.Effects of grafting; specific reciprocal influence of scion and stock in 

 grapes, ].. R.waz {Proy. A(jr. et Vlf. {Ed. L'Exl), .'4 {190.3), To.s. Jh', pp. 4'jo-o(i4, 

 Jifj. I : J7, pp. ~>14-iJ20, flip. 2). — This pai)er, which was read at the International 

 Congress of Agriculture at Rome, in 1903, is al.so pul)lished as a separate. Experi- 

 ments with a large number of species and varieties of grapes indicate that cuttings 

 made from Vinifera grapes grafted on American stocks are no more resistant to phyl- 

 loxera than cuttings grown on Vinifera stocks, and that the (juality of the Vinifera 

 fruit is not injured by grafting on American stocks for a jieriod of years; neither is 

 the (juality of the fruit of American vines improved by grafting on improve<l varieties 

 of Vinifera grapes. Notes are given on the modifications jiroducefl by grafting in the 

 region <if the callus, and on the infiuence of grafting on the nutrition of the vine. 



"Headlight," a new early grape of the Delaware group, S. A. Beacu {Amer. 

 Gard., 24 {1903), Xo. 442, p. 365). — The opinion of the author is given on a very 

 early red grape originated by T. A'. ^Nlunson in 1895. It has been grown at the 

 Geneva Station for 2 years and the author believes it to be of sutticient promise to 

 merit investigation as a very early grape. 



Home manufacture and use of unfermented grape juice, G. C. Hlsmann 

 {TJ. S. Dept. A(jr., Farmers' Bui. 175, p>p. 15, Jigtf. 8). — Popular directions are given 

 for the manufacture of unfermented grape juice in small and large (luantities. A few 

 recipes are given for a number of culinary u.ses of grape juice. 



The pests and blights of the tea plant, (t. Watt and H. H. ^Iaxn {Calcntla: 

 Supt. God. Priiding, 1903, })p. 4^9, ph. :.^4, _fif/K. 44)- — More than one-third of this 

 book is devoted to tea culture, including such matter as races of the tea plant; seed 

 gardens, and improvement of seed; hoeing, weeding, and tillage generally; drainage 

 of tea gardens; j)rinciples of j^runing; tea picking, and manuring; thus making the 

 book a very complete treatise on tea culture. The chapters on the insect pests and 

 the fungus diseases of the tea plant discuss these subjects very fully. Other animal 

 pests, such as spiders, mites, nematodes, worms, snails, slugs, millipedes, etc., are 

 also iliscussed. 



Caoutchouc and gutta-percha cultivated in the Dutch East Indies, P. Van 

 RoMBUKGH {Les pJantes a caoutchouc et a fjutta-percha cult'tvce>< oxx Jnde.^ Xi'crlanddises. 

 Batavid, Java: G. Kolff & Co., 1903, pj). 208, ph. 15, map 1) . — This is a report of an 

 exploring tri]) made with special reference to the caoutchouc and gutta-percha indus- 

 tries of the Dutch East Indies, more particularly the dissemination anrl culture of 

 these trees. Various species of caoutchouc and gutta-percha cultivated in the Dutch 

 East Indies are described, as are also the methods of producing these substances. 



The culture of walnuts in France, J. Artiiaid-Bkrthet {An)i. Inst. Nat. Agron., 

 2. ser., 2 {1903), Xo. l,pp. 19-144,. ti'J"- 8). — A treatise on walnut culture {.Turjluns rerjia) 

 in France. The work discusses the botany of walnuts grown in France, classification 

 of varieties, geographical distribution, climate best suited to this species, soils, 

 methods of propagivtion, culture, manuring, harvesting, and tlie econ(jmic impor- 

 tance of the walnut industry in France, etc. 



Shade trees and ornamental vines in Montana, .1. W. 1!lanki.\suii' {Montaiui

 that can l)e grown in different parts of Montana. 



Budding the lilac, L. Daniel {Compt. Rend. Acad. Sri. J'((rls, 137 {1903), Xo. 2, 

 pp. 143-145). — An account is given of some experiments in budding lilacs, in which 

 conclusions are drawn for all grafts as follows: (1) The relative affinity or difference 

 of functional capacities between stock and scion at different periods of the symbiosis 

 plays a very important role in the success, duration, and biology of all grafts. (2)
