full a conclusion.
However, 1t was only recently that he
began his experiments with cornstalks.
His first steps were guided by the !heoty
that other woods could be employed with
as good or better results than the rapidly
disappearing species SO exclusively used
This idea caused the paper manufac-
turers of the country to smile pityingiy.
They had tried other woods and they
were sure that for the manufacture or
pulp at least, they were useless.
Nevertheless, samples Of every kind OF
wood were obtained by the government
factory, their fiber and chemical com
position carefully studied and then they
were put through the pulp making pro-
cess The results proved that While
each species demanded particular treat
ment. one was quite as good as another
and that a particularly fine quality Of
pulp and paper can be made from white
fir and scrub pine. of which there are
millions of acres of vast, uncut tracts
Up to the present time these species
have been going to waste for lack or
some commercial means of dlsposing or
them. They have been but little used
for lumber, and their proportion IN the
forests has therefore tended to IN
crease On the other hand, spruce. pop
lar and hemlock have yearly grown
more scarce, fact easily understood
when one considers that last year
alone the manufacture of pulp necessl-
tated the stripping Of an area nan as
large as the state of Rhode Island.
The Possibilities Discovered.
The substitution Of white Ar and scrub
nine for these woods Is in itself enough
to insure against the destruction OF tiie
forests for the time being. but SO cohlih-
ually does the demand for this proouce
increase that even the supply OF THESE
substitutes must eventually be exhausted.
With the cornstalks, however. no sucn
fear need be entertained. Billions VI
stalks are yearly used as fodder, out De

reau show that there are more IMAM

what this means to the farmer can be
