Distance is shown by what is known as scale. It would be impossible and unnecessary in making a map to use the exact measurements of distances existing in any given portion of the country, but we can indicate those distances by drawing our map even though very small so that lines, angles, circles and dots will bear the same relation to each other as the points they represent bear to each other. This is done by using a small measure to represent a large measure. If 1 inch was used to represent a mile, a map showing 80 square miles of ground, measuring 8x10 miles could be drawn on a comparatively small piece of paper. Whatever scale is used must be noted on the map, however. The true distances are found by pacing or by triangulation. The interesting, helpful and necessary points are learned by observation. These are the real guides when using a map and these should be placed most correctly. Some of the symbols most generally used in map making are shown in the accompanying cut. To be able to read a map is quite as important as making one. Signs must be understood, distances read, and directions known. It will help in ascertaining the latter point to hold the map so its position will be true to the points of the compass--the East to the East. This is called orienting a map.
