A rubber stamp in the form of a 100% bar chart with the percentages marked may be

secured from stores handling graphic chart material or from makers of rubber stamps.

2. When a bar chart is wanted in a report, all that is necessary is to allow two inches

height and six inches length in the manuscript. The chart may then be placed in this space.

3. These rubber stamps may be secured in other sizes, but they are usually six inches

long. Paper on which five 100% bars have been printed is also available. This illustration may be used as copy for making a rubber stamp.

"The Ffdcral Chart Book." Prepared by the Central Statistical Board arid National Reiource* Committee, January, 1Q38. SCALE .8

A. Estimated Tonnage in the United States Originated by Principal Types of Carriers in 1932.

1. In this chart a comparison of weights is given rather than amounts or percentages, and

the scale is separated from the 100% bar.

2. The value of this chart would have been increased if the tonnage for each of the four

divisions had been given.

3. The choice of shadings was unfortunate, since at the point where the two sections,

"waterways" and "highways," meet, the bar seems to sag.

4. The Federal Chart Book is an experimental publication and does not stand as a document for general use. As a result, the illustrations are in a tentative and not necessarily final form.
