 and ~> rainbow trout, all breeders; of ycnirlings, 10,000 brook trout, TOO 

 bIa(ik-spotte(l trout, and 500 Loch Leven trout. Of the black-spotted 

 trout there were also SOO fry and 50,000 eggs. 



The distribution of fish took place between September 1<5 and Novem- 

 ber L*l, 1890, when 20,000 yearling trout wen- furnished to Nebraska, 

 16,000 to South Dakota, and 23,000 to Colorado waters. 



The construction of the new hatchery was sufiQciently advanced by 

 January, 1891, to permit the introduction of the water sup])ly, and 

 about the middle of February the eggs were transferred thereto from 

 the temporary hatclwry. 



The temperature of the water supply in December and January Avas 

 44'^ F. without variation, and in April 43° without change. During

The act approved March 2, 1889, appropriated the sum of $4,000 

 "for the construction of a quarters building at the II. S. Fish Com- 

 mission Station, Baird, California, and its equipments.''' Plans and 

 specifications were prepared for a l.^-story building 30 by 40 feet, with 

 two 12-foot additions. Owing to the isolation of the station it was 

 found impossible to contract for the construction of the building, and 

 it became necessnry to do the work by the purchase of materials and 

 the employment of such men as could be secured in the vicinity. The 

 cost of the l)uilding, including the compensation of the employes, was 

 $3,882.58, and for its equipment and incidental expenses, $117.42. 



The construction of this building'was begun October, 1889, and was 

 completed late in April, the^slow progress being caused by continued 

 rains, which prevented the prompt delivery of materials. The building 

 is substantial and comfortable. 



On July 1, 1889, pre]>aratioiis were begun for the capture of the 

 adult quinnat salmon. The high water in the ])receding March having 

 destroyed the piers, stringers, and racks of the dam in the McCloud 

 River, built for obstructing the ascent of the salmon, the erection of a 

 l)ractically new structure was made necessary. Two new spawning 

 sheds and salmon corrals were built, new seining apparatus provided, 

 the seine-haul cleaned, the roads repaired, the buildings overhauled and 

 painted, and a rotary pump geared to a water wheel, so that a su])ply 

 of 7,000 gallons of water per hour was obtained. 



By driving the salmon upward from the shallows situated below the 

 dam, and the constant use of the seine in conjunction therewith, a suf- 

 ficient number of fish was secured in the first run, August 27 to Septem-
