Natcheekin is a very inconsiderable _ostrog_, having only one log-house, the residence of the _Toion_; five _balagans_, and one _jourt_. We were received here with the same formalities, and in the same hospitable manner, as at Karatchin; and in the afternoon we went to visit a remarkable hot spring, which is near this village. We saw, at some distance, the steam rising from it, as from a boiling caldron; and as we approached, perceived the air had a strong sulphureous smell. The main spring forms a bason of about three feet in diameter; besides which, there are a number of lesser springs, of the same degree of heat, in the adjacent ground; so that the whole spot, to the extent of near an acre, was so hot, that we could not stand two minutes in the same place. The water flowing from these springs is collected in a small bathing pond, and afterward forms a little rivulet; which, at the distance of about an hundred and fifty yards, falls into the river. The bath, they told us, had wrought great cures in several disorders, such as rheumatisms, swelled and contracted joints, and scorbutic ulcers. In the bathing-place the thermometer stood at 100°, or blood heat; but in the spring, after being immersed two minutes, it was 1° above boiling spirits. The thermometer in the air, at this time, was 34°; in the river 40°; and in the _Toion’s_ house 64°. The ground where these springs break out, is on a gentle ascent; behind which there is a green hill of a moderate size. I am sorry I was not sufficiently skilled in botany to examine the plants, which seemed to thrive here with great luxuriance; the wild garlic, indeed, forced itself on our notice, and was at this time springing up very vigorously.
