The routing of work through the many processes and departments of a large plant is a subject of such great importance that charts are frequently desired for the study of such routing. Fig. 14 is a fairlv good example of this class of chart. In a complete chart, the departments would of course be designated for easy reference, by names, numbers, or letters. Colored ink could be used to keep one class of work distinct from another. Colored inks would help tremendously

in simplifying Fig. 14, but are not available here because of the prohibitive expense of color printing. Colored drawing inks can be obtained at almost any stationery store. A bottle of each color should be a part of the equipment of any person who is regularly doing chart work. Note in Fig. 1-4 the small curves drawn where one route line crosses another line. By means of small curves like these it is very easy to keep the lines separate and to show- clearly that the lines crossing each other are entirely independent.

Orders and other printed forms sent through a large organization must follow a routing entirely distinct from that actually followed bj' the heavy materials. The routing of printed forms in a large business is, in itself, a matter worthy of most careful study to get a true understanding of their complex movements. A clear idea of office system is almost impossible unless the data are charted. Fig. 15 may give some suggestions for a chart to show the movement of printed forms through an industrial plant.
