THE ANTIQUITY OF THE HUMAN RACE.
So much for antique monuments and their teachings—alone and in connection with history and tradition—respecting the peoples to whom they owe their existence. Another and not less important value they have, in connection with geology and paleontology, in what they tell us about the age of the human race on the earth. Biblical tradition, as interpreted in former times, asserts the earth and its inhabitants to be about six thousand years old. Geology has enforced a new interpretation, which, so far as the age of the earth is concerned, is accepted by all latter-day scholars; and geology now lends a helping hand to her sister sciences in their effort to prove, what is not yet universally accepted as truth, that man's antiquity far exceeds the limit which scripture is thought to establish.
Throughout the successive geologic strata of earthy matter that overlie the solid rocky foundations below, traces of man's presence are found. It is in deposits of peat and alluvium that these traces are most clearly defined and with greatest facility studied. The extremely slow accumulation of these deposits and the great depth at which human remains appear, impress the mind of the observer with a vivid idea of their antiquity. Calculations based on the known rate of increase for a definite period fix the age of the lowest relics at from six thousand to one hundred thousand years according to the locality. But geology tells yet no definite tale in years, her chronology being on a grander scale, and these calculations are to scientific men the weakest proofs of man's antiquity. As we penetrate, however, this superficial geologic formation, we find in the upper layers weapons and implements of iron; then, at a greater depth, of bronze; and lowest of all stone is the only durable material employed. In all parts of the world, so far as explorations have been made, this order of the ages, stone, bronze, iron, is observed; although they were certainly not contemporaneous in all regions. With the products of human skill, in its varying stages of development, are mingled the fossil trees and plants of different species which flourished and became locally extinct as the centuries passed away. So animal remains, no less abundant than the others, indicate successive changes in the fauna and its relations to human life, the animals pursued at different epochs for food, the introduction of domestic animals, and the transition from the chase to agriculture as a means of subsistence.
From a study of all these various relics of the past—human, animal, and vegetable—in connection with geologic changes, the student seeks to estimate approximately the date at which man first appeared upon the earth. He observes the slow accumulation of surface deposits and speculates on the time requisite to bury the works of man hundreds of feet deep in dilluvium. He studies savagism in its different phases as portrayed in a previous volume; notes how tenaciously the primitive man clings to old customs, how averse he is to change and improvement; and then reflects upon the centuries that would probably suffice for beings only a little above the beast to pass successively from the use of the shapeless stone and club to the polished stone spear and arrow and knife, to the partial displacement of stone by the fragment of crude metal, to the smelting of the less refractory ores and the mixture of metals to form bronze, and to a final triumph in the use of iron. He reflects farther that all this slow process of development precedes in nearly every part of the world the historic period; that its relics are found in the alluvial plains of the Nile, buried far below the monuments of Egyptian civilization, a civilization, moreover, which dates back at least two thousand years before Christ. Searching the peat-beds of Denmark, he brings to light fossil Scotch firs in the lower strata mingled with relics of the stone age; oak-trees above with implements of bronze; and beech-trunks in the upper deposits, corresponding with the iron age and also with the present forest-growth of the country. He tries to fix upon a period of years adequate to effect two complete changes in Danish forest-trees, bringing to his aid the fact that about the Christian era the Romans found that country covered as now with a luxurious growth of beech, and that consequently eighteen hundred years have wrought no change. Having thus established in his mind the epoch to which he must be carried by the relics of the alluvial deposits, he remarks that during all this period climate has not essentially changed, for the animal remains thus far discovered are all of species still existing in the same climatic zone.
But at the same time he finds in southern Europe abundant remains of polar animals which could only have lived when the everlasting snow and ice of a frigid clime covered the surface of those now sunny lands. Still finding rude stone implements, the work of human hands, mingled with these polar skeletons, he adds to the result of previous computations the time deemed necessary for so essential a climatic transformation, and, finally, he is driven to make still another addition, when he learns that in geologic strata much older than any yet considered, the bones and works of man have been discovered in several apparently well-authenticated instances lying side by side with the bones of mastodons and other ancient species which have long since disappeared from the face of the earth. With the innumerable data of which the foregoing is only an outline before him, the student of man's antiquity is left to decide for himself whether or not he can satisfactorily compress within the term of sixty centuries all the successive periods of man's development.
In our examination of relics in the thinly peopled Pacific States we shall find comparatively few works of human hands bearing directly on this branch of archæology; yet in the north-west regions, newest to modern civilization, the Californian miner's deep-sunk shafts have brought to light implements and fossils of great antiquity and interest to the scientific world.
AMERICAN RELICS AND HIEROGLYPHICS.
In America many years must elapse before explorations equaling in extent and thoroughness those already made in the old world can be hoped for. The ruins from whose examination the grandest results are to be anticipated lie in a hot malarious climate within the tropics, enveloped in a dense thicket of exuberant vegetation, presenting an almost impenetrable barrier to an exploration by foreigners of monuments in which the natives as a rule take no interest. It must be admitted, however, that even the most exhaustive examination of our relics cannot be expected to yield results as definite and satisfactory as those reached in the eastern continent. We have practically no written record, and our monuments must tell the tale of the distant past unaided.
Our hieroglyphic inscriptions are comparatively few and brief, and those found on the stones of the more ancient class of ruins as yet convey no meaning. By reason of the absence of a contemporary written language, the difficulties in the way of their interpretation are clearly much greater than those so brilliantly overcome in Assyria and Egypt. Only one systematic attempt has yet been made to decipher their signification, and that has thus far proved a signal failure; it is believed almost universally that future efforts will be equally unsuccessful, and that our annals as written in stone will forever remain wrapped in darkness. Yet not only was the interpretation of the cuneiform inscriptions long deemed an impossibility, but the very theory that any meaning was hidden in that complicated arrangement of wedges was pronounced absurd by many wise antiquaries. Let not therefore our New World task be abandoned in despair till the list of failures shall be swollen from one to seventy times seven.
It is believed that the antiquary's zeal for all coming time will be brought to bear on no other objects than those which now claim our attention and search; that is, although new monuments will be brought to light from their present hiding-places, no additions will be made to their actual number. With the invention of printing and the consequent wide diffusion of national annals, the era of unwritten history ceased, and with it all future necessity of searching tangled forest and desert plain for monumental records of the present civilization. That the key of our written history can ever be lost, our civilization blotted out, ruined structures and vague traditions called anew into requisition for historic use, we believe impossible. Yet who can tell; for so doubtless thought the learned men and high-priests of Palenque, when with imposing pageant and sacrificial invocation to the gods in the presence of the assembled populace, the inscribed tablets had been set up in the niches of the temple; and proudly exclaimed the orator of the day, as the last tablet settled into its place, "Great are our gods, and goodly the inheritance they have bequeathed to their chosen people. Mighty is Votan, world-wide the fame of his empire, the great Xibalba; and the annals and the glory thereof shall endure through all the coming ages; for are they not here imperishably inscribed in characters of everlasting stone that all may read and wonder?"
