We are merely beginning the enormous labor which is before us; we have yet to discover the methods by which we can analyze fruitfully the facts we already know. But I look forward with the utmost confidence to a rich return from such investigations. The day is coming, and that rapidly, when the pre-historic life of man in both the New and the Old World will be revealed to us in a thousand unexpected details. We have but to turn backward about thirty years to reach a time when the science of pre-historic archæology was unknown, and its early gropings were jeered at as absurdities. Already it has established for itself a position in the first rank of the sciences which have to do with the highest of problems. It has cast a light upon the pathway of the human race from the time that man first deserved his name down to the commencement of recorded history. Its conquests are but beginning. Year by year masses of new facts are brought to knowledge from unexpected quarters, current errors are corrected, and novel methods of exploration devised.
As Americans by adoption, it should be our first interest and duty to study the Americans by race, in both their present and past development. The task is long and the opportunity is fleeting. A century more, and the anthropologist will scarcely find a native of pure blood; the tribes and languages of to-day will have been extinguished or corrupted. Nor will the archæologist be in better case. Every day the progress of civilization, ruthless of the monuments of barbarism, is destroying the feeble vestiges of the ancient race; mounds are levelled, embankments disappear, the stones of temples are built into factories, the holy places desecrated. We have assembled here to aid in recovering something from this wreck of a race and its monuments: let me urge upon you all the need of prompt action and earnest work, inasmuch as the opportunities we enjoy will never again present themselves in such fulness.
There has been much talk in scientific circles lately about Palæoliths, and much misunderstanding about them. Let me try to explain in a few words what they are, what they tell, and what mistakes people make about them.
Since man first appeared on this planet, his history has been a slow progress from the most rudimentary arts up to those which he now possesses. We know this, because in a given locality those remains of his art which are found undisturbed in strata geologically the oldest are always the rudest. The exceptions to this rule are in appearance only, as for instance when a given locality was not occupied by men until they had already acquired considerable knowledge of arts, or when a cultivated nation was overrun by a barbarous one.
