REPORT OF COMMISSIONER OF FISH AND FISHERIES. (mee 
These eggs are obtained under very adverse conditions, as they 
must be hauled 35 miles over the roughest kind of mountain road and 
then transferred by rail a distance of 250 miles, with the thermometer 
ranging from 100° to 110° in the shade. During June, 1,317,000 eggs 
were collected at these lakes and taken to Leadville. The loss on 
them to the close of the year was 1,800, or about 0.12 per cent. 
The fish and fry on hand at the close of the year is shown-by the

SPEARFISH STATION, SOUTH DakoTa (D. C. BOOTH, SUPERINTENDENT). 
During the summer the special appropriation of $5,500 was expended 
in improving the grounds, building ponds, constructing a storm chan- 
nel for protecting the lower grounds from flood, and laying a 4-inch 
iron pipe from the upper spring to the hatchery, a distance of 700 feet. 
The fish reared at the station were distributed in the fall to appli- 
cants in South Dakota, Wyoming, and Montana, the output being 
210,000 brook trout and 10,000 Loch Leven trout. 
With the approach of fall arrangements were made, as in previous 
years, for collecting eggs of the brook and Loch Leven trout from 
publie and private waters in South Dakota and Wyoming, and a 
temporary station for eying eggs was established at Sand Creek, 
Wyoming. Several thousand trout about 10 inches in length were 
handled here, yielding 302,200 eggs, which after being eyed were 
transferred to Spearfish. The water temperature at this creek stands 
uniformly at 54° F. throughout the year, so that the eggs were ready 
for shipment in 28 days. Collections were also obtained from ponds 
controlled by private individuals, and these, with the eggs produced 
by the brood fish at the station, gave a total collection of 1,062,650 
brook-trout eggs and 50,470 Loch Leven eggs. 
Of the brook-trout eggs, 201,000 were shipped as follows: 100,000 to 
Bozeman, Mont.; 50,000 to Duluth, Minn.; 51,000 to the Wyoming 
Fish Commission. The rest were hatched at the station and produced 
654,000 fry, of which 250,000 were returned to the owners of the brood 
stock. On the remaining 408,000 there was a loss during the spring of 
133,000, and 195,000 were planted in waters of South Dakota, leaving 
80,000 on hand at the close of the year. 
The Fish Commission’s share of Loch Leven trout eggs amounted 
to 36,100. These were hatched and 30,000 young fish were distributed 
during the spring, leaving 5,000 on hand at the close of the year.
