 CHEMICALS AND RAW PRODUCTS 



Summary of Results of the Inspection of Chemicals and Raw Products 



* The average commercial valuation of the phosphoric acid and potash in a ton of cottonseed meal 

 according to 1924 fertilizer valuations, is about S3. 91 ; in rapeseed meal about .12.54; and in castor pomace 

 about $2.50. These values were not included in computing commercial valuations nor in calculating the 

 cost of nitrogen. 



2 .\llowing 19.1 cents as the value of a pound of nitrogen, the potash costs 6 cents per pound. 



3 Average tankage finer than Ho inch diameter, 46.30 per cent; coarser than }4o inch, 53.70 per cent. 



* Average bone finer than Ho inch diameter, 65.24 per cent; coarser than }io inch, 34.76 per cent. 



5 Average of the ten analyses showed 5.44 per cent of acid soluble potash, 14.68 per cent of water, and 

 14.75 per cent of insoluble earthy matter. 



* These figures are based on the potash and phosphoric acid and do not include the commercial value 

 of the lime and magnesia, which in a ton of average wood ashes would amount to $2.50 to $3.50. 



Nitrogen Compounds. 



The tables immediately following give the analyses of chemicals and crude 

 stock materials valued chiefly for their nitrogen. When more than one analy- 

 sis was made of the same brand, an average has been given. Brands showing 

 a commercial shortage of $1.00 or over per ton are included in a table by them- 

 selves and the deficiencies are represented by boldface type.
