310 THE LABEADOR PENINSULA. CHAP. xvin. 



parts of the recent offal yield on an average twenty-two 

 parts of the powder, besides from two to two and a half 

 parts of oil. The manufactory of Concarneau employs six 

 men and ten boys, and is able to work up daily eighteen or 

 twenty tons of fish, and produce from four to five tons of 

 the powdered manure. 



' This manure contains, according to an average of seve- 

 ral analyses, 80-0 per cent, of organic matters, and 14'1 

 per cent, of phosphates of lime and magnesia, besides 

 some common salt, a little carbonate of lime, small 

 portions of sulphate and carbonate of ammonia, and only 

 I'O per cent, of water. The nitrogen of this manure, 

 which is almost wholly in the form of organic matters, 

 corresponds to 14-5 per cent, of ammonia, and we may 

 estimate the phosphoric acid, which is here present in an 

 insoluble form, at 7-0 per cent. If we calculate the value 

 of this manure according to the rules laid down on page 

 314, we shall have as follows for 100 pounds : 



Ammonia 14 J pounds, at 14 cents . . $2-03 

 Phosphoric acid 7 pounds, at 4^ cents . 0-31J 



$2-34^ 



' This is equal to $47 the ton of 2,000 pounds ; the 

 manufactured product of Concarneau, however, according 

 to Pay en, is sold in the nearest shipping ports at 20 francs 

 the 100 kilogrammes (equal to 220 pounds), which, 

 counting the franc at $0'20, is equivalent only to $1'81 

 the 100 pounds, or a little over $37 the ton. This how- 

 ever was in 1854, since which time the price of manures 

 has probably increased. 



' M. Demolon, in company with his brother, has also, 

 according to Pay en, erected a large establishment for the
