Frederick Jackson Turner,
Rise of the New West, 1819-1829
“ As traveler after traveler passed over the routes of his predecessor in this period, reporting the life by the wayside and in the towns, we can almost see American society unfolding with startling rapidity under our gaze; farms become hamlets, hamlets grow into prosperous cities; the Indian and the forests recede; new stretches of wilderness come into view in the farther west, and we see the irresistible tide of settlement flowing towards the solitudes. ”
