A grain sack of homespun linen made from flax grown on the John Lesher farm near Waynesboro, Pennsylvania. Woven at a roadside mill, the sack has a capacity of three bushels and is marked "John Lesher, No. 26, 1842." Prior to the advent of and widespread use of the elevator system of grain handling, nearly all grain was moved in sacks that had to be shifted about by hand and stored in warehouses. The elevator system began in Buffalo, New York, in 1842, but reached a position of prominence only in the 1870s when it began flourishing in Chicago and Milwaukee. Thereafter the grain sack became virtually a curiosity. Gift of James W. Brown, Brookeville, Maryland. 123. Single-Harpoon Hayfork, about 1895. USNM 216224; 1957.
