本文探讨了西进运动期间，美国农民面对东部贫瘠土地和土壤退化的挑战，转向西部肥沃土地的过程。西部的河流冲积平原、森林地带及大草原的黑土吸引了来自新英格兰和东南部的农民。然而，将农作物从西部运往东部市场的成本高昂，促使了运输方式的革新，如修建收费公路，以降低运输成本并刺激沿线农业的商品化进程。

The West had plenty of attractions: the alluvial river bottoms, the fecund soils of the rolling forest lands, the black loams of the prairies were tempting to New England farmers working their rocky, sterile land and to southeastern farmers plagued with soil depletion and erosion.

Livestock could be driven across the mountains, but the cost of transporting bulky grains in this fashion was several times greater than their value in eastern markets. In fact, goods could be shipped more cheaply across the much greater distance of the Atlantic Ocean than they could from western New York to coastal cities. The first step toward an improvement of western transportation was the construction of turnpikes. These roads made possible a reduction in transportation costs and thus stimulated the commercialization of agriculture along their routes.
