EXPLANATION AND DISCUSSION OF THE RESULTS. 



The Interstate Cottonseed Crushers' Association at 



Cottonseed its May meeting 1906, graded cottonseed meal as 



and follows : 



Linseed Meals. Section 2. Choice vieal must be finely ground, 



Pages 7-10. perfectly sound and sweet in odor, free from excess 



of lint and hulls, and by analysis must contain at 



least 8 per cent of ammonia (41-15 per cent protein.) 



Section 3. Extra prime meal must be finely ground, of sweet 

 odor, reasonably bright in color, yellow, not brown or reddish, and 

 by analysis must contain at least 7.5 per cent of ammonia (38.50 per 

 cent protein.) 



Section 4. Prime meal must be finely ground, of sweet odor, 

 reasonably bright in color, and by analysis must contain at least 7 

 per cent of ammonia (36 per cent protein). 



Section 5. Off meal : Any cottonseed meal which is distinctly 

 deficient in any of the requirements of prime quality, either in color, 

 odor, texture or analysis, or all, shall be deemed OfT Meal and should 

 be sold by sample. 



The Station has adopted substantially the above grading. It des- 

 ignates as high grade meal (choice) that testing 41 per cent or more 

 protein ; as medium grades (extra prime and prime) those testing 

 from 36 to 41 per cent protein ; as low grade (off) all meals testing 

 below 36 per cent protein. It likewise adopts the same requirements 

 as to mechanical condition, taste, color and odor as the Association. 



There have been collected, examined and reported 23 samples of 

 high grade and 29 samples of medium grade meals. Most of them 

 met their protein guarantees and were of good color and taste. 



Two samples of Chapin's Green Diamond brand were guaranteed 

 41 per cent protein and 9 per cent fat, and tested only 37.08 and 

 37.34 per cent protein and 6.58 and 6.35 per cent fat. One sample 

 of Cox's Magnolia brand carried a 43 per cent guarantee and tested 

 39.14 percent protein.* A lot put out by J. E. Soper & Co. called 

 for 41 per cent protein and 9 per cent fat, and showed 36.46 per cent 

 protein and 6.06 per cent fat. 



* C. M. Cox Co. claim that this does not truly represent their product.
