equipment for drying, evaporation of various fruits by artifical heat, equipment 

 and details of sun drying, details as to the preparation of evaporated and dried ■ 

 fruits for market, insects injurious to dried fruits, and laws relating to evapo- 

 rated and dried fruits. 



Homemade fruit butters, C. P. Close (U. S. Dept. Agr., Farmers' Bui. 900 

 {1911). pp. 7). — This briefly discusses and gives directions for preparing a few 

 of the more common home products. 



Contribution to the study of the viscous fermentation of beet juice, H. 

 Delaval {Ann. Sci. Agron., 4. ser., 5 {1916), No. 7-9, pp. 323-336) .—The author 

 has studied the morphology, optimum conditions for growth, character of cul- 

 tures, metabolic products, effect of various influences on growth, and effect of 

 antiseptics on various microorganisms which are held responsible for viscous 

 fermentation. The condition is indicated as being rather difficult to control, and 

 the necessity of the complete sterilization of the utensils used in the fermenta- 

 tion is emphasized. 



Contribution to the study of alcoliolic fennentation, E. Kaysee {Ann. Sci. 

 Agron., 4. ser., 5 {1916), No. 1-9, pp. 297-3^2).— Experimental data obtained in 

 a study of the production of alcohol from various raw materials are submitted 

 and discussed. 



Field tests made on oil treatment of wood ag-ainst m.arine borers, C. H. 

 Teesdale and L. F. Shackell {Engin. News-Rec, 79 {1917), No. 18, pp. 833-837, 

 figs. 6). — This is an experimental study of the value of various preservatives 

 and methods of treatment. The results in general show that a proper creosote 

 oil for marine work should contain a large proportion of constituents boiling 

 above 320° C, as well as considerable amounts of high boiling tar acids and 

 bases. 



METEOROLOGY. 



Agricultural meteorology, J. W. Smith (Proc. 2. Pan Amer. Sci. Cong., 

 1915-16, vol. 2, pp. 75-92, figs. 5). — This article discusses what has been done 

 and what it is considered possible to do in the way of coordinating mete- 

 orological observations with agricultural production, outlining especially the 

 general program of the section of agricultural meteorology of the Weather 

 Bureau of the U. S. Department of Agriculture. Some of the possibili- 

 ties of this line of investigation are illustrated by results of studies made by 

 the author on the correlation between temperature and rainfall and yield of 

 corn and winter wheat and on the critical period for potatoes. 



The economic aspect of climatology, E. L. Wells {Proc. 2. Pan Amer. Sci. 

 Cong., 1915-16, vol. 2, pp. 2^0-2^9). — This article briefly discusses some of the 

 economic relations of climatology to agriculture, engineering, transportation, 

 commerce, manufacturing, health and efiiciency, recreation, and the like. A 

 short bibliography of the subject is added. 



Forecasts of weather favorable to an increase of forest fires, E. A. Beals 

 {Proc. 2. Pan Amer. Sci. Cong., 1915-16, vol. 2, pp. 257-270, figs. 8).— This 

 article discusses the damage caused by forest fires in the United States, de- 

 scribes the weather conditions most favorable for such fires, and makes a plea 

 for more extended study of such conditions with a view to improving the fore- 

 casts of wind as well as of other elements that cause an increase in the number 

 of forest fires. 



The meteorological influences of lakes, E. R. Miller {Proc. 2. Pan Amer. 

 Sci. Cong., 1915-16, vol. 2, pp. 189-198, figs. 9).—" The object of this paper is to 

 call attention to the relatively important effects of the land and sea breezes
