current in deeper water, he appeared to live in 

 harmony with these fish. The Montana grayling 

 and the cut-throat do not war upon each other; 

 the red-spotted trout of Michigan and the gray- 

 ling are antagonistic, and the latter fish is gradu- 

 ally becoming extinct, the most probable cause 

 being that the grayling spawn in the spring, and 

 the trout, spawning in the fall and having recu- 

 perated from its debilitating effects, and huge in 

 appetite after a winter's hibernation, devastate the 

 spawning beds of the grayling; for no lure or food 

 is so attractive to the salmon family as their own 

 ova. On the other hand, the grayling of England 

 {Thymallus vulgaris), when living in the same 

 water with the brown or German trout, a robust 

 fish growing to a large size, gets the upper hand, 

 and the trout decrease in numbers and somewhat 

 in quality. In Montana waters the river whitefish, 

 as well as the trout and grayling, apparently live 

 in amity, and all thrive apace. 



Wherever the cut-throat lives in the lower 

 waters of streams or coastwise ponds or lakes, 

 with access to salt water, he may be found also in 

 the bays and tributaries, and doubtless ranges sea- 

 ward as far as the salmon. Under this condition, 

 a silvery coating is assumed and the black spots,
