state, the circular being headed in large letters, ‘Tomato Pulp for Sale,’ 
and advertising some twelve different grades for use in making catsups.” 
“ One hundred barrels of old goods, made partly from whole stock and 
partly waste, boiled down nearly to catsup thickness, has preservalin in it, 
fine goods, but some of it is fermented; packed in good oak whisky and 
wine barrels. Price $2 per barrel. ” 
‘ ‘ Two hundred and twenty-five barrels new goods made from waste, 
has benzoate of soda in it; packed in good whisky and wine barrels, at $3 
per barrel, net cash.” 
‘‘Three hundred barrels old goods, partly whole stock, partly waste, 
has salicylic acid in it; nice goods, but some of it is fermented. Price $2 
per barrel. ” 
‘‘Four hundred barrels new goods, Jersey style, good red color. Price 
$3 per barrel.” 
With prices as low as the above quotations indicate, it is difficult to see 
how a cheaper basis for catsup than real tomato stock could be supplied, so 
that pumpkin pulp and other materials alleged to be used for such prepara- 
tions could not be furnished at a much lower price'. 
CREAM OF TARTAR. 
Cream of tartar is used extensively in the household, largely in connec- 
tion with bread making. This substance is in many cases adulterated to a 
la'rge extent. Starch, calcium phosphate, and calcium sulphate (Gypsum) 
being used for this purpose. For an illustration the following analyses will 
show to what extent this substance has been adulterated. 
Alum 62.27 
Silica 1.00 
Lime 76 
Starcn * 14.39 
Cream of tartar 21.58 
Total 100.00 
Or this: 
Cream of tartar None. 
Acid calcium phosphate 25.30 
Calcium sulphate 24.10 
Starch 10.60 
Moisture 40.00 
Total 100.00 
The above results are taken from a report of the Ohio Food Commis- 
sioner of a few years ago. The last report of the same state shows that of 
the twenty-seven samples collected none were found to be adulterated. This 
was not so, however, in the past years, as it was very common to have sam- 
ples adulterated to the extent given above. 
In Massachusetts, 326 samples were collected in 1902, and twenty were 
found to be adulterated. Four samples were tested in connection with this 
investigation and two gave indications of adulterations.
