40 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
Brook trout.—The spawning of the brook trout covered a period of 
eighty-five days, commencing October 14, 1889, the number of eggs: 
obtained being 322,000, In addition to these there was a consignment 
of 25,000, received January 25 from the Leadville Station. The eggs 
from brood fish were derived as follows: From 478 females 2 and 3 
years old, 269,300; and from 224 others 18 ménths old, 52,700. These 
were transferred in ten shipments 265,000 eggs. In aauititn to these, 
75,000 were retained at the station, of which 25,000 were for stocking 
aes waters of the Yellowstone National Park. The inconsiderable loss 
in hatching operations is ascribed to the development of the eggs in the 
earlier stages on gravel. Of brook trout yearlings, 7,500 were deliv- 
ered for liberation in various waters. 
Loch Leven trout.—From 500 females maintained at the station 
291,100 eggs were obtained October 25 to December 50, 1889. Com- 
mencing January 20, and continuing thirty-five days, 162,000 of these 
eges were transferred, shies 75,000 others were held for rearing. A con- 
signment of 13,000 eggs was received from Germany on March 11, 1890, 
but these heyelaned aie about 25 per cent of fry. The distribution of 
yearlings commenced September 17, 1889, 10,000 being liberated. 
Lake trout.—The eggs taken aIoUAEA to 3,954,000, an excess of 
600,000 over any previous season. The transfers from these eggs 
amounted to 2,600,000, and 200,000 were held to be hatched. Of those 
transferred, 1,000,000 were sent to Duluth Station; of those retained, 
100,000 were held for the Yellowstone National Park. In February, 
1890, 13,152 yearlings were turned over to car messengers for liberation. 
tan trout.—Results with the rainbow trout, as in preceding 
years, were-unsatisfactory. From 2,500 brood fish, one-fifth of which 
were 3 and 4 years of age and the remainder 2 years of age, only 119,000 
eggs were secured, and of these only 52,600 survived to the age when 
the eye spots are visible. 12,500 eggs were sent to the Wyoming Fish 
Commission, and from the remainder only 5,000 fry were produced. 
19,143 yearlings were distributed through the messenger service. 
Landlocked salmon.—A consignment of eggs from Schoodic Station, 
received February 28, 1890, was wholly without results. 
1890-91. 
This station, one of the first established by the Commission, and at 
which the work of the propagation of whitefish on the Great Lakes 
was inaugurated, has for many years been occupied under rental. The 
company owning the property having decided to sell the same, the 
Commission was given the opportunity to buy it. In view of its 
advantages, Congress was asked to make the necessary provision for 
its purchase. This request was met by an item in the. sundry civil 
bill, approved August 30, 1890, appropriating $15,000 “for the pur- 
chase of the grounds and buildings located at Northville, Mich., now 
occupied by the U.S. Fish Commission, under iease as a fish-hatching
