Scores of times we have seen this quick change in temper take place in bears inhabiting our dens. Four bears will be quietly and peacefully consuming their bread and vegetables when,— "biff!" Like a stroke of lightning a hairy right arm shoots out and lands with a terriffic jolt on the head of a peaceful companion. The victim roars,—in surprise, pain and protest, and then a fight is on. The aggressor roars and bawls, and follows up his blow as if to exterminate his perfectly inoffensive cage-mate.

Mean and cruel visitors are fond of starting bear fights by throwing into the cages tempting bits of fruit, or peanuts; and sometimes a peach stone kills a valuable bear by getting jammed in the pyloric orifice of the stomach.

The owners of bears should NEVER allow visitors to throw food to them. Unlimited feeding by visitors will spoil the tempers of the best bears in the world.

Power of Expression in Bears. Next to the apes and monkeys, I regard bears as the most demonstrative of all wild animals. The average bear is proficient in the art of expression. The position of his ears, the pose of his head and neck, the mobility of his lips and his walking or his resting attitudes all tell their story.

To facial and bodily expression the bear adds his voice; and herein he surpasses most other wild animals! According to his mood he whines, he threatens, or warns by loud snorting. He roars with rage, and when in pain he cries, or he bawls and howls. In addition to this he threatens an enemy by snapping his jaws together with a mighty ominous clank, accompanied by a warning nasal whine. An angry bear will at times give a sudden rake with his claws to the ground, or the concrete on which he stands. Now, with all this facility for emotional expression, backed by an alert and many-sided mind, boundless energy and a playful disposition, is it strange that bears are among the most interesting animals in the world?

Bears in Captivity. With but few exceptions the bears of the world are animals with philosophic minds, and excellent reasoning power, though rarely equal to that of the elephant. One striking proof of this is the promptness with which adult animals accept comfortable captivity, and settle down in contentment. What we mean by comfortable captivity very shortly will be defined.

No bear should be kept in a cage with stone walls and an uneven floor; nor without a place to climb; and wherein life is a daily chapter of inactive and lonesome discomfort and unhappiness. The old-fashioned bear "pit" is an abomination of desolation, a sink- hole of misery, and all such means of bear torture should be banished from all civilized countries.

He who cannot make bears comfortable, contented and happy should not keep any.

A large collection of bears of many species properly installed may be relied upon to reveal many variations of temperament and mentality, from the sanguine and good-natured stoic to the hysterical demon. Captivity brings out many traits of character that in a wild state are either latent or absent.
