It had been the winter of 1835-6 that the ship, Alert, in her voyage for hides on the remote and almost unknown coast of California, floated into the vast solitude of the bay of San Francisco. All around was the stillness of nature. One vessel, a Russian, lay at anchor there, but during our whole stay not a sail came or went. Our trade was with remote missions, which sent hides to us in launches manned by their Indians... Over a region far beyond our sight there was no other human habitations, expect that an enterprising Yankee, years in advance of his time, had put up, on the rising ground above the landing, a shanty of rough boards, where he carried on a very small retail trade between the hide ships and the Indians. On the evening of Saturday, the thirteenth of August, 1859 (I again sailed into) the entrance to San Francisco, (now) the great center of worldwide commerce.

So long as physiologists continued to believe that man had not existed on the earth above six thousand years, they might, with good reason, withhold their assent from the doctrine of a unity of origin of so many distinct races; but the difficulty becomes less and less, exactly in proportion as we enlarge our ideas of the lapse of time during which different communities may have spread slowly, and become isolated, each exposed for ages to a peculiar set of conditions, whether of temperature, or food, or danger, or ways of living.
Charles Lyell
