from them were equal in vigor to those more normally developed. 

 So far as is known such an occurrence has never before been experi- 

 enced. 



Zipper Clackamas iOreg.) substation. — The flood of January 6, 1922, 

 practically wrecked this substation, destroying its buildings and ren- 

 dering the station site quite unfit for the prosecution of fish-cultural 

 work. However, with the view of securing all available eggs of the 

 valuable chinook salmon, a small building was constructed in advance 

 of the spawning season of 1923 to serve as an eying plant, lumber 

 for the purpose being salvaged from the wreckage. The usual suc- 

 cess was met with in the collection of eggs, and after developing 

 them to the eyed stage they were transferred to the Clackamas sta- 

 tion and the substation was closed for the season. 



Little White Salmon ( Wash.) substation. — During the year some 

 important changes were made in the station water supply at this 

 point to insure protection against the storms and floods to which 

 this section of the country is subject. The old flume line was aban- 

 doned and a new line blasted out of the cliflf on the south shore, 

 concrete abutments being constructed to protect its intake. A run 

 of spawning chinook salmon appeared at the racks at the usual time, 

 and egg collections were prosecuted without interruption from Sep- 

 tember 20 to October 9. The run appeared lighter than usual, and it is 

 believed the intensive fishing conducted in the Columbia River had 

 some effect on its size. Eggs to a total of 14,415,000 were taken, 

 and also 414,000 of the chum salmon. Prior to their liberation the 

 fingerling fish resulting from these collections consumed several tons 

 of salted salmon in addition to 5}4 tons of canned salmon and 2 tons 

 of beef spleen. 



Big White Salmon ( Wash.) substation. — Brood chinook salmon in 

 very fair numbers appeared on the usual spawning areas in the Big 

 White Salmon River and Spring Creek, and from them 7,205,000 eggs 

 were collected. A hole cut in the rack by beavers during a period of 

 turbid water, when the damage was not discernible, permitted some 

 of the fish to escape, tliereby reducing the collections to some 

 extent. In addition to salmon propagation, a considerable amount 

 of work was done for the State of Washington in incubating eggs of 

 the brook trout, rainbow trout, the so-called "silver trout," and the 

 steelhead salmon. The young fish resulting from this stock were also 

 held and cared for until the distributions could be made by State 

 employees. 



nogue River (Oreg.) substation. — The output of this station was 

 6,136,700 fingerling fish, and approximately 1,000,000 eggs and fry 

 were still on hand at the end of the year. The work was concerned 

 with the chinook, silver, sockeye, steelhead, and landlocked salmons, 

 and the black-spotted trout, consignments of eggs of the two last- 

 named species being received from Maine and the Yellowstone 

 National rark, respectively. About one-third of the chinook-salmon 

 eggs collected were secured on the new spawning grounds in Big 

 Butte Creek. The run of silver salmon was well above the average, 

 and 2,235,300 eggs were obtained and incubated. For several seasons 

 past eggs of the steelhead salmon have not been available in large 

 numbers at this point. The collection during the vear amounted 

 to 506,600.
