We feel that we have done but scant justice to this subject, but we assure our readers that this question has been but little studied in this country. Referring all relics of stone to the Indians, our scholars have been slow to recognize traces of an earlier race in America. Our sources of information are as yet but few, and much remains to be done in this field. In Europe as in America, scholars are still hard at work on the Paleolithic Age, and we are to hold ourselves in readiness to modify our opinions, or to reject them entirely and adopt new ones as our knowledge increases. There is one thought that occurs to us. From the combined investigations of both European and American scholars, the Eskimo is seen to be one of the oldest (if not the oldest) races of men now living. They afford a striking illustration of the fact that a race may early reach a limit of culture beyond which, as a race, they can not pass. Should the American discoveries establish the fact that the River Drift tribes are also Eskimos, then we are fairly entitled to consider them the remnant of a people who once held possession of all the globe, but who have been driven to the inhospitable regions of the North by the pressure of later people. What changes have come over the earth since that early time? In the long lapse of years that have gone by newer races, advancing by slow degrees, have at last achieved civilization. The fiat of Omnipotent power could have created the world in a perfected form for the use of man, but instead of so doing, Infinite Wisdom allowed slow-acting causes, working through infinite years, to develop the globe from a nebulous mass. Man could, indeed, have been created a civilized being, but instead of this, his starting-point was certainly very low. He was granted capacities in virtue of which he has risen. We are not to say what the end shall be, but we think it yet far off. Stone Implement. REFERENCES The manuscript of this chapter was submitted to Dr. C. C.

In general, all about Sonora, in the auriferous gravels, are found bones of extinct animals, and, associated with them, many relics of the works of human hands. These are found at various depths down to one hundred feet. (Whitney’s “Auriferous Gravels,” p. 263.)
