those required for exhibition only, may also re- 

 main there till near the blooming season ; Avhen, 

 if it is wished to retard them, they may be placed 

 under a north wall ; if to accelerate, they may be 

 removed to the greenhouse or to any pit or frame 

 under glass. 



With the exception of the Moss and Provence 

 Roses, which are, and always will be, favourites 

 for forcing. Summer Eoses are not so eligible for 

 pot-culture as the Autumnal Roses ; they bloom 

 but once, and, if intended for exhibition, it is so 

 extremely difficult to have them in perfection on 

 any given day ; if the season be cold and cloudy it 

 is most difficult to bring them forward, as fireheat 

 in summer is injurious to roses brought from the 

 open air ; and if dry and hot, it is equally difficult 

 to retard them ; at least, this can be done only 

 for a very short period. 



Moss and Provence Roses that have been forced 

 have generally been thought to require a season's 

 rest ; but with the following treatment this will not 

 be required. Presuming that they have bloomed 

 in February' or March, they should have their 

 shoots shortened to within two or three buds, 

 repotted and placed in a cold frame, plunged in 

 the before-mentioned materials, and, towards the 

 end of April, placed in the open air, as before 

 directed; if carefully . attended to during the 

 summer, the plants will be sufficiently vigorous 

 to bear forcing again the ensuing season ; those
