uable acquisition to our fish-food. The fact that this fish is 
found in waters very much warmer than those inhabited by 
their cousins in the Atlantic, induced us to devote our ener- 
gies more particularly to them. But the return of the Penob- 
scot salmon in the Delaware Diver, and the capture of a large 
Penobscot salmon near Spesutie Island, has given us more 
confidence in the adaptability of Maryland waters to the Eas- 
tern variety. 
Hitherto we have hatched all of the eggs of the salmon 
family in the hatching-house at Druid Hill Park. When the 
young fish were sufficiently advanced to warrant their distri- 
bution, they were transferred to the upper waters of the 
streams of the State, and in the distributions we have endeav- 
ored to reach points as high up the streams as practicable, 
where the water was colder and more likely to fill the re- 
quirements of the young fish. These transfers were attended 
with considerable labor and difficulty, and sometimes with 
some loss of fish. We therefore deemed it of sufficient im- 
portance to establish a temporary station at the head waters 
of the Potomac, where the fish intended for that stream could 
be hatched and turned loose in the river adjacent to the hatch- 
ing-station. By this method we would avoid the necessity of 
moving the fish and endangering their safety. Accordingly, 
on the arrival of 500,000 eggs issued to the Maryland Com- 
mission by the U. S. Commissioner, we transferred 200,000 of 
them to the upper waters of the Potomac, in Garrett County,, 
where we improvised a temporary hatching-station. The locality 
selected was on a farm belonging to Judge Dobbin, known as 
Kitzmiller’s farm, on the north branch of the Potomac, several 
miles above Fort Pendleton. A pool immediately below a 
fall of about four feet in the river was selected. In this pool 
were placed a number of floating barges, in which trays con- 
taining the eggs were deposited. The water from above the 
falls was led to these barges by a trough properly protected 
by wire grating which discharged the water on the top of 
barges, the latter being provided with wire bottoms so that the 
water passed through the trays and out at the bottom. The 
trough and barges were so arranged that they would rise or
