196 Principles of Plant Culture. 
The cut forming the distal end of the cutting is preferably 
made considerably above a node, in order that the bud 
may not lose an undue amount of moisture by evap- 
oration from the adjacent cut surface. 
Cuttings of certain plants that do not readily 
form roots when made in the ordinary way, may be 
induced to do so by “ringing” (428d) the branch 
from which the cutting is to be made, just below a 
node, at about midsummer. Callus will then form 
at the upper edge of the ring (80), and 
food will be stored in the stem immediately 
above it. In autumn the branch may be 
severed just below the ring, and a cutting 
made, of which the base shall include the 
callused part, and which may be treated in 
the usual manner.
