than one-half of that necessarily taken with each pound of grapes, stems 
and all, sprayed as profusely as those analyzed. 
When it is considered that 203 vines received in one season’s treat¬ 
ment only 57.25 pounds of copper, or 4J ounces per vine, the very incon¬ 
siderable amount which remains adhereut to the berries is not to be 
wondered at. Although spraying after the middle of July with the 
Bordeaux mixture is to be avoided, it will be seen that there is no real 
danger arising therefrom, and when the ammoniacal solution is substi¬ 
tuted for the last three sprayings, since it contains only as much 
copper, there can be no possible danger. 
DISEASES OF THE GRAPE IN WESTERN NEW YORK. 
Numerous complaints having been received from correspondents in 
various parts of western New York of a disease which was seriously 
injuring grape vines, it was decided to send some one into the field to 
investigate the matter. Accordingly, on October IS, Mr. D. G. Fair- 
child was directed to visit Lockport, N. Y., and such other points 
within the State as might be necessary, and to obtain such information 
and make such investigations as would enable him, if possible, to de¬ 
termine the cause of the trouble and suggest a remedy therefor. Below 
is Mr. Fairchild’s report. 
B. T. Galloway, 
Chief of Division. 
Washington, D. C., October 25, 1890. 
Sir: In accordance with your instructions, I left Washington on 
October 18, proceeding directly to Lockport, N. Y., where, through 
the kindness of the Niagara White Grape Company, I was enabled to 
obtain much valuable information relative to the new disease of the 
grape, which is generally referred to under the name of u blight” or 
“ rust.” After leaving Lockport several important grape growing 
regions were visited, in all of which the new trouble was found more or 
less abundantly. I submit my report on the investigations made, and 
also add some notes on other vine diseases which came under my 
observation. 
Bespectfully,

Assistant.
