WEATHER BUREAU. 69 



of the National "Weather and Crop BuUetm, copies of the weekly 

 summaries telegraphed to the central office for use in the bulletin, 

 expanded as necessary. This service has recently been extended 

 so that these summaries are furnished to each Weather Bureau 

 station in the respective States, to be given to the pubUc at the 

 appomted hour. 



Snow and ice bulletins were issued weekly during the past winter, 

 as usual, and the snow bulletins for the western Mountain States, 

 issued monthly, were, as a rule, considerably enlarged over those 

 issued for previous years, and contained much additional information 

 regardmg the amount and condition of the snow stored in the higher 

 mountains. 



The monthly and annual publications of the climatological service 

 of the several States have been published regularly, furnishing prompt 

 means for distributing the information they contain to the interested 

 public. The collection of these summaries for the respective States 

 into single volumes each month, containing a report for each State, 

 has been accomplished as promptljf as possible. The number of com- 

 plete sets now assembled and distributed has increased to nearly-450, 

 and requests to be listed for this publication are still being received. 



The daily bulletins for the corn and wheat, cotton, sugar and rice, 

 cattle, and other interests have all been issued regularly with a con- 

 tinued increase m the circulation. 



During the year the abridged set of climatic charts was brought 

 down to date, where necessary, and reprinted, and several important 

 additions were made to the set, notably four charts of average rela- 

 tive humidity at 8 a. m. and 8 p. m., January and July, and two of 

 the average temperature for the same months. On account of the 

 numerous demands for Bulletin V, Frost Data of the United States, 

 the supply became exhausted and a reprint necessary, which was 

 accomplished during the year. 



Calls for climatological and other data continued as in previous 

 years, the total number of such requests handled at Washington 

 being about 5,000. 



The numerous calls for the data contained in the summaries of 

 climatological data by sections. Bulletin W, exhausted some of the 

 separate parts, and new editions of several of the individual sections 

 have become necessary. Some of these have been printed already 

 and others are now ready to go to the printer. 



Durmg the year a large amount of work has been accomplished 

 in compiling climatological data for a proposed atlas of agricultural 

 meteorolog}^ in cooperation with other bureaus of the department, 

 the largest individual piece of work being the reduction of the pre- 

 cipitation data for the 20-ycar period 1895 to 1914, inclusive, to a 

 uniform basis. This has necessitated the compilation of the reports 

 from about 3,000 different points throughout the United States, the 

 computation of means, and the establishment of the ratios of the 

 short records to the full 20-year period. Much assistance has been 

 given in this work by the station officials, who have cheerfully re- 

 sponded to every call made upon them. The work is now well 

 advanced, and the material g;athered will be of much value to the 

 Bureau in addition to serving the purpose for which originally 

 gathered.
