percentage is probably due, partly to poor corn and partly to the 

 imperfect separation of the starch. It is believed that manufacturers 

 place too high a guaranty on gluten feed. It rarely contains 28 per 

 cent of protein, and a guaranty of 25 or possibly 26 per cent would 

 be more nearly correct.

brands offered met the protein guaranty of 33 per 



cent by from 2 to 3 per cent, due perhaps, as was the case with 



gluten feed, to the general inferior condition of the corn. IVie 



manufacturers and jobbers will have to determine 7vhether it will be 



possible in the future to maintain their guaranty. Consumers should 



be sure, before purchasing, that feeds of this character are properly 



guaranteed. 



Four samples of malt sprouts were found, of which three were 

 unguaranteed. Malt sprouts may be considered a satisfactory 

 source of protein for milk production if properly fed. They are 

 highly esteemed by German feeders. They should ahvays be bought 

 on a guaranty of 25 per cent protein, as such material can be easily 

 adulterated. 



The one sample of yeast refuse was unguaranteed, and contained 

 23 per cent protein. It should prove a valuable protein feed, if 

 dried before it becomes too sour.

and fat than those collected a year ago, due in all 



probability to the poorer quality of the 1902 wheat crop. 



Two samples of red dog ^o\xx contained only 14.92 and 15.40 per 

 cent protein and one lot of standard middlings showed but 12.95 per 

 cent protein, much below what is usually found in materials of this 

 character.
