this new paſſage gave vent. There are ſtill remaining, and daily diſcovered, innumerable inſtances of ſuch a deluge on both ſides of the river, after it paſſed the hills above the falls of Trenton, and reached the champaign.

The ſpot on which Philadelphia ſtands evidently appears to be made ground. The different ſtrata through which they paſs in digging to water, the acorns, leaves, and ſometimes branches, which are found about twenty feet below the ſurface, all ſeem to demonſtrate this.
