ROSE GROWING IN WINTER. 167 



Silene class, and the consequence was in every case, almost 

 complete failure. This type evidently partakes more of 

 the Hybrid Perpetual than of the Tea class, and as they 

 are hardy and deciduous, refuse to blossom in midwinter, 

 unless given the rest that their nature demands. So far, 

 however, the new Roses, William Francis Bennett and 

 American Beauty, seem to prove an exception to this 

 rale, as they do well under the same treatment as the old 

 Teas. The past season we have found American Beauty 

 to do excellently well, if dried off like the regular Hybrid, 

 showing it to do well under both conditions. 



HYBRID PERPETUAL ROSES IN SOLID BEDS. 



Immense quantities of Roses of this class are now 

 grown in solid beds. These beds require no special prep- 

 aration where the soil is naturally good, and the natural 

 drainage perfect, but where this is not the case, the same 

 compost recommended for Tea Roses will answer, only 

 using a greater depth, from nine to twelve inches, over a 

 well-drained bottom. Hybrid Perpetual Roses, planted 

 out in solid beds, cannot be had so early as when grown 

 in pots, as, when thus grown, they cannot well be given 

 the rest necessary for early forcing ; as a rule, in this 

 district, they are rarely in market before February, and 

 from then they are brought in. in succession crops, until 

 the Roses from out doors in June come in. The distance 

 at which they are planted is usually from fifteen to 

 eighteen inches each way. 



MILDEW. 



Roses, when grown under glass, with proper attention 

 to temperature and moisture, are not usually attacked, by 

 Mildew ; but as a preventive it is well to paint the hot- 

 water pipes once every two or three weeks with a mixture 

 of sulphur and lime or sulphur and guano, made of the 

 consistency of whitewash (the guano or lime is merely to
