CHERRIES IN HOUSES.

house wide at 50. and close at 55, if it is desired to accelerate the ripening, other- 

 wise air can hardly be given too amply to cherries under glass. Later crops may have 

 the house left open day and night during the finishing of the fruit, for the chief con- 

 sideration as regards these is protection from rain and birds. Exclude the latter by 

 covering the ventilation spaces with small-meshed netting. 



When the fruit is gathered remove the roof-lights, and do not replace them until 

 the buds are advanced in swelling the following spring. Top-dress the borders with 

 fresh loam, cleanse the house, dress the trees, and keep an eye on birds, which some-

 ventilators ; also attend to the watering and syringing of the trees, so as to keep the 

 foliage healthy till it falls. 



Forcing. The chief point to be attended to in forcing cherries is the ventilation. 

 This needs to be free at the time the trees are swelling their buds and developing the 

 flowers, as well as during the blossoming, setting, and stoning of the fruit. Cherries are 

 debilitated by a close atmosphere, the trees shedding their blossoms without setting
