Raising Varieties from Seed, 



It requires the burning sun of Italy to make 

 these roses produce their seed ; yet, by persever- 

 ance and careful cultivation, this desirable end 

 may be obtained. To raise a double variety of 

 Eosa Hardii is, at any rate, worth attempting. A 

 flued wall must be used to train the plants to ; and 

 in small gardens, where there is not such a con-

 or five feet in height and ten or twelve feet long, 

 of two courses of four-inch brickwork, with a space

 this pipe would heat the air between the two 

 courses of brickwork sufficiently for the purpose. 

 A fire should be kept every night from the middle 

 of May to the middle of July ; and this treatment 

 would possibly induce some of these roses to give
