    tions are of different colors, one color representing each race group. (See page . Pin maps are a common form of visual representation of statistics. They make an immediate appeal to the public and are usually more readily understood than many forms of charts or graphs. In order to construct a pin map an ordinary map of the community, about 2x4 feet in size, should be tacked to a piece of compo board. Pins with large heads of different colors are used. In constructing a map to illustrate births and infant deaths, a pin with a white head should be stuck in the map at the exact location where the birth occurs. Deaths are illustrated by using pins with different colored heads to show the cause of death—red for contagious disease, yellow for diarrhceal disease, green for deaths from respiratory diseases, blue for congenital dis¬ eases, and black pins for deaths from all other causes. These maps are usually arranged to cover a definite length of time. They may be commenced at the beginning of the year and pins added as births and deaths occur. From such a map one is able to see at a glance the approximate number of births and just where they have occurred, also the approx¬ imate number of deaths from each type of illness, where these deaths have occurred, and any grouping of deaths that might have significance. Such maps are of particular value for persons who are engaged in child-hygiene work. For a busy executive they furnish one of the easiest methods of determining each dav the exact situation in any locality. For a more intimate knowledge of the situation these maps may be used to show the births and deaths occurring in one week. The pins may then be removed and a new week’s record begun.
