pursed to prevent the fish from escaping. Its capacity is about 20 metric tons. 

 One advantage claimed for the gear is its ability to fish at much greater depths' 

 than ordinary nets. 



ELECTRICALLY- LIGHTED 

 LURE OR J1G. 



ELECmiCALLY-LIgiTED JIG ; An electrically- , 

 lighted lure or jig for line fishing, which can be 

 connected to a battery or a fishing craft's lighting 

 system, has been invented by a Norwegian skipper, 

 Andreas Flesland of Flesland in Fana, Norway. The 

 inventor has filed for a patent. 



A two-phase cable insulated with plastic is used 

 as a line. The type used in tests had a breaking 

 strength of I76 pounds, but further tests are under 

 way with a cable of smaller dimensions^ 



Ths lure or jig consists of a cylinder pointed 

 at each end (see sketch). The ends are of metal 

 Tuftiile the central portion is a special type of pres- 

 sure-resistant glass cylinder within which an elec- 

 tric lamp is placed. Die strength of the lamp 

 depends upon the battery or power source , for ex- 

 ample 10 amperes and 24 volts or 10 amperes and 12 

 volts. The lamp is connected to the cable and the 

 latter is fastened to the eye in the lure or jig with 

 a turn so that there is no direct strain on the lamp 

 connection. Watertight seals of rubber are used be- 

 tween the glass and the metal. A. firmly fixed triple 

 hook of slightly greater dimensions than in the 

 Illustration is used. It is reported the lure has 

 had a good reception by fishermen.

FISH CANNERS ACCOBDED PRIORITY FOR TIN PLAIE ; 

 The shortage of tin plate has been a cause for con- 

 cern to Norwegian canners, according to a January 29 

 American consular dispatch from Oslo. The Norwegian 

 Government had forbidden the use of tin plate, effec- 

 tive on January 1, in certain food-preserving opera- 

 tions, but accorded priority to canners of fish and 

 other export products,

EXPERIMENTAL STORA(a: SILOS FOR HSHRING ; Methods for preserving herring for 

 later reduction into meal and oil are being tested by the Norwegians, a January 23 

 American consular dispatch from Bergen reports. 



The new experimental storage plant at Trolleb^S (close to Maalfiy) is now ready 

 for the storage of herring. Two of the three contemplated silo tanks for storage 

 of herring are completed. One has a capacity of 180 metric tons and the other 

 720 tons. It is expected that the third tank will be finished during the course 

 of the season. In addition to the tanks, a bin with a capacity of approximately 

 720 tons has also been built. Engineer Sola, an employee of the Chemical and Tech- 

 nical Experimental Institute of the Norwegian Directorate of Fisheries, has been
