REPORT OF COMMISSIONER OF FISH AND FISHERIES. 59 
A fish-cultural station planned to meet all the requirements must be very extensive 
and complete in all its appointments, and will involve larger expenditure than would 
be required for a station devoted exclusively to the production of whitetish or the 
salmonidwe. The hatchery must be commodious, providing at once for the hatching 
of 100,000,000 of whitefish and for the incubation of 1,000,000 salmon ova. It must 
also provide trough accommodations for holding 1,000,000 salmon fry for some weeks 
after they begin feeding. Quarters, offices, storage rooms, and shops must be erected ; 
an extensive system of ponds for rearing the salmon must be constructed, for none 
would be released in open waters until they were of sufficieut size to have compara- 
tive immunity from capture by other fish. 
At the first installation of the station and for several years it would be necessary 
to draw our supplies of whitefish ova from our collecting stations on the upper lakes 
and our salmon ova from Maine. With the improvement of the fisheries we should 
expect to find our eventual source of supply in Ontario waters, and the location of 
the station should be with reference to this. Wherever placed it should be conven- 
ient to transportation routes, and should control a gravity water supply which should 
be without stint or measure. 
The cost of such a station as I have indicated, complete in all its appointments, 
would not be less than $20,000, exclusive of cost of site and water franchises, and for 
its maintenance there would be required an appropriation of $9,000 per annum. 
Respectfully, 
MarsHaLt MCDONALD, 
U.S. Commissioner of Fisheries. 
Hon. Lrvi P. Morton, 
Vice-President. 
A consideration of the report resulted in an appropriation of $5,000 in 
the bill approved March 3, 1891, providing for the sundry civil expenses 
of the Government during the fiscal year ending June 50, 1892. This 
appropriation not being available till July 1, 1891, action in the matter 
was necessarily deferred. 
Vermont.—On January 12,1891, Hon. W. W. Grout, Representative 
from Vermont, introduced in the House of Representatives a bill pro- 
viding the sum of $15,000, “for the purchase of ground, construction 
of buildings and ponds, and the purchase of the equipment for a fish- 
hatchery and rearing station to be established in the State of Vermont, 
at a place to be designated by the United States Fish Commissioner.” 
The bill was referred to the Committee on Commerce, by which it was 
returned to the House on January 30, with the recommendation that it 
pass. The bill as presented failed to become a law, though provision 
for the station was made in the sundry civil bill approved March 3, 
1891. The appropriation not being available till July 1, 1891, no action 
could be taken till after that date. 
Montana and Gulf States.—Congress, by act approved March 3, 1891, 
provided the sum of $2,000 “ for investigation respecting the advisa- 
bility of establishing a fish-hatching station in the Rocky Mountain 
region in the State of Montana or Wyoming, and also a station in the 
Gulf States.” Instructions were prepared covering the extent and 
character of the investigations and early in the following July, when 
the appropriation became available, Prof. B. W. Evermann, assistant 
in the Division of Scientific Inquiry, was charged with the same.
