list of apples with references to figures appearing in publications of various 

 countries. 



The peach in New York {islexv York State Sta. Circ. 15, pp. 8). — A popular 

 circular discussing location and soil, fertilizers for peaches, moisture require- 

 ments, cultivation, hardiness, the priucipal diseases, pruning, cover crops, and 

 thinning the fruit. 



From the station's collection of over 300 varieties of peaches, a list is here 

 given of 23 varieties, grouped in periods of ripening, which are considered most 

 worthy of planting in commercial orchards. 



Self-sterility in plums, W. Backhouse (Gard. Chron.. 3. set:, 50 (1911), 

 No. 1296, p. 299). — The results thus far secured from pollination experiments, 

 started in 1910, with ordinary European plums show that the varieties fall into 

 2 sharply defined groups, self -fertile and self-sterile, just as do the Japanese 

 and American plums. The author suggests that the " June drop " of American 

 plums as well as the early " stoning " of Greengages and cherries may result 

 from self-pollination. 



Small fruits: Management and varieties (Neiv York State Sta. Circ. lit, pp. 

 8). — This contains popular suggestions relative to the management of a small 

 fruit plantation, attention being given to the location and exposure of the plan- 

 tation, tillage, fertilizers, planting distances, pruning, protection of plants, and 

 selection of varieties. 



Lists of strawberries, raspberries, currants, and gooseberries, including many 

 standard kinds and some of the newer varieties considered worthy of more ex- 

 tended trial, are given. 



On some effects of drought with special reference to pruning grapevines, 

 L. Ravaz and G. Verge (Prog. Agr. ct Tit. {Ed. VEst-Centre), 32 (1911), Xo. 

 47, pp. 602-608) .—Growth, yield, and vintage data, together with data on 

 moisture evaporation from the bunches, leaves, and shoots of grapes lead the 

 authors to conclude that the sensitiveness of the vine to drought is dependent on 

 the number of bunches of grapes on each vine. On dry situations reduction in 

 number and length of the canes is recommended, as well as wider planting dis- 

 tances, suitable plowing, and removal of soil from the base of the vines to per- 

 mit the penetration of rain water to the subsoil. 



As compared with the leaves the evaporating power of the bunches is very 

 slight. Intiict bunches do not directly absorb either rain or irrigation water. 



Bleaching walnuts with an electrolyzed solution of salt, L. J. Stabler 

 (Cal. Fruit Grower, .'/// (1911), Xo. 1221, p. 5, flgs. 2). — The process described 

 consists in subjecting walnuts to the action upon the shells of an electrolyzed 

 solution of salt. The salt solution is applied to the shells by spraying or dipping 

 the walnuts in the liquid and allowing it to dry upon them. The electrolyzing 

 apparatus is illustrated. 



Lily-of-the-valley culture and fertilizer experiments in Tannenhof, F. 

 Stoffert (Moller's Deut. Gcirt. Ztg., 26 (1911), Kos. 39, pp. -',58-463; JfO, pp. 

 Ji74~'i~6, figs. 12). — ^The author describes improved methods of growing lily-of- 

 the-valley pips and gives the results of fertilizer experiments conducted since 

 1907. He finds that contrary to a common opinion commercial fertilizers 

 exert no injurious influence on the forcing quality of the pips nor upon their 

 adaptability for cold storage. A complete fertilizer containing a sufficiency 

 of all the elements produces pips which force out quickly and vigorously. 



The herb garden, Frances A. Bardswell {London, 1911, pp. VIII-\-n3, pis. 

 16). — This is a popular English work containing cultural directions, together 

 with information relative to the uses of different herbs, gathering, drying, 

 and storing.
