This first room holds what is regarded by the curator as the most important series of objects ever brought together illustrative of that ancient people who built the mounds and the singular stone graves of the southern and central portions of the United States. The contents of each mound and grave are arranged by themselves, so that as one passes from case to case a picture of the human life of the past is presented as nearly perfect as can be constructed out of that part of the handiwork of the people which has escaped decay. Here can be seen and studied the many singular results of the potter's art, simple and complex in form and varied in style of ornament; carvings in stone, shell, and bone; implements and ornaments of stone, shell, bone, mica, clay, copper, and other substances; fragments of cloth and twine twisted from vegetable fibres, which have been preserved through charring. One case in this room is devoted to a collection of objects from caves in Kentucky and Tennessee, and contains many interesting fabrics, including a large piece of cloth woven from bark-fibre, shoes formed by braiding leaves of the cat-tail rush, and many other things kept for us in the dry air of the caves through uncounted centuries. In the gallery are grouped several collections from Mexico and Central America, which are especially rich in pottery.
In the room, on the second floor, over this one are stored the most ancient--most primitive--evidences of man's presence yet discovered in the Atlantic States,--evidences in the shape not only of chipped stones of his fashioning, but relics of his very frame, which incontestably extend the period of human occupation along our Atlantic coast back at least to the glacial era. I refer to the palæolithic remains exhumed by Dr. C. C. Abbott from the terraces of river-drift in the valley of the Delaware at Trenton, New Jersey. These deposits of pebbles and sand owe their origin to the continental glacier, whose front reached in solid mass almost to that locality; through them was worn the bed of the present river, and whatever is contained in their undisturbed mass can belong to no more recent date than the later days of the glacial period.
