In fact, ethnography and archæology should go hand in hand; and the principal object I have in view in giving publicity to the following too desultory remarks, is to impress on travellers and others who are favorably situated for making observations, the importance of preserving every relic, organic or artificial, that can throw any light on the past and present condition of our native tribes. Objects of this nature have been too often thrown aside as valueless; or kept as mere curiosities, until they were finally lost or become so defaced or broken as to be useless. To render such relics available to science and art, their history and characteristics should be recorded in the periodicals of the day; by which means we shall eventually possess an accumulated mass of facts that will be all-important to future generalization. I grant that this course has been ably pursued by many intelligent writers, and the American Journal of Science is a fruitful depository of such observations.[4-*] With every acknowledgment to these praiseworthy efforts, let us urge their active continuance. Time and the progress of civilization are daily effacing the vestiges of our aboriginal race; and whatever can be done to rescue these vestiges from oblivion, must be done quickly. We call attention in the first place, to two skulls from a mound about three miles from the mouth of Huron river, Ohio. They were obtained by Mr. Charles W. Atwater, and forwarded to Mr. B. Silliman, Jr., through whose kindness they have been placed in my hands. These remains possess the greater interest, because the many articles found with them present no trace of European art; thus confirming the opinion expressed in Mr. Atwater's letter:--"There are a great many mounds in the township of Huron," he observes, "all which appear to have been built a long time previous to the intercourse between the Indians and the white men. I have opened a number of these mounds, and have not discovered any articles manufactured by the latter. A piece of copper from a small mound is the only metal I have yet found." The stone utensils obtained by Mr. Atwater in the present instance, were, as usual, arrow heads, axes, knives for skinning deer, sling-stones, and two spheroidal stones on which I shall offer some remarks in another place. The materials of which these articles are formed, are jasper, quartz, granite stained by copper, and clay slate, all showing that peculiar time-worn polish which such substances acquire by long inhumation.
