The hooks were baited with these artificial baits by an experienced 

 fisherman, but in all cases the result was the same. Not a single fish 

 was caught, either with the uuflavoured or with the flavoured baits, and 

 even the tin foil was unsuccessful, although one might naturally have 

 expected that, when the lines were being set or lifted, the hooks, baited 

 with tin foil, when in motion might have caught some fish. Not only did 

 the long line hooks with tin foil not catch any fish, but an artificial troll 

 of 120 hooks, half of which were baited with sponge and half with tin 

 foil, did not take a single fish, although a similar troll baited with 

 bullock's liver and with mussels was very successful. 



So far as artificial lures are concerned the results of the experiments 

 are entirely negative, but they reveal certain interesting facts in reference 

 to the preference by certain fish for certain baits.
