acteristics occurring in even our limited collection of these species, afford 

 more or less occasion. 



The indications of the correctness to name of variety, drawn from the 

 foliage and bloom, in advance of fruiting, are necessarily very uncertain. 

 For this reason the tabulation of varieties is deferred, till they can be 

 given with notices of the fruit.

To the one hundred and thirty-four varieties of grape jDreviously 

 planted, twelve were added last spring, making one hundred and forty-six 

 varieties in the collection. 



Down to near the last of March, the season was favorable. The purpose 

 had been to give the entire plantation a thorough spraying before growth 

 commenced. The material for the purpose was received at so late a date, 

 that only a portion of the grapes had been treated, when the process was 

 stopped by the occurrence of rain, which continued till the season of 

 bloom, and deferred the work still further, leaving the plants exposed to 

 the attacks of fungi, rendered still more effective by continuous wet. 



As soon as the grapes were out of bloom, they received a thorough spray 

 of Bordeaux mixture, which was repeated a couple of weeks later, with 

 the apparent result of checking the disease — a result which may have 

 been rather due to the recurrence of dry weather. 



The mildew {poronospora) has been chiefly noticeable upon varieties 

 partially or wholly of vinifera origin; such as the Kogers hybrids, Brighton, 

 and Empire State. A notable exception, however, occurs in the case of 

 the Downing, the foliage of which shows strongly marked indications of 

 European parentage; notwithstanding which it has, both this year and 

 last, been entirely exempt from the disease. 



Several varieties, also, have been seriously affected by anthracnose; 

 among which Vergennes, and several of the Rogers grapes may be 

 mentioned. 



A few rose chafers were discovered attacking the clusters when in 

 bloom. "With this exception, both plants and fruit have been mainly 

 exempt from the depredations of insects. 



In the following tabulation, these abbreviations only are used — E, 

 -^stivalis; H, Hybrid; L, Labrusca; R, Riparia; X, cross. 



The column headed " Productiveness," applies only to the crop of the 

 present year. Fungous diseases are specified under the head of " Remarks."
