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

 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
