A great change in agriculture in the
19th century included two things: the invention of labor-saying machines and the
development of scientific agriculture. Labor-saving machines naturally appeared
first where more labor was needed. "In Europe," said Thomas Jefferson, "the
object is to make good use of their land, labor being abundant (充裕的); here it is
to make good use of our labor, land being abundant." It was in America,
therefore, that the great advances in the 19th century agricultural machines
first came. At the opening of the century, with the exception of
a crude plow, farmers could have carried practically all of the existing
agricultural tools on their backs; by 1860, most of the machines in use today
had been designed in an early form. One of the most important early inventions
was the iron plow. As early as 1790 Charles Newbold of New Jersey had been
working on the idea of a cast-iron plow and spent his entire fortune in
introducing his invention. The farmers, however, would have none of it,
declaring that the iron poisoned the soil and made the weeds grow, however, many
people devoted their attention to the plow; until in 1869 James Oliver of South
Bend, Indiana, turned out the first chilled-steel
plow.
