41. Ox Yoke, 1838. USNM 148675; 1938. Edward Scoville (1813-1887) used this ox yoke when driving an ox cart from Trumbull County, Ohio, to De Kalb County, Indiana, in 1838. Until well after the Civil War, oxen pulled most of the wagons going west, and this yoke is typical of all used in the westward migration, in the North as well as in the South. Gift of Reign Scoville, Poplar Bluff, Missouri. [Illustration: Figure 5.--John Deere plow, one of the three plows made by Deere in 1838. (Catalog No. 42.)] 42. Deere Plow, 1838. USNM 148904; 1938. John Deere made this plow, with steel share and polished wrought-iron moldboard, at Grand Detour, Illinois, in 1838. Joseph Brierton bought it and used it on his farm, and the Deere Company obtained it in 1901. It is one of three plows made by John Deere in 1838, and presumably it is identical to his first steel share plow, made in 1837 at Grand Detour. Called the singing plow, it proved especially effective in prairie country after the sod had been broken because the earth did not adhere to the share and moldboard. The implement could also be used as a breaking plow. Gift of Deere and Company, Moline, Illinois. 43. Model of Sulky Plow, 1899. USNM 156653; 1940. Working model of the Hy-Lift sulky plow invented by Niels O. Starks of Madison, Wisconsin, and made by the Fuller and Johnson Company around 1900. Starks received patent 616984 on January 3, 1899. The land wheel on this plow automatically raises and lowers the plow at the end of a furrow. Gift of S. O. Strucksberg, St. Joseph, Missouri. 44. Barbed Ribbon Wire, 1879. USNM 159858; 1941. Specimen of barbed wire made with saw teeth cut out of twisted ribbon wire. Gift of B. F. Arthur, Winchester, Virginia. 45. Chinese Plow, date unknown. USNM 161555; 1941. This primitive, one-handled plow has an iron hook on the end of the beam. Apparently it had an iron shoe for a share, which is now missing. This style of plow is typical of the kind used in rice-growing sections of China. Gift of United States Department of Agriculture. 46. Carey Plow, about 1820. USNM 161555; 1941. The share and landside of this small cultivating plow are in one piece of wrought iron with sockets for the left handle and the standard bar share. It has a flat wooden moldboard. Used in Northumberland County, Virginia, until 1855 or 1860, for cultivating corn and other row crops. Gift of United States Department of Agriculture. 47. Plow, about 1790. USNM 161555; 1941. Only the share, colter, and beam of this plow are original, the rest having been reconstructed. The original parts came from Northumberland County, Virginia. Gift of Edwin Brown, Brown's Store, Virginia.
