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 town or natural feature found on them. Three scales are ordinarily used, 1:62,500, 1:125,000, and 1:250,000. These correspond approximately, to 1 mile, 2 miles, and 4 miles to 1 linear inch, covering, respectively, average areas of 2110, 920, and 3,700 square miles. For some areas of particular importance special large-scale maps are published. The size, unless otherwise given, is about 17.5 inches in height by 11.5 to 16 inches in width, exclusive of the margin, the width varying with the latitude. A description of the topographic map is printed on the reverse of each sheet. More than one-third of the area of the country, excluding outlying possessions, has been mapped, every State being represented. Massachusetts, Connecticut, Rhode Island, New Jersey, and the District of Columbia are completely mapped. Sheets of the regular size are sold by the Survey at 5c. each; but in lots of 100 or more copies, whether of the same sheet or of different sheets, the price is 3c. each. In no case can orders be filled at the wholesale rate unless the sum remitted solely for topographic maps amounts to at least $3.00.
