526 EXPERIMENT STATION EECORD. [Vol.38 



A marked residual effect of the discharge upon the clover and grass following 

 the oat crop of 101 f) was observed and is to receive further study. 



Aerial electrical discharge and increased yields {Compt. Rend. Acad. Agr. 

 France, 3 (1917), No. 37, pp. 105.'i-10G2).—\ brief review and general (liscu.s- 

 sion of the experiment:il results noted above. 



Electro-culture (Elect. Rev., 81 (1917), No. 2067, pp. 21-23, figs. 5).— This 

 briefly reviews experimental work in electro-cxdture as noted above. Electro- 

 culture apparatus suitable for areas of from 10 to 15 acres is described and 

 illustrated.

 Poli^ Gubernskago Zcmstva. Chast I: Roc^h, Pshenitfua, Oves, Proso i Kukurnza. 

 Voronezh: Rosenberg Bros., 1915, pp. VIl-\-37). — Directions are given for the 

 time and method of making observations on the vegetative growth of cereals in 

 the field and laboratory, and blank forms illustrated for use in recording such 

 observations with rye, wheat, oats, millet, and corn. 



Xenia and other influences following fertilization, A. E. Waller (Ohio 

 Jour. ScL, 17 (1917), No. 8, pp. 27S-28Jt). — The author discusses in some detail 

 the phenomenon of xenia or " hybridization exposed," as he terms it, with special 

 reference to the distinction between the changes occurring in the endosperm 

 through triple fusion, thus directly associated with fertilization, and those 

 changes which follow fertilization but are remote from it. It is pointed out that 

 the xeniophyte, like the sporopliyte, is a fusion product, the egg nucleus of the 

 iatter fusing with one male nucleus, while in the former the second male nucleus 

 and the definitive nucleus fuse. The definitive nucleus forms upon the fusion 

 of two nuclei from opposite poles of the female gametophyte, the fusion nuclei 

 appearing after three successive divisions of the megaspore nucleus, during which 

 the egg is differentiated. 



The author suggests the term " ectogony " as a proper designation of those 

 influences which follow fertilization and are due to tlie developing zygote. In 

 xenia variation is said to appear as a direct result of the introduction of heredi- 

 tary factors. 



A brief bibliography is appended. 



Report of the department of agriculture, Barbados, 1915—16, J. R. Bovell 

 (Rpt. Dept. Agr. Barbados, 1915-16, pp. 2-29). — Experimental work with seed- 

 ling canes noted more fully in a previous report (E. S. R., 3-5, p. 134), cotton 

 experiments to improve the quality and increa.se the quantity of lint from 

 varieties of Sea Island cotton grown in Barbados, variety tests with cassava, 

 economic Caladiums, economic Xanthosomas, and yams, and field tests with 

 leguminous crops and fodder grasses have been continued. Tabulated data are 

 given briefly describing the cotton selections and hybrids grown on the experi- 

 mental plats of the Barbados department of agriculture and on the cooperative 

 plats, and showing the market classification and value of the cotton selections 

 grown on all plats in 1915-16. 



[Field crops], J. Mackenna (Rpt. Prog. Agr. India, 1915-16, pp. lS-31, 39- 

 43, Jf-'i, Ji5). — A brief outline is submitted of progress in experimental work 

 with wheat, rice, cotton, sugar cane, jute, indigo, tobacco, oil seeds, and fodder 

 crops conducted at various experimental centers in India during 1915-16. The 

 work included field tests of cultural methods and crop improvement througli 

 selection and hybridization.
