seismological work, and that appropriations therefor should be made 

 through the Weather Bureau. This action of the committee was 

 not only unanimous, but was heartily concurred in by the heads of 

 all Government bureaus either directly or indirectly interested in the 

 questions involved. 



CLIMATOLOGICAL DIVISION. 



The issue of the IVIonthly Weather Review in its new form, begun 

 July, 1009, was considerably delayed during the first part of the year, 

 but has since been brought practically up to date. The publication 

 of the National Weather Bulletin was continued as in past years, 

 weekly during the crop-growing season and monthly at other times. 

 Weekly summaries of the snow and ice conditions were issued regu- 

 larly during the winter, as were also the snowfall bulletins from the 

 mountain States of the West. The latter have been considerably 

 enlarged, owing to the extension of the special snowfall stations into 

 regions not heretofore covered by reports. A special effort will be 

 made in March and April to give the public an idea of the amount 

 and condition of the snow actually lying on the mountains just before 

 warm weather sets it flowing into the streams. Weekly and monthly 

 summaries of climatological data continue to be issued at the Iowa, 

 Porto Rico, and Hawaii centers, as in the past, but the publication of 

 these summaries for the remaining sections was discontinued with the 

 issues for June, 1909. 



The current work of preparing data for the Monthly Weather 

 Review and the Annual Report of the Chief of Bureau, the tabula- 

 tion of the usual data into the permanent records of the Bureau, and 

 the preparation of matter called for by numerous correspondents 

 desiring information regarding the climate in various portions of 

 the coantry, have been carried forward as usual. 



The numerous requests for climatic data show an increasing knowl- 

 edge of the information avaiL^ble for the public, and indicate the 

 wide diversity of uses to which it is being put. Nearly 4,000 such 

 requests received prompt attention during the year. 



No material change has occurred in the cooperative work carried 

 on by the Bureau. Cooperation with other bureaus of the Depart- 

 ment and with the Geological Survey and Reclamation Service, in the 

 gathering of information regarding the snowfall in the mountain 

 regions of the West and the study of special problems in forestry and 

 plant growth, has continued with apparently satisfactory results to 

 all concerned. 



The changes in the form of some of the current climatological 

 publications of the Weather Bureau were made during the year in 

 order to accommodate more fully than heretofore the requirements 

 both of the public and of the General Government in developing the 

 water resources of the United States, especially in connection with 

 irrigation and transportation enterprises, as well as the many other 

 public interests which have hitherto been served by these publica- 

 tions. Accordingly the material of which the Monthly "Weather 

 Review was formerly composed has been separated into two general 

 parts: Terhnicnl articles on researcli problems in meteorology appear 

 in the Mount Weather Quarterly Bulletin, while the more practical 

 papers on engineering and commercial interests are still published in 

 the Monthly Weather Review. Similarly, the data formerly pub-
