The Preparation of Illustrations for Reports of the United States Geological Survey / With Brief Descriptions of Processes of Reproduction

TITLE.

The title of a map should be in roman letters and if placed at the lower margin should generally be arranged in two lines, unless it is short. If it forms two or more lines the lines should be well balanced. The first line should describe the position of the area; the second line should state the purpose of the map, as

MAP OF BUTTE AND VICINITY, MONTANA
SHOWING LOCATION OF MINES AND PROSPECTS.

A title placed inside the border of a map should be arranged in a series of lines, generally beginning with "Map of" or "Geologic map of." and the line showing the dominant part of the title should be emphasized by larger lettering, thus:

MAP OF
THE VICINITY OF BUTTE
MONTANA
SHOWING LOCATION OF MINES AND PROSPECTS.

The name of the author or compiler of a map or of the person supplying the geologic or other data shown on it may be placed either beneath the title or in the lower right corner, just below the border line, and the names of the topographers or the source of the base should be stated in the lower left corner, just below the border line. If the title is placed inside the border all notes giving credit for any part or features of the map may be placed beneath the title or scale. (See [PI. VII].)
