The foregoing table indicates the following variations from prices 

 a year ago. Sulfate of ammonia has increased 1 per cent, and the 

 other ammoniates have decreased as follows: Ground blood, 5 per 

 cent.; cencentrated tankage, 4 per cent.; crushed tankage, lOi and 15, 

 and 10 and 10, 8^ per cent., and crushed tankage sold per unit of am- 

 monia 1 per cent. 



The Emjinetrhuj and Mining Journal of New York City, gives 

 quotations of sulfate of ammonia and nitrate of soda for January, 

 1902, 2.8375 and 1.97 per cwt., respectively, as compared with 2.76 

 and 1.85 for the same month last year. All these figures are con- 

 firmatory of those already quoted showing a slight advance in the 

 wholesale price of ammonium sulfate, a marked advance in the case 

 of nitrate of soda, a shrinkage in the value of blood and tankage 

 and quite a marked decrease in the case of bone. 



Of the animal raw materials furnishing phosphoric acid, refuse 

 bone-black only has fallen off somewhat in price. The following 

 summary from the Engineering and Mining Journal shows the prices 

 of rock phosphate. Lower freight rates helped to increase the ex- 

 port trade about 17 per cent., 750,000 tons being shipped as against 

 f)19,996 tons in 1900. 



Florida Phosphate: The largest business was done in high grade 

 rock, the exports amounting to 428,000 tons or about 80,000 tons 

 more than last year. The chief demand for pebble phosphate was 

 for home consumption, the exports, however, being larger than last 

 year. Prices during the year were: For high grade rock ((77-80) per 

 cent.) f. o. b. Fernandina, |7.25 in January, $6.75 from February to
