A similar inference might not unfairly be drawn with regard to those numerous discoveries of proofs of the existence of ruder man, at still earlier periods. The flint-headed arrow of the North American Indian, and the stone hatchet of the Australian black-fellow exist to the present day; and but a century or two back, would have been the sole representatives of the constructive intelligence of humanity over nearly one half the inhabited surface of the world. No philosopher, with these alone to reason on, could have imagined the settled existence, busy industry, and superior intelligence which animated the other half; and a parallel suggestive argument may be supported by the discovery of human relics, implements, and artistic delineations such as those of the hairy mammoth or the cave-bear. These may possibly be the traces of an outlying savage who co-existed with a far more highly-organized people elsewhere,[88] just as at the present day the Esquimaux, who are by some geologists considered as the descendants of Palæolithic man, co-exist with ourselves. They, like their reputed ancestors, have great ability in carving on bone, &c.; and as an example of their capacity not only to conceive in their own minds a correct notion of the relative bearings of localities, but also to impart the idea lucidly to others, I annex a wood-cut of a chart drawn by them, impromptu, at the request of Sir J. Ross, who, inferentially, vouches for its accuracy. [Illustration: FIG. 29. (_From Sir John Ross' Second Voyage to the Arctic Regions._)] There is but a little step between carving the figure of a mammoth or horse, and using them as symbols. Multiply them, and you have the early hieroglyphic written language of the Chinese and Egyptians. It is not an unfair presumption that at no great distance, in time or space, either some generations later among his own descendants, or so many nations' distance among his coevals, the initiative faculty of the Palæolithic savage was usefully applied to the communication of ideas, just as at a much later date the Kououen symbolic language was developed or made use of among the early Chinese.[89] Such is, necessarily, the first stage of any written language, and it may, as I think, perhaps have occurred, been developed into higher stages, culminated, and perished at many successive epochs during man's existence, presuming it to have been so extended as the progress of geology tends to affirm. May not the meandering of the tide of civilization westward during the last three thousand years, bearing on its crest fortune and empire, and leaving in its hollow decay and oblivion, possibly be the sequel of many successive waves which have preceded it in the past, rising, some higher, some lower, as waves will.
