as In the rainbow trout. Its color is also of a lighter hue, with steely 

 reflections. Its scales are somewhat larger than those of the red-throat, 

 but not so large as in the rainbow. 



During the past six years the U. S. Bureau of Fisheries has intro- 

 duced the steelhead in a number of streams and lakes in Montana, which 

 seem to be very suitable for this fine fish. They have been caught 

 during the past year or two as heavy as four pounds, which shows that 

 they have come to stay. The steelhead rises eagerly to the artificial 

 fly, and breaks water repeatedly when hooked; it is very trying to light 

 tackle, and must be handled carefully by the angler. As a food-fish it 

 excels all other trout, as might be surmised. It should grow to eight 

 or ten pounds in lakes of considerable area and depth, and where its 

 food is plentiful. 



THE RAINBOW TROUT. (Salmo irideus). 



The rainbow trout has also been introduced to Montana waters during 

 the past few years by the U. S. Bureau of Fisheries, and seems to be 

 well-adapted to ponds of considerable extent, where water plants and 

 grasses flourish. Such waters seem to be more congenial than the 

 colder mountain streams; and moreover it has a way of disappearing from 

 the smaller streams to seek those of greater depth. It will thrive in 

 warmer water than the other trouts. The rainbow is similar in contour 

 to the red-throat, though somewhat deeper, and with shorter head, smaller 

 mouth, and larger scales. Its distinguishing feature is the broad red 

 band along the lateral line, common to both male and female. It is a 

 handsome fish, with considerably more gameness than the red-throat, 

 but is not so vigorous on the rod as the steelhead of the same size. 

 Owing to its tendency to descend streams it is particularly liable to 

 enter irrigation ditches, in which event its doom is sealed. As a food- 

 fish it is superior to the native red-throat trout. 



THE BROWN TROUT. (Salmo fario). 



The brown trout is the brook trout of Europe, and was introduced to 

 the United States from England and Germany, under the auspices of 

 the U. S. Bureau of Fisheries. Those from Germany, (the eggs), were 

 donated by Von Behr, and his name was unfortuately applied to the fish 

 as "Von Behr trout," also "German trout." As the fish is universally 

 known in Great Britain as the "brown trout", that name should be ad- 

 hered to in this country as well. It is the trout of Izaak Walton, and 

 the German names are cerainly inapplicable. In Germany it is known 

 as "bach-forelle", which means "brook trout." It is neither so gamy 

 nor so good a food-fish as our own trouts, though it grows quite large in 

 suitable waters, or those of higher temperatux-e than required for our 

 native trouts. 



It has both reddish-brown and black spots, of a larger size than those 

 of its American cousins. In 1899 a lot of fingerlings were supplied by 

 the U. S. Bureau of Fisheries, to Hon. C. W. Hoffman, who placed them in 

 a pond on his ranch, a mile from Bozeman. Last summer (1903) two 

 were taken from the pond weighing six pounds, a remarkable growth in 

 four years; though this weight was doubtless attained at the expense of
