Among the fishes there is one murderer whose evil reputation is well deserved. The common swordfish of the Atlantic, forty miles or so off Block Island or Montauk Point, is not only one of the most fearless of all fishes, but it also is the most dangerous. His fierce attacks upon the boats of men who have harpooned him and seek to kill him are well known, and his unparalleled courage fairly challenges our wonder and admiration. But, unfortunately, the record of the swordfish is stained with crime. When the spirit of murder prompts him to commit a crime in sheer wantonness, he will attack a whale, stab the unfortunate monster again and again, and pursue it until it is dead. This is prompted solely by brutality and murder lust, for the swordfish feeds upon fish, and never attempts to eat any portion of a whale. It can easily be proved that wild animals in a normal state of nature are by no means as much given to murder, either of their own kind or other kinds, as are many races of men. The infrequency of animal murders cannot be due wholly to the many possibilities for the intended victim to escape, nor to difficulty in killing. In every wild species murders are abundantly possible; but it is wholly against the laws of nature for free wild beasts to kill one another in wantonness. It is left to the savage races of men to commit murders without cause, and to destroy one another by fire. The family crimes and cruelties of people both civilized and savage completely eclipse in blackness and in number the doings of even the worst wild beasts. In wild animals and in men, crime is an index to character. The finest species of animals and the noblest races of men are alike distinguished by their abhorrence of the abuse of the helpless and the shedding of innocent blood. The lion, the elephant, the wild horse, the grizzly bear, the orang-utan, the eagle and the whooping crane are singularly free from the criminal instinct. On the other hand, even today Africa contains tribes whose members are actually fond of practicing cruelty and murder. In the Dark Continent there has lived many a "king" beside whom a hungry lion or a grizzly bear is a noble citizen. XXV FIGHTING WITH WILD ANIMALS The study of the intelligence and temperaments of wild animals is by no means a pursuit of academic interest only. Men now are mixing up with dangerous wild beasts far more extensively than ever before, and many times a life or death issue hangs upon the man's understanding of the animal mind. I could cite a long and gruesome list of trainers, keepers and park owners who have been killed by the animals they did not correctly understand.
