The Inter-State Cottonseed Crushers' Association 

 Grading Cot- at its annual meeting held at Memphis, May 19-20- 

 tonseed Meal. 21, 1909, established the following rules for grading 



cottonseed meal : 



Rule 12, Section i. Choice cottonseed meal must be finely ground, 

 perfectly sound and sweet in odor, yellow, free from excess of lint, 

 and by analysis must contain at least 8 per cent, of ammonia (6.56 

 per cent, nitrogen) or 49 per cent, of combined protein and fat.* 



Section 2. Prime cottonseed meal must be finely ground, of sweet 

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

 from excess of lint and by analysis must contain at least 7.50 per cent, 

 of ammonia (6.18 per cent, nitrogen) or 46 per cent, of combined 

 protein and fat.* 



Section 3. Good cottonseed meal must be finely ground, of sweet 

 odor, reasonably bright in color, and by analysis must contain at 

 least 7 per cent, of ammonia (5.75 per cent, nitrogen) or 43 per cent, 

 of combined protein and fat.* 



It is quite natural, as has already been pointed out 

 Quality that cottonseed meal should vary in chemical com- 

 Deteriorated. position as well as in appearance, depending upon 

 the season, method of handling, and locality in 

 which it is grown It is evident that the meal sent into Massachu- 

 setts of late years has decreased somewhat in quality or has come 

 from different shipping points as the following analyses made at this 

 laboratory will show : 



HIGH AND MEDIUM GRADES. 



*The Station endorses the ammonia or nitrogen but not tho combined protein and fat 

 guarantee as a basis for settlement. A lot of meal may contain the requisite 49, 46 or 43 per 

 cent of combined protein and fat, but through faulty extraction or for some other reason, 

 not the necessary nitrogen, ammonia or protein equivalent. Thus, if a 49 per cent, com- 

 bined guarantee should contain 11 per cent, of fat, it would contain only ;jS per cent, of pro- 

 tein instead of the necessary 41 per cent. Inasmuch as cottonseed meal is purchased pri- 

 marily for its nitrogen or protein, it is believed to be fairer to adhere to the nitrogen or 

 ammonia content of the meal as a basis of settlement. In Massachusetts it is illegal to 

 present a combined protein and fat guarantee.
