A Dull Black for Cameras
Such parts of a camera that are apt to reflect light must be covered with a dull black. A mixture for this purpose is made of lampblack, about a teaspoonful, and enough gold size to make a paste as thick as putty. Add about twice the volume of turpentine and apply to the parts with a camel's-hair brush.
As the turpentine fumes are detrimental to the sensitive plate, the camera should be left open until these fumes have entirely disappeared.
A Door Fastener
Sometimes it is necessary to fasten a door in a manner to prevent children from opening it, yet so that it is easily opened from either side. This can be done by putting a screw or curtain hook on the inside of the door frame and using a piece of cord long enough to loop over both hooks. A person coming in or out can remove the loop from either side.—Contributed by John A. Cohalan, Philadelphia, Pa.
A floor wax can be made by melting 1 lb. of yellow beeswax in 1/2 pt. of hot, raw linseed oil; then adding 1 pt. of turpentine.
