or from close proximity to timber (as is often seen in English fields near 

 the hedgerows). Several methods of improvement are suggested, amongst 

 others terracing (to prevent soil-washing), autumn ploughing (turning in a 

 green crop at the same time), surface cultivation, as being better for this 

 particular plant than deep ploughing, but frequent enough to check weeds 

 and maintain a loose soil mulch of two or three inches ; planting an 

 enriching leguminous crop between rows of Corn in poor soil &c. 



Illustrations of useful and necessary machinery are given. — C. II. C.

Corynocarpus (Forst), On the Genus. Supplementary Note. 



By W. Botting Hemsley (Ann. Bot. xviii. Jan. 1904, pp. 179-180).— This 

 is merely a supplementary note to tho author's paper on the genus (Ann. 

 Bot. xvii. 1903, p. 743). The note has reference to a paper on Coryno- 

 carpus by Van Tieghem. — A. D. C. 



Cotoneaster angustifolia. By M. T. M. (Gard. Chron. No. <);;9, 

 p. 441, fig. 191 ; Dec. 24, 1904). — This plant is one of the many fine 

 things that have been found in the Chinese province of Yunnan. It has 

 been in cultivation at Kew since 1899, but it does not seem to have 

 attracted much, if any, attention until a spray densely covered with its 

 yellow fruit was exhibited at one of the recent fortnightly shows of the 

 Royal Horticultural Society. It was shown by Messrs. Paul and Son on 

 behalf of M. Maurice de Vilmorin. The seeds from which tho plants 

 were grown were obtained from Eastern Tibet, where apparently this 

 species is subject to severe frost, so that it should be quite hardy. 

 M. Vilmorin says : " The young plants are for the first three to four years 

 erect, but then the lateral branches begin to take much development, and 

 the two bushes at Les Barres, left entirely unpruned, are of similar habit, 

 that is, about 4 feet high and (i feet wide, with the branches mostly 

 horizontal, the lowest trailing on the ground." — G. S. S. 



Cotoneasters. By W. T. (Gard, May. 2067, p. 810 ; 10/2/04).— An 

 excellent descriptive account of the species of Cotoneaster in cultivation 

 by a writer whose knowledge of them is evidently intimate. 



The species include the new C. angusti/olia from China, and intro- 

 duced by M. M. de Vilmorin, of Paris. 



An excellent illustration of a fruiting branch of this novelty is given 

 with the article. — W. G. 



Cotton-boll Weevil, The Mexican [Anthonomus grandis Boh.). 

 By W. D. Hunter and W. E. Hinds (U.S.A. Vep. Agr. Div. Ent., 

 Bull. 45). — This insect " has the unique record of developing in less than 

 twenty years from a most obscure species to undoubtedly one of the most 

 important economically in the world." The female, with the aid of her pro- 

 boscis, makes a hole towards the lower part of the calyx, within which she 

 deposits an egg, either just inside the base of a petal or among the lowest 

 anthers. Within a few days the eggs hatch, the young grubs feed and
