Silos were first built in the
United States in 1875 .The first silos, a concept borrowed from Europe, were
pits in the ground for storing silage, usually chopped green corn. Soon silo
designers went up in the air instead, and round structures became favored
because they posed no problematic corners. During World War I it was deemed
patriotic to have a silo, food production being the loyal duty of the rural
army. By 1924 the number of silos exceeded 100,000.
Changes in technology and the
disappearance of small family-based farms have become apparent in the number of
silos that are now standing abandoned in fallow fields. Some have been converted
for other uses such as dwellings and homes. Many of these silos stand as
striking reminders of of their area's traditional rural character and an earlier
way of life.
According to Wikipedia: A silo
is a structure for storing bulk materials. Silos are used in agriculture to
store grain (see grain elevators) or fermented feed known as silage. Silos are
more commonly used for bulk storage of grain, coal, cement, carbon black, wood
chips and sawdust.

of the silos we are looking for.
