114 Bass, Pike, and Pe-rch 



We were perfectly sure that it was his, as he had

 retaken three times, twice by my friend and once 

 by myself. The lips of the perch being then 

 quite ragged from the frequent hooking, it was 

 humanely killed and deposited in the basket. 



From my experience with both wild and domes-

 and the gelatinous character of the spinal marrow
