SECOND CLASS SCOUT
Green
Green indicates heavy vegetation-areas covered with forests, wood- lands, or orchards.
White
White is used for areas that are mostly clear of trees. A white area on a map might he a field, meadow, rocky slope, or other form of open country.
Blue
Blue means water. A large patch of blue is usually a pond or a lake. A blue band is a river, and a blue line is a stream. If the line is broken, the stream it represents doesn't flow all of the time. Marshes and swamps are drawn with broken blue lines and tufts of grass. Names of all water features are given in italic type.
Black
Black ink is used on a map to show anything that is the work of humans. Rail lines, bridges, boundaries, and the names of landmarks are printed in black. Roads are shown as parallel black lines-solid for paved and gravel (improved) roads, broken for dirt (unimproved) roads. A single broken line is a hiking trail. Black squares and rectangles are buildings. Those that are solid black are inhabited-houses, schools, churches. Those that are just outlined in black are barns, sheds, and other outbuildings.
Brown
Brown is used for contour lines. Maps are flat, but the areas they represent might be full of hills, valleys, mountains, and plains. Each contour line represents a specific elevation above sea level; that is, the elevation remains the same at all points along any one contour line. Contour lines allow mapmakers to show the shape of the land.
