In this case also, while the range of composition is not exception- 

 ally wide, the average percentages of the more valuable materials 

 are distinctly below those exhibited in States subject to a cattle- 

 food control. 



In nine samples whose protein was less than 14.75 per cent., de- 

 terminations of fiber and ash were made with results ranging from 

 7.03 to 1.08 per cent, for fiber, and 4.8G to 3.90 per cent, for a»h. 

 Twenty-three samples analyzed in Connecticut iu 1899, showed fiber, 

 10.31 to 1.05 per cent., and ash, 5.52 to 2.SG per cent., and fourteen 

 samples analyzed in New York, the same year, showed fiber, 10.35 to 

 2.17 per cent., and ash, 5.10 to 2.52 per cent. Clearly, the low protein 

 in the Pennsylvania samples is not attributable to excessive quanti- 

 ties of these two elements introduced by conspicuous additions of 

 foreign matters. These analyses would not show the addition to a 

 pure middlings of large quantities of the fluffy dust from the dust 

 room, in which the hairs from the tip of the grain are deposited as 

 a result of the modern milling processes. 



The name attached to the brand gives no certain indication of 

 feeding value. This is well exhibited by the range of protein content 

 found in those specimens to which some particular grade name was 

 given. 



"Pure," "white," "finished," 17.13 to 12.04 per cent. 



"No. 2 white,' 17.81 to 14.88 per cent. 



"Ked," 18.50 to 14.44 per cent. 



"Brown," 18.38 to 14.81 per cent. 



The "white" middlings contain, of course, more starch than the 

 "brown" middlings, bran being more abundant in the latter. 



Microscopic examination with a low-power lens discovers no con- 

 spicuous foreign material except in case of No. 75. which is rendered 

 quite impure by the presence of numerous weed seeds.
