Traditionally, the American farmer has always been independent and
hard-working. In the eighteenth century farmers were quite self-sufficient.
The farm family grew and made almost nothing it needed. The surplus crop {{U}} {{U}} 1 {{/U}} {{/U}}
would be sold to buy a few items in the local general store.
In 1860, because some of the farm population had moved to the city, {{U}} {{U}} 2 {{/U}} {{/U}}
yet eighty percent of the American population was still in the country. In
the late nineteen century, farm work and life were not much changed {{U}} {{U}} 3 {{/U}} {{/U}}
from that they had been in the old days. The farmer arose at dawn or {{U}} {{U}} 4 {{/U}} {{/U}}
before and had much work to do, with his own muscles like his chief {{U}} {{U}} 5 {{/U}} {{/U}}
source of power. He used axes, spades and other complicated tools. {{U}} {{U}} 6 {{/U}} {{/U}}
In his house cooking was done in wood-burning stoves, and the
kerosene lamp was the only improvement on the candle. The family's
recreation and social life chiefly consisted a drive in the wagon to the {{U}} {{U}} 7 {{/U}} {{/U}}
nearby small town or village to transact some business as well as to
chat with neighbors who had also come to town. The children attended
a small elementary school (often of just one room) to that they had to {{U}} {{U}} 8 {{/U}} {{/U}}
walk every day, possibly for a few miles. The school term was short so {{U}} {{U}} 9 {{/U}} {{/U}}
that the children could not help on the farm. {{U}} {{U}} 10 {{/U}} {{/U}}
Although the whole family worked, and life was not easy, farmers as a class were self-reliant and independent.
