my inclinations for the sea were by this time worne out, or i might now have gratify'd them. but, having a trade, and supposing myself a pretty good workman, i offer'd my service to the printer in the place, old mr. william bradford, who had been the first printer in pennsylvania, but removed from thence upon the quarrel of george keith. he could give me no employment, having little to do, and enough already; but says he, "my son at philadelphia has lately lost his principal hand, aquila rose, by death; if you go thither, i believe he may employ you." philadelphia was a hundred miles further; i set out, however, in a boat for amboy, leaving my chest and things to follow me round by sea.
