Contains twenty-three charts as follows: Monthly rainfall, seasonal rainfall, annual rainfall, monthly snowfall, monthly maxima of rainfall, rainy seasons, details of rainfall, details of occurrence of thunderstorms. Well adapted to serve as illustrations for use in the class-room. The text is explanatory, and is published separately in quarto form.

Rainfall of the United States, with Annual, Seasonal, and other Charts. Alfred J. Henry. United States Department of Agriculture, Weather Bureau, Bulletin D, Washington, D. C. 1897. 914 × 1112 inches. Pp. 58. Charts 10. Plates III.

A more recent publication than the preceding one, the averages having been compiled to the end of 1896. The charts are smaller than most of those in Bulletin C, and therefore not so well adapted for class-room illustration. The chart of mean annual precipitation is the latest and best published. The rainfall of the crop-growing season receives separate treatment, and is illustrated by means of two charts. The discussion in the text is excellent.
