any but the top ventilators, and these no more than is 
necessary to keep the thermometer from rising too high. 
Damp the floor, sides and ends of the house, so as to

from 60° at midnight, and 75° in cloudy, with a rise or 
85° to 90° on sunny days. Break off all superfluous 
growing shoots, thin the berries early, and reduce the 
crop down to what is finally intended, so that the vines 
may be eased as much as possible. The directions for 
January, in the Forcing House, will now apply to the
