that, when the heat of the bed declines towards 

 the middle of July, the pots must be removed, 

 some fresh dung added, and the bed re-made, 

 again plunging the plants immediately. Towards 

 the end of August the roots of the plants must be 

 ripened ; the pots must, therefore, be gradually 

 lifted out of the saw-dust ; i. e. for five or six days 

 expose them about two inches below their rims ; 

 then, after the same lapse of time, a little lower, 

 till the whole of the pot is exposed to the sun and 

 air ; they may be then removed to the greenhouse 

 so as to be sheltered from heavy rain. They will 

 blftom well in the autumn, and be in fine order 

 for early forcing ; if plants are required during 

 the summer for exhibition, or any other purpose, 

 care must always be taken to harden or ripen 

 their roots as above before they are removed from 

 the hot-bed. 



A very excellent method of cultivating these 

 beautiful roses is to plant against a wall with a 

 warm aspect, some vigorous-growing climbing 

 roses, and when they are well established, bud- 

 ding their branches with the finer varieties; they 

 then bloom in the ^highest perfection. One of 

 the best to form a stock for this purpose is the 

 Banksian Eose, Eosa Fortuniana. The black 

 Boursault introduced by Mr. H. Curtis, and so 

 called from the dark colour of its shoots, is also 

 an excellent sort for this purpose.
