42 ADAMITES AND PREADAMITES.
their presence has been so recent that their stumps linger in the gulches of the Sierra Nevada; and huge masses remain undissolved in the ice-wells of Vermont, New York and Wisconsin. The truth is we are not so far out of the dust and smoke of antiquity as we had supposed. Antiquity is at our doors. Multitudes of facts might be cited which must tend to convince us that changes are in progress before our eyes, which must accomplish in a few thousand years results as great as those which separate the Stone Folk from us.
But how many years express the interval? This is the point on which it is not safe to be too precise. I can enumerate a dozen of the highest authorities in prehistoric archaeology, who bring the epoch of polished stone down to within four to six thou-sand years of our time; and I could cite historical mention and historical data to show that the Stone Folk were known from a date 4000 or 5000 B. C., when the Iberians found them, down to 3000 or 3500 B. C., when the Iberian Libyans made war on Egypt, and thence down to 2000 B. C., when the Stone Folk were found in Sicily and Peloponnesus.
The Stone Folk had lived somewhere at an earlier epoch. Their Asiatic progenitors were more ancient. If descended from the white man's Adam, he must be removed somewhat further back than we have supposed. If Adam, however, is a divergent twig from the same stock as the Stone Folk, then the Stone Folk may have been in Europe even before our Adam appeared in Asia.
ORIGIN OF MAN.
The recognition of the descent from one stock, of types of structure as diverse as the European and the Australian, prompts at once an inquiry respecting the extent to which divergencies may have been carried. Whether the Negro has descended from the white man's Adam, or the Caucasian from the black man's Adam, there is implied a degree of physical divergence which is very suggestive of reflection. The more we insist on the blood affinity of the races of man, the more we crowd upon attention
