HOW TO MAKE HOME 
several simple methods of root grafting; three, whip 
grafting, tongue grafting, and saddle grafting, will be ex¬ 
plained. In each case it is necessary to get the growing 
tissues (cambium layers) to coincide. If they do not, they 
will fail to unite. This growing tissue, or cambium layer 
is just inside the inner bark. Before grafting, the tops of 
the seedlings should be removed as the roots only are to 
be used. Thoroughly wash the roots (this is very essen¬ 
tial in order to keep the knife sharp). Cut them into 
pieces five or six inches long. Kach piece more than one- 
eighth inch thick will make a root graft. When the upper 
or distal end of the scion has been cut, the cut surface 
should be covered by grafting wax. 
WHIP GRAFTING 
For plain whip grafting, make long slanting cuts on 
the upper end of the root and the lower end of the scion so
