 niums, &c. and indeed heaths are of that unso- 

 ciable nature, that they will not do well if 

 mixed promiscuously with other plants, espe- 

 cially any of the broad leaved kinds : it is 

 implied by this observation, that there should, 

 if possible, in all large collections at least, be 

 separate houses for these very numerous 

 genera ; but in all houses there is a variety of 

 situations: some more airy, near the windows, 

 on end and front benches, for such as heaths, 

 Proteas, &c. ; all mountainous, Cape plants, 

 should be kept if possible on shelves, such as 

 graphaliums, bulbous geraniums, &c. &c. ; some 

 closer, as the principal stage and back benches, 

 for orange trees, geraniums, and all such as 

 grow in low sheltered situations : thus in every 

 instance, it is necessary to attend to natural 

 laabit. 



When they are all housed, and dirt of every 

 description taken away, let as much free air be 

 given as possible in the day time ; and even at 

 night, should the weather prove moderately 

 mild, and free from any appearance of frost. 

 In fact, I have seldom seen frosts at this early 

 season so severe, as to injure any green-house
