[The transmission of sugars by pumpkins], L. G. Michael, S. A. Beach, 

 and E. E. Little {loiva State Col. A<ji: Rpt. 1907-8, p. l-'il). — A sinnmary is 

 given of a joint study made by the chemical and horticultural sections. 



The authors conclude that " The characteristic of tending toward a high 

 sugar content is variably transmissible and not so constant as the tending 

 toward a low sugar content. That is. an appreciable percentage of offspring 

 fi'om a high sugar pumpkin will contain a low percentage of sugar; while the 

 offspring from a medium sugar pumpkin seldom show a high sugar content 

 and the offsjiring from a low never show a high sugar content and seldom even 

 a medium sugar content."

On parthenocarpie of fruit trees. A. S. Doktorovicii-Ghrernitzkii {Trudui 

 Byuro PrJkl. Bot., 2 {1909), No. J,, pp. 20J-2.50, pis. .',, flgs. 6).— A review of 

 our present knowledge on this sub.iect, together with an account of exi^eriments 

 recently conducted by the author in which he demonstrated in an experimental 

 way that seedless apples can be produced through the castration of the blos- 

 som by the apple-blossom weevil {Anthonomns pomorum). In carrying on this 

 work one of the experimental trees was divided in two parts by sawing down 

 from the crotch through the root stock, one-half of the tree being used as a 

 control for the. other half. The seedless apples were somewhat smaller and 

 more irregular in form than the normal ai^iiles. 



The economic status of German fruit culture, A. .Janson {[''Hilling's Landiv. 

 Ztg., 58 {1909), No. 12, pp. 'i-i'1-'i50). — A general discussion of "the factors influ- 

 encing the conunercial development of the fruit industry in Germany. 



Although Germany imports annually large quantities of fruit and fruit 

 products, it appears that that country ranks second to the United States in the 

 number of fruit trees, and next to Switzerland in the number of trees in pro- 

 fiortion to her population. The author attributes the lack of development of 

 the native fruit industry principally to inadequate transportation facilities 

 and poorl.v regulated freight rates.

 100 varieties of edible fruits in Salvador, including notes on their principal
