358 INTRODUCTORY REMARKS. 



ing the more interesting sea-fish of the Southern States ; but having 

 waited as long as it was possible, for a number of specimens of which 

 I had a promise from a friend in Charleston, South Carolina, I am 

 very reluctantly compelled to go to press without that advantage, and 

 am precluded from doing much more than naming what I learn to 

 be the best and gamest of the southern species. 



In this Supplement, I shall adhere to the plan adopted in the Vol- 

 ume, of dividing it into two parts, one treating of the structure, habits, 

 and classification of the fishes ; the other of the implements, the ma- 

 terials, and the art of angling. 



The Salmon family will claim as of the Volume itself, so of the 

 Supplement also the larger portion. Of this interesting group, the 

 proper Salmons, I have herein inserted descriptions of six new species 

 peculiar to the Columbia and other rivers of the Pacific coast, now 

 growing into so great importance ; and of the sub-genus Coregonus, of 

 the same group, I have two new varieties from the north-western lakes. 

 Concerning the several varieties of Lake Trout, I have cause materi- 

 ally to modify opinions expressed heretofore ; and have succeeded in 

 collecting much new information as to their habits, quality, instincts, 

 and the mode of capturing them. 



To the various friends who have assisted me with advice, informa- 

 tion, and friendly criticism, I take this opportunity of again express- 

 ing my gratitude, and of putting it on record how much is due to them 

 of the increased value of this edition.
