The fish may be removed and kept in cold storage for many months 

 at a temperature of 7° to 10°F., that is 25° to 22° below freezing. 



" Too often," as an eminent United States expert^on fish refrigera- 

 tion reported, " freezing fish has meant saving those which were already 

 deteriorating." 'Freezing cannot improve fish, but summer-caught are 

 usually better frozen, unless marketed immediately in a chilled condi- 

 tion, and, if frozen, then deterioration due to heat is prevented. 



The second method, namely, freezing in brine, is very effective. 

 A brine freezer may be of small capacity and carried on the fishing- 

 boat, as has been dobe in Norway, or a freezer of large capacity at some 

 central point convenient for receiving the catches. 



The small brine freezer consists of a 

 woodei tub (see .figure of the apparatus in 

 longitudinal and in cross sections) capable of 

 holding about forty cod of average size. In 

 the centre is fixed a cylindrical vessel of iron, 

 open at the top and covered with wire netting 

 at the bottom, and in the centre a screw pro- 

 peller is placed near the bottom of the tub and 

 provided with a handle at the upper end of a 

 perpendicular axle. The tub is filled two- 

 thirds with a strong brine solution, and 

 crushed ice is placed in the iron cylinder and 

 in the tub. The axle is made to revolve and 

 the brine drawn down into the ice-filled cylin- 

 der, and the water circulating become inten- 

 sely cold in a short -time (15 minutes). It is 

 necessary to put more ice into the cylinder as 

 it melts, to keep the tem,perature down. The 

 fish are suspended in the space around the 

 cylinder, when the temperature reaches 35° F., 

 and should not be placed" too closely so that 

 they do not freeze massed together.f To keep 

 the temperature even, salt and ice must be 

 placed in the inner vessel, as the temperature 

 rises, and the propeller must be worked continuously, if many fish are in 

 the tub. If the tub is only partially filled with fish, it can be stopped for
