THE AUTUMNAL ROSE GARDEN. ]89 



from their roots, into a compost of light loam and 

 rotten dung, equal quantities (this is, on the 

 whole, the very best compost for potted roses), 

 watered, and again plunged till required for 

 forcing : this shifting would be better performed 

 in June, but, as the weather is then often hot and 

 dry, roses worked on the Dog Rose are apt to 

 suffer. Pots of the sizes called near London 24's 

 and 16's* are the best sizes for strong plants of 

 roses for forcing : when potted, the large and un- 

 yielding roots should be cut off close, so that 

 the plants may stand in the centre of the pots, 

 the fibrous and small roots merely tipped. 



The treatment recommended for roses in a pit 

 with Arnott's stove may be pursued with roses in a 

 house with smoke-flues or hot-water pipes. Ar- 

 nott's stove is recommended as an economical and 

 eligible mode of heating, practised here to some 

 extent with success for several years: on these 

 stoves an iron pan, fitted to the top, should always 

 be kept full of water. Koses may be forced 

 slowly, but with perhaps greater certainty, by the 

 uninitiated, by giving air freely and constantly in 

 mild weather during the day, keeping the fire 

 constantly burning during the same period as 

 recommended when keeping them closely shut up. 



* The respective sizes of these pots are, 24's, 7j inches deep, 

 and 8 inches over, measuring across the top of the pot ; 1 6's, 

 8^ inches deep, 9 inches in diameter.
