The Quaker Colonies: A Chronicle of the Proprietors of the Delaware
(1919)
“ The immense quantities of wild fowl and animal and bird life along the shores astonished them; but what most aroused their cupidity was the enormous supply of furs, especially beaver and otter, that could be obtained from the Indians. Furs became their great, in fact, their only interest in the Delaware. They established forts, one near Cape Henlopen at the mouth of the river, calling it Fort Oplandt, and another far up the river on the Jersey side at the mouth of Timber Creek, nearly opposite the present site of Philadelphia, and this they called Fort Nassau. ”
