The most rigidly conducted chase has something of the character of play, and there is a whole cycle of games in which flight and pursuit are the main features. To begin with the pursuit of our own kind: suppose one taking a two-year-old child in his arms and springing toward another person, who runs away in pretended fright. The child will manifest delight, which is much too strong to be attributed to mere pleasure in the movement, and must be connected with the hunting impulse. It is shown, too, quite as plainly by boys playing on the street. James is right when he says, “A boy can no more help running after another boy who runs provokingly near him than a kitten can help running after a rolling ball.”[486] In 1894 I had an opportunity to observe a scene which displayed the power of this instinct in a manner which was almost terrible; the boys irresistibly reminded me of dogs or wolves pursuing their prey in a hot chase. At that time a racer came to Giessen, and to attract attention ran through the streets at midday attired in rose-coloured tights, fantastically decorated, and carrying a large bell in his hand. He moved with incredible rapidity, now disappearing round some corner, and now emerging from a side street. When school was out a crowd of homeward-bound boys filled the streets, and, catching sight of the runner, chased after him, so that soon a mob of from fifty to one hundred children were on his heels, chasing him like a pack of hounds with the wildest excitement and loud cries. The man carried a whip which he laid about him well, otherwise the children would doubtless have tried to catch and beat him.
