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 wil! 
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 census compilers agree with regard to this. Why 
the activity of the lumberman’s ax should be confined to American forests 
by a tariff which keeps out Canadian wood pulp from American paper mills 
is indeed a difficult question to answer.”
