40 EXPERIMENT STATION RECORD. [Vol.43 



porinient Station, presenting tlie results of deterniinations of the moisture con 

 tent of fruit buds of two varieties of peaches during the winter of 1918-19. 

 The two varieties selected for this study were the Elberta and Greensboro, the 

 latter of which is considered more hardy with respect to winter injury. Bud.s 

 were selected from trees growing on high ground, on low ground, and from 

 trees receiving varied fertilizer treatment. The determinations were made at 

 monthly intervals beginning with November 8 and ending with March 7, a final 

 analysis being made on March 28. 



With few exceptions the amount of moisture in proportion to dry weight of 

 the Elberta fruit buds was gi'eater than that of the Greensboro buds. No 

 great differences were apparent between the ratio values of buds taken from 

 trees gi-owing on high ground and from those growing on low ground. There 

 was no uniformity of differences between trees receiving fertilizer treatments. 



There was a marked seasonal increase in the water content of the fruit buds 

 of both varieties, whether determinations from individual trees or from aver- 

 ages are considered. As the season advanced the difference between the water 

 content of the fruit buds of the two varieties became more marked, the values 

 for Elberta, the less hardy variety, being the greater. 



These results suggest further investigation to determine whether this varia- 

 tion in moisture content is a varietal characteristic, and to what extent such 

 moisture content values are related to hardiness of the fruit buds. A list is 

 given of cited literature dealing with studies relating to the resistance of 

 plants to low temperatures. 



Productive small fruit culture, F. C. Sears {Philadelphia and London: 

 J. B. Lippincott Co., 1920, pp. IX +368, pi. 1, figs. 196).— TMs is one of a series 

 of farm manuals edited by K. C. Davis. It treats in detail of the growing, 

 harvesting, and marketing of strawberries, raspberries, blackberries, currants, 

 gooseberries, and grapes. 



The resistance to drought of various graft-stocks, H. Sicard {Prog. Agr. 

 et Vitic. {Ed. V Est -Cent re). Jfl (1920), No. 11. pp. 256-262).— A contribution 

 from the Central Agricultural Society of Herault, comprising notes on the 

 drought resistance of a number of grape stocks. 



The author concludes that for the deep, strong, calciferous soils included 

 in the study the stocks best suited to resist a prolonged and intense drought 

 are the hybrids of Vinifera X Rupestris. These have shown a notable superi- 

 ority over pure American and America-American and even Vinifera XBer- 

 landieri stocks. 



The preservation of vines from spring frosts, L. Degrully {Prog. Agr. et 

 Yitic. {Ed. VEst-Centre), 4I {1920), No. 11, pp. 245-254, figs. 8).— A popular 

 discussion of diffei-ent methods used with more or less success in protecting 

 plants from spring frosts. 



[Report on fruit investigations], S. L. Ajrekar {Ann. Rpt. Dept. Agr. 

 Bombay, 1911-18, pp. 15, 76). — In continuation of a previous report by Burns 

 (E. S. R., 42, p. 736), brief notes are given on experimental work for the year 

 1917-18 with the mango, citrus fruits, guava, papaya, grape, fig, banana, and 

 other fruits. 



[Notes on bananas, citrus fruits, and spices] {Fiji Dept. Agr. Ann. Rpt. 

 1918. pp. Jf-6). — Notes are given on the life history of China and Gros Michel 

 banana plants planted in 1917, together with an outline of selection studies 

 to be conducted with the view of increasing the vitality of banana plants in 

 Fiji. Tests of various citrus fruits and spices are briefly noted. 



The cambuci (Paiviea langsdorffi), P. Campos Porto (O. Camhuci. Rio de 

 Janeiro: Jardim Bot., 1920, pp. 14, pi. 1, figs. 8).— A contribution from the 

 Botanical Garden of Rio de Janeiro describing a myrtaceous tree native to the
