ter, N. Y., Feb. 1, 1892. 
.An article prepared by a committee of the Western New York Horticultural Society, con¬ 
sisting mainly of an abstract of a paper by D. G. Fairchild. Reference is made to the pres¬ 
ence of copper in many articles of common use as well as in sprayed grapes. Analyses 
show the maximum amount of copper to be | of a grain per pound of fruit. A summary of 
analyses made by Van Slyke is given, and the conclusion positively announced that it is 
impossible for a" person to get enough copper from the fruit to be injurious to health.

Abstract of paper read before Western New York Horticultural Society, advocating use 
of Bordeaux mixture and aminoniacal solution of copper carbonate, and suggesting a reduc¬ 
tion in amount of copper used in Bordeaux mixture, using 65 to 75 gallons of water [instead 
of 45] to 6 pounds of copper sulphate and 4 pounds of lime. (See Gard. and Forest, vol. v,

Refers to early belief as to the origin of blights or mildews, and to the later investigations 
as to their causes. These were carried on especially by the Section of Vegetable Pathology 
established in 1885, and as a result the scientific farmer is able to conquer diseases which pre¬ 
viously had wrought great havoc among his crops. (J. F. J.)

Recommends aminoniacal solution of copper carbonate in proportions of 5 ounces copper 
carbonate, 3 pints aqua ammonia, and 45 gallons of water. Details given as to method oi-ap- 
plying fungicide and a recipe for making copper carbonate at home at expense of about 18

Gives details of experiments on grape diseases to determine the comparative value of 
various fungicides; the value of mixed treatment and value of early as compared with late 
sprayings. The conclusions were that Bordeaux mixture heads the list as a preventive 
against black rot; copper carbonate in suspension and milk of lime are comparatively use¬ 
less ; copper acetate is liable to injure the foliage, as is also mixture No. 5. Early sprayings 
are absolutely necessary to insure the best results. (J. F. J.) (For Parts I and li see Nos. 
824 and 825.)
