 a well-known scientific journal. In the meantime, it may be sufficient to say, it is now ascertained, that the waters of Erie, and other great lakes, formerly flowed southward into the valley of the Ohio; and that a cataract, more tremendous than the falls of Niagara, raged among the rocks of Silver Creek hills.

In the neighbourhood of Salt River and Green River, in Kentucky, there are extensive tracks of barren wastes. Small hazel bushes from two to three feet in height abound in these; and the quantity of nuts produced exceeds any thing of the kind which I have ever seen. The soil of these wastes seems to be very similar to that of the adjoining woods; and on account of the trees diminishing gradually in size, from the forest toward the waste, it is sometimes impossible to discover a line where the one stops and the other begins. This, together with the fact told by an old settler, that some small saplings which stood on his farm twenty years ago, are now become tall trees, leads me to adopt the opinion entertained by some, that the wastes or barrens owe their characteristic form to the Indians, who set fire to dried grass and other vegetables with the design of facilitating their hunting.

Salt River is between 100 and 150 yards wide where it unites with the Ohio, and is navigable for about sixty miles. The name is derived from salt springs in its vicinity that are now wrought. Opposite to the mouth of this river, on the north {259} bank of the Ohio, stands a sycamore tree of stupendous size, which is hollow within. I measured the cavity, and found one diameter to be twenty-one feet, and the other twenty feet. In one side of it, a hole is cut sufficiently large to admit a man on horseback. It was probably a sycamore considerably less than this that is noticed in the Pittsburg Navigator,
