Rapids, had identified the species, from specimens taken from one 

 of its most soutlicrly habitats. Horsey Creek, a branch of the Mus- 

 kegon River. 



We early settlers of Crawford County, however, were ignor- 

 ant of the fact, and many long evenings were partly taken up 

 with discussions as to the identity of the fish with which the 

 streams of that county abounded. Supposedly a species of trout, 

 its specific name depended on the particular stream from which 

 it was taken. In that locality it was generally designated Au 

 Sable or Manistee trout. By some, however, it was claimed that 

 this stranger was no trout at all. I^ut more likely a "cisco" or 

 "jack salmon;" while others, wiser in their own conceit, pro- 

 nounced this rara avis a "cross between a sucker and lake her- 

 ring." In 1875 the upper portion of the Au Sable and Manistee 

 rivers retained yet their primal beauty; their stock of grayling was 

 practically intact; a catch of fifty pounds was not an uncommon 

 thing as a result of one day's fishing with a fly rod. By this 

 means the demand from Chicago, Cincinnati and Detroit for 

 grayling was over-supplied, so little was this delicious table 

 fish known. As its fame as a game fish and an epicurean dainty 

 spread, fishermen came from afar, who almost invariably pro- 

 nounced it superior to brook trout in both of these qualities. It 

 is to be hoped that an effort will be made to propagate Thymallus 

 tricolor by methods similar to those employed in the propagation 

 of its congener in Montana. Two questions in regard to tricolor 

 have for some time engaged the attention of fish culturists : First, 

 inquiry as to the cause for the rapid depopulation of grayling 

 streams; second, why have attempts at artificial or protected 

 propagation of the s])ecies been economic failures? ( )wing to the 

 gregarious and fearless nature of tricolor. I believe that the same 

 amount of fishing on a grayling and trout stream of similar cliar- 

 acter would make a greater impression on the stock in the gray- 

 ling stream than in the trout stream. The real cause for the 

 practical extermination of Michigan grayling, however, has been 

 logging operations.
