§ 23. Regulations in regard to butter and cheese factories. — No 

 person shall sell, supply or bring to be manufactured to any but- 

 ter or cheese factory any milk diluted with water, or any un- 

 clean, impure, unhealthy, adulterated or unwholesome milk, or 

 milk from which any of the cream has been taken, except pure 

 skim milk to skim-cheese factories. No person shall sell, supply 

 or bring to be manufactured to any butter or cheese factory any 

 milk from which there has been kept back any part of the milk 

 commonly known as strippings, or any milk that is sour, except 

 pure skim milk to skim-cheese factories. The owner or pro- 

 prietor or the persons having charge of any butter or cheese fac- 

 tory, not buying all the milk used by him, shall not use for his 

 own benefit, or allow any of his employes or any other person 

 to use for his own benefit, any milk, cream, butter or cheese or 

 any other product thereof, brought to such factory, without the

 Every butter or cheese manufacturer not buying all the milk he 

 uses, shall keep a correct account of all the milk daily received, 

 of the number of packages of butter and cheese made each day, 

 and the number of packages and aggregate weight of cheese and 

 butter disposed of each day; which account shall be open to in- 

 spection to any person who delivers milk to such factory. When- 

 ever manufacturers of butter or cheese purchase milk upon the 

 basis of the amount of fat contained therein and use for ascer- 

 taining the amount of such fat what is known as the Babcock 

 test, the bottles used in such test shall before use be examined 

 by the director of the Geneva Experimental Station. If such 

 bottles are found to be properly constructed and graded so as 

 to accurately show the amount of fat contained in milk, each of 

 them shall be legibly and indelibly marked " S. B." No bottle 

 shall be so marked except as herein provided nor shall be used 

 in any such test by such manufacturers, unless so examined and 

 marked. The acid used in making such test by such manufac-

 chemists employed by the commissioner of agriculture and if 

 found not to be of sufficient strength the use of such acid shall
