TO FIND THE NORTH
Of course you know ; that' iron will sink in water, because it is so . much heavier, but if it' is very small and highly polished, as in the form.of a new needle, you can lay it gently on the surface of a basin of water and it will float. If you will rub the needle with a toy magnet before placing it on the water, the needle will not only float, but will gradually ' work its way round until it lies due north and south. The north to which it points is the magnetic north, of course, and not the North Pole. - • ,
