THE ART OP 



in grafting a rare Mexican shrub — Convolvulus macranthus 

 (Ipomcea niurucoides), of which there was only a single spe- 

 cimen in the establishment. The branches not severed from 

 the plant were grafted by approach on portions of the root 

 during the flow of the sap ; the portion of the root which was 

 grafted was not quite severed from the parent-plant, and was 

 planted in a small pot filled with soil. In a month the union 

 of the parts was completed. A few weeks afterwards the 

 portion of root was detached from the parent-plant, and sub- 

 sequently the branch grafted upon it was also gradually 

 severed. These grafts have prospered and reproduced several 

 specimens of the original plant. 



Hoot-Grafting hy Veneering. 



A portion of root is prepared by making an incision with 

 a notch at the top. The scion is similarly prepared by 

 making a corresponding tongue at the upper part of the 

 sloping cut. They are then placed together, so that the 

 tongue of the scion will fit into the notch in the root, and 

 bandaged without using mastic. The branching extremities 

 of the root are cut away, and the graft is planted in a half- 

 shady place in a sloping position in the trench, and covered 

 with good soil up to the upper bud of the scion. 



Root -Grafting hy the English Method. 



In this case the diameter of the scion is larger than that of 

 the root. The base of the scion is cleft, and the upper part 

 of the root cut in a sloping direction on both sides. The 

 cleft part of the scion is then placed on the top of the root, as 

 in saddle-grafting. The graft is bandaged with wool, and 

 planted in a shady place in a light compost. Should the root 

 be a long one, it is better to lay it in an inclined direction 

 in the soil rather than to plant it upright, as growth is sooner 

 promoted in the former position.
