States, which it is inteiuled Kriulually to cover in this mannor. The papers 

 will be of value to agriculturists, engineers requiring data on water resources, 

 and otlier citizens who seeli information regarding the climate of the several

Monthly Weather Review (Mo. Weather Rev., 37 (1909), Nos. 7, pp. 265-1,10, 

 figs. 7, charts S2; 8, pp. 411-550, charts 32; 9, pp. 551^696, figs. 2, charts 32; 10, 

 pp. 697-840, figs. 3, charts 32). — With the July number several important 

 changes were made in the contents of the Review. It now contains " represent- 

 ative climatological data covering the general climatology, the daily precipita- 

 tion, and daily maximum and minimum ten)peratures " for each of 12 climato- 

 logical districts, practically coinciding with the great drainage basins of tlie 

 United States. " The data for each of the 12 districts will be edited by local 

 representatives familiar with the country, who will prepare monthly summaries 

 made up from the notes written by the several section directors." 



Section bulletins will not be issued as heretofore, but separates will be avail- 

 able for distribution in the respective districts. 



The Review will continue to give " the usual data regarding the forecasts, 

 the river stages, the storm tracks, and similar matter. Resides these there will 

 be prepared each month several charts covering the climatology of the United 

 States, for the precipitation and the temperature conditions of the month." 



The change in form of publication was rendered desirable by the organization 

 of an inter-Bureau service, including the Forest Service and the Bureau of 

 Plant Industry of this Department, and the Reclamation Service, Water Re- 

 sources Branch of the Geological Survey, and Office of Indian Affairs of the In- 

 terior Department. 



"The purpose of this inter-Bureau cooperation is to secure observers to make 

 records of the amount and condition of the snowfall and rainfall along the 

 sources of the rivers utilized farther on by the irrigation and power projects at 

 lower levels. In a general way the U. S. Weather Bui'eau supplies the neces- 

 sary apparatus, instructs tlie observers, and makes a small payment for the tak- 

 ing of the required observations, while the cooperating Bureaus render most 

 valuable service in securing observers and in installing the apparatus. A good 

 F>eginning has been made in the work of organizing this inter-Bureau service in 

 respect to the water resources of the semiarid regions of the West, but it will 

 take some time to extend it as far as required by the demands of the people." 



The four numbers here noted contain climatological summaries for the 12 

 climatic districts referred to above, weather forecasts and warnings for July, 

 August, September, and October, 1909, respectively, river and flood observations, 

 special papers on general meteorology, including lists of additions to the 

 Weather Bureau library and of recent papers on meteorology and seismology, a 

 condensed climatological summary, and climatological tables and charts. 



Meteorological observations at the Massachusetts Agricultural Experi- 

 ment Station, J. E. Ostrander and C. M. Damon (Massachusetts 8ta. Met. 

 Bills. 251, 252, pp. 4 each). — Summaries of observations on pressure, tempera- 

 ture, humidity, precipitation, wind, sunshine, cloudiness, and casual phenomena 

 during November and December, 1909. are presented. The general character of 

 the weather of each month is briefly discussed, and the December bulletin gives 

 a summary for the year. The principal data in this summary are as follows: 



Pressure, reduced to freezing and sea level (inches). — Maximum, 30.75, Jan- 

 uary S and 16; minimum, 28.84, March 2.5; mean, 30.006. Air tcmpcratm'e, 

 in ground shelter (degrees F.). — Maximum, 94, August 8; minimum, — 8.5. 

 December 30 ; mean, 46.8. Humidity. — Mean dew-point, 38.2 ; mean relative 

 humidity, 76.8. Precipitation. — Total rainfall or melted snow, 39.12 in.; num- 

 ber of days on which 0.01 in. or more rain or melted snow fell, 128; total snow-
