nvented a castiron plough, and spent about $30,000 in perfecting it. It proved a great loss and failure to him, however, for the report spread among the farmers that the new plough poisoned the soil, ruined the crops, and promoted the growth of rocks ; and, as they refused to use it, the manufacture of the new invention ceased. About 1804 Daniel Peacock patented a plough having its mould-board and landside of cast-iron and separate, while its share was of wrought-iron, edged with steel. Jethro Wood, of Scipio, N. Y., patented improvements on this in 1819, and the prejudice against new inventions among farmers having somewhat abated, he did a very successful business as a maker of these implements, and his plans have been the basis of most all those of modern construction. The first steam-plough in the United States was patented by E. C. Bellinger, of South Carolina, in 1833, but did not come into practical use until much later. Perhaps the Great plough. invented by Daniel Webst
th sheet-iron or plates made by hammering out old horseshoes. Jefferson studied and wrote on the subject, to determine the proper shape of the mold-board. He treated it as consisting of a lifting and an upsetting wedge, with an easy connecting curve. Newbold of New Jersey, in 1797, patented a plow with a mold-board, share, and landside all cast together. Peacock, in his patent of 1807, cast his plow in three pieces, the point of the colter entering a notch in the breast of the share. Jethro Wood of Scipio, N Y., patented improvements in 1819, and made the best plows up to date. He met with great opposition and then with much injustice, losing a competence in introducing his plow and fighting infringers. The peculiar merit of his plow consisted in the mode of securing the cast-iron portions together by lugs and locking pieces, doing away with screw-bolts and much weight, complexity, and expense. It was the first plow in which the parts most exposed to wear could be renewed in t
