The agricultural revolution in the 19th century involved two things ：the invention of labor-saving machinery and the deyelopment of scientific agriculture.Labor-saving machinery naturally appeared first where labor was scarce. “In Europe ，”said Thomas Jefferson ，“the object is to make the most of their land ，labor being abundant：here it is to make the most of our labor ，land being abundant. ”It was in America ， therefore，that the great advances in 19th century agricultural machinery first came. At the opening of the century ，with the exception of a crude plow farmers could have carried pracically all of the existing agricultural implements on their backs ;by1860，most of the machinery inuse 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 introdueing his invention.The farmers，however，would have none of it ，claiming that the iron poisoned the soil and made the weeds grow.Nevertheless，many people devoted their attention to the plow ，until in 1869 James Oliver of South Bend ，Indiana，turned out the first chilled-still plow. ? 1.
