GROUND-WOOD PULP. 67 
Similarly, jack pine, which is also unsatisfactory for news-print pur- 
poses, can be used very effectively in the manufacture of box boards. 
When combined with a large proportion of sulphite any of the woods 
tested, except the hardwoods, should produce a satisfactory manila 
of a color other than white. For the manufacture of wood-pulp 
boards, jack pine, tamarack, loblolly pine, and larch, in addition to 
the woods mentioned as suitable for news print, should furnish accept- 
able material. When high color is desired, and a somewhat poorer 
one in the center of the board is not objectionable, black gum or 
poplar could be used as a liner, 1f combined with a small percentage 
of sulphite. In the manufacture of box boards from steamed wood 
all of the conifers tested could be utilized, except where the product 
was to be astrong container board. The spruces, however, will yield 
a steamed pulp suitable for almost every kind of container. 
It will be noted that the great majority of the substitute woods are 
confined to the West, while the ground-wood industry at present 
obtains the bulk of its supply of raw material from the East. The 
industry, however, is really a frontier one. It must have a plentiful 
supply of wood and an abundance of cheap power, two things not 
readily obtainable in settled communities. As the regions in which 
the industry is now centered develop it will have to move on to other 
and less-settled ones. On the National Forests are immense quantities 
of many of the woods tested and abundant opportunities for power 
development.
