 conditions attending its preparation. 



The I*orto Kico section was enlarged to include the new West 

 Indian Climatological Service, with headquarters at San Juan, and 

 considerable delay in printing the monthly issues resulted from the 

 ^•reatly increased number of stations reporting under the new plan 

 of cooperation inaugurated with the various foreign governments in 

 that reoion. • 



To meet the needs of engineers and others in California, w^ho are 

 interested in the seasonal precipitation of that State as affecting 

 stream flow and water supply, the section director was authorized to 

 issue as a supplement to the June, 1922, monthly section report, and 

 yearly thereafter, a statement of the monthly precipitation at all 

 stations in that State for the rain year, July, 1921, to June, 1922, 

 inclusive, together with the total for the season. This permits the 

 bringing together in consecutive order the precipitation for the rainy 

 season and enables a more ready means of studying the water prob- 

 lems of that State. 



The snowfall bulletins for the 11 mountain States of the West were 

 issued as usual, and somewhat more data were discussed than in 

 previous years, due to increased facilities for obtaining reports. 



Collection and care of meteorological re port h. — All reports con- 

 taining meteorological data usually forwarded to this division were 

 properly checked, filed, and later prepared for permanent binding. 



The reports from the 42 climatological sections of continental 

 United States, about H20 copies for each section, were assembled

 promptly distributed to foreign weather institutions, libraries, or 

 other public repositories, and to subscribers and others making use

 reports for file at stations, consisting of about 140 sets. 5 volumes 

 each, a total of 700 volumes, was assembled, permanently bound, and 

 distributed to the more im]')ortant stations. Altogether nearly 1.800 

 separate volumes of reports of all kinds, not including those tem-

 division during the year, alphabetically and chronologically ar- 

 ranged, permanently bound, and placed in the proper files. 



Additional uwrh accom-plished. — During the 3'ear just closed op- 

 I)ortunity was afforded to secure the reprinting of a number of the 

 separate sections of Bulletin W, Summary of the Climatological 

 Data for the United States by sections, many of the sections being 

 entirely exhausted and the editions of others too old to enable their 

 efficient use in answering calls for weather data. 



By concerted action between station officials and this division. 26 

 of the 106 sections were brought down to the end of 1920, with new 

 tables added, and reprinted. Material for 24 additional sections was 

 forwarded to the Government Printing Office and these are in process 

 of completion, and 17 others are now ready, awaiting allotment of 

 necessary funds, while the remaining numbers are in various stages 

 of progress at the respective centers, but will all be ready for print-
