the four winds of heaven and the portion of it exposed to the rays of the sun would become more highly heated than that part of the surface exposed to the north and its cold wind. The ball would be more apt to become heated during the day than would the base upon which it rests, as the latter is larger and heavier than the ball. If one part of the ball expands a minute quantity more than the other, with each heating of one side, and contracts in the same ratio upon cooling, there would result a slight creeping movement which in time would move the ball sufficiently to make its change of position noticeable to the eye. Naturally the expansion of one side of the ball Iwould make that side heavier than the chilled portion, and the heated part would work its way to the bottom. THE BALL ON THIS MONUMENT, WEIGHING OVER TWO TONS, TURNS AROUND OF ITS OWN ACCORD. MONUMENT THAT MOVES SEVERAL years ago the very hand some monument shown in the illustration was erected to the memory of a citizen of Marion, Ohio. The base of the stone was unpolished granite but the ball upon the top was so highly polished that it reflected surrounding objects. The stone-cutter had left but one spot upon the surface of the ball unpolished, where it came in contact with the base. In spite of the fact that the ball is 36 inches in diameter and weighs 4,200 pounds, after the erection of the monument a visitor was astonished to find that the ball had shifted its position and the rough spot was clearly visible at one side. The cemetery authorities were consulted and were confident that the ball had not been moved by human aid and the shifting of its position was at first attributed to movements of the earth. The controversy attracted such widespread attention that a number of scientists came to Marion to investigate. They were told that in spite of all effort on the part of the cemetery employes the ball persisted in turning. The following conclusion was reached: As a sphere, its surface is presented to OUR NEW DREADNAUGHT, THE Utah. This 22.000 ton battleship was brought from the yards at Camden, N.

But unfortunately electricity is not to be found everywhere, and consequently the invention of the mechanical brush, for which electrical power is not needed is likely to prove of great utility. This ingenious little contrivance will enable one to clean floors with much less trouble than heretofore. The old method employed in France of rubbing the floor by means of the foot is very difficult, for the person rubbing not only has to do the work but also to expend considerable energy in keeping his balance. The mechanical brush as shown by our photograph is composed of a rather heavy frame which is placed on the floor. This frame carries a brush placed at the OPERATING THE BRUSHES THAT CLEAN THE INLAID FLOOR-A FRENCH INVENTION. WHERE HORSES ARE NOT ALLOWED TO GO.

The dog was sent to the hospital. At the end of three weeks it was discharged as "cured." For treatment, service, meals, etc., the total cost in this case was but four dollars, A GIGANTIC ROOSTER THAT COMMANDED A PROMI- It was built on a large scale and the effect was |
