rest; but when about ten of them had thus ventured separately, they began to come in small groups, leaving the others rolling and jumping on the sand.... It was not {256}long before two males--the same, I had no doubt, which we had noticed before--came and squatted themselves one on each side of the little creek.... Crack went my rifle. But instead of either of them dropping, the two Baboons started up; by a mutual instinct they both clutched their noses, gave a ringing bark and scampered off. The whole herd took the alarm, and joining in the shrieking clamour were soon lost to sight." On another occasion Dr. Holub and his servant had a _rencontre_ with a herd of Baboons. He writes:--"We caught sight of them in one of the glens. They were on the further side, and being anxious to obtain a specimen of their skulls, I fired and killed one Baboon; but unfortunately for me, the creature fell into the river. At my second shot I wounded two more. This induced the right wing of the herd to retreat; but the main body kept their ground, and the left flank, moreover, assumed the aggressive, and commenced pelting us so vigorously with stones, that, remembering that I had only one cartridge, I considered it far more prudent to withdraw than to run the risk of a hand-to-hand encounter." On a still further occasion the same well-known traveller says: "I was turning to leave the ravine when some stones came pattering down the rocks in my direction. I soon became aware that the stones were being designedly aimed at me; and, looking up, I saw a herd of Baboons." "The Nyanyi or Cynocephalus," writes Sir Richard Burton in his "Lake Regions of Central Africa," "in the jungles of Usukuma attains the size of a Greyhound, and, according to the natives, there are three varieties of colour--red, black and yellow. They are the terror of the neighbouring districts; women never dare to approach their haunts; they set the {257}Leopard at defiance, and when in a large body, they do not, it is said, fear the Lion."
