The origin of the investigation of the preparation of frozen and dried eggs has been set forth in Circular 98 2 of the Bureau of Chemistry. The need, from an economic viewpoint as well as that of wholesomeness, for the conservation of certain eggs out of their shells is also discussed in the circular cited. In the pursuance of the plan of work therein outlined, a study has been made of the various types of eggs going to the egg-breaking establishments in the egg-producing section. The results of this part of the investigation are given in Bulletin 51 of the Department of Agriculture. The next step in logical sequence would be a study of the conditions prevailing in egg-breaking houses and the quality of the product sent into commerce. In the preliminary survey of the problem, as given in Circ
