ATLANTIS: THE ANTEDILUVIAN WORLD.

and during that time no similar domestication of a wild animal has been made. This fact speaks volumes as to the vast periods of time during which man must have lived in a civilized state to effect the domestication of so many and such useful animals.

And when we turn from the fauna to the flora, we find the same state of things.

An examination of the fossil beds of Switzerland of the Miocene Age reveals the remains of more than eight hundred different species of flower-bearing plants, besides mosses, ferns, etc. The total number of fossil plants catalogued from those beds, cryptogamous as well as phænogamous, is upward of three thousand. The majority of these species have migrated to America. There were others that passed into Asia, Africa, and even to Australia. The American types are, however, in the largest proportion. The analogues of the flora of the Miocene Age of Europe now grow in the forests of Virginia, North and South Carolina, and Florida; they include such familiar examples as magnolias, tulip-trees, evergreen oaks, maples, plane-trees, robinas, sequoias, etc. It would seem to be impossible that these trees could have migrated from Switzerland to America unless there was unbroken land communication between the two continents.

It is a still more remarkable fact that a comparison of the flora of the Old World and New goes to show that not only was there communication by land, over which the plants of one continent could extend to another, but that man must have existed, and have helped this transmigration, in the case of certain plants that were incapable of making the journey unaided.

Otto Kuntze, a distinguished German botanist, who has spent many years in the tropics, announces his conclusion that "In America and in Asia the principal domesticated tropical plants are represented by the same species." He instances the Manihot utilissima, whose roots yield a fine flour; the tarro (Colocasia esculenta), the Spanish or red pepper, the tomato,
