fish commissions and private individuals. The balance were hatched 
at Detroit and produced 77,000,000 fry, which were liberated during 
the month of April. 
On March 10 the Alpena hatchery was opened for the reception of 
31,000,000 white-fish eggs and 1,000,000 lake-trout eggs, which had 
been sent to that point to be hatched and planted in Lake Huron. This 
work was superintended by Mr. Howard Mancha and was completed 
by May 5, when the station was closed. 
In order to reduce the expense of distribution, and for the purpose 
of stocking Lake Superior, 20,000,000 white-fish eggs and.750,000 lake- 
trout eggs were transferred to the State fish-hatchery at Sault Ste. 
Marie, arrangements having been made with the State fish commis- 
sion for its use from February 1. The white-fish hatched in May 
with a loss of 10 per cent, and were all planted in Lake Superior with 
the exception of 3,000,000, which were deposited in Lake Huron, near 
Detour. The lake-trout eggs yielded 700,000 fry, the loss amounting 
to only 50,000. 
The water at this point during April ranged from 382° to 37° the aver- 
age for the month being about 333°. The average for the month of 
March was 32°. The water was shut off from the hatchery several 
times during the season, but, as it was only for short intervals, no 
apparent damage was done. 
All the lake-trout eggs hatched by this commission at Alpena and 
Sault Ste. Marie were transferred from Northville, and the white-fish 
eges were shipped from the Detroit River fisheries. 
The following table shows the number of eggs collected at North- 
ville and substations, and the number of eggs and fish shipped during 
the fiscal year, including accessions by transfer from other stations:

The hatching apparatus was overhauled and repaired during the 
summer, and a number of improvements to the station grounds were 
made, including the planting of a large number of willows and pop- 
lars and the completion of roads. Arrangements were also made 
with the water and light commissioners of Duluth to furnish the sta- 
tion with water from Lake Superior, this being very essential in hot 
weather for reducing the temperature of the river water.
