In 1910 there arose in the United States of America a group of professional college-and-university animal psychologists who set up the study of "animal behavior." They did this so seriously, and so determinedly, that one of the first acts of two of them consisted in joyously brushing aside as of no account whatever, and quite beneath serious consideration, everything that had been seen, done and said previous to the rise of their group, and the laboratory Problem Box. In view of what this group has accomplished since 1910, with their "problem boxes," their "mazes" and their millions of "trials by error," expressed in solid pages of figures, the world of animal lovers is entitled to smile tolerantly upon the cheerful assumptions of ten years ago. But let it not at any time be assumed that we are destitute of problem boxes; for the author has two of his own! One is called the Great Outdoors, and the other is named the New York Zoological Park. The first has been in use sixty years, the latter twenty-two years. Both are today in good working order, but the former is not quite as good as new. A Preachment to the Student. In studying the wild-animal mind, the boundary line between Reality and Dreamland is mighty easy to cross. He who easily yields to seductive reasoning, and the call of the wild imagination, soon will become a dreamer of dreams and a seer of visions of things that never occurred. The temptation to place upon the simple acts of animals the most complex and far- fetched interpretations is a trap ever ready for the feet of the unwary. It is better to see nothing than to see a lot of things that are not true. In the study of animals, we have long insisted that _to the open eye and the thinking brain, truth is stranger than fiction._ But Truth does not always wear her heart upon her sleeve for zanies to peck at. Unfortunately there are millions of men who go through the world looking at animals, but not seeing them. Beware of setting up for wild animals impossible mental and moral standards. The student must not deceive himself by overestimating mental values. If an estimate must be made, make it under the mark of truth rather than above it. While avoiding the folly of idealism, we also must shun the ways of the narrow mind, and the eyes that refuse to see the truth. Wild animals are not superhuman demigods of wisdom; but neither are they idiots, unable to reason from cause to effect along the simple lines that vitally affect their existence. Brain-owning wild animals are not mere machines of flesh and blood, set agoing by the accident of birth, and running for life on the narrow-gauge railway of Heredity. They are not "Machines in Fur and Feathers," as one naturalist once tried to make the world believe them to be. Some animals have more intelligence than some men; and some have far better morals.
