purpose.

such as are used for enameling bathtubs. After this has dried,
smooth it off with pumice stone and water. To keep the metal from

** Self-Lighting Arc Searchlight [9]

A practical and easily constructed self-lighting arc searchlight
can be made in the following manner: Procure a large can, about 6
in. in diameter, and cut three holes in its side about 2 in. from
