 these terms. In Germany it is bachforelle ; in Italy, trota; in 

 France, truite. In the United States it is known as the brown 

 trout and von Behr trout, the latter in honor of Herr von Behr, 

 president of the D cut seller Fischerie Tercin, who has been very 

 active in the acclimation of the fish in America. 



Distribution. The brown trout is widely distributed in conti- 

 nental Europe and inhabits lakes as well as streams, specially 

 in Norway and Sweden. Tributaries of the White sea, the Bal- 

 tic, the Black- sea and the Caspian contain this species. In Great 

 Britain it lives in lakes and streams and has reached a high 

 state of perfection; in Germany and Austria, however, the trout 

 is a characteristic fish, and our supply has been drawn prin- 

 cipally from the former country. Moreau found it at an eleva- 

 tion of 7000 feet in the Pyrenees, and a color variety is native 

 to northern Algeria in about 37 north latitude. In the United 

 States the brown trout has been successfully reared in Colorado 

 at an elevation of nearly 2 miles above sea level; it is now well
