On the Management of Grapes in Vineries, 99 



house anew, I should give more height to the upright sashes, 

 perhaps a foot additional, which would elevate the lower end 

 of the rafters, (and consequently shorten them a little), and 

 give them less inclination. The house is one hundred and 

 twenty feet long, being divided into two parts, each sixty 

 feet long, and both these have in their length fourteen raf- 

 ters, exclusive of those at their two ends. Each division has 

 a separate flue. The flues are carried from the fire places, 

 which are at the back of the house, along the middle, six 

 feet from the back wall, and are returned along the front, 

 passing afterwards into the chimnies at the back of the house, 

 close to the fire-places. The sides of the flues are elevated 

 above the surface of the mould ; the bottom of that part of 

 them which is in the middle, is a few inches below the level 

 of the wall-plate, but the upper part of their front line is 

 even with the wall-plate; consequently the front line is 

 lower than the mi die line : in front they are detached from 

 the wall, a cavity of six inches intervening. I attach, how- 

 ever, no particular importance to this arrangement of the 

 flues, (other plans may be equally as good), except that I 

 consider the sparation of them from the front wall to be es- 

 sential. The walk, which is two feet and a half wide, passes 

 at the back of the flue, in the middle of the house, and be- 

 tween it and the wall is a border raised to the level of the 

 wall-plate, three feet and a half wide, on which are grown 

 winter sallads and spring vegetables. No use is made of the 

 back wall : Grapes would not succeed on it, and other fruit 

 trees would interfere too much with the Vines which are the 

 ^rcat object of cultivation. The border between the two lines 

 of the flue is lower than the back borderland slopes to the
