Notes on the truffle, E. Roulanger {Loiix-lc-Saiiiiin-: Litcirii Dcrlunic. IflOG, 

 pp. 16, pis. 4). — This pamphlet is made up of three ])apers presented before the 

 Societe Mycologique during the years lOO-t to 1!»U(J sui)plementing the author's 

 worlj previously noted (E. S. R., ir», p. 472). lu these articles various phase.s of 

 truffle culture and spore germination are considered. 



The best fruits for all sections, S. W. Fletcher et al. {Count nj Life Ainer., 

 9 (19116), \os. .-). pp. .J7i-.T7'/. ■198 ; 6. pp. 760. 762, 767/ ; JO (]!)fi6). .Yo. 1. pp. 100- 

 106). — A general discussion on the selection of fruits of l)igh qu-ility and ])Iant- 

 ing. with recommendations as to varieties of orchard, bush, and other small 

 fruits for each of the different States and Canada, the varieties suggested being 

 largely those recommended by the horticulturists of the experiment stations. 



Effects of stocks upon varieties, A. G. Gulley ( West. A'. Y. Hart. Soe. 

 Proc, .51 {1906), pp. 1-^-20). — Sweet Bough and Jersey Black varieties of apples 

 were used as stocks upon which Red Canada and Red Astrachan were worked. 

 No effect of the stocks upon the quality of the fruit could be detected. The use 

 of Northern Spy as a stock did not delay the fruiting period of Jonathan or 

 Red Canada worked upon it, showing again no visible influence of the stock on 

 the scions. 



Influence of bagging on the quality of fruit, M. Garnier (Rev. Hort. 

 [Paris], 78 (1906), No. 9, p. 208). — An account is given of some experiments 

 carried on by Messrs. Riviere and Bailhacheat the agronomic experiment station 

 at Versailles on the composition of fruits as aft"ected by bagging. Grapes and 

 pears were the fruits investigated. The analysis of the fruit thus produced 

 showed that the bagged grapes contained 205 gm. of sugar per liter of juice, 

 while in the fruit not bagged there were Init 198.5 gm. The acid content of the 

 fruit grown in tlie bags was 2.8G gm. per liter of .iuice, and in the open 3.08. 

 In the case of the pears, likewise, the total sugar content of the pulp in the 

 bagged fruit was greater than in the fi'uit grown in the open. The acid content 

 of the pears grown in the bags averaged 2.80 gm. per 1,000 parts of fresh pulp, 

 as compared with 1.75 gm. for fruit grown in the oi)en. 



Fertilizer experiments with grapes, E. Zachakewicz (Proci. Afjr. et Tit., 

 (Ed. FEst). 27 (1906)-, Ao.s. .'/, pp. 118-122; 6, pp. 17 1-17. 'i; 7, pp. 21.5-218).— 

 Numerous exi»eriments were made with fertilizers (»n different soils. Analyses 

 are given of the soils and details of the results secured. The general conclusions 

 drawn from the experiments are to the effect that nitrate of soda associated 

 with sulphate of potash and superphosphate of lime is a valuable fertilizer, 

 increasing the yields, hastening the maturity, and raising the sugar content 

 of the fruit. In order to obtain maxinunn results with this manure, the sul- 

 phate of potash and superphosphate of lime should be applied in the fall and 

 worked into the soil, the nitrate of soda being added the following spring in 

 March or April, and also worked in. 



The Gorz prune industry with special reference to sulphuring the fruit, 

 A. Devarda (ZtscJir. Lmnlir. Versndisir. Orsferr.. 9 ( 19(i6) . Xo. ',. pp. J,8.')-6.i9) . — 

 An account of the prune industry in the vicinity of Gorz with the result of stud- 

 ies of various factors in the process of manufacture with the idea of improvin,i; 

 the itroduct. Only well-ripened fruit^should be used for drying. The dried 

 product should not contain over 25 to 30 per cent of moisture. In sulphuring 

 the fruit not over 5 to G pounds should be used per hundred pounds of fruit, the 

 duration of the sulphuring to last 20 to 30 minutes. In rainy weather sulphur- 

 ing every 4 to 5 days is necessary. The time for each sulphuring under such 

 conditions should not exceed 15 minutes. When pleasant weather again returns ■■
