76 SCIONS. 



It is certain that scions thrive better on some 

 stocks even of the same species than others, 

 and that this depends somewhat on the soil in 

 which the stock grows ; this is a subject how- 

 ever on which there has been so much discus- 

 sion, and on which practical experience has yet 

 so much to develop, that no certain general 

 rules can be laid down, particularly in this 

 country. 



From what has been said on perspiration it 

 seems that the practice of budding on the 

 northern side of stems must be correct. 



Mr. Knight often applied two ligatures to his 

 buddings on Peach trees, one above the bud 

 across the transverse incision, the other below, 

 this last was taken off as soon as the bud ad- 

 hered, the upper one was left on, thus obstruct- 

 ing the flow of the sap upwards and throwing 

 it into the bud, which then vegetated early and 

 produced blossoms the following spring. As 

 soon as the new shoot had attained about four 

 inches in length the upper bandage was re- 

 moved and the sap suffered to flow freely. By 

 following this practice with roses, and by judi- 

 cious heading down, I have obtained very large 

 and healthy bushes on the top of a single 

 straight stem the third year.
