Under date of July 11, 1681, Penn published _Certain Conditions or Concessions to be agreed upon by William Penn, Proprietary and Governor of the Province of Pennsylvania, and those who may become Adventurers and Purchasers in the same Province_. These conditions relate to dividing, planting, and building upon the land, saving mulberry-and oak-trees, and dealing with the Indians. These documents were circulated, and imparted sufficient knowledge of the country and its produce, so that purchasers at once appeared, and Penn went to Bristol to organize there a company called "The Free Society of Traders in Pennsylvania," who purchased twenty thousand acres of land, and prepared to establish various trades in the province. Yet further to mature his plans, and to begin with a fair understanding among all who might be concerned in the enterprise, Penn drew up and submitted a sketch of the frame of government, providing for alterations, with a preamble for liberty of conscience. On the basis of contracts and agreements thus made and mutually ratified, three passenger ships, two from London and one from Bristol, sailed for Pennsylvania in September, 1681. One of them made an expeditious passage; another was frozen up in the Delaware; and the third, driven to the West Indies, was long delayed. They took over some of the ornamental work of a house for the proprietor. The Governor also sent over three commissioners, whose instructions we learn from the original document addressed to them by Penn, dated September 30, 1681. These commissioners were William Crispin, John Bezar, and Nathaniel Allen. Their duty was that of "settling the colony." Penn refers them to his cousin Markham, "now on the spot." He instructs them to take good care of the people; to guard them from extortionate prices for commodities from the earlier inhabitants; to select a site by the river, and there to lay out a town; to have his letter to the Indians read to them in their own tongue; to make them presents from him--adding, "Be grave; they love not to be smiled upon"--and to enter into a league of amity with them. Penn also instructs the commissioners to select a site for his own occupancy, and closes with some good advice in behalf of order and virtue. These commissioners probably did not sail until the latter part of October, as they took with them the letter to the Indians, to which Penn refers. This letter, bearing the date October 18, 1681, is a beautiful expression of feeling on the part of the proprietor. He does not address the Indians as heathen, but as his brethren, the children of the one Father. He announces to them his accession, as far as a royal title could legitimate it, to a government in their country; he distinguishes between himself and those who had ill treated the Indians, and pledges his love and service.
