INTERPRETATION 0^ THE LAW. 



While there have been no court decisions in Maine, the execu- 

 tive officer will, until he is better informed, be guided by the 

 following statements in the enforcement of the law concerning 

 vinegar. 



The standards above named, adopted under section 5 of the 

 law, are part of the pure food law. 



The word vinegar, as defined in section i of the standards, 

 lanless otherwise qualified, always means cider vinegar. To sell 

 anything else than cider vinegar when vinegar is asked for, is 

 prohibited by the law. 



No vinegar whether cider or otherwise, carrying less than 

 4 per cent of acetic acid, can legally be sold unless the per cent 

 of acid is stated on the package.
