By 1850 the national territory stretched over forest,
plain and mountain. Within these far-flung limits dwelt 23 million people
in a union comprising 31 states. In the East, industry boomed. In the
Midwest and the South, agriculture flourished. After 1849 the gold mines
of California poured a golden stream into the channels of trade.
New England and the Middle Atlantic states were the
main centers of manufacturing, commerce and finance. Principal products
of these areas were textiles, lumber, clothing, machinery, leather and
woolen goods. At the same time, shipping had reached the height of its
prosperity, and vessels flying the American flag plied the oceans, distributing
wares of all nations.
The South, from the Atlantic to the Mississippi River
and beyond, was a relatively compact political unit featuring an economy
centered on agriculture. Tobacco was important to the economies of Virginia,
Maryland and North Carolina. In South Carolina, rice was an abundant
crop, and the climate and soil of Louisiana encouraged the cultivation
of sugar. But cotton eventually became the dominant crop and the one
with which the South was identified. By 1850 the American South grew
more than 80 percent of the world's cotton. Slaves were used to cultivate
all these crops, though cotton most of all.
The Midwest, with its boundless prairies and swiftly
growing population, flourished. Europe and the older settled parts of
America demanded its wheat and meat products. The introduction of labor-saving
implements -- notably the McCormick reaper -- made possible an unparalleled
increase in farm production. The nation's wheat crops meanwhile swelled
from some 35 million hectoliters in 1850 to nearly 61 million in 1860,
more than half being grown in the Midwest.
An important stimulus to western prosperity was the
great improvement in transportation facilities; from 1850 to 1857 the
Appalachian Mountain barrier was pierced by five railway trunk lines
linking the Midwest and the East. These links established the economic
interests that undergirded the political alliance of the Union from
1861 to 1865. In the expansion of the railway network, the South at
first had much less part. It was not until the late 1850s that a continuous
line ran through the mountains connecting the lower Mississippi River
with the southern Atlantic seaboard.
