Rep’ts from the consuls of U. S., No. 128, Washington, May, 1891, pp. 34-41. 
Refers (p. 34) to instructions given by Prof. Ferrari, of the Royal Technical 
Institute, to the soldiers of the farming class on the following subjects: 
(1) Peronospora, its character, development, damages, and remedies. (2) 
Treatment and method of applying sulphate of copper. (3) Phylloxera, its 
character and how to prevent its spread. Over 200 soldiers have attended 
the lectures, and great interest was manifested. (J. F. J.)

vol. 9, No. 210, London, Jan. 3,1891, p. 23, one-third col. Mentions a patented 
fungicide containing sulphur, sulphate of copper, and lime in the form of 
powder, for use against the Peronospora of the vine. (M. B. W.)

Oct., 1891, p. 266,1 col. Gives extract of paper read before the Society for the 
Promotion of Agricultural Science, Aug., 1891, Washington, D. C. Records 
results of experiments in Virginia in 1891, with following fungicides as pre¬ 
ventives of black rot of the grape: Ammoniacal copper carbonate solution, 
modified eau celeste, precipitated carbonate of copper solution, copper sac- 
charate, copper carbonate and glue mixture, Bordeaux mixture, copper ace¬ 
tate, and copper chloride mixture. Each of tbe above fungicides contained 
approximately the same amount of copper as the ammoniacal solution, 0.1 oz. 
per gallon of water. Reports results of the copper mixture as increasing the 
yield of perfect fruit from 20 to 50 per cent, while use of several non-cupric 
mixtures (potassium sulphide, sodium hyposulphite) gave increase of 20 to 
38 per cent. Adds result on experiment with full and half strength of Bor¬ 
deaux mixture, concluding the two mixtures to stand in relation of 96: 86 in 
effectiveness. Reports experiment, with pear leaf-blight and scab with same 
fungicides, in which the copper mixtures apparently slightly injured fruit 
and foliage. (D. G. F.) 
468. Galloway, B. T. Fungous diseases of the grape and their treatment. Farmers’ Bull.,

swers numerous queries of audience. (D. G. F.)

ment of grapes for black rot and pear seedlings for leaf-blight. Refers to

apparatus, with instructions as to best methods. Quotes “Yellows” law of
