The agricultural revolution in the nineteenth century involved two things: the invention of labor-saving *chinery and the development of scientific agriculture. Labor-saving *chinery naturally appeared first where labor was scarce. "In Europe, said Tho*s Jefferson, "the object is to *ke the most of their land, labor being abundant: here it is to *ke the most of our labor, land being abundant. It was in the United States, therefore, that the great advances in nineteenth-century agricultural *chinery 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 implements on their backs; by 1860, most of the *chinery in use today had been designed in an early form. The most important of the 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, were not interested in it, claiming that the iron poisoned the soil and *de the weeds grow. Nevertheless, *ny people devoted their attention to the plow, until in 1869 James Oliver of South Bend, Indiana, turned out the first chilled-steel plow.
