The agriculture revolution in the nineteenth century involved two things: the inventi

on of labor-saving machinery and the development 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 sufficient; here it is to make the most of our labor, land being abundant." It was in America, therefore, that the great advances in nineteenth-century agricultural machinery first came. At the opening of the century, with the exception of a crude (粗糙的) plow, farmers could have carried practically all of the existing agricultural tools on their backs. (80) By 1860, most of the machinery in use today had been designed in an early form. The most important of the early inventions was the iron plow. As early as 1890 Charles Newbolt 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, claiming that the iron poisoned the soil and made the weeds grow. Nevertheless, many people devoted their attention to the plow, until in 1896, James Oliver of South Bend, Indiana, turned out the first chilled-steel plow.

The Word "here" (Para, 1, Line 3) refers to ______.

A．Europe

B．America

C．New Jersey

D．Indiana

Meteorite worship was common long in the Mediterranean area, and in Africa, India, Japan, and Mexico: such worship still persists in some regions.

Although many people held meteorites in reverence paritcularly if they were seen to fall, other practical minded individuals made good use of the durable and easily worked alloy provided by nature in the nickel-iron meteorites. They frequently used of this metal to make tools, and often pots and other utensils. Throughout history, meteoritic iron has been used in the manufacture of special swords, daggers, and knives for members of royalty. Attila and other early conquerors of Europe. boasted of "swords form. heaven". As late as the end of nineteenth century, several swords were made from a Japanese iron meteorite at the command of a member of the Japanese court.
