Forest Service. Further investigation of streams and spawning grounds was 

 conducted during the j^ear. Silver sahnon and steelhead salmon eggs were suc- 

 cessfully collected in Baker River below the dam and transferred to the Birds- 

 view station for incubation. A highway to the Baker Lake station from the 

 Mount Baker Forest boundary is now being constructed by the United States 

 Bureau of Public Roads, and by the fall of 1932 the old pack-horse trail between 

 Baker Lake and Concrete can be abandoned. Further effort was made during 

 the year to establish a run of sockeye salmon in the Lyre River. 



Birdsview (Wash.) station. — Minor repairs and improvements were made to 

 two of the station cottages, and the interiors of the mess-house cottage and small 

 cottage were repainted. Two new Ford trucks and a concrete mixer were added 

 to the station equipment. The year opened with a considerable number of sock- 

 eye salmon, steelhead salmon, and black-spotted trout fingerlings on hand. 

 Fifty thousand of the first-named species were set aside for the continuation of 

 the experiment to determine whether age or size of the fish at the time of release 

 is the factor governing its return, and 34,200 were planted in streams having lakes 

 at their head. The black-spotted trout fingerlings and a number of the steelhead 

 salmon were distributed in Mount Rainier National Park waters. The remainder 

 of the latter species were distributed locall3'' and supplied to applicants late in 

 the fall. 



On account of low water in Grandy Creek during the early fall, egg collections 

 in the course of the year were confined to operations with the silver and steel- 

 head salmons, of which only small numbers were obtained as compared with 

 previous years. However, silver salmon eggs for stocking the Birdsview hatchery 

 to the number of 1,740,000 were collected in Baker River in December and the 

 stock of steelhead eggs from local waters was supplemented to the extent of 

 330,000 secured from the same source. The station also received and handled 

 eggs of the sockeye, chinook, and humpback salmon and of the black-spotted 

 and rainbow trout. Shipments of chinook and steelhead salmon eggs were fur- 

 nished by the station to applicants in the State of Washington and in Hawaii. 

 Feeding operations were conducted to the full capacity of the station and fluke- 

 infected liver was successfully used, at a considerable saving in cost as compared 

 with fresh liver. AH fry and fingerling fish produced were liberated locally except 

 98,700 sockeye sahnon, retained for the marking experiment, 71,500 rainbow 

 trout fry, and all of the steelhead eggs, fry, and fingerlings. This stock was 

 carried over the year for distribution later in the season. 



Baker Lake (Wash.) substation. — Such minor repairs were made to buildings 

 and equipment as were necessary for the proper maintenance and operation of 

 the station. Of the 1,036 sockeye salmon passed over the dam at Concrete, 859 

 were caught at the station and from them 1,183,000 eggs were obtained. Of 

 these 100,000 in the eyed stage were transferred to the Birdsview station. The 

 fingerling fish produced from the remainder, together with 955,000 fry resulting 

 from a shipment of sockeye eggs received from the Yes Bay (Alaska) station, 

 were liberated in Baker Lake prior to the close of the fiscal year. Of the 16,263 

 silver salmon passed over the dam at Concrete, 2,103 were caught in the station 

 trap. From them 1,322,000 eggs were secured and transferred in the eyed stage 

 to the Birdsview station. For the purpose of stocking a number of mountain 

 lakes in the vicinity of the station, 50,000 eastern lirook trout eggs were received 

 during the winter from the Washington State Fisheries Department; and 40,000 

 Loch Leven trout eggs, for stocking Baker Lake, were received from the Boze- 

 man (Mont.) station. The fingerlings resulting from these two lots of eggs were 

 on hand at the close of the year. 



Duckabush (Wash.) substation. — All station buildings and equipment were 

 maintained in good condition throughout the year. During August a temporary 

 rack was again installed near the mouth of the Duckabush River for securing eggs 

 of the early-run chum salmon, and when the run was over it was again removed 

 from the river. About 6,000 pounds of salted salmon were prepared for fish food, 

 for use at the Hoods Canal and Birdsview stations. The early run of chum salmon 

 in Duckabush River did not exceed 50 per cent of normal. Practically all of the 

 5,529,000 eggs secured from the late run of this species were collected at Walcotts 

 Slough, operated conjointly by the Duckabush and Quilcene stations. Only 

 237,000 eggs of the silver salmon and 37,000 of the steelhead were obtained at 

 the permanent trap. The supply of the former species was increased by the 

 receipt of 1,075,760 eggs from the Quinault station; and 753,000 eggs of the 

 chinook salmon were shipped in from the Little White Salmon hatchery, with 

 the view of continuing the experiment undertaken in 1925 for increasing the run 

 of that species in the Duckabush and Docewallips Rivers. All fry and finger-
