of lime, from eight to 12 per cent, of silica, and from two to 

 four per cent, of oxids of iron and alumina. 



Small deposits of phosphates occur in other parts of the United 

 States ; namely, in North Carolina, in Pennsylvania, in Arkansas, 

 and in Alabama. Lately deposits have also been found in Wyo- 

 ming, in the county of Uinta, near the village of Cokeville, which 

 are made up of grayish black phosphates in the form of heavy 

 and very durable rocks. These deposits are found in the upper 

 carboniferous rocks of the central Cordilleran region in a series 

 of oolitic beds. 



Considerable quantities of phosphates are also produced in 

 Canada. The smallness of the deposits and the difficulties of 

 quarrying, however, have kept the Canada production down to a 

 small amount, the production not exceeding 30,000 tons per year. 

 It is estimated that only about 850,000 tons of phosphate rock are 

 exported to Europe from the United States, principally from 

 Florida and Tennessee, Florida leading with about 85 per cent, 

 of the total exportations. 



45. Magnitude of Product. In 1904 the production of phos- 

 phates in the United States, principally in Florida, Tennessee 

 and South Carolina, amounted to approximately 1,782,503 long 

 tons, valued at $5,703,582. This is an increase compared to 

 1903 of 212,275 tons in quantity, and $709,670 in value. 

 Exports in 1904, chiefly to Germany, France, Italy and 

 Great Britain, totaled about 880,000 tons as against 785,259 

 tons in 1903, showing an increase of 94,741 tons, or 12 

 per cent. The ocean freight was $2.64 to $3.72, equivalent to 

 from one-third to one-half of the c. i. f. prices paid for the phos- 

 phates, which were $9.84 to $12.09 f r Florida high-grade rock; 

 $6.39 to $8.40 for land pebble ; $9.54 to $i 1.40 for Tennessee rock ; 

 $5.61 to $6.88 for South Carolina rock. In competition with the 

 American phosphates were exports of 775,000 tons from Africa, 

 paying an ocean freight of $1.44 to $2.22, and selling in Europe 

 at $6 to $7.60 for Algerian, and $5.75 to $6.60 for Tunis rock. 

 There were also sent to Europe in 1904 some 125,000 tons high- 

 grade phosphate from the Christmas and Ocean islands, paying a 

 freight of about $6.48, and marketed at $11.75 to $!4-45 P er ton,
