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

 able days. Rank Jlcam is fometimes drawn into a frame 

 from the outfide of the bed, occafioned by the mats 

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

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

 frame only be covered. Danger of if earning arifes alio 

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

 wind may drive into the frames; fo that the lining 

 ihould either be covered with two or three inches of 

 mould, or, which is t etter, a good thicknefs of fine dry 

 hay. Sometimes iteam will infinuate itfelf round the 

 frame within, through the bed fettling unequally, fo 

 that the mould draws from it : Prevent this by filling 

 up the apertures. 



Covering up at night has been juft directed to be 

 only over the glades, for a reafon given.- Put the cover 

 on a little before fun fet, and take off a little after fun 

 rife, except very bad weather chelate otherwiie ; yet.,

 welfare of plants, and guard againll 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 mould be ufed; for though hot neceflary 

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

 the bed from being fo fuddenly e'ondenjid as to drop on, 

 the plants, which would injure them. As the bed de- 

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

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

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

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

 the dung fomc little flicks round t lie frame, and HI 1 up

 and lining have been fpoken to : let the applications be
