THE GRAPE DISTRICTS OF NEW YORK AND 
TABLE OF VARIETIES.* 
M. J. DORSEY 
INTRODUCTION. 
The basis of this bulletin is “‘ The Grapes of New York,” pre- 
pared by this Station and published by the State Department 
of Agriculture. In collecting the material for the grape book, 
much valuable information was contributed by the grape- 
growers of New York in co-operation with the Station. The 
edition of the larger work was necessarily limited. It is the 
purpose of this bulletin to place before the grape-growers an 
accurate summary of the information contained in the grape 
book. 
The bulletin contains: First, a discussion of the natural fac- 
tors influencing grape culture. Second, an account of the loca- 
tion, soil, climate, history and present status of the four great 
grape districts of New York. Third, a brief description of the 
most important species of Vitis, giving their natural habitat, 
botanical differences and horticultural importance, with the 
object of showing their significance in varieties. Fourth, a 
table of 161 of the most impcrtant varieties, giving the species, 
fruit and vine characters, date and place of origin or introduc- 
tion, and a brief statement of their value for the grower.

fined to four well-defined and specialized districts. This is
