CONSTRUCTION OF HOT-HODSES. §7/ 



stiucted ; and we fiiul plants tliriving, and plants 

 not thriving, in all kinds of stoves, pits, kc. The 

 culture of pine-a})ples is attended with a lieavier 

 expense than that of any other fruit under glass ; 

 especially if they be grovrii in lofty stoves, the erec- 

 tion of which is \'ery expensive, and the keeping 

 up proportionally more so, than that of humbler 

 stoves, or fined pits. 



But, independently of all considerations of ex- 

 pense (which may not be valued by some, provided 

 they can obtain good fruit), pine-apples may cer- 

 tainly be produced in as great perfection, if not 

 greater, and with infinitely less trouble and risk, in 

 ilued pits, if properly constructed, than in any 

 other way. I would therefore have the pinery de- 

 tached from the other forcing-houses, and to con- 

 sist of three pits in a range ; one for crowns and 

 suckers, one for succession, and one for fruiting 

 plants. The fruiting pit to be placed in the centre, 

 and the other two, right and left ; forming a range 

 of a hundred feet in length ; which would give 

 pine-apples enough for a large family. 



The fruiting pit to be forty feet long, and ten 

 feet wide, over walls ; and each of the others to be 

 thirty feet long, and nine feet wide, also over walls. 

 The breast- v/all of the whole to be on a line, and to 

 be eighteen inches above ground. The back-wall 

 of the centre one to be five feet, and of tlie others, 

 to be four and a half feet higher than the front. 

 The front and end flues to be separated from the 

 bark-bed by a three-inch cavity, and the back flues 

 to be raised above its level.
