But the hunter was not only thrilled with the passion of the chase and of discovery; he was intent also upon collecting the furs and skins of wild animals for lucrative barter and sale in the centers of trade. He was quick to make "tomahawk claims" and to assert "corn rights" as he spied out the rich virgin land for future location and cultivation. Free land and no taxes appealed to the backwoodsman, tired of paying quit-rents to the agents of wealthy lords across the sea. Thus the settler speedily followed in the hunter's wake. In his wake also went many rude and lawless characters of the border, horse thieves and criminals of different sorts, who sought to hide their delinquencies in the merciful liberality of the wilderness. For the most part, however, it was the salutary instinct of the home-builder--the man with the ax, who made a little clearing in the forest and built there a rude cabin that he bravely defended at all risks against continued assaults--which, in defiance of every restraint, irresistibly thrust westward the thin and jagged line of the frontier. The ax and the surveyor's chain, along with the rifle and the hunting-knife, constituted the armorial bearings of the pioneer. With individual as with corporation, with explorer as with landlord, land-hunger was the master impulse of the era. The various desires which stimulated and promoted westward expansion were, to be sure, often found in complete conjunction. The trader sought to exploit the Indian for his own advantage, selling him whisky, trinkets, and firearms in return for rich furs and costly peltries; yet he was often a hunter himself and collected great stores of peltries as the result of his solitary and protracted hunting-expeditions. The rancher and the herder sought to exploit the natural vegetation of marsh and upland, the cane-brakes and pea-vines; yet the constantly recurring need for fresh pasturage made him a pioneer also, drove him ever nearer to the mountains, and furnished the economic motive for his westward advance. The small farmer needed the virgin soil of the new region, the alluvial river-bottoms, and the open prairies, for the cultivation of his crops and the grazing of his cattle; yet in the intervals between the tasks of farm life he scoured the wilderness in search of game and spied out new lands for future settlement.
