That various tribes have also dwelt in our western valleys, is quite certain; and that our whole country has, at remote periods, been the theatre of strange events, and the residence of peculiar people, cannot admit of doubt. While some of that people were unacquainted with the use of metals, others must have possessed a very good knowledge of them, and withal the mode of working them. A well-finished steel bow, found in one of the western tumuli, and the scoria, evidently the product of forges discovered among the works which have been left by some previous inhabitants of the Ohio valley, are among the proofs of this fact. Hieroglyphical writing, long a desideratum among the remains of the primitive inhabitants of the United States, has also been discovered. Descriptive paintings similar to those executed by the Mexicans, may in like manner have been left by this people, but they would have disappeared, had they been so left, from the effects of time. No stone edifices resembling those of Mexico have however been found among us; no piles of rude masonry, stone fortifications, bridges, viaducts, etc., as at Palenque and other places. There are some traces, if recent accounts be true, of tumuli and walls in this country, which were built in part of burnt bricks, not unlike those with which the great pyramid of Chollula was built; yet there are none in the same style and magnificence. Enough, however has been noticed, among the ancient arts of this country, to satisfy us that our primitive inhabitants may have been among the builders of that stupendous structure. The same form may now be noticed in a tumulus near Cincinnati. Others have been destroyed, which had the same pyramidal form, with regular off-sets. On the tops of these, and particularly those of a large size, it has been conjectured that structures similar to those of Mexico were built. The one ruthlessly destroyed at Circleville, Ohio, affords strong evidences of its having been devoted to the worship of the sun, and to the offering of human sacrifices. But more of this anon. Subsequent remarks will tend to show, when we shall have furnished other particulars of newly-discovered ruins in Central America, how far those of our own country agree with the ancient arts of Mexico. THE ENCAGED BIRD TO HIS MISTRESS. LADY, sweet lady! let me go, To breathe again my native air; Where mountain streams unfetter'd flow, And wild flowers in profusion bear; Where mingled notes of feather'd throng Pour forth their free, harmonious song, In praise to Him who bids them fly, Bound only by the lofty sky: I pine! I pine! to stretch my wings, And feel the sun's enlivening glow-- To join the lay the free-bird sings; Kind lady! let thy prisoner go!
