16 BULLETIN 2, U. S. DEPARTMENT OF AGRICULTURE. 
In 1895, according to the figures compiled by this authority, 
36,496 hogsheads, or about 36,496,000 pounds, of herring were util- 
ized in the canning industry of the Passamaquoddy region. In the 
same year 325 gallons of oil, 31 tons of pomace, and 2,704 barrels of 
waste fish, which were not rendered, were produced. 
In 1905, 33 establishments were engaged in canning sardines. 
Fifty tons of pomace and 1,000 gallons of oil were produced. The 
former fetched $8 per ton and the latter i5 cents per gallon. 1 
Small amounts of the waste produced at the fish-dressing estab- 
lishments of the fishing centers of Massachusetts are utilized by the 
Tenderers of garbage and other city wastes of those sections. These 
amounts are irregular and of small consequence. Undoubtedly they 
could be increased. In the neighborhood of Pensacola, Fla., a plant 
recently has been established for the utilization of the fish scrap and 
waste fish available in that region. It is said on good authority that 
large quantities of mullet, caught on the Florida coast south of 
Tampa, annually are permitted to go to waste for lack of suitable 
market. In previous years skates and other useless fish taken in the 
pound nets at certain places on the New England coast were dried in 
the sun, without rendering, and subsequently were pulverized for 
use as fertilizer. 
REFUSE FROM NEWFOUNDLAND COD. 
The large production of fish waste from the extensive cod industry 
prosecuted on the Newfoundland shores has been the object of much 
speculation in the past. An investigation of the industry has shown 
that about 150,000 tons of refuse is produced there annually. If 
this be regarded as containing 15 per cent solid matter, it would be 
equivalent to over 20,000 tons of dry scrap. This amount of fish 
scrap would be an important addition to the present output from the 
Atlantic fisheries. It has been shown, however, that the scrap is 
produced in small amounts over a long line of shore, that it is thrown 
away as fast as produced, thus requiring to save it a radical change 
in the present methods of work, and that it is produced at a time 
when all the available labor is busily engaged in dressing the cod. 
Its recovery accordingly constitutes a problem which so far has not 
been solved economically and offers scant hope of solution. 
DOGFISH. 
Perhaps the most probable extension of the fish-scrap industry 
through the employment of other fish for that purpose will prove to 
be the utilization of dogfish. This supposition is based on the con- 
sideration of the general hatred for the dogfish entertained by the
