Tan. The Gardeners Kalendar. 31 

 therefore it is very ufefu! to have a flue con- 

 trived under the pavement, in the front of the 

 green-houfe, w^hich may be ufed in very hard 

 winters, v/hen it will be very dijSicult to keep 

 the frofl out of the houfe, where this is want- 

 ing ; but where there is no fuch contrivance, 

 the glalTes in front fhould be clofdy covered 

 with mats, reeds, or ilraw ; and you ihould 

 light fix or eight large candles to burn in the 

 green-houfe every night \ which are much bet- 

 ter than burning of charcoal, as is by fome 

 '-pradifed, which is equally pernicious to plants 

 as animals, where the air is confined, as in 

 green-houfes it muil be, when they are clofcly 

 {hut. Befides, in great thaws, when the air is 

 filled with moiflure, which occafions a great 

 damp in green-houfes, it v/ill be of great ufe 

 to make two or three gentle fires where there 

 are flues to rarefy and warm the air, which 

 otherwife often occafions the leaves of the trees 

 to grow mouldy, and drop off. 



You muft alfo obferve to pick off all dead 

 leaves, or fuch as are mouldy, which, if fuf- 

 fered to remain on, would infed: thofe which 

 grow near them, and alfo corrupt the air of 

 the houfe, to the prejudice of your plants ; 

 befides, this adds a neatnefs to the houfe, and 

 renders the plants more beautiful, as alfo more 



healthful.
