"Till twilight came, and lovers walked and wooed
In a forgotten language; and old tunes,
From instruments of unremembered forms,
Gave the soft winds a voice."
There is evidence which goes to prove that the Mound Builders had relations with the people of a semi-tropical region in the direction of Atlantis. Among their sculptures, in Ohio, we find accurate representations of the lamantine, manatee, or sea-cow—found to-day on the shores of Florida, Brazil, and Central America—and of the toucan, a tropical and almost exclusively South American bird. Sea-shells from the Gulf, pearls from the Atlantic, and obsidian from Mexico, have also been found side by side in their mounds.
The antiquity of their works is now generally conceded. "From the ruins of Nineveh and Babylon," says Mr. Gliddon, " we have bones of at least two thousand five hundred years old; from the pyramids and the catacombs of Egypt both mummied and unmummied crania have been taken, of still higher antiquity, in perfect preservation; nevertheless, the skeletons deposited in our Indian mounds, from the Lakes to the Gulf, are crumbling into dust through age alone."
All the evidence points to the conclusion that civilized or semi-civilized man has dwelt on the western continent from a vast antiquity. Maize, tobacco, quinoa, and the mandico plants have been cultivated so long that their wild originals have quite disappeared.
"The only species of palm cultivated by the South American Indians, that known as the Gulielma speciosa, has lost through that culture its original nut-like seed, and is dependent on the hands of its cultivators for its life. Alluding to the above-named plants Dr. Brinton ("Myths of the New World," p. 37) remarks, 'Several are sure to perish unless fostered by human care. What numberless ages does this suggest? How many centuries elapsed ere man thought of cultivating Indian corn? How many more ere it had spread over nearly a hundred degrees of latitude and lost all resemblance to its original form?'
