THE BROWN TROUT. 
The Brown Trout of Europe, Salmo fario, has been successfully intro- 
duced into our waters by the U. S. Fish Commission. 
Eggs were first received from Herr Von Behr, the President of the 
Deutsche Fischerei-Verein, in the winter of 1882-’83, and were sent 
directly from New York to the station at Northville, where they arrived 
February 18. These were successfully hatched out by Mr. Clark by the 
middle of March, and early in April were planted by him in a branch of 
the Pere Marquette River of Northern Michigan. 
Early in 1883 another lot of eggs was sent to Mr. Mather as a personal 
present by Herr Von Behr. Most of those kept at this station died, but 
those sent to the Northville Station and to the station of the New York 
Fish Commission at Caledonia were reported as doing well. In 1884 
Herr Von Behr sent an additional gift, this time to the U. S. Fish Com- 
mission, in care of Mr. Mather, and a lot of 10,000 was received from 
England. These did better than those of 1883, and many were distributed 
to various New York waters. 
On the 21st of February Mr. Mather forwarded to Washington 2,000 of 
the large kind of Salmo fario, and g,o0oo of the small variety. These 
were transferred to the Wytheville Station, and were hatched with fair 
success, but all died before beginning to eat. 
A few of the German trout reared at the Northville Station spawned in 
December, 1885, and 8,000 eggs were obtained. Two lots of eggs, 23,000 
in number, were forwarded from the Cold Spring Harbor Station, the 
second lot of which (13,000) arrived in poor condition. From these 
31,000 eggs, 20,000 fry were hatched, which were retained at the station.
