That some fishes should leave the water and travel overland is, perhaps, not more remarkable than that some birds, the ouzel for example, should leave their natural element and fly into and under the water. Whoever knows the hidden paths of the marsh has doubtless watched the brown-hued Eels wriggling their way through the grass from one pool to another, especially at night, leaving their home and wandering about, seemingly unconscious whither their pilgrimage will end. “Slippery as an Eel” is proverbial. Many a person has, by his slick, cunning ways, succeeded in eluding the law and escaping justice, affording an apt illustration of the character of the animal about which we have been talking, but the slipperiness of the Eel is not given to it that it may take some unlawful advantage of its neighbors, but that it may the more readily slip from the grasp of a more powerful enemy, or the more easily make its way into the muddy depths of the pond or stream which it so very much affects. So it will be seen that while this slippery character in the one is protective, in the economy of nature, for a wise and laudable purpose, yet in the other it but secures to the possessor the getting of an ignoble gain and the ruin of a once proud name. While these agile denizens of aquatic life are selfish and voracious almost beyond precedent, and apparently more concerned in feeding than in anything else, there are certainly some traits in their character which are redeeming features. Low as they are in the scale of piscine existences, occupying the very lowest family of the Anguillidine Apodes, they are none the less susceptible to the human influence of kindness. They grow accustomed to man when good is at the basis of his actions, and have been known to accept food from his hand. They remember the face of a friend, and when it is presented at the door of glass, so to speak, that opens the way to their home, they come without fear or suspicion showing itself in their movements. Even the sound of the voice of a benefactor awakens a sympathetic response in their bosoms. RANA AND BUFO. Belonging to the lower vertebrates is a family of animals called scientifically Ranidæ, but which are, popularly speaking, best known as frogs. They are queer-looking creatures, scarcely met with in Australia and South America, but reaching their highest state in the East Indies. They are capable of enduring great changes of heat and cold, and can live on land as well as in water, provided they have the amount of moisture necessary to preserve the suppleness of their skins. Salt water is fatal to the frog in any stage of its existence.
