nd
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.

I afterwards shot two adult females and two young ones of different
ages, all of which I preserved. One of the females, with several young
ones, was feeding on a Durian tree with unripe fruit; and as soon as she
saw us she began breaking off branches and the great spiny fruits
with every appearance of rage, causing such a shower of missiles as
effectually kept us from approaching too near the tree. This habit of
throwing down branches when irritated has been doubted, but I have, as
here narrated, observed it myself on at least three separate occasions.
It was however always the female Arias who behaved in this way, and
it may be that the male, trusting more to his great strength and his
powerful canine teeth, is not afraid of any other animal, and does not
want to drive them away, while the parental instinct of the female leads
her to adopt this mode of defending herself and her young ones.

In preparing the skins and skeletons of these animals, I was much
troubled by the Dyak dogs, which, being always kept in a state of
semi-starvation, are ravenous for animal food. I had a great iron pan,
in which I boiled the bones to make skeletons, and at night I covered
this over with boards, and put heavy stones upon it; but
