6l 0^ THE CULTURE 



The air arid heat in the frames are always moft 

 regular and fleady when the wind is calm, or the 

 bed well protected, and when the wind is in the 

 fouth or in the north ; but when the wind blows 

 ftrong from any of the other quarters, and is fufFered 

 to beat upon any part of the bed, the current of air 

 will be irregular, and at times very ftrong ; and if 

 there then happen to be a ftrong new lining at the 

 bed, and a great rank fteam arifing out of it, efpeci- 

 ally at the north fide, care, ikill, and attention will 

 be required, and muft be exerted, for the preferva- 

 tion of the plants ; for the fteam being nigh to the 

 place where the air is admitted, if much air be given 

 ■while the wind continues high, the fteam will un- 

 doubtedly be carried by the current of air into the 

 frames, and if the fteam be of a pernicious quality, 

 the plants will certainly be hurt thereby. When fuch 

 a cafe happens with me, I give but little or no air in 

 the night time, and by frequent waterings I keep 

 the fteam of the linings down in the day-time ; and 

 this I continue to do till the winds fubfide, or till 

 the violent fermentation of the linings be fomewhat 

 abated. But if the bed be well flieltered, fuch precau- 

 tions will be unneceilary, for I have never experien- 

 ced any hurtfulnefs in the fteam arifmg out of the 

 linings, except when the winds have been blowing 

 ftrongly on the bed, and foon after the application 

 of a powerful new lining of rank horle-dung, and 

 when it was high up againft the fides of the frames 

 near to the place where the air was given ; and even
