or of the greater part of all the principal branches (Fig. 

 72), after which the shoots which are given out are cut 

 back at intervals of one to two or even more years. 



In Europe the willow is subjected to this treatment 

 in order to provide withes for basket-making or hoops 

 for casks. In the Tropics several species might be 

 treated in the same way for the same purpose, or for 

 that of yielding leaves for fodder or for manure, or for 

 raising silkworms. In places where canes, bamboos, or 

 woody twiners are abundant, it is probable that this 

 method of treatment for basket-making will not be in 

 much request. 



(d) Regeneration from Culms. The regeneration of 

 bamboos comes under two heads, viz. by seed and by 

 culms from the rhizomes. When a bamboo clump seeds 

 it dies, and further production of culms must be effected 

 by the seed which it sheds. This seeding may take 

 place after a considerable number of years have passed, 

 and in the meanwhile the annual production of a certain 

 number of culms from the rhizomes has to be effected. 



Bamboos may be classed into two categories, viz. 

 those which give out long rhizomes and which produce 

 culms at appreciable distances from one another, thus 

 forming naturally open clumps, and those with short thick 

 root-stocks, giving out culms in somewhat dense masses 

 together, forming close or " tufted " clumps.
