Field's and Child's night lights are generally known and are easily
obtainable. But under circumstances where they cannot be procured, the
waste of candles may be thus applied. Make a _fine_ cotton, and wax it
with white wax. Then cut into the requisite lengths. Melt the grease
and pour into pill boxes, previously either fixing the cotton in the
centre, or dropping it in just before the grease sets. If a little
white wax be melted with the grease, all the better. In this manner,
the ends and drippings of candles may be used up. When set to burn,
place in a saucer, with sufficient water to rise to the extent of the
16th of an inch around the base of the night light.
