the small trout of other species In the same pond. I saw a mounted 



specimen that was taken in a tributary of the Yellowstone near Liv- 

 ingston that was said to weigh ten pounds when captured, which was 

 probably correct, as it was thirty inches long. 



THE BROOK TROUT. (Salvelinus fontinalis), 

 The eastern brook trout has both crimson and yellowish spots, with 

 dark marblings on the back. At spawning time the males have the 

 lower part of the body bright scarlet, of a more intense color than the 

 other species mentioned. The paired fins are bordered with both 

 black and white lines. It is the most beautiful of all tho trouts. Ajs a 

 game- and food-fish it ranks high, but is excelled in game qualities by 

 both the rainbov,^ and steelhead, which, however, is no disparagement. 

 It has been introduced of late years from Bozeman Station to many 

 ponds and streams thoughout the state, where it has uniformly done well. 

 One was taken on the fly from the pond of Mr. Hoffman, previously refer- 

 red to, that weighed three and one-han pounds at three years of age. 

 I also know of two being taken from a tributary of the Madison, near 

 Ennis, where they were planted by the U. S. Bureau of Fisheries, that 

 weighed respectively one and one-half and two pounds at one and a half 

 years of age. Two of the same hatching were taken the same autumn 

 of like weights in Bridger Creek. The low temperature of the east 

 Montana waters seems to be eminently suitable for the brook trout. 



The DOLLY VARDEN TROUT. (Salvelinus parkei). 

 The Dolly Varden, or bull trout, sometimes erroneously called "salmon- 

 trout," is the only red-spotted trout native to western waters. It be- 

 longs to the same genus as the eastern brook trout, but grows much 

 larger. It is found in Montana only on the Pacific slope in both lakes 

 and streams, growing to twelve or fifteen pounds under favorable condi- 

 tions. In the streams it is a gamer fish than in lakes, though the larger 

 fish are rather lazy and logy. Compared with its eastern relative it 

 is hardly so vigorous on the rod, when of similar weight, and not quite so 

 good for the table. 



THE LAKE TROUT. (Cristivomer namaycush . 



The lake trout is closely allied to the eastern brook trout, though it 

 grows very much larger, and is confined to very deep lakes. In the 

 Great Lakes it often reaches forty pounds in weight, and is stictly a com- 

 mercial fish, though it is often taken by deep trolling with the minnow. 

 It never rises to the artificial fly. I have taken it on the trolling spoon 

 In the Straits of Mackinaw, and in the bay at Marquette on Lake Super- 

 ior. It is one of the best fresh-water food-fishes. Its spots are large 

 and of a grayish coloration. 



In the books it has never been credited to Montana, though it exists 

 in Elk Lake at the head of the Jefferson, but nowhere else so far as I am 

 aware west of of Lake Michigan, which is likewise true of the grayling. 

 It is credited in the books to Henrys Lake, Idaho, but this is a mistake 

 which I corrected a year or two ago. Many years ago it was taken at 

 Elk Lake by Mr. Sawtelle and Mr. Sherwood, of Henrys Lake, and not 

 knowing what it was they forwarded specimens to the Smithsonian Insti-
