26 REPORT OF THE COMMISSIONER OF FISHERIES. 
The Cold Spring, Ga., hatchery doubled its black-bass output of 
the preceding year. The gain is attributed to new brood stock and 
to thd location of.a new and valuable collecting field at Milltown, 
Ga. With nominal expenditures for fixed equipment at Milltown, 
the superintendent predicts that the output another year can be 
increased by 400 per cent. 
The Orangeburg, S. C., station has proved wonderfully successful 
in black-bass propagation, distributing during the sprmg months 
135,000 fingerlings, and at the end of the fiscal year many thousands. 
remained in the ponds for fall assignment. This is the first season’s 
fish-cultural operations at the Orangeburg station, and the results 
portend conspicuous efficiency for the future. 
Pond-cultural operations at the combmation trout and _ bass 
stations were practically a duplication of former years. At St. 
Johnsbury, Vt., the superintendent has taken up the collection of 
smallmouth black-bass fry from Crystal and Barlsthin Lakes, trans- 
lanting them in the station ponds to be held until they are of finger- 
ae size. The collections are from lakes that the State officials desire 
to reserve for trout and salmon, and liberal plants of the latter are 
made in return for the bass fry collected. While the output is rela- 
tively small as compared with that of the exclusively pond stations, 
the availability of bass for special distribution in New England is of 
such importance that the output is of great value and comes near to 
satisfying the demand for that species in that region. 
Besides the commercial fishes before mentioned, the Northville, 
Mich., station hatched and distributed 771,000 brook-trout fry, 
190,000 rainbow-trout fry and fingerlings, and a few thousand gray- 
ling fry. The eggs of the first named were purchased and the others 
were transferred from stations of the Bureau. It also produced in 
the station ponds during the year 326,125 fry and fingerling small- 
mouth black bass. 
One of the most successful features of pond culture has been the 
noteworthy production of the smallmouth black bass at Northville. 
At this station 600,000 fry were hatched; of these 288,000 were imme- 
diately shipped and the remainder held for rearing. At the close of 
the year 38,125 had been distributed, and it is estimated that 3 car- 
loads remained in the ponds for later shipment. With this stock the 
Bureau will be able to quite thoroughly supply all old applications 
for this species in Michigan, Wisconsin, Minnesota, and Ohio. Such 
favorable conditions for smallmouth black-bass propagation as are 
apparent at Northville will be taken advantage of and the facilities 
improved in order that the output may be further enhanced. This 
species is very difficult to propagate under average conditions, and 
as the demands for it are annually increasing every opportunity will 
be taken advantage of to meet it. 
MARINE FISH-CULTURAL WORK. 
The output of all species propagated at the marine stations waS 
materially larger than in the preceding year, with the exception o 
the lobster. The work at these stations was conducted along the 
usual lines and on the whole was successful, though it was hampered 
to some extent by unfavorable climatic and other uncontrollable 
conditions. .
