where it may be utilised in copse or as a 

 standard. 



19. Populus canadensis and balsamifera. 



These free, rapid-growing kinds of deciduous 

 trees will do in moderately good, but fresh soil. 

 It is cultivated by means of cuttings or raised 

 from seeds, in which case it is important to note 

 that the seed loses its germinating power a few 

 days after maturity. Even root shoots can be 

 used as planting material. Recommended to be 

 planted pure on river banks. 



20. Prunus serotina. 



Wherever the sweet chestnut or oaks grow 

 this cherry-tree also thrives. It is a rapid- 

 growing, deciduous tree which can be grown 

 on medium and good soils (from pine soils 

 third quality upwards). Cultivation in groups 

 amongst broad-leaved trees, and it is useful for 

 underplanting of light-loving species, filling up 

 of holes due to snow, &c., in young pine plan- 

 tations. 



21. Quercus alba. 



The white oak can apparently be raised 

 wherever the indigenous oak grows, with which 

 it also shares precisely the same method of 

 treatment.
