trees with a solution composed of copper sulphate 4 lbs., alum 2 lbs., lime 3 lbs., and 

 water 30 gals. Directions for the preparation and api)lication of this fungicide are 

 given. 



Some diseases of coflfee, A. L. Heukeka {Com. J'ctmxit. ^l(jr. [Mcrico], ('Ire 1, j>p. 

 S, Jig. 1). — Notes are given on the diseases of coffee caused by StiUmm ffdridmn and 

 S})}i:rrell(i coffeicola, the former of which is said to cause great damage to coffee plan- 

 tations. The thorough use of Bordeaux mixture is reconmiended as a preventive 

 measure, and extensive experiments are l)eing inaugiu'ated to thoroughly test the 

 elticiency of this treatment. 



The use of copper fungicides and the quality of the copper sulphate ( CIi ron. 

 Ai/r. ('anion Vand, IH {1903), Xo. 21, pp. 597-599). — Attention is called to the great 

 variation in the quality of the copper sulphate supplied by the markets in 1903 and 

 the consequent variation of the results obtained when applications were made for 

 the control of fungus diseases. In order to secure the best results, it is claimed that 

 some attention should be paid to the quality of the chemicals used and that a Federal 

 contr(.)l should be established for the guaranty of the purity of such products.

 by E. A. Schwarz. 



In the last-nametl paper the author reports his experience in studying the cotton- 

 boll weevil in Cuba. First it was suspected that this insect might have some native 

 food plants other than cotton. It was impossible, however, to find the weevil upon 

 any plants except cotton. It was found feeding upon "loose cotton" {Gossypium 

 brasilifnse), and upon "kidney cotton." The weevil is not especially common ui)on 

 or injurious to either one of these species, but the evidence obtained by the author 

 indicates that the "kidney cotton" is the original food plant of the cotton-ljoll weevil, 

 and tlie author believes that this insect has no other food plant than species of cotton. 

 No parasites of the cotton-boll weevil were found in Cuba. 



Report of the entomologist, G. W. Herrick {Ml.'fsis.vippI Sta. llpt. 19o.i, pp. 24, 

 25). — Brief notes on insects injurious to pecans, peach-tree borer, Colorado jwtato 

 beetle, harlecpiin cabbage bug, San Jose scale, pine-leaf beetle, fall webworm, and 

 chicken mite. 



Entomology, C. W. Woodworth {California Sta. lipt. 190i^-:l, pp. 104-110). — A 

 brief re\iew is given of the entomological work of the station for the period 1901-3. 

 Ab.stracts are given of the bulletins published during this time. Si)ecial attention is 

 called to the work in coudjating grasshoi)i)ers and red spiders, in studying the sub- 

 jects of ])each-tree borers, fumigation, California distillates, etc., ami moscjuitoes.
