OFFICIAL FOOD TESTS.
The United states and Canadian Gov ernments Analyse the Baking
 Powders.
Comparative Strength and Purity of the Different Brands omciaiiy
 Determined.
Prof Flames. Consulting Chemist of the Chicago Board of Health. Gives
 His Opinion.

The public is always responsiv,
 to suggestions about the food il
 eats. Great interest has been taker
 in the investigations made by ths
 United States and Canadian govern
 ments and by the different board.
 of health to show the purity or i'm
 purity of milk, baking powders
 spices, and other articles of daily
 use in the culinary department of
 our household.
 Just now the subject of baking
 powder is claiming public atten-
 ton. We all desire pure and whole
 some bread and this cannot be had
 with the use of impure or poisonous
 baking powder. There can be no longer any question that all the cheaper lowe grades of baking
 powders contain either alum, lime or phosphatie acid.
 The official analyses by the Uni ted States and Canadian govern ments have therefore been studied with interest and have pretty clear ly established the facts upon this subject. The United States gov ernment report gives the names of eighteen well-known powders, some of them advertised as pure cream of tartar baking powders, that contain alum.
 The report shows that the Royal baking powder was found the high est in leayening strength, evolving 1906 cubic inches of gas per single ounce of powder. There were eight other brands of cream oftartar pow ders tested and their average strength was 111.5 cubic inches of gas per ounce of powder.
 The Canadian government inves- tigations were of a still larger num- Der of powders. The Royal baking powder was here also shown the purest and highest in strength, con- 129.32 cubic inches of leav ening gas per ounce of powder. Nine other cream of tartar powders were tested, their average strength being reported to be S9 cubic inches of gas per ounce.
 These figures are very instructive to the practical housekeeper. They indicate that the Royal baking pow der goes more than B per cent. fur ther in use than the others, or is one-third more economical. Still more important than this, however, they prove this popular article has been brought to the highest degree of purity-for to its superlative puri- ty this superiority in strength is due-and consequently that by its use we may be insured the purest l and most wholesome food.
 The powders of lower strength are | found to leave large amounts of in ert matters in the food. This fact | is emphasized by the report of the Ohio State Food Commissioner, who, while finding the Royal practically | pure, found no other powder to con. tain less than 10 per cent. of inert or foreign matters.
 The public interest in this ques- ton has likewise caused to be made by our local authori- ties. Prof. w. $. Haines, of Rush College, consulting chem ist of the Chicago Board of Health, has found results similar to those by the national and Cana dian autorities. Dr. Haines says: RUSH MEDICAL COLLEGE, CHICAGO, ILL.
 have recently obtained samples of the chief baking powders in the market, and have subjected them to careful chemical examination to de- termine their purity, wholesome ness and leavening power. As the result of my tests I find the Royal baking powder superior to all the others in every respect. It is en- tirely free from all adulteration and impurity, and in bak- ing it gives off greater volume of gas than any other pow Ter. It is, therefore, not only the purest, but also the strongest pow Ter with which I am acquainted.

 The statistics show that there Is used in the manufacture of the Roy al baking powder more than half of all the cream of tartar consumed in the United States for the Royal baking powder-greater than that of all other baking powders com perhaps even higher evidence than that already quoted of the superiority of this article, and of its indispensableness to modern 
 Reorganization of the Ryland.
