have been known to flower when five or six weeks old. It is 

 best to prevent rather than to encourage flowering at such an 

 early stage, so that a good plant may be built up. As soon 

 as they flower all inferior blooms may be destroyed; preserve 

 the best ones and, to save valuable time, eyes may be budded or 

 cions grafted on to a vigorous growing stock. (See chapter on 

 The Seedling-Inarch and Nurse-Plant Methods of Plant 

 Propagation.) 



The Manetti is commonly used in America for this purpose. 

 The Brier is preferred for certain kinds and other wild or hardy 

 stocks may be tried. The Banksia stock has been proven very 

 good for yellow varieties. 



It will take several years to test a variety and to try it out 

 properly and decide whether it is worth growing and putting 

 on the market. There are many qualifications a Rose must 

 have and nothing hurts a firm's reputation more than to send 

 out a variety that will not prove desirable or profitable to grow. 



It is suggested that experiments be made in crossing the 

 hardy varieties or, at least, infusing some hardy blood into the 

 crosses so as to raise kinds which will be able to withstand 

 the severity of our American climate. The Rugosa, Wichur- 

 aiana and others of this type, are good to use for this purpose. 

 It would seem that to make the Rose more popular with the 

 masses varieties that succeed outdoors would be in great demand.
