“The recently announced discovery by Commander Gorringe, of the United States sloop Gettysburg, of a bank of soundings bearing N. 85 deg. W., and distant 130 miles from Cape St. Vincent, during the last voyage of the vessel across the Atlantic, taken in connection with previous soundings obtained in the same region of the North Atlantic, suggests the probable existence of a submarine ridge or plateau connecting the island of Madeira with the coast of Portugal, and the probable subaerial connection in prehistoric times of that island with the south-western extremity of Europe.” . . . “These soundings reveal the existence of a channel of an average depth of from 2000 to 3000 fathoms, extending in a northeasterly direction from its entrance between Madeira and the Canary Islands toward Cape St. Vincent. . . . Commander Gorringe, when about 150 miles from the Strait of Gibraltar, found that the soundings decreased from 2700 fathoms to 1600 fathoms in the distance of a few miles. The subsequent soundings (five miles apart) gave 900, 500, 400, and 100 fathoms; and eventually a depth of 32 fathoms was obtained, in which the vessel anchored. The bottom was found to consist of live pink coral, and the position of the bank in lat. 36 deg. 29? N., long. 11
deg. 33? W.”
The map on page 51 shows the position of these elevations. They must have been originally islands;— stepping-stones, as it were, between Atlantis and the coast of Europe.
Sir C. Wyville Thomson found that the specimens of the fauna of the coast of Brazil, brought up in his dredging-machine, are similar to those of the western coast of Southern Europe. This is accounted for by the connecting ridges reaching from Europe to South America.
A member of the Challenger staff, in a lecture delivered in London, soon after the termination of the expedition, gave it as his opinion that the great submarine plateau is the remains of “the lost Atlantis.”
CHAPTER VI.
THE TESTIMONY OF THE FLORA AND FAUNA.
Proofs are abundant that there must have been at one time uninterrupted land communication between Europe and America. In the words of a writer upon this subject,
“When the animals and plants of the Old and New World are compared, one cannot but be struck with their identity; all or nearly all belong to the same genera, while many, even of the species, are common to both continents. This is most important in its bearing on our theory, as indicating that they radiated from a common centre after the Glacial Period. . . . The hairy mammoth, woolly-haired rhinoceros, the Irish elk, the musk-ox, the reindeer, the glutton, the lemming, etc., more or less accompanied this flora, and their remains are always found in the post-glacial deposits of Europe as low down as the South of France. In the New World beds of the same age contain similar remains, indicating that they came from a common centre, and were spread out over both continents alike.” (Westminster Review, January, 1872, p. 19.) Recent discoveries in the fossil beds of the Bad Lands of Nebraska prove that the horse originated in America. Professor Marsh, of Yale College, has identified the several preceding forms from which it was developed, rising, in the course of ages, from a creature not larger than a fox until, by successive steps, it developed into the true horse. How did the wild horse pass from America to Europe and Asia if there was not continuous land communication between the two continents? He seems to have existed in Europe in a wild state prior to his domestication by man.
The fossil remains of the camel are found in India, Africa, South America, and in Kansas. The existing alpacas and llamas of South America are but varieties of the camel family.
The cave bear, whose remains are found associated with the hones of the mammoth and the bones and works of man in the caves of Europe, was identical with the grizzly bear of our Rocky Mountains. The musk-ox, whose relics are found in the same deposits, now roams the wilds of Arctic America. The glutton of Northern Europe, in the Stone Age, is identical with the wolverine of the United States. According to Rutimeyer, the ancient bison (Bos priscus) of Europe was identical with the existing American buffalo. “Every stage between the ancient cave bison and the European aurochs can be traced.” The Norway elk, now nearly extinct, is identical with the American moose. The Cervus Americanus found in Kentucky was as large as the Irish elk, which it greatly resembled. The lagomys, or tailless hare, of the European eaves, is now found in the colder regions of North America. The reindeer, which once occupied Europe as far down as France, was the same as the reindeer of America. Remains of the cave lion of Europe (Felix speloae), a larger beast than the largest of the existing species, have been found at Natchez, Mississippi. The European cave wolf was identical with the American wolf.
Cattle were domesticated among the people of Switzerland during the earliest part of the Stone Period (Darwin’s “Animals Under Domestication,” vol. i., p. 103), that is to say, before the Bronze Age and the Age of Iron. Even at that remote period they had already, by long-continued selection, been developed out of wild forms akin to the American buffalo. M. Gervais (“Hist. Nat. des Mammifores,” vol. xi., p.
191) concludes that the wild race from which our domestic sheep was derived is now extinct. The remains of domestic sheep are found in the debris of the Swiss lake-dwellings during the Stone Age. The domestic horse, ass, lion, and goat also date back to a like great antiquity. We have historical records 7000 years old, and during that time no similar domestication of a wild animal has been made. This fact speaks volumes as to the vast period, 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 phaenogamous, 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, the bamboo, the guava, the mango-fruit, and especially the banana. He denies that the American origin of tobacco, maize, and the cocoa-nut is proved. He refers to the Paritium tiliaceum, a malvaceous plant, hardly noticed by Europeans, but very highly prized by the natives of the tropics, and cultivated everywhere in the East and West Indies; it supplies to the natives of these regions so far apart their ropes and cordage. It is always seedless in a cultivated state. It existed in America before the arrival of Columbus.
