DIMENSIONS OF THE VINERY 13 



under the same conditions, yield crops of grapes as good 

 and satisfactory in every way as will the more expensive 

 ornamentally constructed vinery. But where wall space 

 having an aspect facing due south or south-west 

 is available, there is no more suitable description of 

 vinery for the production of early grapes that is, 

 grapes to be ripe in May than that known as a 

 " lean-to." Of course, grapes to be ripe during the 

 months of June, July, August, September and October 

 may be and are successfully grown in " lean-to" houses. 



The next best shape of vinery for walled-in gardens 

 is that known as the "hip-roof," or "three-quarter 

 span. This form of vinery affords more light to the 

 interior through the back roof than would be obtained 

 in the case of a "lean-to" house. 



In both, front ventilation may be admitted through 

 continuous front glass lights worked by machinery, 

 or the front ventilation may be effected by a series 

 of boxes built in the front brickwork, and regulated 

 by either sliding or hanging shutters. The top venti- 

 lators should open the full length of roof by machinery. 

 Another house is that known as the span-roofed vinery. 

 This should run north and south, so as to admit of the 

 vines having the full benefit of the sun throughout the 

 day. The span is invariably used for the production of 

 fruit, both early and late in the season, where no wall- 

 space is at hand for the lean-to or three-quarter span. 

 The span-roofed vinery has much to commend it to those 

 interested in the production of all kinds of fruit and 

 plants, not only on the score of economy, but also on 

 account of the advantages which it affords from a 

 cultural and productive point of view.
