Forests

MISSOULA, July 1.-Acting in ac-
cordance with a request from the sec
retary of the Missoula chamber or COM
merce, the district office of the forest
service is collecting an exhibit for the
chamber of commerce rooms. The col
lection now ready comprises paper
pulps manufactured from the various
woods of this region, turpentine and
many other products distilled from
Douglas fir and samples of wood which
have been given a preservative treat
ment with creosote to make them resist
decay. These products will be installed
very soon.
To this exhibit will later be added
other specimens, making a complete
display of each of the species found in
Montana and of their. products. Sec
tions of the tree trunks, specimens OF
the twigs and flowers and samples of
the lumber manufactured from each
species will be shown.
Wood which has been subjected to
strength tests and photographs and
engagements will illustrate the impor-
tant phases of forestry work on the
national forests.
The collection of paper pulps COM
prises samples made from each of the
important woods of the northern Rock
les and shows the wood fiber in both
the unbleached and bleached state,
with a statement of the amount of
chemical required to bleach the fiber.
These specimens, which were prepared
in the forest service wood chemistry
laboratory in Washington, show that
from many of the Rocky mountain
species paper can be made of as good
quality and as cheap as that obtained
from the eastern spruce, while the
abundant water power in this region
offers uneXcelled advantages for its
manufacture.
DlstiIIation Products
Another valuable object lesson is the
collection of Douglas fir distillatlou
products presented to the forest serv
ice by a wood distilling company of
Oregon. These products include tur-
pentine. rosin, tar, pitch, wood creo-
sote, charcoal and various oils, as well
as fruit sprays, dsinfectants, shingle
stains and other useful materials
which are made from the oils.
All of these come from the pitchy
wood of the common red or Douglas
fir, which is plentiful throughout the
Rocky mountains and Is the great tim
ber tree Of the Pacific northwest.
These products suggest great possibil-
tiles for the utilization of waste wood,
as they can be obtained from pine as
we'll as from fir.
Il
timbers which were treated with pre-
servatiyes in Forest service treating
plants illustrate the thoroughness of
the methods which the service is now
using in it's demonstration work, while
teaching wood users the best way to
treat timber so as to double its life.
The district Office will supervise the
construction and experimental opera
tion of several wood preserving plants
70. 10 Ar-F1n ,t,,rr
summer in order that the use of treat
ed ties. poles, posts and mine timbers
may come into more common use and
their value be better understood.
Valuable Photographs
The species display win attempt to
give an accurate idea of each kind of
wood that erows he region. The
twigs and comes 10 ark and the poll
ished section Qf the tree trunk will
help people to comp ire and identify
trees they do not know, and the sam
