establishments, requires no attention on the part of the United States. 

 A second eastern species, of great beauty, the blue-back, [Salmo oquassa, 

 Girard,) is found in the lakes at the headwaters of the Androscoggin, 

 Rangeley, Oquassoc, &c., where it inhabits their depths for the greater 

 part of the year, only coming to notice for a few weeks in the autumn, 

 when it enters the tributary streams or outlets to spawn. ]S"o proposition 

 has yet been made to multiply this species artificially. 



In this connection it may be remarked that, in the same lakes, the 

 common brook-trout {Salmo fontinalis) occur of enormous size, even up 

 to ten pounds, and that Mr. George Shepard Page, and his associates of 

 the Oquassoc Angling Company, are about establishing a hatching-house 

 for the purpose of securing eggs of this variety, known as the Rangeley. 



There are many species of brook and pond trout in the Rocky Mount- 

 ain and Pacific region of the United States, as well as in British Xorth 

 America; none of which, so far, have attracted the attention of fish- 

 culturists on account of special merit. 



10. — The Salhling, (Salmo salveUnus.) 



Another European fish that might be introduced to advantage is the 

 char, or Salmo salveUnus. This is a species that lives, more or less, in 

 the larger lakes, running up into tributary streams to spawn, and in 

 this connection would serve an excellent purpose for stockiug interior 

 waters that have now no specially desirable inmates. 



11. — The grayling, {Thymallus tricolor.) 



A species of the salmon family found in restricted areas of the United 

 States, has lately attracted much attention among fish-culturists and 

 sportsmen. It seems to be prolific and numerous in favorable waters; 

 is excellent as food, and what, to many, are more admirable quali- 

 ties, will take the fly and make a spirited contest with the angler before 

 he can land him on the shore or in his boat. It has also a most beauti- 

 ful combination of colors on the body as well as on the very large 

 dorsal fin that is a peculiar character in this genus. 



The grayling has lately been brought extensively to notice as occur- 

 ring in the waters of Michigan, and even in that State seems to be con- 

 fined to certain spring-fed rivers in the lower peninsula. It is also 

 found in the headwaters of the Missouri in the region adjacent to the 

 valley of the Yellowstone. Whether it is different from the grayling 

 found in certain rivers of Alaska, is a question not yet positively de- 

 cided, but its separation as a species from the English and European 

 Thymallus vulgaris Nilss. is marked and decided. 



It has been successfully transported from Michigan to Tn'cw York 

 State by Fred. Mather and Seth Green, as also to Southern Michigan, 

 for the purpose of introduction into trout-streams. Seth Green has 

 succeeded in hatching the eggs, and has found them well adapted to 

 the artificial processes.
