These quotations confirm the previous figures showing a marked 

 increase in the price of nitrate of soda and a slight advance in case 

 of sulphate of ammonia. 



The American consumption of nitrate of soda in 1904, according 

 to the Engineering and Mining Journal was the largest on record, 

 275,000 long tons, notwithstanding the high prices- of $45.26 to $53.20 

 per ton. 



The following summary from the "Engineering and Mining Jour- 

 nal" outlines the prices of rock phosphates: 



Enormous consumption of phosphoric acid, both in this country 

 and Europe, initiated active mining and improved prices. In 1904, 

 the production of phosphates in the United States principally in 

 Florida, South Carolina and Tennessee, amounted to approximately 

 1,782,503 long tons, valued at $5,703,582. 



The domestic trade, which takes little over one-half the produc- 

 tion, showed some advance in 1904, and prices ranged from $6.50 to 

 $7.50 per ton for high grade rock f. o. b. Florida ports; $3.75 to $4.00 

 for Florida land pebble; $4.00 to $4.25 for Tennessee export rock 

 f. o. b. Mt. Pleasant and $2.95 to $4.00 for the various domestic 

 grades; $2.75 to $3.50 for South Carolina rock f. o. b. Ashley River. 



Quotations for January and February of this year were: for 

 Florida land rock, $7.25 @ $7.50; Florida land pebble, $3.75 @ $4.00; 

 Tennessee 78-80 per cent., $4.00 @ $4.25; Tennessee 7s per cent., 

 $3.75 @ $4.00; Tennessee 75 per cent., $3.25 @ $3.50; South Carolina 

 land rock, $3.25 @ $3.50 and South Carolina river rock, $3.00 

 @ $3.25.
