350 FORCING DEPARTMENT. 



CONSTRUCTION OF THE VINERY. 



The Vinery here forms a range of about 102 feet 

 in length, which is divided into three divisions, of 

 39 feet, 35 feet, and 28 feet each ; the smallest being 

 the central compartment, and intended for early- 

 forcing ; its being sheltered by the other two divi- 

 sions, less fuel is required to heat it in severe wea- 

 ther. The back wall of this range is about 10 feet 

 high from the floor level to the top of the rafter. 

 The front wall, which consists principally of piers 

 that are carried up from the foundation at three feet 

 six inches apart to the ground level where they are 

 connected together by a flag-stone, about two inches 

 thick, and extends from pier to pier, in order that 

 the roots may not be too deeply buried in the border, 

 which is frequently the case when these arches are 

 formed with brick-work. Above the ground-line, or 

 flag-stone, 15 inches of brick-work are carried up, 

 for the wall-plate or sill to rest on, that receives the 

 front lights, which, together with the wall, leaves the 

 front of the Vinery about three feet nine inches high 

 above the ground level of the border. 



There are, also, piers built in the interior, for the 

 support of the hot-water pipes, which are arranged 

 parallel to the front wall, about 20 inches distance; 

 a space reserved for planting the Vines in, which are 

 placed close to the wall, and their roots extend
