60 BULLETIN 1241, U. S. DEPARTMENT OF AGRICULTURE. 
Potential growth under intensive forestry of the four or five types containing 
soda-pulp timbers is very large, reaching nearly 29 § million cords a year. Out 
of this total could unquestionably be secured soda pulp wood enough to meet all of 
our present deficit of 196,000 cords, and in addition enough to meet for an indefinite 
period to come the annual increase in our needs which now amount to 23,000 
cords. Relatively small areas devoted exclusively to the growing of soda-pulp 
species would produce the entire amount of the present and greatly enlarged 
future requirements. 
NATIONAL TIMBER GROWTH UNDER FOREST MANAGEMENT. 
In some of the more critical types and regions, as for example the spruce-fir 
type in the Middle Atlantic States, the current pulp-wood demand alone would 
absorb all or more than the total estimated growth under intensive forest manage- 
ment. Intensive forestry on the entire area of the type would, therefore, be 
necessary to support an industry of the present size under present pulping pro- 
cesses. In other types and regions, however, the pulp and paper industry could 
meet its own requirements from relatively small areas of forest land intensively 
managed or from larger areas with a cruder system of forestry. The use of 
southern pines for sulphate pulp is a case in point. In either case pulp and paper 
concerns have the opportunity to secure and reforest land areas sufficient in size 
to meet their own supplies. 
Regardless of whether either of these two or an intermediate condition obtains, 
however, the question of pulp-wood production and that of wood production for 
all other purposes upon the entire area of forest land, are so closely related that 
they can not be separated. The consideration of possible timber growth, there- 
fore, affords a necessary background both from the standpoint of the public 
interest and that of the pulp and paper industry, for the solution of the whole 
pulp and paper problem. 
POSSIBLE GROWTH UNDER CRUDE FOREST MANAGEMENT. 
Forest lands in every timber region of the United Stales car, be kept productve 
by simple, practical-, and relatively inexpensive measures. On some lands 
thoroughgoing fire protection alone will assure a new crop, not necessarily of 
the best species in the least time, and almost certainly with reduced yields, but 
still timber crops. In other forest types such additional measures as the reserva- 
tion of seed trees or of the smaller trees at the time of cutting will be necessary. 
Such measures as these constitute a preliminary step toward intensive forest 
management. 
Under such simple measures, however, it is estimated that the present annual 
growth in the entire United States of 6 billion cubic feet could be increased by 
to 10 billion. Ten billion feet, however, falls far short of the 25 billion 
feet now taken from the t fn sts or destroyed, and at the present rate of use. (am- 
ber sc making itself felt in other products than pulp, including such iin- 
int products as lumber and ties, 
pie forestry measures, however, if continued for a long enough pe 
could be mane still more productive. The effect of cumulative lire protec- 
tion would be pronounced and the area containing growing stands oi timber 
would be steadily increased, so that ultimately it is estimated under these 
; 'i od our 170 million acres of forest land might be increased to 14 
billion cubic feet. Fourteen billion feet is better than ten, but the possibility of 
this annual growth is far in the future and is still only a little more than half of 
what we now destroy or Use from the forest each year. A limitation to any Mich 
i would inevitably mean a most drastic reduction in timber use in the
