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 samples adulterated to the extent given as stated above. 



In Massachusetts, of 326 samples collected, twenty were found to be 

 adulterated. Four samples were tested in connection with this invastiga- 

 tion, and two gave indications of adulterations. 



SPICES. 



The spices used in the household are uo doubt adulterated to a greater 

 extent than any other of the products useJ as food. 



Pepper is ariiilterated with ground repper shells, ground olive pits, 

 corn ^eal, and roasted cocoanut shells. 



Allspice is adulterated with wheat .sna exhausted ginger. 



Cassia is adulterated with exhausted ginger and cassia buds. 



Cayenne is adulterated with corn starch and turmeric. 



Cloves are adulterated with allspice, nut shells, sawdust, sand and 

 sweepings. 



Ginger is adulterated with turmeric, buckwheat and powdered char- 

 coal. 



Mace is adulterated with corn starch and wild mace. 



From the results which have been obtained from the investigation of 

 the products sold for food in Iowa and the results from the reports of 

 the food commissions of other states, there is no doubt but there is need 

 of a pure food law in Iowa. Such a law will protect the honest manu- 

 facturer and the consumer. The bulletin and reports will furnish to 

 everyone engaged in supplying food to the citizens of Iowa information 

 which will enable them and the consumers to know what substances are 

 pure and those which are impure. Such a law should be so enacted that 

 it can be of great value to the people when enforced in an intelligent 

 manner.
