MANY are the letters received in regard to the cereal breakfast foods, especially for children's use. One mother writes me: "Two small youngsters are anxiously awaiting your opinion in regard to their favorite shredded wheat, grape nuts, and post toasties." With few exceptions, a general statement will serve to give the facts in regard to all of the leading brands of cereal products and breakfast food's sold in packages. They are nutritious, cleanly products, containing the greater part of the nutriment of the grain and in some cases all of it. They are put up in a sanitary package and are convenient, and afford variety.
