Now it is true that it takes more than one generation for any wild creature to get completely away from its natural timidity. Quite often a person is met who has taken quail eggs from a nest and hatched them beneath the warm body of a domestic hen. Just what is the value of such a proceeding is rather hard to explain, as quail have neither the instincts nor the training to enjoy life in a barnyard. Yet occasionally it is done, and the little quail spend most of their days running frantically up and down the coop, yearning for the wild, free spaces for which they were created. But they haven't, as a rule, many days to spend in this manner. Mostly they run until they die.
The rule is said to work both ways. A tame canary, freed, will usually try to return to his cage. And this is known to be true of human beings just as of the wild creatures. There are certain breeds of men, used to the far-lying hills, who, if inclosed in cities, run up and down them until they die. The Indians, for instance, haven't ever been able to adjust themselves to civilization. There are several thousand of them now where once were millions.
Bushy-tail was not particularly afraid of the human beings that passed up and down the park, because he had learned by experience that they usually attempted no harm to him. But, nevertheless, he had his instincts. He didn't entirely trust them. Occasionally a child would come with a bag of nuts, and he would sit on the grass not a dozen feet away to gather such as were thrown to him. But all the time he kept one sharp eye open for any sudden or dangerous motions. And every instinct warned him against coming nearer than a dozen feet. After several generations, probably the squirrels of this park would climb all over its visitors and sniff in their ears and investigate the back of their necks. But this wasn't the way of Bushy-tail. He had come too recently from the wild places. And he wondered, most intensely, whether this tall, forked creature had a pocket full of nuts. He swung down on the grass to see.
"Why, you little devil!" Dan said in a whisper. His eyes suddenly sparkled with delight. And he forgot all about the doctor's words and his own prospects in his bitter regrets that he had not brought a pocketful of nuts. Unfortunately, he had never acquired the peanut habit. His mother had always thought it vulgar.
And then Dan did a curious thing. Even later, he didn't know why he did it, or what gave him the idea that he could decoy the squirrel up to him by doing it. That was his only purpose,—just to see how close the squirrel would come to him. He thought he would like to look into the bright eyes at close range. All he did was suddenly to freeze into one position,—in an instant rendered as motionless as the rather questionable-looking stone stork that was perched on the fountain.
He didn't know it, at the time, but it was a most meritorious piece of work. The truth was that he was acting solely by instinct. Men who have lived long in the wilderness learn a very important secret in dealing with wild animals. They know, in the first place, that intimacy with them is solely a matter of sitting still and making no sudden motions. It is motion, not shape, that frightens them. If a hunter is among a herd of deer and wishes to pick the bucks off, one by one, he simply sits still, moving his rifle with infinite caution, and the animal intelligence does not extend far enough to interpret him as an enemy. Instead of being afraid, the deer are usually only curious.
Dan simply sat still. The squirrel was very close to him, and Dan seemed to know by instinct that the movement of a single muscle would give him away. So he sat as if he were posing before a photographer's camera. The fact that he was able to do it is in itself important. It is considerably easier to exercise with dumb-bells for five minutes than to sit absolutely without motion for the same length of time. Hunters and naturalists acquire the art with training. It was therefore rather curious that Dan succeeded so well the first time he tried it. He had sense enough to relax first, before he froze. Thus he didn't put such a severe strain on his muscles. And this was another bit of wisdom that in a tenderfoot would have caused much wonder in certain hairy old hunters in the West.
The squirrel, after ten seconds had elapsed, stood on his haunches to see better. First he looked a long time with his left eye. Then he turned his head and looked very carefully with his right. Then he backed off a short distance and tried to get a focus with both. Then he came some half-dozen steps nearer.
A moment before he had been certain that a living creature—in fact one of the most terrible and powerful living creatures in the world—had been sitting on the park bench. Now his poor little brain was completely addled. He was entirely ready to believe that his eyes had deceived him.
All the time, Dan was sitting in perfectly plain sight. It wasn't as if he were hiding. But the squirrel had learned to judge all life by its motion alone, and he was completely at a loss to interpret or understand a motionless figure.
