The value of weather forecasting in agriculture, W. II. Dunlop (Agr. Gaz. 

 [London^, 11 {1910), Aos. 1S82, p. S7 ; 1883, pp. 105, 106, flgs. J, ; 188-',, pp. 129, 

 130, figs. 3; 1885, pp. 153, 15^. flgs. 2; 1886, p. J77).— This article discusses in a 

 popular way and in some detail the selection of land with reference to meteor- 

 ological conditions; farm operations requiring weather forecasts; general 

 weather conditions of the British Isles; the relation of cyclones, anticyclones, 

 and cloud types to weather conditions ; thunderstorms ; popular weather signs ; 

 frost prediction and protection ; meteorological instruments ; and simple rules 

 for weather in'ognostication. 



The relation of the weather service to the farmers of Tennessee, J. F. Voor- 

 HEEs {Tennessee 8ta. Bui. 81, pp. 22, charts 13). — The various meteorological 

 elements are shown by means of charts prepared from observations at fi-om 

 50 to GO Weather Bureau stations distributed uniformly over the State. The 

 records from which the charts were prepared in most cases cover a period of 

 at least 13 years. The charts show the latest killing frost in the spring and 

 the earliest in the fall, as well as the average date of these frosts, average 

 number of days in the growing season, elevation of the stations above sea 

 level, mean annual temperature, lowest temperature in 1.3 years, number of 

 winters during that period with zero temperature or below, mean annual rain- 

 fall, and monthly distribution of rainfall at the different stations. 



The practical value of the meteorological data to the farmer in the selection 

 and location of crops and in deciding upon the time of planting is explained. 



Climatology of Italy in its relation with health and with, agriculture, 

 preceded by a study of climatic factors in general, G. Roster {CUniutologia 

 del]' Italia netle sue Attinenzc con Vlgiene e con VAgricoltwa Preceduta da una 

 Studio sui Fattori Climatici in Gencre. Turin, 1909, pp. XXIX+IO4O, pis. 13, 

 flgs. 68; rev. in Agr. Colon. [If alp], // {1910), No. 1, pp. 35, 36).— This is an 

 elaborate treatise dealing in an exhaustive way with the general climatic and 

 meteorological conditions in different parts of the earth, but especially as ob- 

 served in their various relations in Italy as a whole and in the different main- 

 laud and insular divisions of that country. 



An appendix treats of the climatology of the Italian colony at Eritrea, 

 Africa. The data regarding air, soil, and water, which are presented in great 

 detail, are correlated with economic conditions such as health and disease, 

 distribution of population, vegetation, and methods of culture. 



Compensation between types of simultaneous seasons in different regions 

 of the earth, II. II. Hildeurandsson {K. I8i-enska Vetensk. Akad. 11 audi., //5 

 (1909), No. 2, pp. 11, pis. ^).— In previous papers (E. S. R.. 22, p. 615) the 

 author has shown a certain climatic compensation between diffei-ent regions of 

 the earth and a correlation between the condition of the arctic ice and the 

 following season in parts of northern Europe. 



The present paper jM-esents a study of meteorological conditions at i)oints on 

 tne east coast of North America and in northern Siberia which shows that 

 conditions, for example at North Cape, furnish a basis for ])rediction of subse- 

 quent conditions in Iceland, the west coast of Greenland, and Newfoundland, 

 and that the sununer temi)erature at North Cape is in opposition to that which 

 may be expected on the Con/ment of Europe the following spring. 



Dependence of some geographical factors on the barometric relief of the 

 earth's surface, P. I. Brounov {Separate from Trudui Obshch. Zeml. Imp. St. 

 Peterb. Univ., vol. 2; abs. in Zhur. Opuitn. Agron. {Russ. Jour. Expt. Landw.), 

 10 {1909), No. .'/, pp. 599, 600). — A direct relation between atmositheric pressure
