REPORT OF COMMISSIONER OF FISH AND FISHERIES. 103 
NORTHVILLE STATION, MICHIGAN (FRANK N. CLARK, SUPERINTENDENT). 
The operations consisted largely in handling eggs derived from brood 
fish held in ponds. The Alpena Station, however, being operated under 
the same superintendency, a certain amount of the work consisted in 
handling eggs of lake trout and whitefish. Improvements consisted 
chiefly in procuring an additional water supply from a creek and the 
construction of a new series of forty rearing-ponds, ten of the latter 
being completed before the year closed. There was a slight increase in 
the take of eggs and their quality was excellent. Attempted transfers 
of trout eggs to the Government of Japan were unsuccessful. 
Atthe beginning of the year young fish on hand, in process of rearing, 
consisted of the following: Lake trout, 75,000; brook trout, 59,000; 
Loch Leven trout, 70,000; Von Behr trout, 64,000; total, 268,000. 
The fish remaining on hand October 24, by actual count, were as fol- 
lows: Lake trout, 38,644; brook trout, 34,986; Von Behr trout, 14,265; 
Loch Leven trout, 9,926; total, 97,821. 
In- consequence of intensely cold weather, subsequent losses reduced 
the numbers, those distributed being 23,600 lake trout, 19,900 brook 
trout, 3,400 Loch Leven trout, and 150 Von Behr trout. Some were 
retained for brood stock. In November a portion of the yearling fish 
were transferred from rearing-troughs to the new rearing-ponds. The 
cold weather in January so injured these ponds that it was necessary to 
make repairs after the disappearance of ice. The distribution occurred 
between January 24 and March 20. 
Contributions to the World’s Fair exhibit, Chicago, occupied quite ¢ 
portion of the time of the superintendent, live specimens of the various 
trout mentioned, and of the black-spotted and rainbow varieties, of all 
sizes and ages from fry to four years old, being furnished. In addition, 
64 glass jars of eggs and young of the various species, from earliest 
stages to 12 months’ age, were furnished. Pike-perch eggs were also 
collected and forwarded. 
In September, in advance of the egg-collecting period, hatching- 
troughs, trays, and other equipment were overhauled and asphalted, 
150 new trays being provided. 
Lake trout.—Between November 11 and 26 there were received from 
the Alpena Station, in four consignments, 2,051,000 eggs of lake trout. 
Their condition was only fair. Of these eggs, 955,000 were forwarded 
by express shipment, as follows:
