"Half Pound Free."

Old Bones, Alum, Flint and Sulphuric Acid for Raising Food.

Good housewives have been surprised lately to receive an invitation signed with their grocer's name to step in and get a half-pound of an alleged baking powder free. This is another scheme of some baking powder fiend to get his goods upon the market.

Housekeepers should be on their guard against all such schemes as these. Alum baking powders are generally low priced, but they are well-known to be detrimental to health. Large quantities of one of them were recently seized in New York, being found to be one-quarter sharp-pointed grains of ground flint. Most of the so-called phosphate powders are mixed with alum. The manufacturer of a phosphate powder, at Providence, R.I., has patented the process of making the principal ingredients of his powder from bones digested with sulphuric acid.

Housekeepers do not want such mixtures in their food. They should never encourage peddlers nor admit testers or alleged experimenters in food within their doors, and when buying baking powder should get the well-known cream of tartar goods, which are made from the pure and healthful grape.
