Now the traces of the existence of men in North America during the Glacial epoch have in recent years been discovered in abundance, as for example, the palæolithic quartzite implements found in the drift near the city of St. Paul, which date from toward the close of the Glacial epoch[6]; the fragment of a human jaw found in the red clay deposited in Minnesota during an earlier part of that epoch;[7] the noble collection of palæoliths found by Dr. C. C. Abbott in the Trenton gravels in New Jersey; and the more recent discoveries of Dr. Metz and Mr. H. T. Cresson.
