For instance, there is a tribe in the vicinity of Lake Rudolph that
will eat no sheep or cattle, though its next neighbors do so. Near
by is another tribe that eats donkey-meat--a custom most revolting
to the surrounding tribes that do not eat donkey. So who may say
that it is nice to eat snails and frogs' legs and oysters, but
disgusting to feed upon grubs and beetles, or that a raw oyster,
hoof, horns, and tail, is less revolting than the sweet, clean meat
of a fresh-killed buck?

The next few days Tarzan devoted to the weaving of a barkcloth sail
with which to equip the canoe, for he despaired of being able to
teach the apes to wield the paddles, though he did manage to get
several of them to embark in the frail craft which he and Mugambi
paddled about inside the reef where the water was quite smooth.

During these trips he had placed paddles in their hands, when
they attempted to imitate the movements of him and Mugambi, but so
difficult is it for them long to concentrate upon a thing that he
soon saw that it would require weeks of patient training before they
would be able to make any effective use of these new implements,
if, in fact, they should ever do so.

There was one exception, however, and he was Akut. Almost from
the first he showed an interest in this new sport that revealed a
much higher plane of intelligence than that attained by any of his
tribe. He seemed to grasp the purpose of the paddles, and when
Tarzan saw that this was so he took much pains to explain in the
meagre language of the anthropoid how they might be used to the
best advantage.
