Notes:
NOTE.—The Geological Survey is making a topographic map of the United States. The sheets of which it is composed are projected without reference to political divisions, and are designated by some prominent feature found on them. Three scalesare used, 1:62,500, 1:125,00 1, and 1:250,000. These correspond, approximately, to 1 mile, 2 miles, and 4 miles to 1 linear inch on the map. The size, unless otherwise given, is about 17½ inches in height by 11½ to 16 inches in width, exclusive of the margin, the width varying with the latitude. About one-fifth of the area of the country, excluding Alaska, has been mapped, nearly every State being represented. Massachusetts. Connecticut, Rhode Island, New Jersey, and the District of Columbia are completely mapped. A description of the topographic map is printed on the reverse of each sheet catalogued below and they are sold by the Survey at 5c. each.
