In spite of the greatest care it will sometimes happen under ordinary farm conditions that an occasional bad egg will appear among those sent to market. It would be wise to candle every egg shipped. Candling is “the process of testing eggs by passing light through them so as to reveal the condition of the contents.” A simple candling outfit may be made of an ordinary pasteboard box sufficiently large to be placed over a small hand lamp after the ends have been removed. The box should have a hole cut in it on a level with the flame of the lamp. Several notches should be cut in the edges on which the box rests, to supply air to the lamp. The box should be sufficiently large to prevent danger from catching fire. The one shown in figure 1 is made of corrugated pasteboard; ordinary pasteboard will serve the purpose. Candling is done in the dark, or at least away from strong light, and each egg is held against the hole in the side of the box, when its condition may be seen. An egg that shows any defect should not be marketed.
