the character of the mounds spoken of, it is believed that the probabilities strongly preponderate in favour of their artificial origin, even admitting their _perfect_ analogy to those "from whose sides gush the springs." But more anon. _St. Louis._ XII "Where, through the long-drawn aisle and fretted vault, The pealing anthem swells the note of praise." GRAY. "Some men have been Who loved the church so well, and gave so largely to't, They thought it should have canopied their bones Till doomsday." There are few more delightful views in the vicinity of St. Louis of a fine evening than that commanded by the summit of the "Big Mound," of which I have spoken, in the northern suburbs of the city. Far away from the north comes the Mississippi, sweeping on in a broad, smooth sheet, skirted by woodlands; and the rushing of its waters along the ragged rocks of the shores below is fancied faintly to reach the ear. Nearly in the middle of the stream are stretched out the long, low, sandy shores of "Blood Island," a spot notorious in the annals of duelling. Upon the Illinois shore beyond it is contemplated erecting a pier, for the purpose of throwing the full volume of the current upon the western shore, and thus preserving a channel of deep water along the landing of the city. Within a few years past an extensive sand-bar has accumulated opposite the southern section of the city, which threatens, unless removed, greatly to obstruct, if not to destroy, the harbour. To remedy this, an appropriation {135} has been made by Congress, surveys have been taken, measures devised and their execution commenced.[112] Upon the river-bank opposite the island stands the "Floating Dry Dock," an ingenious contrivance, the invention of a gentleman of St. Louis, and owned by a company of patentees.[113] It consists of an indefinite number of floats, which may be increased or diminished at pleasure, each of them fourteen feet in breadth, and about four times that length, connected laterally together. After being sunk and suspended at the necessary depth in the water, the boat to be repaired is placed upon them, and they rise till her hull is completely exposed.
