The Indian trails of New York were first obliterated by wagon-roads or metaled turnpikes, and then covered by iron rails and wooden ties. The flanged iron wheels have taken the place of the moccasin, as loco-motor and freight-carrier; but in Johnson’s time the valleys, passes, and portages or “carries” were all definitely marked, and generally easily visible, on account of the long tramping of inturned feet. There are places to-day on the flinty rock polished by long attrition of deer-leather soles; and wherever the natural features of the landscape point to the probable saving of linear space, there skilled search usually reveals the old trail. One of the first proofs of the genius of Johnson and the entrance in his mind of continental ideas was his thorough study of the natural highways, trails, and watercourses of the Iroquois empire, and the times and methods of their punctual migrations. He soon found that while late autumn, winter, and spring was their season for trapping and shooting their game, June, July, and August formed the period when the peltries were brought in for sale. In early autumn they went fishing, or their travelling-parties were on peaceful errands, such as attending those council-fires which filled all the atmosphere with blue haze. As a rule, the Indians avoided the mountains, and dwelt in the valleys and well-watered regions, where fish and game for food, osiers and wood fibres for their baskets, clay for their rude pottery abounded, and where pebbles of every degree of hardness were at hand, to be split, clipped, drilled, grooved, or polished for their implements of war, ceremony, and religion. In savage life, vast areas of the earth’s surface are necessary for his hunting and nomad habits. Agriculture and civilization, which mean the tilling and dressing of the earth, enable a tribe to make a few acres of fertile soil suffice, where one lone hunter could scarcely exist. The constant trenching upon the land of the wild hunter and fisherman, by the farmer and manufacturer, who utilize the forces of Nature, and the resistance of the savage to this process, make the story of the “Indian question.” Apart from the pretext of religion, equally common to all, the main object of French, Dutch, and English traders was fur, as that of the New England coast men was fish. The tremendous demand of Europe and China kept the prices of peltries high, and it was in this line of commercial effort that fortunes were most quickly made, most of the early profits being reckoned at twenty times the amount of outlay. Until 1630 a strict monopoly of two trading-companies shut out all interlopers from the Indian country.
