To Reduce the Gasoline Consumption of an Automobile
Quite recently I tried out a method of reducing the consumption of gasoline in my automobile, and, as a result, have higher efficiency without resorting to any of the numerous and exceedingly costly devices on the market.
I procured a piece of wire screen, cut it in the shape of the gasket between the carburetor and the intake manifold, but leaving it blind, that is, with the screen across the inlet. I put this between two gaskets and fastened the whole back in place. The result was an increase of 3 miles per gallon of fuel.—Contributed by W. J. Weber, New York City.
Cutting a Tin Ball from a Child's Finger
A three-year-old child found a globe of tin with a hole cut through the center, and—it is hardly necessary to state—immediately thrust his finger into the hole. But he could not get it out again, and the mother, accompanied by several other small children, brought the screaming child to my office. I found the hole had been punched, which caused three harpoon-like fragments to be carried into the center of the globe.
