Y SHAPED FLUMES
FOR TRANSPORTING
TIMBER LOGS
Bulletin Issued by the Department of
Agriculture Recommending This
Method of Transportation in
Mountainous Regions.

OF interest to this section is bulle-
tin just issued by the Department of
Agriculture describing the use of the
w shaped fiume for transporting tim
Der loges in mountainous region. This
is one method of transportation pro-
posed to be used by The White Noun
tain Lumber Company, of Clifton, in
the transportation of timber logs
from the Apache Forest Reserve in
this county to the saw mill in Clifton.
The White Mountain Lumber Co. has
applied for more than a million and
a half feet of merchantable timber in
that region and present indications
are that the efforts of this company
to place this vast body of timber on
the market will be crowned with sue
cess. Extracts from the bulletin is
sued by the department, regarding
the feasibility of the V shaped fiume
is as follows:
THAT the V-shaped timber f1ume is
a more efficient type than the box
or square-sided form is one of the
conclusions reached by the depart
ment of agriculture in bulletin just
issued on fumes and f1uming. The
V7shaped wooden fiume required less
water and, on the average, less
repairs than the other type is better
grades, and offers fewer chances for
jams. Concerning third type, the
sectional metal fume, semi-circular
in form, the prediction is made that
it will come into wide use. Such
fiume is strong and light and can
be quickly taken apart and trans
ported from one place to another to
be set up again.
when building fumes a good plan
says the department is to erect
small sawmill at or near the upper
end of the fiume location to saw out
the lumber needed for construction
Such material can be f1oated down
the fume as fast as the latter is
built and used for further extension.
For handling railroad cross-ties,
poles, cordwood, and the like, flume
with the sides of the 80 inches in
height is large enough. For handling
logs, piling, long timber or brailed
sawed lumber a height of from 40 to
so inches is recommended. The
best angle for the V is put at 80 de-

and the best results are obtained with |
grades between 2 and 10 per cent.
Abrupt curvatures in nume |
should be avoided, for they are likely
to cause jams. Curves should rarely |
be permitted to exceed 20 degrees.

adjuncts to the operation of fume. |
By their use a serious break or jam |
can be reported Immediately to the |
head of the flume to prevent further |
shipment of material. A telephone |
also makes it possible to notify the |
men at the upper end of the f1ume |

IS a good example of modern v !
shaped fume construction. This |
1ume, which is unusually large and |
,uilt to handle heavy logs and long |
imbers, is said to have cost approx
nately $4,000 per mile for the five
niles of its length, including the
;ost of constructing wagon road and
telephone equipment. Other fumes
