milk production, and at prices usually prevailing is almost always an 

 economical concentrate. A first grade gluten feed ought to contain 

 25 per cent protein and 3 per cent fat. 



One lot put out by the Buffalo Cereal Co. was guaranteed 28 per 

 cent protein, and tested 25.45 per cent. Two lots of the Flint Mill 

 Co.'s product were guaranteed 27 per cent protein and analyzed 

 24. 88 per cent. Eleven samples of Buffalo averaged 24.82, and 

 carried a 25 per cent guarantee. 



Three samples of Globe carried a 26 per cent protein guarantee 

 and tested 26.59 P^^ cent. This brand almost always meets its 

 guarantee. 



The Tiger brand (four samples) averaged 25.61 per cent protein 

 and carried a 25 per cent guarantee. Warner's gluten tested only 

 slightly below its 25 per cent protein guarantee. 



Douglas & Co.'s gluten feed was guaranteed 26.50 per cent pro- 

 tein and the six samples averaged only 17.65 per cent. This is not 

 a first grade product, and a guarantee so far above its actual test is 

 entirely unwarranted.* The material does not appear to be adulter- 

 ated, but contains an undue proportion of starch. Properly guar- 

 anteed it would be a perfectly legitimate article of trade. One 

 sample of Golden Rod, put out by the Michigan Starch Co., was 

 guaranteed 27 per cent and tested 19.88 per cent. 



Bay State gluten feed, put out by J. E. Soper & Co., only one sam- 

 ple of which was collected, tested 15.88 per cent protein, and was 

 guaranteed 26 per cent. Soper & Co. state that this in no way 

 represents their product. Further comment is therefore withheld for 

 the present.
