^6 THE FORCING GARDENER. [B. fa 



border, the choice of the kinds, and the 

 general management. I have formerly 

 had the conftrudion of three feveral and 

 differently-conftruded Grape-houfes in the 

 fame garden *, under my care, for years, 

 which then uniformly produced excellent 

 crops. This, in my opinion, is a proof of 

 the neceffity of a greater nicenefs in the 

 formation of the border being obferved, 

 than in the conftrudion of the houfe ; the 

 fire-place and flues excepted* 



A perfed command of fire heat is abfo- 

 lutely neceflary in the Grape-houfe ; to 

 effed which, proper attention fhould be 

 paid to the conftrudion of the fire-place 

 and flues. 



Fig. I. Plate V. reprefents a furnace, 

 and the entrance to the flue, on a plan 

 that has given the higheft fatisfadion for 

 many years : and although I fhould be 

 forry to advife unneceflary alterations in 

 houfes already built, yet I could wifh to 

 fee all hot-houfe furnaces conftruded on 

 the fame plan ; from a convidion of the 

 utility, not only in faving fuel, but in ena- 

 bling the operator to work with a degree
