In some parts of the Unites States,farming is easy.But farming has always been difficult in the north-eastern corner of the country,which is called New England.
New England has many trees and thin,rocky soil.Anyone who wants to start a farm here has had to work very hard.The first job is to cut down all the trees.The next job is to dig the stumps （树桩） of the trees out of the soil.Then the farmer has the most difficult job of all,removing stones from his land,which never really ends,because every winter more stones appear.They come up through the thin soil from the rocks below.Farmers have to keep removing stones from the fields.Even today,farms which have been worked on for 200 years keep producing more stones.
That is why stone walls are used instead of fences around the new England fields.The stone walls are not high,and can easily be climbed,but they keep the farmer‟s cow from joining his neighbour‟ cattle.
