318 REPORT OF THE ACTING POMOLOGIST OF THE 
The following extracts from a letter of Mr. F. O. Fairchild, are _ 
presented ‘to show the results of his work the past season, and the 
benefits resulting from the sprayings in his own and neighboring 
vineyards: 
Hammonpsport, N. Y., December 5, 1890. 
G. W. Cuurcurti, Geneva, N. Y.: 
Dear Srr.— Yours of the third is at hand and contents noted. In 
reply I would say that I had little or no black or brown rots and 
their mildews, where sprayed. The same is true of Mr. T. Moore. — 
On the test rows left unsprayed the brown and black rot showed a 
loss of five to ten per cent. Our foliage continued healthy, and held 
on until maturity and frost, while on many not sprayed the leaves 
colored and dropped prematurely.’ The fruit did not color well or 
ripen. Mr. Charles Carey used it on Delawares, and where not used 
the fruit was very inferior. I do not call to mind over fifteen 
growers who used the spraying. The loss in many vineyards was 
from ten to twenty-five per cent. There has been much powdery 
mildew this year here, as well as elsewhere, especially in the Brocton 
district. Here it showed itself most on vines about 300 feet above the 
lake, mostly on Concords and Delawares, yet was seen on all varieties. 
There has been too many poor Delawares and Catawbas this season in 
this section, owing to these mildews, overloading, and poor culture. » — 
The immense crop in Chautauqua county of inferior fruit put upon 
the market in the latter part of the Concord season is, in my opinion, 
the cause of the extreme low prices, in connection with poor Catawbas. 
My fruit is very free from black and brown rot, well colored and 
ripened. [intend to be prepared to spray my entire vineyards next 
season before they blossom, immediately after, and again about July 
fifteenth, if the season seems to require it. 
Yours. 
F. O. FAIRCHILD.

Physalospera Bidwell. (Saccardo). 
The black rot rarely attacks the berries of the grape before they 
are two-thirds grown; the disease more often manifests itself on 
berries of nearly full size. It is rare also that all the berries in a 
bunch are affected, at least at the first infection; there are nearly 
always some few in each cluster that escape the disease. 
In its first manifestations there usually appears upon one side 
of the berry a livid brown spot, which gradually increases in size
