WEATHER BUREAU. 93 



of the (lata and checking the various tables and charts devolved upon 

 the clerical force of the division, where, in order to facilitate the work, 

 much of the proofing, revising, and other details were attended to. 



New work. — The preparation of new normals of the daily maxi- 

 mum, daily minimum, and daily mean temperatures, the details of 

 which were outlined during the preceding year, was carried forward 

 as rapidly as the press of other work permitted. At the end of the 

 year nearly all the stations having 40 or more years of record, some 

 To or more, had been practically completed and most of them for- 

 warded to stations for current use. 



Considerable progress was made on a proposed new system for 

 maintaining the summarized weather data accumulated at the various 

 State section centers, but on account of prospective world-wide 

 changes in the calendar, now being discussed, it was deemed best to 

 delay any extensive changes at the present time. 



The preparation of new normals of daily maximum, daily mini- 

 mum, and daily means of temperature for the short-record stations 

 of the bureau will be the principal extra work in the division during 

 the present fiscal year. 



Loyal support has been given by each member of the division's 

 clerical force. 



PRINTING. 



The mailing lists of the bureau have all been revised and brought 

 up to date, resulting in the discontinuance of a number of subscrip- 

 tions. The demand for Weather Bureau publications from the gen- 

 eral public, especially libraries, schools, and colleges, continues to be 

 large. All applications are receiving prompt, careful, and favorable 

 consideration where possible. In case the publications can not be 

 supplied the writer is so advised, and if possible the source from 

 which the publication may be secured. 



Under a provision of the sundry civil act of March 4, 1921, Gov- 

 ernment departments were required to suspend the publication of 

 all periodicals not otherwise specifically authorized by law. The 

 National Weather and Crop Bulletin and the Monthly Weather 

 Review were therefore suspended with the issue of December. 1921. 

 Later the Weather and Crop Bulletin was combined with the Market 

 Reporter and the Monthly Crop Reporter on January 7, 1922, and is 

 now issued weekly throughout the year by the Department of Agri- 

 culture under the title, "Weather, Crops, and Markets." The re- 

 sumption of the issue of the Monthly Weather Review was also 

 authorized. 



Under the deficiency bill passed by Congress for printing and bind- 

 ing of the Department of Agriculture, the Weather Bureau was 

 enabled to effect the printing of a considerable amount of back 

 climatological statistics, river stages on the principal rivers of the 

 United States for 1920 and 1921, and the binding of official records. 

 A large amount of this important data had accumulated during the 

 war and since, and the amount of printing and binding accom- 

 plished under this appropriation has materially facilitated the 

 work of the bureau. 



In accordance with existing regulations the utmost economy was 

 practiced in the issuance of publications and the purchase of paper, 

 ink, and other printing materials. No new or additional machinery 

 or equipment was installed during the year.
