274 THE FORCING GARDEN* 



cherries, or all of these, might be planted in the 

 border. The flues might also be occupied, as above 

 hinted, with strawberries, &c. 



3* Of the Grape-Home. 



A grape-house for early forcing, to be command* 

 ed by one furnace, should not much exceed thirty 

 feet in length. If it were forty or forty-five feet 

 long, it would require two furnaces to be placed, 

 and the flues to run, as described below. The 

 width of the house may be ten or eleven feet, 

 and the height thirteen or fourteen ; the front, in- 

 cluding parapet and glass, not exceeding four 

 feet in height. But, if the roof were made to rest 

 on the parapet, without having any upright glass, 

 and if the parapet were about eighteen inches high, 

 it would have a better pitch, and there would be a 

 longer run for the vines. 



The front flue should be two feet clear of the 

 parapet, should return in the middle of the border, 

 and double by the back wall, being separated from 

 it by a three-inch cavity, that is, in the case of there 

 beingbut one furnace for the house. But if the house 

 be much above thirty feet in length, and require 

 two furnaces, one should be placed at each end, in 

 the shed behind, and the power of both should be 

 brought to the front, the flue of the one to be 

 placed within two feet of the parapet, and of the 

 other close behind the first, being separated by a 

 two-inch cavity only, and both to stand on a com- 

 mon foundation. The one may return in the 



middle of the house, and the other by the back-
