Bostock shows how the animal learns entirely by association, and not at all by the exercise of thought or reason, and yet a moment later says: "The animal is becoming amenable to the mastery of man, and in doing so his own reason is being developed," which is much like saying that when a man is practicing on the flying trapeze his wings are being developed. The lion learns slowly through association--through repeated sense impressions. First a long stick is put into his cage. If this is destroyed, it is replaced by another, until he gets used to it and tolerates its presence. Then he is gently rubbed with it at the hands of his keeper. He gets used to this and comes to like it. Then the stick is baited with a piece of meat, and in taking the meat the animal gets still better acquainted with the stick, and so ceases to fear it. When this stage is reached, the stick is shortened day by day, "until finally it is not much longer than the hand." The next step is to let the hand take the place of the stick in the stroking process. "This is a great step taken, for one of the most difficult things is to get any wild animal to allow himself to be touched with the human hand." After a time a collar with a chain attached is slipped around the lion's neck when he is asleep. He is now chained to one end of the cage. Then a chair is introduced into the cage; whereupon this king of beasts, whose reason is being developed, and who has such clear notions of inferior and superior, and who knows his own powers, usually springs for the chair, seeking to demolish it. His tether prevents his reaching it, and so in time he tolerates the chair. Then the trainer, after some preliminary feints, walks into the cage and seats himself in the chair. And so, inch by inch, as it were, the trainer gets control of the animal and subdues him to his purposes, not by appealing to his mind, for he has none, but by impressions upon his senses. "Leopards, panthers, and jaguars are all trained in much the same manner," and in putting them through their tricks one invariable order must be observed: "Each thing done one day must be done the next day in exactly the same way; there must be no deviation from the rule." Now we do not see in this fact the way of a thinking or reflecting being, but rather the way of a creature governed by instinct or unthinking intelligence. An animal never _learns_ a trick in the sense that man learns it, never sees through it or comprehends it, has no image of it in its mind, and no idea of the relations of the parts of it to one another; it does it by reason of repetition, as a creek wears its channel, and probably has no more self-knowledge or self-thought than the creek has. This, I think, is quite contrary to the popular notion of animal life and mentality, but it is the conclusion that I, at least, cannot avoid after making a study of the subject. II.
