CULTURE OF THE VINE, &C. 135 



are very improper for producing grapes at an early 

 season. 



Another kind of Grape-house is constructed on 

 a plan similar to that of a single-pitted Pine-stove. 

 In this, the flued wall should be about fifteen feet 

 high; the roof should be slanting, and should 

 cover an extent of about sixteen feet ; and a flue 

 should also run from the eastern to the western 

 extremity, near the front wall of the house. 

 These buildings are not only well calculated for 

 grapes, but also for early crops of melons, straw- 

 berries, &c. 



As glass is the principal article of expense in 

 erecting proper buildings for forcing, glass-frames 

 should be adapted, as much as possible, to answer 

 different ends and purposes. 



Where there are peach-houses, the glass-frames 

 may be made useful in a double capacity, by having 

 a building for Vines constructed of the same 

 dimensions as those of the peach-house. For as 

 peaches do not require to be covered with glass 

 later than the middle of summer, a crop of grapes 

 may be got by means of the same glasses after that 

 season. 



Melon-frames may also be applied to a double 

 purpose ; good crops of grapes may be obtained 

 from Vines trained against dwarf walls, that is, 

 walls about six feet high. Here a small slanting 

 roof should be made of proper dimensions for the 

 melon-frame glasses. In both the last-mentioned 

 cases, a small degree of fire-heat would be of sin-
