unscrupulous, and immoral--the expansionist movement upon the
American continent would have been greatly retarded.

So scattered and ramified were the enterprises and expeditions of
the traders with the Indians that the frontier which they
established was at best both shifting and unstable. Following far
in the wake of these advance agents of the civilization which
they so often disgraced, came the cattle-herder or rancher, who
took advantage of the extensive pastures and ranges along the
uplands and foot-hills to raise immense herds of cattle. Thus was
formed what might be called a rancher's frontier, thrust out in
advance of the ordinary farming settlements and serving as the
first serious barrier against the Indian invasion. The westward
movement of population is in this respect a direct advance from
the coast. Years before the influx into the Old Southwest of the
tides of settlement from the northeast, the more adventurous
struck straight westward in the wake of the fur-trader, and here
and there erected the cattle-ranges beyond the farming frontier
of the piedmont region. The wild horses and cattle which roamed
at will through the upland barrens and pea-vine pastures were
herded in and driven for sale to the city markets of the East.

The farming frontier of the piedmont plateau constituted the real
backbone of western settlement. The pioneering farmers, with the
adventurous instincts of the hunter and the explorer, plunged
deeper and ever deeper into the wilderness, lured on by the
prospect of free and still richer lands in the dim interior.
Settlements quickly sprang up in the neighborhood of military
posts or rude forts established to serve as safeguards against
hostile attack; and trade soon flourished between these
