GRAFTING 57 
in the scion requires. Both parts are then fitted without 
a cleft or an incision being made in the wood, and, after 
being tied closely with a woollen or a cotton bandage, are 
placed in close frames, with or without grafting-wax. 
The stock should not be headed at first; when the parts 
have properly united it may be gradually removed. 
This method answers well for Rhododendrons. 
Grafting by Approach, or Inarching. 
The oldest system is thus known, and examples are 
frequently seen in trees growing naturally together. It 
was formerly practised with trees to form arches, door- 
ways, etc., for picturesque effect, but is now more 
generally in use for propagating plants that do not 
succeed well under other methods. 
The season for grafting by approach begins with the 
flow of sap in the spring and ends with it in autumn. 
The operation is performed when the leaves are on the 
plants forming the stock and scion, and they are allowed 
to remain on both for some time. The scion intended 
for inarching must either be a movable pot plant (as 
shown in the illustration) that may be taken into any 
place desired, or one planted in close proximity to the 
stock. A similar portion of wood should be removed’ 
from both the parts intended for joining, and they must 
be carefully fitted together and secured with tying 
material and a bandage. 
Sometimes a tongue is cut in the plant forming the 
scion and made to fit into a corresponding notch in the 
stock at the point where the barks meet. In other 
methods of inarching the stock is cut off and the scion 
inserted on or near its point, and for restoring defective 
parts the terminal point of the scion is cut with a
