25,000,000 pounds, most of the fish being prepared at 

 Gloucester. 



Practically all the fish thus prepared goes to the market 

 under the designation of codfish. Of the total quantity of 

 boneless fish, it has been stated that an average of 60 per 

 cent is prepared from cod, 28 per cent from hake, 8 per 

 cent from haddock, and 4 per cent from cusk. The cost 

 of preparing and packing the smaller bricks of boneless 

 fish is about two dollars per 100 pounds. The refuse skins 

 and bones are sold to the companies that manufacture glue 

 and fertilizers. This by-product of the fish amounts to a 

 considerable sum when millions of pounds are used an- 

 nually.
