The Florida crocodile is the shrewdest species of all those I know personally. It has the strange habit of digging out deep and spacious burrows for concealment, in the perpendicular sandy banks of southern Florida rivers where the deep water comes right up to the shore. Starting well under low-water mark, the crock digs in the yielding sand, straight into the bank, a roomy subterranean chamber. In this snug retreat he once was safe from all his enemies,--until the fatal day when his secret was discovered, and revealed to a grasping world. Since that time, the Alligator Joes of Palm Beach and Miami have made a business of personally conducting parties of northern visitors, at $50 per catch, to witness the adventure of catching a nine-foot crocodile alive. The dens are located by probing the sand with long iron rods. A rope noose is set over the den's entrance, and when all is ready, a confederate probes the crocodile out of its den and into the fatal noose. Today the Florida crocodile is so nearly extinct that it required two years of diligent inquiry to produce one live specimen subject to purchase. Common Sense in the Common Toad. Last spring, in planting a lot of trees on our lawn, a round tree-hole that stood for several days unoccupied finally accumulated about a dozen toads. Its two feet of straight depth was unscalable, and when finally discovered the toads were tired of their imprisonment. Partly as a test of their common-sense, Mr. George T. Fielding placed a six-inch board in the hole, at an angle of about thirty degrees, but fairly leading out of the trap. In very quick time the toads recognized the possibilities of the inclined plane and hopped upward to liberty. In the use of this opportunity they showed more wisdom than our mountain sheep manifest concerning the same kind of an improvement designed to enable them to reach the roof of their building. XVII THE TRAINING OF WILD ANIMALS Before we enter this chapter let us pause a moment on the threshold, and consider the logic of animal training and performances. Logic is only another name for reason. Its reverse side is fanaticism; and that way madness lies. It is the duty of every sane man and woman to consider the cold logic of every question affecting the welfare of man and nature. Fanaticism when carried to extremes can become a misdemeanor or a crime. The soft-hearted fanaticism of humanics that saves a brutal murderer, or would-be murderer like Berkman, from the gallows or the chair, and eventually turns him loose to commit more crimes against innocent people, is not only wrong, and wicked, but in aggravated cases it is a _crime_ against society.
