Seventy barrels of salmon flesh were salted for fish food, and a considerable 

 quantity of horse meat also was fed. The latter apparently is proving to be a 

 very satisfactory diet. 



Big White Salmon (Wash.) substation. — A combination workshop and garage 

 was constructed during the year. This constitutes the only work of major 

 importance in the way of improvements. A new cedar head trough was in- 

 stalled in the hatchery building, and steps were taken to provide an additional 

 supply of fry trays. The collection of chinook-salmon eggs from the Big White 

 Salmon River was the largest in recent years, a total of 14,906,000 being secured. 

 The eggs were transferred from the racks to the hatchery in the green state, 

 being carried by truck. Excellent results followed this method, and the hatch 

 was normal. A number of eggs were carried successfully in this manner to 

 the Clackamas station, a distance of nearly 75 miles. Spring Creek yielded 

 more than 5,000.000 eggs, which was very satisfactory. This stream has been 

 built up as a salmon stream entirely by artificial propagation, and it probably 

 constitutes one of the most dependable and inexpensive sources for eggs in the 

 Oregon field. Most of the chinook fry were reared to the No. 2 fingerling size 

 before they were liberated in the river. A considerable amount of salted salmon, 

 as well as 3% tons of horse meat, was used in feeding this stock. The marking 

 experiment initiated last year was unsuccessful, but the work was again taken 

 up with the idea of ascertaining the benefits to be derived from holding fall 

 chinook-salmon fingerlings over a considerable period. This station handled 

 a number of brook-trout eggs and distributed 49,000 fingerlings of that species. 

 The work of the station also included the incubation of 100,000 steelhead eggs 

 and 75,000 rainbow-trout eggs for the Klickitat County (Wash.) Game Com- 

 mission. 



Rogue Rixjer (Oreg.) substation. — Minor repairs were made to the plant here. 

 The collection of chinook-salmon eggs was only about half as large as that of 

 the previous year, although fishing started on August 13 and was conducted 

 continuously to September 26. No other eggs were taken at this station, but a 

 consignment of sockeye-salmon eggs was transferred here from the Quinault 

 field and a number of sockeye fingerlings resulting from the previous year's 

 transfer were distributed. 



Applegate Creek (Oreg.) suhstatvan. — Late in August temporary repairs were 

 made to the fish barrier across Applegate Creek. A 60-foot break in the west 

 end of the dam was repaired, and a new trap and pens were constructed. The 

 satisfactory condition of the water during the spawning season of the silver 

 salmon made possible a collection of eggs over three times as large as that 

 of the preceding year. Favorable conditions prevailed during the steelhead 

 run, also, though few fish entered the creek, and in spite of the reconstruction 

 of the barrier the total number of eggs taken was below that of last year. 

 After making the usual shipments of steelhead eggs in the eyed stage, the frj' 

 and the remaining eggs were transferred to the Butte Falls hatchery of the 

 Oregon Game Commission for further development. This permitted the closing 

 of the Applegate Creek station for several months and resulted in a reductioD 

 in the cost of operations. 



Salmon (Idaho) substation. — At the beginning of the year 285,000 chinook- 

 salmon fingerlings were being carried. Part of these were distributed, and the 

 remainder were held for a marking experiment. While the rim of salmon in 

 the Lemhi River was a month late, 4,000,000 eggs were taken. A number of fish 

 apparently spawned in the river below the rack. The eggs taken in this river 

 were eyed locally and were then transferred to the Salmon (Idaho) hatchery 

 for futher development. Sixty thousand fall and 65,500 spring chinook-salmon 

 fingerlings were marked and liberated in the experiment mentioned above. No 

 fish were liberated from the station until they had reached a length of 2 inches. 



In connection with the work in this field a new collecting station for rain- 

 bow-trout eggs was opened at AVilliams Lake. Idaho. From April 23 to May 19 

 over 1,000,000 eggs of this species were secured, and after developing them 

 to the eyed stage they were transfei-red to the Salmon hatchery. 



Baird (Calif.) Station and Substations 



(W. K. HancocKj Superintendent) 



The major improvements made at the Baird station were the painting of 

 several of the buildings and minor alterations and repairs. The fall run of 

 Chinook salmon in the McCloud River was very light, and a number of those
