 ated than any other food. The watering and skimming 

 of milk are the chief ways of adulteration, but some- 

 times a substance is added to give it a better color. 

 This makes the milk less nutritious, and it is more 

 likely to contain disease germs. Milk is such an impor-

 butterine or oleomargarine. It cannot be maintained 

 that butterine is unhealthful, provided it is made of 

 pure, clean materials, but it is very often sold for 

 good, pure butter. Many of the states have laws re- 

 quiring all butterine to be properly labeled, and some 

 require a conspicuous sign stating the fact that butter- 

 ine is there sold or used. Fats, oils, and grease are 

 sometimes used in the manufacture of cheese, but any 

 such inferior and adulterated product put on the mar-
