Ouakaris are generally caught in a very singular way. They are only found in a very small district on the southern bank of the Amazon River, and spend their whole lives in the topmost branches of the tallest trees, where it is quite impossible to follow them. And if they were shot with a gun, of course they would almost certainly be killed. So they are shot with a blowpipe instead. A slender arrow is dipped into a kind of poison called wourali, which has been diluted to about half its usual strength, and is then discharged at the animal from below. Only a very slight wound is caused, but the poison is still so strong that the ouakari soon faints, and falls from its perch in the branches. But the hunter, who is carefully watching, catches it in his arms as it falls, and puts a little salt into its mouth. This overcomes the effect of the poison, and very soon the little animal is as well as ever. Ouakaris which are caught in this way, however, are generally very bad-tempered, and the gentle and playful little animals sometimes seen in zoos have been taken when very young. They are very delicate creatures and nearly always die after a few weeks of confinement. THE COUXIA If you were to see a couxia, or black saki, as it is often called, the first thing that you would say would most likely be, "What an extraordinary beard!" And your next remark would be, "Why, it looks as if it were wearing a wig!" For its projecting black beard is as big as that of the most heavily bearded man you ever saw, while on its head is a great mass of long black hair, neatly parted in the middle, and hanging down on either side, so that it looks just like a wig which has been rather clumsily made. The couxia is extremely proud of its beard, and takes very great pains to prevent it from getting either dirty or wet. Do you remember how the diana monkey holds its beard with one hand while drinking, so as to keep it from touching the water? Well, the couxia is more careful still, for it will not put its lips to the water at all, but carries it to its mouth, a very little at a time, in the palm of its hand. But the odd thing is that it seems rather ashamed of thinking so much about its "personal appearance," and, if it knows that anybody is looking at it, will drink just like any other monkey, and pretend not to care at all about wetting its beard. Like most of the sakis, the couxia is not at all a good-tempered animal, and is apt to give way to sudden fits of fury. So savagely will it bite when enraged, that it has been known to drive its teeth deeply into a thick board. THE DOUROUCOULIS
