settlements and the eastern centers, following the trails of the
trader and the more beaten paths of emigration. The bolder
settlers who ventured farthest to the westward were held in
communication with the East through their dependence upon salt
and other necessities of life; and the search for salt-springs in
the virgin wilderness was an inevitable consequence of the desire
of the pioneer to shake off his dependence upon the coast.

The prime determinative principle of the progressive American
civilization of the eighteenth century was the passion for the
acquisition of land. The struggle for economic independence
developed the germ of American liberty and became the
differentiating principle of American character. Here was a vast
unappropriated region in the interior of the continent to be had
for the seeking, which served as lure and inspiration to the man
daring enough to risk his all in its acquisition. It was in
accordance with human nature and the principles of political
economy that this unknown extent of uninhabited transmontane
land, widely renowned for beauty, richness, and fertility, should
excite grandiose dreams in the minds of English and Colonials
alike. England was said to be "New Land mad and everybody there
has his eye fixed on this country." Groups of wealthy or
well-to-do individuals organized themselves into land companies
for the colonization and exploitation of the West. The pioneer
promoter was a powerful creative force in westward expansion; and
the activities of the early land companies were decisive factors
in the colonization of the wilderness. Whether acting under the
authority of a crown grant or proceeding on their own authority,
the land companies tended to give stability and permanence to
settlements otherwise hazardous and insecure.
