The ability to read maps is an absolutely essential qualification of a medical officer. Instructions conveyed to him in the field often contain references to maps. If he is unable to understand these references his efficiency is greatly impaired. Then, too, the question of shelter and cover from fire at distant points at which it might be desirable to establish sanitary formations can often be determined by reference to maps.

As the shortest road to map reading is through map making, the essentials of map making will be outlined. Ordinarily in two afternoons the general principles of map making can be mastered. In working out the principles of map making the essentials of map reading will be absorbed unconsciously.

ARTICLES NEEDED FOR MAP MAKING  Compass, alidade, slope board, tripod, paper, four thumb tacks, pencil with eraser, a pace tallier (convenient but not essential), a list of pace scales for paces
