and the arm of the lever is depressed, the auxiliary valve opens and allows a free flow of gas to pass through the nozzle. Conversely, of course, when the utensil is removed, the weight throws the arm of the lever up again and the valve is nearly closed, allowing only a minute quantity of gas to pass through. The quantity of gas allowed to pass through the auxiliary valve when no utensil is on the range is regulated by the screw which operates on the under side of the lever and lifts, or allows the weight to drop, according to whether it is screwed up or unscrewed. The economy of the device is obvious. None but the very careful housekeeper, who values her time far and away below the price of gas, turns down the gas every time a cooking utensil or iron is removed, when it is her intention that it shall be replaced by another, yet it is astonishing how much gas is wasted in the interim between the removal of one utensil and the putting on of another. The device described effectually obviates this. SAFETY RAZOR BLADES CAN BE MADE INTO GOOD KNIVES FOR THE HOUSEWIFE the safety razor for ripping seams.

If you will take two pieces of tin soldered at the end, and tack them on either side of the brush below the bristles, you will have a little cup which catches this overflow paint. Every time the brush is dipped into the paint can, the shield is automatically emptied. C. H.
