ORCHARD HOUSES VENTILATING BY DRAIN PIPES.

a simple plan of admitting air through underground drain pipes, one end of these 

 air ducts passing outside and the other rising about the centre of the house or where 

 required, and covered with a movable lid for regulating the ingress of the air. This 

 system of ventilating by cold air drains has long boon practised in forcing operations, 

 and it is an excellent method for effecting a change of air in cold weather, when the 

 side ventilators of orchard houses or top-lights of other structures cannot be safely 

 opened. 



Some orchard houses are as elaborate in design as peacheries and vineries, and are 

 sources of great interest to the owners of 

 them and their friends. Such houses, 

 however, are no better for the production 

 of fruit than the simple and inexpensive 

 structures before figured and described. 

 All may be made as tenant's fixtures, if 

 required, by arrangement with the horti- 

 cultural builder, and can be taken to 

 pieces in a few hours. A useful house is 

 shown in the section (Fig. 62). It can be

CULTURE IN ORCHARD HOUSES. 



There are two modes : 1, planted-out trees ; 2, potted trees. By planted-out trees 

 is not meant those trained to trellises, but trees in bush, pyramid, or standard form, 

 similar to plantation and orchard trees, the latter giving the name to this system through 

 the first trees being grown as low standards in pots and allowed to form round heads. 

 Trees in the centre of a house 12 feet from the surface to the ridge should have the 

 branches start from the stem 4 feet 6 inches from the ground ; this will give about 

 6 feet for the head, which should always be kept 12 to 18 inches below the glass. Half-
