The public is always responsive to suggestions
ABOUT the food II eats Great interest has been
taken in the Investigations made by the United
States and Canadian governments aud by the
different boards OF health, 10 show the purity or
impurity of milk, baking powders, Spices and
other articles of daily use in the culinary de-
partment of our households.
Just now the subject of baking powder is
Claiming public attention. We all desire pure and
wholesome 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, lower grades of baking powders con-
tain either alum. lime or phosphate acid.
The official analyses by the United States and
Canadian governments have therefore been
studied with interest and have pretty clearly
tablished the facts upon this subject. The
United States government 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 pow
der was found the highest in lesvening strength,
evolving 1905 cubic inches of gas per single
ounce OF powder. There were eight other
brands of cream of tartar powders tested, and
their average strength was ILLS cubic inches of
gas per ounce of powder.
The Canadian government investigations were
baking powder was here also shown the purest
and highest in strength, containing 1912 cubic
inches of leavenng gas per ounce OF powder.
Nine other cream of tartar powders were tested,
their average strength being reported to be SO
cubic inches Of gas per ounce.
These figures are very instructive to the prac-
teal housekeeper. They indicate that the
Royal baking powder goes more than 80 per
cent. further 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 degre e
of purity-for to its superlative purity this
superiority In strength Is due-and conse-
quently that by its use we may be insured the
purest and most wholesome food.
The powders OF lower strength are found to
leave large amounts of inert 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 contain less than IL per cent. of
inert or foreign matters.
The public interest in this question has like
wise caused to be made Investigations by our
local authorities. Professor w. 5. Haines, of
Rush Medical college, consulting chemist OF the
Chicago board of health, has found results
similar to those reported by the national and
Canadian authorities. DIR. Haines saws:
RUSH MEDICAL COLLEGE, CHICAGO, Ill.
have recently obtained samples of the chief
baking powders in the market, and have sub
jected them to careful chemical examination to
determine their purity, wholesomeness and
leayening power As the result of my tests
find the Royal baking powder superior 10 al the
others in every respect. IL is entirely free from
ali adulteraton and unwholesome impurity,
and in baking IL gives of greater volume of
leavening gas than any other powder. IL s.,
therefore, not only the pureSt, but also the
strongest powder with whiCh.I aIn acquinted.

The statistics show that there is used in the
manufacture of the Royal baking powder more
than half OF all the cream OF tartar consumed in
the United states for all purposes. Tine won
derlul sale thus indicated for the Royal baking
powder-greater than that OF all other baking
powders combined-is perhaps even a higher
evidence than that already quoted of the supe-
riority of this article, aud OF its Indispensable
ness to modern cookery.
