Robber And Robbed
TORRES SLEPT for about half an hour, and then there was a noise among the trees--a sound of light footsteps, as though some visitor was walking with naked feet, and taking all the precaution he could lest he should be heard. To have put himself on guard against any suspicious approach would have been the first care of our adventurer had his eyes been open at the time. But he had not then awoke, and what advanced was able to arrive in his presence, at ten paces from the tree, without being perceived.

It was not a man at all, it was a "guariba."

?Of all the prehensile-tailed monkeys which haunt the forests of the Upper Amazon--graceful sahuis, horned sapajous, gray-coated monos, sagouins which seem to wear a mask on their grimacing faces--the guariba is without doubt the most eccentric. Of sociable disposition, and not very savage, differing therein very greatly from the mucura, who is as ferocious as he is foul, he delights in company, and generally travels in troops. It was he whose presence had been signaled from afar by the monotonous concert of voices, so like the psalm-singing of some church choir. But if nature has not made him vicious, it is none the less necessary to attack him with caution, and under any circumstances a sleeping traveler ought not to leave himself exposed, lest a guariba should surprise him when he is not in a position to defend himself.
