Archaeology at the University of Pennsylvania.

Many important Archaeological discoveries have recently been made by the University of Pennsylvania exploring parties under the direction of Mr. H. C. Mercer. Explorations have been carried on in many places in the South and West, and a valuable collection of fossils has been unearthed.

The investigating party first explored the chalk bluffs of the San Diego River, Texas, where they found mammoth tusks and bones together with flints and axes. They had no proof, however, that man and the mammoth were here contemporaneous, because in many places remains of the Indians are found mingled with the traces of an earlier age. In these instances, investigation has shown that the confusion was caused in subsequent years. But discoveries in the Look-out and Nickajack caves near Knoxville, Tenn., furnish indisputable evidence that man lived there at the same time with the animals whose bones were found, such as deer, tortoise, elk, rabbit and many others. It is probable that the human beings who lived there had killed those animals for food, since the bones that were scattered about the fire-places were rarely gnawed by animals. Another important discovery was that of the extinct peccary, which has been found also in Hartman's cave, and of teeth of the tapir. The nature of the human remains and the fact that they are found only in one layer, prove that the Indians lived in the cave, and that they had no predecessors in these regions.
