fhut clofe on nights, and give but little air in unfavour- 

 able days. Rank fleam is fometimes drawn into a frame 

 from the outfide of the bed, occauoned by the mats 

 hanging over it ; therefore, in covering, it is neceffary 

 to keep up the ends of the mats, fo that the glafs and 

 frame only be covered. Danger of fleaming arifes alfo 

 from the application of frefh linings, the fmoke of which, 

 wind may drive into the frames ; fo that the lining 

 fhould either be covered with two or three inches of 

 mould, or, which is better, a good thicknefs of fine dry 

 hay. Sometimes fleam will iyhiuafe itfelf round the 

 frame within, through the bed fettling unequal! v. fo 

 that the mould draws from k : Prevent this by filling 

 up the apertures. 



Covering up at night has been juft directed to be

 welfare of plants, and guaM again ft permitting cover 

 longer than compelled to it* While the bed is in a 

 good heat, one mat is fufficient, but yet if the weather 

 is fharp, more fhould be ufed ; for though not neceffary 

 for the warmth, it will be ufeful to keep the fteam of 

 the bed from being fo fuddenlv condenfed as to drop on.

 clines in heat, and the weather is cold, a thicker cover- 

 ing muff be put on; and a very warm covering is made 

 thus : — lay on a mat, and over it a coat of flraw, or 

 rather hay, and then a mat on the top, which tack down 

 round the frame. It will help to warmth, to pufh into,- 

 the dung fome little flicks round the frame, and fill up 

 the fpace with hay. Covering vcund (he bed with flraw 

 and lining have been fpoken to : let the applications be 

 made in time.
