354 AMERICAN GAME FISHES. 



tat of the Montana and Michigan Graylings. The latter 

 lives and thrives only in rivers, spring-fed, with sandy bot- 

 toms, and of a temperature seldom exceeding fifty-two 

 degrees. Our recollection of the Manistee in Michigan, upon 

 which we spent several days among the Grayling two years 

 ago, is that we did not see even a pebble upon the bottom, 

 except, here and there, a small cluster of stones not much 

 larger than hen-eggs, which were exposed on the rapids by 

 the rapid rush of the stream, and these stony rifts were of 

 small dimensions, and often a mile or two distant from each 

 other. The rest of the stream consisted of shallow, sandy 

 reaches and pools, at the bottom of which the sand was 

 mottled with patches of white and yellow with dark blotches 

 here and there, formed by a deposit of drift. In the Gallatin 

 the conditions are reversed. The temperature often reaches 

 sixty degrees, and the bed of the river is for the most part 

 rocky, at least, covered with stones, the smallest of which 

 may be represented by the cobble-stones of street pavements. 

 In truth, the pool above referred to, in which I caught most 

 of my Grayling, was rough-strewn with rocks, many of 

 which sized up to that of a bushel measure; a sandy reach 

 was not seen along the two miles of the stream fished by our 

 party. 



"Again It is an established fact that the Michigan Gray- 

 ling cannot live and increase in any stream in which trout or 

 other fish have established themselves. They seem to 

 diminish very rapidly under such conditions, and, strange to 

 say, the reverse is the fact in English waters, where Thymal- 

 lus holds its own against the brown Trout. In the Gallatin, 

 the Trout, the Grayling and the Whitefish live in harmonious 

 brotherhood. On one occasion, using three flies as an 

 experiment, I caught one of each of these three fish, at the 

 same cast, showing that they feed and range together. 



"The ordinary Trout-flies used in the East will, under fa- 

 vorable conditions, lure the Grayling, the Trout and the White-
