70 PRACTICAL ARBORICULTURE 



trees of the same species, from fourteen to twenty inches in diameter, which 

 were planted by persons who are still alive, within the past sixty years. These 

 latter have had room for root extension, while those of dense forests have been 

 overcrowded from the first germination of the seed. 



Since the poplar family is so well suited for paper, and grow more rapidly 

 than most other trees, some of these varieties should be planted extensively 

 for this special purpose. 



The Abele, which grows abundantly from suckers, is desirable for 

 planting in forest. The Carolina Poplar is easily grown from cuttings, and 

 is an upright and rapid growing tree. This tree is specially desirable for pulp 

 wood. 



It is not necessary to entirely clear away a forest in order to plant these 

 trees. Narrow lanes cut through the small inferior growths which have come 

 in since removal of the pine will suffice. The rapidly growing poplar will 

 over-top the dwarf growths, and overcome them. Yet in the long run it may 

 be better to cut the poor stuff off clean. 



The trees which will grow the fastest, provided they are suited for the 

 purpose, are the most economical to plant. 



Experiments with the Catalpa speciosa, as a tree for paper pulp, are being 

 made in Maine and other New England states. These experiments will be 

 watched closely by those interested in the subject. 



As is known the Catalpa possesses a long fiber, is extremely rapid in 

 growth, and perfectly at home in New England, as far north as 44 deg. lat. 



In this connection it has been said : 



"The question of the removal of the duty from wood pulp used in the man- 

 ufacture of paper is, as Mr. Hamlin, of The St. Paul Pioneer Press told the 

 Publishers' Association the other day, of vital importance to newspaper 

 makers. It is also a matter of some importance to Americans in general. 



"The best authorities calculate that there is enough timber now standing 

 in American forests to meet our present requirements for fifty years, but if the 

 annual rate of consumption of lumber increases as it now increases from year 

 to year, there is not enough standing timber to last us for thirty years ; and 

 the coniferous supply, that is the pines, hemlocks and spruces, will be all 

 cleared off in less than forty years, even if the present requirements are not 

 exceeded. 



"Forestry experts and censu? compilers agree with regard to this. Why 

 the activity of the lumberman's ax should be confined fo American forests 

 by a tariff which keeps out Canadian wood pulp from American paper mills 

 is indeed a difficult question to answer."
