  Just north of the "Skoolekil" River is the "Wicoco" Plantation which was the future site of Philadelphia. William Penn selected this site because "It seemed appointed for a town, because of its coves, docks, springs, and lofty land!" [from John F. Watson. Annals of Philadelphia and Pennsylvania in the Olden Times. Philadelphia: Whiting & Thomas, 1856. Vol. 1. p. 55]
