Blackberry Culture. By H. D. {Jour. Hort. p. 332; Octo- 

 ber 10). — Instructions are given, and its more general use advised.

Black Currant Mite {Wohum %id Bep. 1900, p. 7).— Experiments 

 on removing buds, cutting down and removing busbes, showing the 

 liability to attack of different varieties. Spraying with various strengths 

 of carbolic acid, calcium sulphide, petroleum, antinonnin, none of which 

 spraying is recommended. Painting with turpentine, methylated spirits, 

 naphtha, solution of naphthaline in naphtha form, aldehyde, petroleum 

 emulsions ; treatment with hot water, at different temperatures for 

 different lengths of time. The difficulty is to kill mites and eggs^ 

 without injuring the plant. It is considered that cutting down the bush 

 to ground-line and removing roots to unaffected surroundings gets rid 

 of the mite, when new sprouts are produced. — C. H. H. 



Bletia hyacinthina, R. Br. (Cogniaux in Diet. Icon. Orch.y 

 Bletia, pi. 1 ; 11 1901.) — A native of China, Cochin China, introduced 

 in 1803. Flowers lilac to crimson. — C. C. H. 



Bouquets, Japanese. By G. B. {Rev. Hort. pp. 431-34 ; September 

 1901). — Five woodcuts. Illustrating and describing some very quaint 

 treatments of plants and branches for bouquet purposes, or rather indoor 

 decoration in pots and vases. — C. T. D. 



Brown Rot. ' Sur une epidemie de Rot Brun aux environs de Paris.' 

 By M. Mane Molliard (Ball. Soc. Myc. Fr. xvii. p. 280 ; 1901).— This mould, 

 which is known as Monilia fnictigena in Britain and North America, 

 chiefly attacks the ripe fruit of Pear, Apple, Cherry, &c. ; but in the out- 

 break here recorded it attacked Apricots principally, and not only fruit but 

 the foliage, twigs, and flowers, producing gummosis in the cicatrices of 

 the fallen leaves, causing great damage. In substantiation of this state- 

 ment healthy plants were inoculated by the aid of pure cultures of 

 Monilia fnictigena, which resulted in the production of the disease. It 

 is recommended that in the spring sulphate of copper solutions should be 

 used freely. — M. C. C. 



Brown Spot of Apple. By Prof. C. 0. Townsend {U.S.A. Hort. 



Soc. Maryland, 1900, with cuts). — In the early stages of the disease 

 the surface of the fruit appears perfectly normal, but as the disease 

 advances sunken spots appear scattered irregularly over the surface. 

 When cut the flesh is found to be filled with brown spots, scattered 

 irregularly from core to surface. The spots are variable in size, 

 irregular and indistinct in outline, while their texture is somewhat tough 

 and spongy. These spots are found to be filled with a thread fungus, 

 which is responsible for the spots. The sunken spots of the surface 

 become more marked and darker than the surrounding epidermis. The 

 brown spots increase in size until the whole interior becomes affected, 

 and begins to shrink, causing the surface to become rough. In the 

 last stage the fungus forms small cavities in the epidermis, in which 

 the spores are produced. No opportunity has yet been found for applying 

 a remedy. — M. C. C.
