 is paid to this in practice. If too much leafage, a part is 

 cut away. They are stuck deep enough, in the bench sand 

 to hold them erect. 



Cuttings are also rooted of such shrubs as weigelia, roses, 

 hardy hydrangea, and lilacs. "With such plants the cut- 

 ting is made with a bud at the base and a large part of 

 the leafage is cut away. It is found best also to use the 

 small side shoots that can be cut off so as to leave a little 

 ring of half-ripened wood at the base. In preparing these 

 slips a very sharp knife should be used and they should be
