114 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
aquatic birds, many of which attacked the pond stock, capturing some 
of the spawning fish from off their nests of eggs. For nineteen days 
it was necessary to have the station patrolled by one of the employees, 
during which time eight fish-hawks were killed. This station is not 
only infested with crawfish, but by many wild animals, and constant 
vigilance on the part of employees is necessary. The records show the | 
following as having been caught during the fiscal year: Kingfishers, 9; 
wild duck, 52; gull, 1; grebe, 9; water-hens, 11; fish-hawks, 9; bittern, 
15; “anal 3; egret, 1; owl, 1; turtles, 43; snakes, 98; frogs, 794; 
muskrats, 7; raccoon, 1; mink, 1; water rats, 15; crawfish, 267,460. 
The black bass began to prepare nests toward the end of April, and 
by May 15 as many as 15,000 young were transferred from the nests to 
unoceupied ponds. <A larger number could have been transferred had 
the pond area been available. The tench, which spawn at this station 
at two years of age, deposited their eggs by May 15. The golden ide 
spawned profusely April 7, but without effect. An attempt was made 
to artificially handle a portion of the eggs, but without success, all 
being found covered with fungus at the expiration of ten days. The 
eggs flowed freely and were apparently in good condition. In color 
they were dark brick-red. In August, 1892, the rock bass were found 
to be spawning for the second time in that calendar year. The channel 
catfish again, for the third season, failed to deposit eggs, for reasons 
unknown, every care having been bestowed upon them. 
The rainfall for the year was 37.3 inches, the fall of snow being 10.75, 
The maximum air temperatures in July and August were 105° and 1029, 
respectively, the lowest temperatures being reached in December and 
January, the thermometer registering 8° below zero in the latter month. 
The extremes of temperature in trout ponds were 80° maximum and 
32° minimum; in black-bass ponds, 88° and 36°, Ice gathered from 
the ponds and stored in December was 6 inches thick, and comprised 
about 60 tons. The fish remaining on hand June 30, EE of all kinds, 
are represented in the statement which follows:

LEADVILLE STATION, CoLoRADO (H. D. DEAN, SUPERINTENDENT). 
Work was confined to the salmonide, the fish liberated being of 
yearling size, and the output larger than in any previous year, 
amounting to 178,900 fish and 60,000 eggs. 
In addition to repairs to the old hatching-house, 14 new rearing- 
ponds were prepared, the smallest being 5 feet wide and 15 feet long,
