A
canvas yoke was first cut out to the form shown in Fig. 213. We used two
thicknesses of the heaviest brown canvas we could find, binding the two
pieces together with tape. The yoke was padded with cotton at the
shoulders and a strap was fastened to each shoulder piece. These were
arranged to be buckled to a pair of straps fastened to the back of the
yoke and passing under the arms. Riveted to these straps were a pair of
straps used for fastening on the pack. The yoke straps were attached with
the rough side against the yoke, while the pack straps were riveted on
with the rough side uppermost, as indicated in the drawing.

Riveting.
[Illustration: Fig. 214. Riveting the Straps Together.]
The method of riveting together the leather straps may need a word of
explanation. A copper rivet was passed through a hole in the two straps;
then the washer was slipped over the projecting end of the rivet. This
washer had to be jammed down tight against the leather, and to do this we
drilled a hole of the diameter of the rivet in a block of wood, and
putting this block over the washer, with the end of the rivet projecting
into the hole, we hammered the block until the washer was forced down
tight against the leather.
