formation of roots may be expedited by removing some 

 of the bark of the layer below ground on the side of the 

 parent tree. 



Where large numbers of layers are required, the most 

 suitable plan is to produce stools which send out 

 numerous shoots. Each of these shoots is then bent

back and fastened into the ground, where it remains 

 until rooted (Fig. 67). In England both the Lime and 

 Elm are propagated in this manner. 



3. Suckers. 



The root from which the sucker has sprung is cut 

 through, clean and slanting, on both sides of the base 

 of the sucker, the latter lifted out of the ground and 

 put out into the forest. The method is rarely used, as 

 disease is likely to be introduced through the cut ends 

 of the root. 



In some cases pieces of roots are planted out, which 

 produce roots and shoots. 



Note. Grafting and Budding, being outside practical 

 Sylviculture, will not be dealt with in this volume.
