This stone wall was built as farmers cleared land to confine livestock and mark boundaries. In 1872, the U.S. Department of Agriculture reported that there were approximately 240,000 miles of stone walls throughout New England. Livestock were enclosed by stones that were uniform in size, whereas stones used to mark boundaries often varied in size from full-boulders to small stones.
Can you tell the purpose of this stone wall? Hint: Are the stones similar in size or do they vary in size?
