7^ ON THE CULTURE 



When the bed Is firft built, the pits are about three 

 feet in depth below the furface of the flues. Thefe 

 pits I have filled up about a foot high, fome of them 

 with rough chalk, fome of them with fmall floncs, 

 and fome of them with brickbats * : I his is to let the 

 wet drain off freely hotn the mould of the beds. 

 After this filling up with chalk, ftones, and broken 

 bricks, there is a vacancy in the pitg about two feet 

 deep below the furface of the flues ; this vacancy I 

 have filled to a level with the furface of the flues 

 with vegetable or leaf mould ; and inputting it in, it 

 is gently preiled, to prevent it from fmking too 

 much afterguards. 



On the furface of the mould which the pits are 

 filled with, under the middle of each light, and 

 which is jufi in the centre of the mould in each pit, 

 I make hilU oi mould in the fame form as is com- 

 monly done on a dung bed. Thefe hills are to fet 

 the plants in, and are raifed at firfl nearly clofe to or 

 within a few inches of the glafs. Raifing the mould 

 at firli pretty nigh the glafs is neceifary on account 

 of the fmking of it ;. for as the frames are fet on 

 bricks they cannot fmk, but mould newly put in 

 is fure to fettle, and the meafure of fettlement will 

 ever depend upon the lightnefs and texture of the 

 mould with which the pit-, are filled. Therefore, 

 thefe and fuch-like matters mufl be left to the difcretion 

 of thofe who are entrufted with the direction and ma- 

 nagement of the frames. When the bed is thus 



* Either of thefe, or fuch like, will do eq.ually well.
