In India there is a kind of otter which is often trained to catch fish for its master. It is taught, first of all, to pursue an imitation fish as it is drawn through the water by a string, and to bring it ashore and lay it down upon the ground. Then a dead fish is substituted for the false one, and when the otter has learned to bring this to its owner, and to give it up at the word of command, it is sent in pursuit of a live fish fastened to a line. And before very long it learns its duties so thoroughly that it will catch fish after fish, and bring them back without attempting to eat them, just as a well-trained retriever dog will bring back the birds or the rabbits which its master has shot. The otter of North America is still found, but not numerously, in the Carolinas and Florida, in some Rocky Mountain districts, in British Columbia and Alaska, and in the Canadian provinces. There is also a kind of otter which lives in the sea, and is called the sea-otter. It is also known as the kalan. It is found on the coasts of the Northern Pacific, and is much larger than the common otter, often weighing as much as seventy or eighty pounds, and being nearly four feet in total length. Its fur is the most costly known, a fine pelt being worth $600 or $800 before dressing. This high price is due partly to the beauty of the fur, but mainly to its rarity. CHAPTER XI THE BEAR TRIBE The bears are very interesting animals. In no animals, perhaps, are young folks more interested than in these, for they have many traits that endear them to little human admirers, while with older persons they have often lived on terms of intimate friendship. In our own country this interest in these fascinating animals was lately quickened, for children especially, by the almost universal possession and popularity among them of "Teddy bears," so named with playful reference to President Theodore Roosevelt, affectionately called "Teddy," and himself well acquainted with bears and other beasts, both wild and tame. POLAR BEARS One of the most interesting of all bears is the polar bear, which is found in almost all parts of the arctic regions. Sometimes it is called the white bear, on account of the color of its coat. But this is very seldom really white. Generally it is creamy yellow. And sometimes, in an old male, it is dingy yellow, and not even of the color of cream. This is one of the largest of the bears, for it often grows to a length of nine feet, and weighs eight hundred or even nine hundred pounds. Yet it is wonderfully active, and it can run with very great speed. Indeed, if it were to pursue a man, he would have very little chance of escape. But it is not at all a quarrelsome animal, and although it will fight most savagely if it is wounded or driven to bay, using both teeth and claws with terrible effect, it very seldom attacks if it is not molested.
