boat, I should suppose, could ever proceed with safety, however deep might be the water. That we had got a passable channel to the left, I was fully satisfied on perceiving the intersection of the first Chicasaw Bluffs or hills, all the high lands of the Mississippi being uniformly washed at their base by a deep and rapid current. Here we landed for a few moments, to survey those hills, the only ones we had seen since leaving the Iron banks. The ascent was steep, and the elevation between 2 and 300 feet above the level of the river. These banks appeared to consist of a stratified, ferruginous, and bluish sandy clay, probably a disintegrated sandstone, which it perfectly resembled to the eye, though altogether friable to the touch. In some places, lower down the river, we observed masses of ferruginous conglomerate blackened by the atmosphere, the pebbles chiefly hornstone, and some of them quartz. The debris of which this conglomerate consists is entirely adventitious, or unconnected with the existing rocks, which form the basis of this ancient deposit.
At this place, we saw the first cabin since our departure from the Little Prairie. On approaching the 34th island from the mouth of the Ohio, which presents itself rounding, and nearly in the middle of the river, we had at first determined to take the left-hand side, set down by the Navigator as the channel, but finding ourselves to float very slowly, we rowed a little, and then submitted to the current. It was soon {51} observable, that we drifted towards the right-hand channel, though much the narrowest, and my companion advised that we should keep the left, especially as it was the nearest, and as the wind accompanied by rain blew strongly up the river.
