Grafting- of Seedling's by Approach. By Max Gamier {Rev.j 

 Hort., August 1, 1911, p. 347-8; one woodcut). — Description of a pro-j 

 cess by which young seedlings of Eoses and many other plants can be | 

 grafted on stocks in such a way as to secure much more rapid develop- j 

 ment and flowering than by the ordinary methods of budding or grafting, j 

 The young plant together with its roots and a little soil is wrapped in a ^ 

 piece of coarSe cloth tied with raphia after the upper part of the stem! 

 has been closely applied to the stock, leaving the terminal bud exposed.) 

 Careful watering enables the roots to assist development of the scion, 

 whicli speedily unites with the stock and then rapidly develops. Thej 

 illustration shows the roots removed and a projecting stem inserted; 

 into a glass vessel filled with water and suspended from the stock, 

 the upper part of the stem being applied to the stock as above. The 

 letterpress, however, advocates the detention of the roots as described. 

 Eoses are stated to produce full-sized flowers very shortly after the 

 graft is perfected. Fruit trees are equally assisted by the same method.

Grape, Ascogenous form of Fung-us causing" ** Dead-arm " of.' 



By C. L. Shear {Phytopathology, I, 4, pp. 116-119 ; Aug. 1911; figs.)., 

 — This disease is due to the fungus Fusicoccum viticolum Eeddick 

 (U.S.A. Exp. Stn. Cornell, Bull. 263, 331). The present communi- 

 cation records the discovery of the higher form of the fungus, the 

 spores of which were found to produce the Fusicoccum form in pure 

 culture. The higher (ascogenous) form of the fungus is named Crypto-^ 

 sporella viticola Shear, and a description and figures are given. — F. J. C 



Grease Bands. By A. Wernicke (Oester. Gart. Zeit. vol. vi 

 pt. 3, pp. 102-105). — Grease bands not only capture the codling anr.

 weevils. The bands should be smeared in spring as well as in autumnj 

 and the trees shaken early in the morning in spring. — S. E.W. I 



Gumming" of Stone Fruit Trees. By E. Frantz (Gartenflorai 

 vol. Ix. pt. 4, pp. 82-83). — The application of half a pound of com

 gumming in peaches, and also in plums and cherries, — S. E. W . j
