Even in our less attractive latitudes and longitudes, a more auspicious and healthy tone has been given to the spirit of investigation. A voice from one of our western mounds (which has been alluded to) promises to restore the reading of an inscription in one of the earliest alphabets of the world. Sculptures have recently been disclosed in some of the minor mounds of the West, which are executed in a polished style of art, and strongly connect the Mexican and American tribes. The figures of animals and birds, taken from some barrows in the Scioto valley, are executed in a manner quite equal to anything of the kind found in Mexico or Peru. Mythological evidence is also assuming more distinctive grounds. An imitative mound of a gigantic serpent swallowing an egg, has been discovered in one of the forest counties of Ohio, while I have been engaged in penning these remarks. The discovery of this curious structure, which is coiled for the distance of a quarter of a mile around a hill, transfers to our soil a striking and characteristic portion of oriental mythology. Scarcely a season passes, indeed, which does not add, by the extension of our settlements, or the direct agency of exploration, to the number of monumental evidences of antique occupancy. But were these, indeed, wanting--were there no mounds or pyramids of sepulture or sacrifice--no remains of art--no inscriptive testimonies to speak of by-gone centuries--we have before us one of the most interesting of all monumental proofs in the lost and enigmatical race, who yet rove the boundless forests of the West and South. Whether there be evidences to separate the eras and nations of the most ancient inhabitants from those whose descendants yet remain, is one of the very points at issue. If the descendants of the mound and temple builders yet exist, the traditions of the era have passed from them in the process of their declension. But whoever the builders were, and whether their blood still flows in the existing race or not, they clung, like this race, so firmly to their ancient mythology and religion as to impress it indelibly on the features of their architecture, and in almost every work or labor which they attempted.
