In this chapter, divisions of the bars are made without reducing all bars to the same length.

PRIVATE WORf

Federal Reserve Agent, New York, "Monthly Review," Feb. 1, 1937. SCALE .7

A. Total Value of Building and Engineering Contracts in Thirtyseven of the United States, Showing the Proportion of Private and Public Construction from 1932 to 1936.

1. Here the component parts arc labelled

in percentages, facilitating the reading of the chart.

2. Since there are so few horizontal rulings, it might have been better to give the numerical values of each bar.

Federal Reserve Agent, New York, "Monthly Review," Nov. 1, 1936. SCALE .8

B. Comparison of the Gold Holdings of the Central Banks and Governments of 51 Other Countries and the United States in July 1931. and October 1936.

1. To prevent the reading of the top

figures as the items for the 51 other countries, there should be a third set of figures placed in a position similar to the item for the United States.

2. Since both the vertical scale and the

labels are put to the left of the bars, it may be more difficult to read the chart than if one or the other were placed to the right.
