which at a good height would certainly cause their death. When
about two dozen pegs were made, one of them began cutting some
very long and slender bamboo from another clump, and also
prepared some cord from the hark of a small tree. They now drove
in a peg very firmly at about three feet from the ground, and
bringing one of the long bamboos, stood it upright close to the
tree, and bound it firmly to the two first pegs, by means of the
bark cord and small notches near the head of each peg. One of the
Dyaks now stood on the first peg and drove in a third, about
level with his face, to which he tied the bamboo in the same way,
and then mounted another step, standing on one foot, and holding
by the bamboo at the peg immediately above him, while he drove in
the next one. In this manner he ascended about twenty feet; when
the upright bamboo was becoming thin, another was handed up by
his companion, and this was joined by tying both bamboos to three
or four of the pegs. When this was also nearly ended, a third was
added, and shortly after, the lowest branches of the tree were
reached, along which the young Dyak scrambled, and soon sent the
Mias tumbling down headlong. I was exceedingly struck by the
ingenuity of this mode of climbing, and the admirable manner in
which the peculiar properties of the bamboo were made available.
The ladder itself was perfectly safe, since if any one peg were
loose or faulty, and gave way, the strain would be thrown on
several others above and below it. I now understood the use of
the line of bamboo pegs sticking in trees, which I had often
seen, and wondered for what purpose they could have been put
there. This animal was almost identical in size and appearance
with the one I had obtained at Semabang, and was the only other
male specimen of the Simia morio which I obtained. It is now in
the Derby Museum.
