Created in the late 1800s, this giant horseshoe may not look like much, but it revolutionized farming in the California Delta by allowing more land to be used for agriculture. Even though Chinese immigrants were not allowed to own land, laborers from China farmed the marshy land of the Delta and developed the tule horseshoe to compensate for the difﬁ cult farming conditions of the region. The soft peat soil of the Delta was difﬁ cult for horses to work in; they became bogged down and often they panicked, risking injury to themselves and their drivers.
To overcome this problem, Chinese laborers developed an oversized horseshoe made
out of wood planks.
