94 EXPEEIMENTS ON THE PRODUCTION OP AETIFIOIAL BAIT. 



sprinkled over them ; this jar was then surrounded with a mixture of 

 ice and salt, so that the temperature did not rise above 28° F. At 

 the end of about a fortnight the jar was opened, and the water which 

 had accumulated at the bottom poured out ; the jar was again closed 

 and kept for three weeks in ice ; the squid was then of a pink colour, 

 but was quite fresh, and fifty hooks baited with it caught four 

 conger, while fifty with natural bait caught only one conger and two 

 pollack. This shows conclusively that squid can be kept for a 

 considerable time in a frozen condition, and, if this process could be 

 carried out on a larger scale, with refrigerating apparatus, the 

 expense need not be very great. I intend to try if pilchards can be 

 preserved in a similar way. This has been attempted, but the 

 temperature was allowed to rise too high, and decomposition 

 occurred.
