itself. Indeed, since it is propagated from one year to another through 

 the infection of the young leaves by those of the preceding year which 

 remain on the trees, all that is required is to pick off these diseased leaves 

 during the winter and burn them on the spot. 



This parasite either destroys the fruit altogether or leaves it quite 

 deformed, with only one side of the pulp developed, and therefore useless. 

 M. Corboz has observed that this disease is especially prevalent in wet 

 seasons in low-lying and sheltered orchards, where the trees are planted 

 too close together, and the branches are too low. On the other hand, 

 this disease rarely appears on isolated Cherry trees situated in the open. 



Cherry Orchards of Sollie Pont in the Var. Anon. (Le Jard. 

 July 20, 1902, p. 214). — An account of these is given. The kind chiefly 

 cultivated is a small black variety called the ' Spanish Cherry.' Of these 

 in the season, about the end of May, about thirty tons a day are sent off 

 by railway to the North. — C. W. D. 



Chimaphila maculata. By F. W. Burbidge {Gard. Chron. 

 No. 827, p. 318, fig. 106 ; Nov. 1, 1902).— A little North American plant 

 described as " A delightful little sub-shrubby Pyrola, not often seen, but 

 a delightful plant for the bog-garden. Like most of the Ericaceous plants, 

 it hates lime. In general appearance the plant looks like a Pyrola trying 

 to become an Arbutus ; the greyish leaves, crimson-red scapes, and droop- 

 ing white flowers are very beautiful." — G. S. S. 



Chinch Bug. By H. Garman, (U.S.A. Exp. Stn. Kentucky, Bep. 

 1898 ; 10 figs). — This insect (Blissus leucoptcrus) does great damage to 

 wheat in parts of America. Its appearance and habits are described, and 

 full notes on the fungal diseases which attack it are given. The fungus 

 Sporotrichum globulifcrum is cultivated and chinch bugs are infected 

 with it ; this results in a great diminution of their numbers. Notes on 

 the bibliography of the insect are appended. — F. J. C. 



Chondrobollea x Froebeliana. By E. A. Rolfe (Orch. Rev. p. 347, 

 Nov. 1902). — Interesting facts in connection with this distinct natural 

 hybrid, supposed to have its origin through the intercrossing of Bollea 

 ccelestis and Chondrorhyncha Chestertoni. — H. J. C. 



Chrysanthemums, Early, The Best. By C. H. Curtis (Gard. Mag. 

 No. 2558, p. 728 ; 8/11/1902).— In this number (devoted chiefly to the 

 Chrysanthemum) the writer gives a descriptive list of the best twenty- 

 five early-flowering varieties. The list has evidently been carefully com- 

 piled, and will be useful from which to make a selection of these beautiful 

 autumn flowers, so valuable in the open air in September and October.

Chrysanthemums, Grafted. By Albert Maumene (Le Jard. Nov.

 colours on the same bush, with notes on the practice. — C. W. D.
