RECENT EXPLORATIONS.--While M. Vouga was one day making excavations near a group of piles, which he considered to have been supports for a bridge, he came upon the foundations of a wooden house, and in the course of clearing it out he made the important discovery that it had been situated on the brink of a deep channel, which had subsequently become filled up with sand and gravel. The most natural explanation was that this channel was an ancient river-bed which, when the house was constructed, formed the outlet of the lake. With this idea paramount in his mind, Vouga determined to trace out its direction and bearings. About 20 yards farther up--_i.e._ in the direction of the lake--he came upon the remains of a second wooden house, with its foundation beams still _in situ_, and two of its containing walls (which had evidently fallen over) lying one over the other. Here the bank of the channel formed a steep descent of 10 feet deep. The floor of this structure was formed of two square-cut beams, each over 16 feet in length and 8 inches in thickness, having a series of closely-set mortised holes for transverse beams. Its breadth was 9 feet 2 inches, and it lay 2½ feet below the surface, and about 7 feet higher than the bottom of the river. The two sides of the building were formed of three beams corresponding in length with that of the flooring, and about 2½ feet apart, and having transverse mountings and a trellis-work of branches. One of these had apparently fallen into the river, as its end reached nearly to the bottom of the channel. Pursuing his investigations still in the direction of the lake, he came upon the remains of a third building, near which were the piles of a second bridge. The space between the two bridges was about 100 yards, and, judging from the position of the piles, this bridge was directed to the same point as the former--probably La Sauge, at the opposite corner of the lake. These bridges were supported on a succession of parallel rows of oak piles 4 to 6 inches in diameter, and placed at intervals of 3 to 20 yards; and each row contained five or six piles, from half a foot to 3 feet apart. About 50 yards above the second bridge a fourth dwelling was encountered, but it appeared to have been already pillaged of its contents. Near this our explorer proceeded to clear a portion of the bed of the river, and lying in the mud and gravel at a depth of 10 feet from the original surface he found a large quantity of antiquities--swords, lances, axes, chains, razors, various wooden implements, fragments of a large vase, the entire wheel and other parts of a chariot, together with the bones of men, horses, and oxen. A fifth building was subsequently discovered between the third and fourth, so that we have here the evidence of a row of five houses situated along the right bank of the ancient river, and all within a distance of 200 yards.
