No doubt most of you have foundpleasure in the possession of one of those redhorseshoe magnets which are sold in many toy-stores. But the picture here given representsa natural iron ore found in Magnet Cove, Arkan-sas, which is far more powerful than the artificialmagnets with which you have played, as can beseen by a glance at the number of nails that areattracted to it by its natural magnetism. It isfound in great abundance in the above-namedlocality, where it is mined for the iron it con-tains. Very strong natural magnets are also found inthe Ural and other mountains of the Old Chamberlain. ioio.] NATURE AND SCIENCE FOR YOUNG FOLKS 941 AN ELEPHANTS
