qualities, appears to be the most practical remedy for the spraying 
of apple trees. 
DEPARTMENT OF HORTICULTURE. 
Apple districts of New York with varieties for each.—Bulletin 
275 defines the several distinct horticultural belts in the State, and 
names the varieties of apples that can be most successfully grown 
in each. It is also a catalogue of the apples that are grown or 
have originated in New York. The sorts listed are briefly described, 
the descriptions having been abbreviated from ‘The Apples of New 
York.” The bulletin was prepared to serve as a guide to those 
who are planting apples with a view of preventing the enormous 
waste occasioned by the continued attempts upon the part of apple 
growers to grow varieties that are not adapted to the regions in 
which they are planted. It answers as best this Station can the 
question so often asked: ‘‘ What varieties shall I plant?” 
The bulletin also considers, in leading up to the main questions 
as outlined above, the distribution of varieties of apples in which 
the fact is emphasized that domesticated plants, as well as wild 
plants, are distributed according to their vital necessities; and that 
success with any crop depends largely upon its being grown in an 
environment preeminently well suited to it; thus, distinct classes of 
farming land, or distinct sets of conditions, are being devoted, 
more and more, to special crops, a fact well illustrated by varieties 
of apples in this State. 
Another secondary but important fact set forth in the bulletin 
is that there are groups of apples, the members of which have about 
the same degree of suitability for a region. The formation and 
adaptations of these groups of apples are considered somewhat in 
detail with emphasis on the fact that groups of varieties have 
adaptations to particular conditions. The groups are founded upon 
the characters of the fruits and all characters are considered. The 
number of groups presented is thirty-six, containing 278 varieties. 
The factors governing the distribution of groups and varieties 
of apples is essential to a clear understanding of the matters dis- 
cussed in the bulletin. These are given as latitude and altitude, 
temperature, water, soil and air currents; each of these factors is 
briefly considered.
