The young lion spends much time in pretended stalking of game and in harmless struggles with his mates. He takes great delight in the exercise of his cunning and in his strength of limb and jaw. Fortunately for the young lion this is the sort of activity best adapted to develop his strength of muscle and his cunning in capturing prey. However, it is not for the sake of the training that the young lion performs these particular acts. He does them simply because he loves to. In like manner the young greyhound chasing his mates and the young squirrel gathering and storing nuts have no thought beyond the instinctive pleasure they find in performing these functions. To each there is no other form of activity so satisfactory. Man possesses more instincts than any of the lower animals. One pronounced instinct in all normal males is the hunting instinct. Grover Cleveland went fishing because he loved the sport, not because of the value of <p 189> the fish caught. Theodore Roosevelt did not hunt big game in Africa because he was in need of luscious steaks or tawny hides. He was not working solely in the interest of the Smithsonian Institute nor to secure material for his book. Doubtless these were subsidiary motives, but the chief reason why he killed the game was that he instinctively loves the sport. He endured the hardships of Africa for the same reason that fishermen spend days in the icy water of a trout stream and hunters lie still for hours suffering intense cold for a chance to shoot at a bear. _For some men, buying and selling is as great a delight as felling a deer. For others the manufacture of goods is as great a joy as landing a trout. For such a man enthusiasm for his work is unfailing and industry unremittent_. He is suited to his task as is the cub to the fight, the puppy to the chase, the squirrel to the burying of nuts, or the hunter to the killing of game. His labor always appeals to him as the thing of supremest moment. His interest in it is such that it never fails to in- <p 190> spire others by contagion. For such a man laziness or indifference in business seems anomalous, while industry and enthusiasm are as natural as the air he breathes and as inexhaustible as the air itself. By classifying the love of the game as an instinct, we seem to admit that it is born and not developed; that some men possess it and others do not; that if a man possesses it, he does not need to cultivate it, and that if he does not possess, he cannot acquire it. There is doubtless much truth in this, but fortunately it is not the whole truth. Some instincts are specific--even stereotyped --and not subject to cultivation or change. Thus the bee's instinctive method of gathering and storing honey is very specific and definite. The bee is unable to modify its routine to any great extent. The bee which does not instinctively perform the different acts properly will never learn to.
