work was also done il. the Prescott

which includes 1,216,960 acres.
To assist those who wish advice as
to rerlanting, the bureau has prepared
"a plans after examining 1918
acres. The area to be planted under
hese provisions is GAIA dcres. One
Begun is in Massachusetts. 1t is con-
trolled by the Metropolitan Water and
Sewerage Commission, and includes
l,500 acres In every case study is
made of the locality, the objects in
view and the best trees for the service.
Where it is desirable to fix shifting
beach sands, as along the Virginia and
Carolina coast and up in Oregon and
Washington, board fences are first
erected and grass is planted The
ground then becomes stable enough

ing been found that the sand hills OF
Nebraska are also adapted to forest
culture, two big reserves have been
established there and the work of
planting these will begin this next
spring.
Studies of the traits of various spe-
cies of trees have been in progress for
several years. A report on the Pacific
Coast redwood is ready for publication,
and one of the Bristle Cone fir of Call
ifornia is also completed. Attention
has been given to the distribution of
the red and black gum and cypress OF
the swamps, and to the yield and
growth OF the pines and oaks of Mich
lgan, the white oak and chestnut oak
of Tennessee, Kentucky and Missouri.
the lodgepole pine in Wyoming and
Montana, and the yellow pine in Ari-
iona.
Cooperative investigations are car
ried on in connection with state au-
thorities or with the United States Geo
logical Survey in several instances.
Thus the study of the Sierra Forest
Reserve of California; has now been
completed The report shows the dis
tribution of the different kinds of trees.
their value to industry and the effect
of fires on reproduction In this work
three million acres We're examined.
Several other researches of practical
Importance have been initiated. VAR
ieties of timber which may be service
able for paper pulp have been thor
oughly tested. A cheap method of ex
tracing resin from fir, so that the lat
ter may be reduced to pulp, easily, is
sought. An improved method of tap
ping the long leaf pine for turpentine
has been devised, thus insuring the
preservation of the trees from which
such supplies are obtained. Tests are
being made TO determine the strength
of various kinds of wood, and expert
ments are in progress with leather tan
ned by different banks, and special
study has been made of the cedar shin
gle industry of the Pacific coast.
