A general landing was immediately made at the foot of the hill, and as the five canoes came up the baggage was prepared in bundles and packages for being carried, the canoe-paddles and poles securely tied in bundles, and the canoes lifted from the water and dried in the sun to make the transportation of them as light as possible, and mended and pitched wherever they leaked. It was found that the whole baggage, canoes and all, could be arranged for eleven back-loads, this being the precise number of our carriers, white and red; and being ready, Ozawindib led the way, having a single canoe for his share, and he was soon followed by the whole line, each one of our sitters falling in this line, charged with the particular instrument of his observation, or record of it. The hill was steep, and the footing soft and yielding in the crumbling diluvion, and the scene, as the party struggled up the ascent, presented quite a study for the picturesque. Lieutenant Allen carried his canoe-compass, which I had had mounted by an artisan of Detroit; Dr. Houghton grasped his hortus siccus under his arms; Mr. Johnston, our interpreter, had his pipe and fowling-piece, and Mr. Boutwell had wellnigh lost his pocket-bible and notes, while staying himself against the treacherous influence of a steep sand cliff. While the party thus took their way over the hill to cross a peninsula of a mile or two, and strike the river above the junction of the Naiwa River, I went to observe the rapids. The river, at this point, is forced through a narrow gorge, where the water descends with loud murmuring over a series of rapids, which form a complete check to navigation. The portage is two miles. I judged the entire descent of the channel, from the beginning to the terminus of the portage, to be forty-eight feet. Boulders of the peculiar northern sienite, highly charged with hornblende, and of trap-rock, or greenstone, quartz, and sandstone, were scattered over this elevation, and mixed with the more finely comminuted portions of the same rocks, and of amygdaloids and schistose fragments. Among these, I observed some specimens of the zoned agate, which identifies the stratum with the extensive drift formation of the upper Mississippi. It would seem that extensive amygdaloidal strata formerly extended over these heights, which have been broken down by the fierce and general rush of the oceanic currents of the north, which once manifestly swept over these elevations.
