Quotation from: The Beasts of Tarzan

Written by: Edgar Rice Burroughs

"They may and they may not," replied the ape-man. "They have been
ill at ease since they were forced to accept so many human beings
into their confidence. Mugambi and I alone affected them less,
for he and I are, at best, but half human. You, however, and the
members of the crew are far too civilized for my beasts--it is
you whom they are fleeing. Doubtless they feel that they cannot
trust themselves in the close vicinity of so much perfectly good
food without the danger that they may help themselves to a mouthful
some time by mistake."
