SALT WATER MORE BUOYANT Fact That Is Well Known to Mariners May Be News to Some of Ou.-Readera. Ou.-Readera. A boy dropped a ball Into a small hole and could not get It out, so he poured water Into the hole, thinking the hall would float to the surface. As the ball was slightly heavier than the water wa-ter It remained on the bottom. Then the boy thought of mixing salt with the water, since he knew snlt water would float heavier objects than fresh water would. He tried this and was reward- ed with the floating ball. This particular fact is demonstrated at the mouths of rivers. Objects rolling roll-ing along the bottom of a river, too heavy to come to the top, will rlsn when carried out to sea. The rule also applies to boats. A Blilp with a cargo on the sea will sink sometimes a foot or two on entering a fresh water port. If she leaves the port with her cargo. he will rise on entering the ocenn. For mat Tetisef. a ship may be loaded apparently too heavily at a pier and still be all right on the waves. In building a dam, the fact of salt water's being heavier than fresh must be femenibered. Sum City Star.
