FERTILIZATION. 
Plant every fourth or fifth row of a staminate 
or perfect variety with the pistillate or imperfect 
to insure fertilization. 
WINTER PROTECTION. 
In this climate a covering of one or two in- 
ches is necessary, not so much to keep them warm 
as to prevent alternate thawing and freezing of the 
ground. Barnyard or stable manure and straw free 
from loose grain and foul seeds are generally used 
for this purpose. Marsh hay, leaves and cornstalks 
may be substituted. The covering should be done 
late in the fall after the ground is frozen, and re- 
moved in the spring, after vegetation begins to 
show greenness, sufficiently to insure the plants to 
grow through nicely. 
MULCH. 
A mulch (see Winter Protection) sufficient to 
insure clean berries should be used. Between the 
rows a mulch of five or six inches can do no 
harm; it will cause the ground to remain cool and 
moist, the berries to ripen a few days later; and in- 
crease the yield especially in a dry season. 
DESCRIPTIONS. 
A certain variety grows well in one locality 
and poorly in another; yields well on one kind of 
soil and poorly on another; produces well under
