GREEN-HOUSE DISPLAYED. 5I5 



Daring the Winter feafon, continue to ad- 

 mit air lefs or more every mild calm day, by 

 opening feme of the windows, from nine or 

 ten, to three or four o'clock in the afternoon, 

 but if the weather changes lliarply cold at any 

 time of the day, (hut the windows, or in \^Ty 

 wet or foggy weather, generally keep the 

 Green-houfe clofe to exclude the damps as 

 much as poflible ; and in frolly weather, be 

 careful to defend the plants by keeping the 

 gldfles conftantly {hut, except when but mo- 

 derate froft and calm fun-fhining days occur, 

 may give air moderately two or three hours 

 in the middle of the day ; but otherwife keep 

 all clofe ; and in very rigorous frofts, it is 

 proper to defend the glafTes on the outfide 

 with ihutters, or in default of thefe, with 

 large thick garden ma^ nailed up clofe, and 

 which may continue both night and day ; or 

 in fun-fhining days, the mats may be part 

 removed in the forenoon, but applied again 

 foon in the afternoon, while the froft conti- 

 nues fevere ; likewife in (harp frofty weather, 

 if the Green-houfe is furnifhed with flues, 

 make moderate fires every evening, alfo in 

 the day time, when the froft is very fevere, 

 and alfo in very foggy, or in exceffive wet 

 weather, or ftrong thaws after long fevere 

 froft, &c. gentle fires in an evening or morn- 

 ing, occafionally, will be necefTary to expel 

 the damps. 



In mild weather, give fometimes gentle 

 waterings when the earth of the pots appears 

 dry, obferving, in this, to give it very 

 fparing and feldom to the fucculent exotics,
