New York AGRICULTURAL EXPERIMENT STATION. 315 
_ Hardly a trace of the ammoniacal spraying appears on the fruit; 
very seldom is there a trace evident, and the most minute chemical 
analysis fails to show more than an indication of copper solution on 
fruit which had been sprayed, not sufficient to indicate by any of the 
almost infinitesmal signs used in such analyses. Jn this connection 
the following questions in effect were put to both Messrs. Fairchild 
and Moore, and answered as follows: 
Q. Would you advise the immediate spraying of an untreated vine- 
yard in which there was no appearance of the disease, with the 
ammoniacal solution? A. Yes, if done at once. 
Q. Why? A. The disease may make its appearance at any time. 
Q. Would you advise such treatment of a vineyard in which either 
rot has made its appearance? A. Yes. 
Q. Why? A. To arrest the disease, and to save the foliage, with- 
out which the vineyard can not either ripen its fruit, or its wood for 
another year’s crop, and also to prevent the appearance of the dis- 
ease for the succeeding year. 
Q. Would you spray with the ammoniacal solution a vineyard fully 
loaded with fruit? A. Yes; as under a change in atmospheric condi- 
tions the disease may occur at any time on any vineyard. 
Q. Then you would not fear an injury to the fruit in appearance or 
otherwise from spraying with ammoniacal solution? A. Not in the 
least. 
It might be interesting to note that one of the men employed by 
Mr. Moore applied some Bordeux mixture left from spraying the lat- 
ter’s vineyard to eight rows in his own vineyard of about three acres 
before blooming. The result is that, comparing the untreated vines 
in the remainder of his three acres with the eight rows treated only 
once, the untreated vines would have been benefited to the extent of 
at least one hundred dollars in value if the present crop had been so 
treated. sith 
Mr. Moore states that where a clinging bunch affected by the black 
rot had been left on the vines over winter (all affected berries of the 
last crop having been carefully plowed under) the neighboring vines 
were completely peppered this year with black rot. 
So far as the writer is able to make a comparison, there is no 
black rot at either Phelps or Orleans, but would advise Mr. 
Churchill’s early visit to both localities to examine and compare 
specimens taken from Lake Keuka. 
Some vineyards at Lake Keuka are affected by the diseases in some 
cases to the extent of fifty per cent of the crop, while others are free. 
Spraying has been done in other vineyards than Messrs. Fairchild’s 
and Moore’s, in all cases with beneficial results.
