What il Comprises and How il /,
Arranged at the St. Louis
Fair.

Fair.
The Bureau of Forestry of the L. s.
Department of Agriculture has pre-.
pared Tor the Louisiana Purchase Ex-
position the most extensive display it
has ever made, The purpose is both
to Illustrate the work which the bu
reau is doing and to show actual for
est conditions IN all parts OF the coun-
try. The visitor will see there the
most impressive of what practical
forestry is, and also its great present
and future Importance as means of
promoting the national welfare.
laundering ranks fourth among the
industries of the country. and it is
matter of hopeful promise for The
permanence of the industry and for
the cause of forestry that lumbermen
are adopting conservative forest man
agement in their lumber operations.
That agriculture, incomparably the
most important of our national
sources of wealth, also depends in no
small degree on forestry, is not how
ever, so well understood. Under in.
tensive methods of farming, and with
the enlargement of the cultivable area
made possible by irrigation, this de-
pendence will become increasingly
close. Mining and grazing, too, ma.
terially depend or forestry, for mines
demand cheap and abundant timber,
aud the forage which feeds most of
the western stock is one of the impor-
tant indirect products which under
proper restrictions, the forest may be
made to yield, All of these relation
ships are strikingly displayed in the
Forestry exhibit at st Louis.
The space allotted to the Bureau of
Forestry is in two different though
not widely separated parts of the
Fair grounds. An indoor exhibit is
located in the Forestry, Fish and
Game Building, in which is centered
also an exhibition of the lumber in
dustry of the United States. A strik-
ing and complete collection of photo
graphic transparencies illustrate for
est conditions and problems as they
are encountered by the Bureau. Ty-
| nj al nd
ting or harvesting of forests and their
renewal by natural reproduction, for
est planting in treeless regions or
where forests have been destroyed,
and damage by fire, insects, over
grazing, etc, are shown most clearly
| Nearly all of the transparencies are of
large size, some of them by feet
They are arranged to be seen from
the inside of an arcade illuminated by
ern forest scenes shown on opposite
walls. This series is supplemented by
a collection of large colored bromide
! photogl aphs framed in the panels of
the balustrade which surrounds the
exhibit space. On the floor between
the balustrade and the arcade are
cases which display some specially
important phrases of the Bureau in
vestigations, together with collec.
ton OF all the instruments used in for
est work, the publications of the Blu
Teau, etc. OF particular interest is a
large case containing longleaf pine
trunks which show the advantages OF
the new system of turpentining pro
noted by the Bureau and the disad
| vantages and injurious effects of the
system of boxing. Two other cases
exhibit insects and examples of their
| destructive work. The method Of de-
termining the strength Of commercial
! timbers is shown by testing machine
and the results of tests are shown by
charts and tested timbers. There is
also large collection of timbers, both
! from the United States and Europe,
treated by different preservative pro
cesses to show the manner of increas-
/ ing the life of various construction
! timbers Several specimens are
shown of building and other timbers
which have been in use for thirty
years or more,
| One OF the special features of the
exhibit is a relief map OF the United
States cast upon a section OF a sphere
I 16 feet in diameter, BY using this
/ type of map the geographical distor-
I don inevitable In fat maps is avoid
/ ed, and the real relationship Of the
various parts of the country and
their actual position on the globe are
correctly shown. The distribution
and character of the forests OF the
country are shown in different colors,
as are the location and extent Of the
national and state forest reserves.
/ The forests managed according to
working plans prepared by the Bu
reau and lands upon which plantations
/ have been instituted under Bureau
/ planting plans are also indicated by
special symbols. The situation Cf
