Meteorolog'y and agriculture, W. N. Shaw (Jour. Scot. Met. Soc, S. ser., 

 16, No. 29, pp. 18-26). — This is the full paper, brief revievfs of vrbich have 

 already been noted (E. S. R., 28, p. 414). It discusses the losses due to adverse 

 weather conditions, the possible value of forecasts in reducing such losses, and 

 the separate elements of a good crop year, setting forth the need of the organi- 

 zation of the available statistics bearing on this question. 



Forecasting the weather, G. S. Bliss (U. S. Dept. Agr., Weather Bur. Bui. 

 Jf2, pp. 34, figs. Jf)- — The object of this bulletin is stated to be to present some of 

 the generally accepted facts and theories of meteorlogy in an elementary form 

 for wide circulation. 



Forecasting frost in the North Pacific States, E. A. Beals ( U. S. Dept. 

 Agr., Weather Bur. Bui. Jfl, pp. 49, figs. 13). — "The paper describes the evolu-

 Oregon, and Idaho, and contains detailed reports of the conditions under which 

 warnings were issued during the critical season in the spring of 1911 for the 

 fruit districts of Boise, Lewiston. Rogue River "Valley, and Yakima Valley. It 

 discusses the meteorological conditions which afford an indication of the prob- 

 able occurrence of frost and on which warnings may be based. The paper is 

 accompanied by three illustrations showing Weather Bureau equipment for 

 observing temperature conditions, sketches of the 4 fruit districts mentioned, 

 5 weather maps showing the conditions preceding frost, and a chart of com- 

 posite thermograph curves." 



A method of classification of winters, A. Angot (But. Soc. Nat. Agr. France, 

 13 (1913), No. 3, pp. 186-188). — The method proposed is to classify the winters 

 by means of the sum of minimum monthly temperatures below 0° C. The 

 method is applied to temperatures observed during the winters of 1872-73 and 

 1911-12 at Park Saint-Maur.
