful in the management of their snow-shoes, and they skimmed along upon the icy crust at the rate of three or four miles an hour.
Marengo and his sledge gave them very little trouble. There was full sixty pounds weight upon it; but to the huge dog this was a mere bagatelle, and he pulled it after him without any great strain. His harness was neatly made of moose-skin, and consisted of a collar with a back strap and traces--the traces meeting behind, where they were attached to the head of the sledge. No head-gear was necessary, as Marengo needed not to be either led or driven. The sledge consisted of two or three light planks of smooth wood, laid alongside each other, and held together by transverse bands. In front it turned up with a circular sweep, so as not to "plough" the snow; and at the top of this curved part the traces were adjusted. The load was, of course, carefully packed and tied, so that the overturning of the vehicle did no damage whatever, and it could be easily righted again. Marengo required no one to guide him, but followed quietly in the tracks of the snow-shoes, and thus avoided the trees, rocks, and other inequalities. If a rabbit or other creature started up, Marengo knew better than to go galloping after it; he felt that he had a more important duty to perform than to throw away his time upon rabbit-hunting.
Each night a spot was chosen for the camp by the side of some lake or stream, where wood could be obtained for their fire. Water was got by breaking a hole in the ice, and the little tent was always set up in a sheltered situation.
Upon the fifth day after leaving the log-hut the woods began to grown thinner and more straggling; and towards night of the same day they found themselves travelling through a country, where the timber only grew here and there in small clumps, and the individual trees were small and stunted. Next day still less timber was seen upon their route; and when camping-time came, they were obliged to halt at a spot where nothing but willows could be procured for their fire. They had, in fact, arrived upon the edge of that vast wilderness, the Barren Grounds, which stretches in all its wild desolation along the Northern half of the American continent from the Great Slave Lake even to the shores of the Arctic Sea on the north, and to those of Hudson's Bay on the east.
