its equipnient inchidinp; a hatchery buildin«];, a residenci', 24 standard 

 hatching trouglis, and 48 concrete rearing tanks, was phiced in 

 operation. This station handled over 2, 000, 000 sahnon eggs and fry, 

 together witli a number of trout, during the year. It constitutes a 

 spkMulid phint for efiiciently serving the important Rogue River 

 watershed. The Sahnon (Idaho) substation did not succeed in 

 collecting a large number of salmon eggs and for this reason its 

 operations were limited. 



At most of the stations in the Puget Sound territory favorable 

 conditions permitted a fairly successful output, though their total 

 egg collections were somewhat below those of the previous year. 

 The run of sockeye salmon in Baker River, which is cliecked at the 

 Baker Kiver Dam, was somewhat below previous years. Work has 

 continued on a highway leading to the Baker Lake hatchery and has 

 been carried to the point where transportation of supplies by truck 

 is feasible. At the Birdsview (Wash.) Station repeated floods have 

 shown the necessitj^ of diverting water from a nearby creek and work 

 was started at the end of the year on the construction of an entirely 

 new channel, which will relieve the flood difficulty in part. Repeated 

 experimental plants of sockeye salmon in this creek have at last 

 shown returns of a considerable number of this species, and it is 

 evident that a new run of sockeyes has been built up by this means. 

 The substation at Sultan, Wash., formerly operated chiefly for the 

 collection of salmon eggs, was discontinued because of unsatisfactory 

 returns. Over 10,000,000 chum salmon eggs were secured at one of 

 the field egg-collecting stations and incubated in the Duckabush and 

 Quilcene hatcheries. The new Mount Rainier substation, serving 

 the national park of that name, was opened for the first time at the 

 beginning of the year and supplied a considerable number of cutthroat, 

 Loch Leven, and blackspotted trout fingerlings for waters in the park 

 and its vicinity. 



The Quinault (Wash.) station, serving chiefly the sockeye salmon 

 fishery in Quinault Lake, collected 15,500,000 eggs of this species and 

 smaUer numbers of the other varieties. A considerable number of the 

 resulting fry were reared to fingerling size before being distributed. 

 The old hatchery water supply flume was replaced during the year 

 with a 14-inch pipe Ime and a new concrete pipe drain was instafled. 



Great Lakes speciea. —The production of commercial species from 5 

 hatcheries in the Great Lakes area showed an increase for the whitefish 

 but a moderate reduction in output of the other important forms 

 including the lake herring or cisco, lake trout, and pike-perch. As 

 has been the case in the last year or two, the Cape Vincent (N.Y.) 

 station on Lake Ontario obtained only a negligible quantity of the 

 eggs of the commercial varieties. This station therefore concentrated 

 its activities upon the production of smallmouth bass at the main 

 station and game trout at the 3 substations operated under its 

 jurisdiction in New York State. At the latter points fairly successful 

 results were obtained and considerable additional development work 

 was performed at the Cortland (N.Y.) substation. At this point 

 cooperative research in conjunction with Cornell University and the 

 State Conservation Department is being conducted with the purpose 

 of ascertaining basic physiological facts on the nutrition of trout. 

 Put-in Bay (Ohio) station enjoyed an average season with the whitefish 

 and pike-perch and did not undertake to collect the eggs of carp or 

 yellow perch as heretofore.
