Hastened energy, a new theory, J. H. Watkins {Proc. Ga. Hort. 

 8oc. 18!J3, 2>P- (>2-<)ii). — This paptT deals with experiments conducted to 

 ascertain the effect of planting immature or prematurely rii)ened fruit 

 seeds. Peaches were chiefly employed in the experiment. It was found 

 that seeds planted from hastily ripened fruit possessed a low degree of 

 vitality and a large ])ercentage would not germinate. Such seedlings 

 as grew produced fruit much earlier thau did the parent tree, and iu 

 many cases of improved quality. 



Field experiments with fertilizers on peach trees {'N'ew Jersey 

 IStas. Rpt. 18!J3, pp. 138-143). — Notes on a continued expeiimcnt begun 

 in 1884 on a private farm. Potash, either alone or in combination, has 

 given the best results, while nitrate of soda appears to have exerted 

 an unfavorable influence, except when used in connection with super- 

 phosphates. 



ISTotes are also given for an experiment just commenced on another 

 farm to test the effect of overfertilizing fruit trees, and the effect of 

 nitrogen and phosphoric acid supplied in dilferent ways, in one case 

 by means of nitrate of soda and boneblack, and in another by ground 

 bone and ground fish. In both cases potash is given as muriate of 

 potash. On each of the fertilized plats the yield in 181)3 was more thau 

 on an unfertilized plat. 



Soil tests ^vith fertilizers used on peach trees, A. T. Nbale 

 {Delaware Sta. Rpt. 1893, pp. 13-l(i). — Notes and tables showing tlie 

 results of ex[^eriments conducted on 2 private farms to ascertain the 

 value of the several soils and the fertilizers required by each. Both 

 nitrogenous and potash fertilizers gave favorable results, but the best 

 returns were found when the two styles of fertilizers were combined. 

 Crim.son clover is regarded as a valuable fertilizer. Mountain Kose, 

 Crawfoid Earl}^, and Foster were the varieties of peaches used in the 

 test, which has been conducted 3 years and is to be continued. 



Orchard fruits, C. n. Siiinn {CaUf>ivnia Sta. Rpt 1893 and 18!} J ^ pp. 

 361-373). — Notes on the orchard work conducted at the California Foot- 

 hill Station at Jackson, An:ador County. This comprises comparative 

 and cultural notes on the various varieties of apjjles, almonds, apricots,
