the Lexington Grain Co. tested but 19.62 per cent protein; two 

 samples of Bay State averaged only 20.33 P^^ cent protein ; one 

 sample of New England showed 20.40 per cent protein. These low 

 testing goods were guaranteed to contain 22 per cent protein,' and 

 retailed for fully as much as many goods testing 24 or more per cent. 

 They were not adulterated, but were the result of corn low in protein,
