The fresh-laid egg is always desired for its delicious flavor, and this flavor changes but little in a week or two if the egg is kept cool. It is desirable to preserve eggs, however, for future use at the season when they are most abundant and cheap. Many methods have been tried, such as laying them away in sawdust, sinking them in water-glass solution, or coating the shell with paraffin or some other substance to prevent evaporation and the entrance of air. The introduction of cold storage on a large scale promises a solution of the problem. If eggs are fresh when placed in storage, it is possible to keep them just above the freezing temperature for months without appreciable deterioration.
Eggs too long in storage may be detected by the musty odor and flavor, the running of the yolk into the white, and the thin quality of the white which prevents beating stiff. Some states have already passed stringent laws in regard to the sale of cold storage eggs.
