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 suffi. cient water to rise to the extent of the 1sth of an inch around the base of the night light.
