uiany. The present volume coutaius color i)lates of 41 varieties of apples, each 

 plate being accoiupauied by a detailed description of the ti'ee and fruit and 

 information relative to its adaptability to soil and climate, productivity, ripen- 

 ing period, etc. 



On the breeding of wine grapes, Dern (Bcitr. Pflunzcnzucht, No. 4 (1914), 

 pp. 37-57). — In this paj)er the author shows in a general way what has been 

 accomplished in the iiiii)r()vemeut of wine grapes by means of selection alone, 

 points out many difficulties which will be met in the attempt to improve grapes 

 by breeding, and outlines some of the principal points which tlie breeder should 

 have in mind in improving wine grapes. 



The effects of frost on grafted vines in the Vaudois vineyards, H. Faes 

 and F. 1'orchet (Prog. Afjr. et. Vit. {Ed. VEst-Centrc). 35 {1914), No. 13, pp. 

 391-397). — In order to obtain some light on the opinion expressed in many 

 sections that European grapes grafted on American vines are more resistant to 

 frost conditions, the authors made observations on a number of varieties, both 

 grafted and ungraftcd, in Vaudois vineyards after the spring frosts in 1013. 

 From the data secured they conclude that the seeming superiority of the grafted 

 vines is due to their young age as compared with the ungrafted vines rather 

 than to any greater natural resistance to frost. 



On the grafting of wine grapes, J. Bernatsky {Jahresber. Vcr. Angeiv. Bot., 

 11 {1913), pt. 1, pp. 60-79).— The author here calls attention to the failures 

 which have frequently resulted in the attempt to reconstitute European vine- 

 yards by grafting on American stocks and discusses in detail the selection of 

 stocks and scions, the principles of grafting, nursery pi-actices, and planting 

 operations with sjiecial reference to the successi^il reconstitution of vineyards. 



Report on the wine and fruit industries of Argentina, Mackie {Diplo. and 

 Cons. Rpts. iLondon], Misc. Sen, No. 687 {1914), pp. 22). — A general survey of 

 the wine and fruit industries of Argentina, prepared under the direction of the 

 British consular service. 



A resume of investigations on the genus Rubus, B. Liuforss {Ztschr. 

 Induktive Abstain, u. Vcrerbunyslehre, 12 {1914), No. 1, pp. 1-13). — This com- 

 prises a posthumous manuscript by the author and here presented by W. 

 Johannsen dealing with his hybridization experiments with the genus Rubus, 



[Strawberries and tomatoes at Wisley, 1913] {Jour. Roy. Hart. 8oc. 

 [London], 39 {1913), No. 2, pp. 401-414)- — Descriptive notes are given on 76 

 varieties of strawberries and some 90 varieties of tomatoes tested at the Wisley 

 Gardens in 1913. 



Tropical and subtropical fruits in California, F. W. Popenoe {Jour. Roy. 

 Bort. Soc. [Lmulon], 39 {1913), No. 2, pp. 330-337, pis. 5).— This comprises 

 horticultural notes on those tropical and subtropical fruits in California 

 which have become so well established as to be offered by the trade. An addi- 

 tional list is given of fruits and plants many of which have not as yet passed 

 beyond the experimental stage. 



The atemoya, a new fruit for the Tropics, P. J. Wester {Philippine Agr. 

 Rev. [English Ed.], 7 {1014), No. 2, pp. 70-72, pi. 1).—As a result of his polli- 

 nation experiments with Annouas (E. S. R., 24, p. 341) the author secured a 

 number of hybrid forms one of which, a cross between the sugar apple {Annona 

 squamosa) and the cherimoya {A. cherimola), has fruited for the first time. 

 This fruit, which has been given the name atemoya, is practically identical 

 with the prominent carpelled cherimoyas and appears to combine to a certain 

 degree the adaptability of the sugar apple to grow well in low altitudes near the 

 equator with the excellent flavor of the subtropical cherimoya which does not 

 succeed well iu such situations.
