Calcium Cyanamid. Seven samples, representing five 

 analyses, were inspected. The average total nitrogen has been 18.03 

 per cent. The average ton price has been $73.28, making the pound 

 cost of nitrogen 20.3 cents. The samples were found to be well up 

 to the minimum guarantee. 



Castor Pomace. Twelve samples were analyzed, representing 

 four brands. The cash price per ton of this material has been $31.43. 

 The average per cent of nitrogen found was 4.84, making the pound 

 cost of nitrogen 32.5 cents. All of the samples were found well up to 

 the guarantee. 



Cottonseed Meal. Sixty-three samples of cottonseed meal 

 have been analyzed. The average cost has been $43.10 per ton. 

 They have shown an average of 6.34 per cent nitrogen, making the 

 pound cost of this element 34 cents. This is not taking into considera- 

 tion the value of the phosphoric acid and potash, but assuming that 

 the meal was bought for its nitrogen content alone. It is safe to say 

 that the value of the potash and phosphoric acid in average cotton- 

 seed meal is around $7.00 to $7.50 per ton at present prices. Fourteen 

 samples, or fourteen carloads, have shown commercial shortages, the 

 value of potash and phosphoric acid not having been taken into 

 consideration. The shortages are as follows: 



Humphreys-Godwin Co. Forfat Brand Cottonseed Meal, No. 57. 

 Nitrogen found 5.96%, guaranteed 6.17%. Five other carloads were 

 found well up to the guarantee. 



Union Seed & Fertilizer Co. American Red Tag Cottonseed 

 Meal, Nos. 12, 27, 53, 62, 75, 76, 106, 107, 108, 229, 392, 492, 660. 

 Average nitrogen found 6.02%, guaranteed 6.17%. Eighteen other 

 carloads did not show a commercial shortage. 



It might be said in this connection that nearly all of the cotton- 

 seed meal bought for fertilizing purposes is sold on a basis price, 

 rebates being allowed for nitrogen deficiencies, and over-runs paid 

 for on the same basis, a unit price for nitrogen or ammonia being 

 agreed upon. The writer does not know of any cases where proper 

 rebates have not been allowed. 



Nitrate of Soda. Twenty-three samples have been examined, 

 necessitating 15 analyses. No deficiencies were found. The average 

 nitrogen content has been 15.64 per cent. The average cost of nitrate 

 of soda has been $78.29, making the pound of nitrogen cost 25 cents.
