SCOUTING, JANUARY 15, 1920
bers piled on the floor and repiled on the
opposite bank without the use of the cart.
The timbers used shall be of the dimen-
sions specified herewith, and the lashings
made as in Figure 4 beginning with clove
hitch at (1) on the end of the lower
timber. (This lashing is made by bring-
ing the rope over the upper timber to
(2A), under the lower timber (2B), over
the upper at (2C), and under the lower
at (2D) to place of beginning, and mak-
ing four complete turns in thia^vay, the
under laps coming on the inside, the
upper laps on the outside on each turn,
the ropes never crossing each other. They
must be kept taut at all points. The lash-
ing is completed with two frapping turns
(3) around the lashing between the tim-
bers. Draw very taut and finish with a
clove hitch (4) on the end of the upper
timber. The success of this lashing de-
pends on keeping the rope taut during
the entire process.) The inclined mem-
bers must be placed as indicated in the
profile drawing at the top of this page
with the cross braces on the upper side
of the incline, except that one end of one
cross brace is on the under side, so that
the cross braces can pass each other at
the center of the " X" which they make
without warping. The lower one of the
horizontal members (1) is underneath the
incline; the upper (3) is on the top side.
The center unit is made with the
stringers (5) underneath two flooring
members (8). The ends of the stringers
come inside the upper ends of the inclined
members as indicated at (5) in Figure 2,
which is the position of (5) in Figure 3.
The lowest flooring member on the
ramps on each shore is lashed to the
stringer, but except for the two flooring
members on the center piece, none of
the rest of the flooring is lashed for pur-
poses of this contest.
The score of a troop
will be the working time
from the word " Go " un-
til the troop is at atten-
tion on the left bank with
the bridge completed, plus
the time from the second
word " Go" until it is at
attention with the bridge
demounted on the right
bank, plus time penalties
as follows:
For each incorrect lash-
ing (less than 4 main
raps and 2 frapping raps
or looseness of lashing),
1 minute. For each tim-
ber incorrectly placed, re-
ferring particularly to
timbers (5) of the center
unit in relation to the
inclined units and to timb-
ers (4) in the inclined
units, 1 minute. For each
boy falling into the stream,
stepping inside the lines
marking the edge of the
stream, 30 seconds. For allowing floor-
ing to fall into the stream, either build-
ing or demounting, each instance but not
each stick in each instance, 15 seconds.
Scores in Public Competitions
AS the object of all work of the Pine
Tree type is snappy and precise drill
with standard equipment, and as this is the
finest type of recruiting publicity for the
Boy Scout Movement, the honor of reduc-
ing the national score for the Pine Tree
bridge will be contingent upon the cer-
tificate of the troop committee that these
standards were faithfully fulfilled by two
patrols from the same troop not particu-
larly arranged for the competition, judged
by themselves and one associate at a pub-
lic entertainment or demonstration or
competition.
Materials
Measurements of timbers are, of
course, approximate. Diameters re-
fer to the small end of the stick. It is
desirable that tamarack or spruce be used
because of their lightness and strength.
Hard woods are equally useful but heavier
to transport. Sassafras or black ash
would answer, both being light of weight
when dry. Shallow notches may be made
on each timber at the bearing point no
wider than the timber is to receive. This
will make a firmer bearing and will help
quickly to locate the points for lashing.
Timbers may be numbered either by paint-
ing or burning. The measurements are
as follows:
(2) Inclined Members Figure 2.—No.
1, 2 pieces 2 in. x 5 ft. 2 in. ledgers; No.
2, 4 pieces 2 in. x 5 ft. spars; No. 3, 2
pieces 2 in. x 4 ft. 6 in. transoms; No. 4,
4 pieces 1% in. x 5 ft. 8 in. cross braces.
(1) Horizontal Member Figure 3.—
No. 5, 2 pieces 2y2 in. x 5 ft. 6 in. string-
ers; No. 8, 2 pieces 2 in. x 4 ft. 8 in.
cross ties.
(2) Ramps.—No. 6, 4 pieces 2^ in. x
7 ft. 6 in. ramp stringers.
Flooring.—No. 7, 80 pieces (more or
less) 2y2 in. x 4 ft.
For rope, 5/16 in. manilla is desirable.
A good quality of twisted clothes-line will
do. Soft braided cotton clothes-line
stretches so it is useless. All ropes should
be cut to length and have both ends
lashed. The lashing specified is the stand-

ard form used by military and naval engi-
neers and is the strongest method of
lashing timbers known.
SCOUTING is indebted to the Wood-
crafter of the Flint, Mich., Council,
Mr. N. C. Webster, for the working out
of the details for this standard bridge.
Since the bridge itself was tried out at
the Flint Camp last summer, the drill
has been tried and Mr. Webster recom-
mends the following procedure:
Four scouts unload the spars, ledger
and transom for one inclined member,
Fig. 2, on ohe side of the cart and begin
lashing. Four other scouts doing the
same with the other inclined members on
the other side of cart. Two scouts unload
and lash top member, Fig. 3, in rear of
cart. Two scouts each lash first piece of
flooring on lower end of ramp stringers.
This accounts for twelve scouts who will
each have two lashings to make, leaving
four scouts to unload the braces, flooring
and placing flooring in a convenient loca-
tion for putting on the bridge. Bridge
now ready for erecting.
The first inclined member finished will
be " floated " across the " stream " by the
team that tied it and received by two of
the scouts who were unloading who have
pole-vaulted the "stream." Team crosses
in the same way and holds inclined mem-
ber, Fig. 2, in position to receive top
member, Fig. 3, which is guided to its
place by the first two scouts over with
ramp stringers projected over the top of
the inclined member. The team on the
first side of the stream then lock their
inclined member into the top member, Fig.
3. The ramps are then put in place by the
scouts who tied them, the one first fin-
ished having been " floated" across in
same manner as the inclined member.
There are now eight scouts on each side
of the bridge. The fours who tied each
inclined member will lay flooring from
each side of the bridge, two on top and
two on the ramps on each side, the others
passing the flooring to them.
THERE are wonderful possibilities for
fun in this splendid idea. There are
days gathering material, evening hours
whipping the ropes and practicing the
lashing, patrol tryouts for the honor of
a place on the troop team,
and the demonstration is
one that not only appeals
to the boys, but gives
Scouting the most desir-
able kind of publicity in a
community.
When you work out the
ideal procedure and estab-
lish the quickest way of
doing this, or when you
find points in judging
which have been over-
looked in the tryouts al-
ready made, contribute
them to the end of accom-
plishing a standard time
competition in which all
troops, alone or under
council, wherever located,
may compete in a typical
Boy Scout engineering ac-
tivity.
Meanwhile, do not over-
look the value of making
small models of this
bridge—such as those il-
lustrated in the last issue of Scouting,
and framing them with drawings or
photographic enlargements of your camp-
ing places. The big bridge has its thrills,
it is the racing model. The miniature has
its charm. It is the advertising model,
everlastingly at it in store windows,
church and school halls, and at troop or
council headquarters.
Occasionally, too, there is a chance to
build a camp bridge.
