In one part of his journey, the road extended almost wholly through pine-forests, and was very lonely. Night came on before he reached the end of it; and, as commonly happens with travellers in this part of the world, he soon lost his way. A light, however, seen through the trees, seemed to indicate that a house was not far distant. His servant eagerly rode up to it, but the poor fellow's consternation was great indeed when he observed it moving from him, presently coming back, and then, with swiftness, departing into the woods. Mr. Weld was himself at a loss to account for this singular appearance, till, after having proceeded a little further, he observed the same sort of light in many other places; and, dismounting from his horse to examine a bush, where one of these sparks appeared to have fallen, he found that it proceeded from a fire-fly. In the present instance Mr. Weld was much surprised; but, as the summer advanced, these flies appeared every night. After a light shower in the afternoon, this gentleman says he has seen the woods sparkling with them in every direction. The light is emitted from the tail, and the animal has the power of emitting it or not at pleasure. After wandering about till near eleven o'clock, he came at last to a house, where he obtained information respecting the road: and, about midnight, he arrived at a miserable tavern. During the next day's ride he observed a great number of snakes, which were now beginning to come forth from their holes. The _South-west Mountains_ run nearly parallel to the _Blue Ridge_, and are the first that are seen in Virginia, on going up the country, from the sea-coast. They are not lofty, and ought indeed rather to be called hills than mountains. These mountains are not seen till the traveller comes within a few miles of them; and the ascent is so gradual, that he reaches their top almost without perceiving it. The soil is here a deep clay, particularly well suited to the culture of grain and clover, and it produces abundant crops. The salubrity of the climate, in this part of Virginia, is equal also to that of any part of the United States; and the inhabitants have, in consequence, a healthy and ruddy appearance, totally different from that of the residents in the low country. In these mountains live several gentlemen of large property, who farm their own land. Among the number was Mr. Jefferson, the vice-president of the United States. His house was about three miles from Charlottesville, and was most singularly situated, being built on the top of a small mountain, the apex of which had been cut off. At this time it was in an unfinished state; but, if carried on, according to a plan which had been laid down, it promised to be one of the most elegant private habitations in America. Several attempts have been made in this neighbourhood, to bring the manufacture of wine to perfection; none of them, however, have succeeded to the wish of the parties concerned in it.
