REPORT OF COMMISSIONER OF FISH AND FISHERIES. XXXIII 
DULUTH STATION, MINNESOTA. 
As announced in the last report, the hatchery building at Duluth 
was let to contract on May 21, 1888. The construction of the building 
was begun under the supervision of Mr. George Tolbert. On Septem- 
ber 9, 1888, Dr. B. O. Sweeny was appointed superintendent, and re- 
ported at the station. The completed building was accepted from the 
contractors, Messrs. James Carlisle & Sons, of Minneapolis, January 
15, 1889, and was received into the custody of the superintendent. 
The grounds are located on the left bank of Lester Biver, at its 
mouth, where it enters into Lake Superior. The hatchery is built of 
wood upon stone foundations. It is divided into three portions : the 
front is 38 feet wide and 21 feet deep ; the remainder of the building is 
60 feet long and 30 feet wide, except the rear 18 feet, which is 34 feet 
wide. The front and back ends are two stories high and connected 
by a low attic. The stone basement contains the coal room, pump and 
boiler room, etc. 
On the' first floor is the hatching room, 60 by 32 feet, located in the 
back part of the building, facing the lake. In a room occupying the 
rear gables it is intended to place an elliptical tank, into which water 
will be pumped from the lake until a supply can be obtained from 
Lester Biver. From this tank the water will be distributed through 
pipes to the hatching and rearing apparatus in the room below. The 
present water supply is pumped from Lake Superior at a point nearly 
opposite to the hatchery. It is intended in the future to construct a 
dam in Lester Biver and convey the water through a flume to a reser- 
voir in the hatchery grounds. Permission has been obtained from the 
Duluth and* Iron Bange Bailroad Company to support this flume upon 
their bridge where it crosses Lester Biver. The hatchery is supplied 
with 400 jars, capable of accommodating 60,000,000 whitefish eggs. It 
is intended to establish collecting stations for whitefish eggs in Lake 
Superior, but arrangements for this could not be perfected the pres- 
ent season. 
The following consignments of eggs were received and hatched at the 
station during the season :

in Lake Superior in localities adjacent to the station. The fry obtained 
from the Von Behr trout and salbling eggs were held at the hatchery 
until the end of June and then transferred to the Minnesota State
