Erosion
Erosion is the wearing away of earth
or rock. Since the earth was formed erosion has taken place. George
Washington was aware of erosion in the farm fields and wanted to
stop this washing of gullies in the fields by planting grass. The
following excerpt is from a letter George Washington wrote to one
of his farm managers (overseers) on January 27, 1793:
"I wish you may not find No. 4 and
5 at the River Plantation very unproductive fields; and very injurious
to break, unless it is done with judgment. My intention was to keep
them for common pasture; To have endeavoured to stop the gullies;
and to have prevented the washed places from getting worse by covering
them with Straw; and to have sown the Seeds of the common locust
thereon, or something that would (in a few years, have cloathed
it with a growth that would have proved a remedy for the present
evil. That field is very apt to wash, at present it is very much
gullied, and if uncommon attention is not paid to it in the working
and in laying it down it will be unfit hereafter for grass even
except in a few spots." (Fitzpatrick, John C., The Writings of George
Washington, Washington, D.C.: United States George Washington Bicentennial
Commission, 1939, Vol. 32, p. 319.)
Erosion changed the way the land features
looked in George Washington's time. Think of how much the landscape
today has changed since George Washington surveyed. These pictures
are examples of different agents of erosion on different types of
landscapes.
