appearance of the malady, intelligently apply the rocasies fot 
to be the most certain to protect him from loss. The Station | 
and these have remained quite exempt from the attacks o 
fungi. We have been in constant communication with growers, 
and numerous inquiries are received asking for advice as to the 
best methods of dealing with insects and fungi. We have there 
fore compiled some of the most interesting reports of visits to the _ 
larger vineyards in the immediate vicinity, and at Hammonds- — 
port, on Keuka lake, where some of the largest vineyards in the 
State are located. The reports will show the nature and preva- — 
lence of disease, with the estimated amount of injury to the crop, __ 
in both treated and untreated vineyards. They will also give - 
formulas and methods used in applying the fungucides on a large 
scale and by some of the most practical and energetic growers in 
the valley, they having had the advantages of personal instruction 
from such specialists as Colonel Pearson and Professor F. Lamson — 
Scribner, of our own country, and Professor Viala, sent ascom- 
missioner by the French government to make an investigation of 
diseases affecting the American grape during the month of J a im 
1889, when this section was visited so disastrously by black and — ay 
brown rot. We have also added descriptions of the most common 
of the fungi attacking the vine, foliage and fruit of the grape, 
compiled from the department circular and other reliable sources. — ich 
We make no apology for offering these reports and compilations, — a, 
as nearly all of the correspondence in this department relative to 
the grape during the past year has contained questions that are 
answered, as far as present knowledge of the subjects will warrant, 
in these reports.

Dr. Peter Couuier, 
New York State Experiment Station, Geneva, N. Y.: 
Dear Str.— In accordance with your suggestion, the writer visited 
Hammondsport, N. Y., and examined the vineyards in the immediate — 
vicinity, with a view of verifying the current reports as to the preva- 
lence of black rot.(Physalospora Bidwellit), as well as downy mildew 
(Peronospora viticola) and powdery mildew (Uncinula Spiralis), and, 
if possible, to ascertain whether any or either of these diseases of the » 
grape vine prevailed in the vineyards near Orleans and Phelps.
