The fresh waste, skins, bones, etc., of the fish are 

 worked up for glue, the residue being manufactured 

 into fertilizer. The best glue is obtained from the 

 skins. The cod and cusk skins are superior in this to 

 the skins of hake and haddock. 



The oil is extracted from the livers. That from 

 fresh livers is refined and used for medicinal purposes, 

 while that from old livers is used for tanning chamois 

 leather. The value of this oil is considerable, as much 

 as 150 being received by a boat in one trip for the oil 

 alone. 



In 1914, Newfoundland exported 60,000 tons of cod 

 meat, worth /1, 600,000. The chief market is the 

 Mediterranean.
