rains came, bringing the streams to normal level, and from that 

 date on conditions were generally favorable to good work. The 

 egg collections were therefore successful, and more fish Avere pro- 

 duced for distribution than for a number of seasons past. 



Between September oO and October 4. while the drought still 

 prevailed, 38,000 ehinook-salmon eggs and more than 4,000,000 silver- 

 salmon eggs were taken, the collecting season extending from Oc- 

 tober 4 to December 22. The steelhead work at this point also 

 shoAved a satisfactory improvement over that of last season, the 

 collections netting 847,000 eggs of excellent quality. No hump- 

 back salmon were in evidence in Grandy Creek during the year, 

 but in October apj^roximately 275,000 eggs of this species were re- 

 ceived from the Afognak station. A small number was sent to 

 central station at Washington, D. C, for exhibition, Avhile the re- 

 mainder was incubated and the young fish liberated locally in con- 

 tinuance of the policy of attempting the reestablishment of the run 

 of humpback salmon in Puget Sound waters during the so-called 

 '" off year." No chum-salmon eggs were handled at the station dur- 

 ing the year and no fish of this species were taken in the Grandy 

 Creek trap, but it was observed that there was an excellent run in the 

 Skagit River, large numbers of them aj^pearing on the spawning 

 grounds and apparently in excellent condition. 



The output of all species of fish ivoni this station amounted to 

 8.107,890 fry and fingerlings, and upward of 1.000.000 remained 

 in the ponds and troughs at the close of the year. . 



BRINNON (WASH.) SUBSTATIO?s. 



This field station was opened on November 2 for the collection of 

 eggs of the late run of chum salmon. During the spaAvning season — 

 from December 4 to January 8 — eggs to the number of 7,410,000 were 

 taken. After being eyed these Avere sent to other stations on Hoods 

 Canal to be hatched and the progeny were returned to the Duse- 

 wallops River in the advanced fry stage. A^'liile such transfers of 

 eggs and fry involve some extra labor, they undoubtedly result in 

 economy, as the expense of operating pumps and maintaining the 

 Brinnon substation durino- the time required to incubate the eggs 

 and develop the fry would exceed the cost of the transfers by a 

 wide margin. 



DUCKABUSH (AVASH.) SUBSTATION. 



There Avere distributed from this point during the year upAvard 

 of 14,500,000 fry and fingerling fish, the species including chum 

 salmon, silver salmon, and steelhead, and approximately 1,250,000 

 young fish were left in the ponds and troughs at its close. 



In July and August a rack was installed in the Duckabush River 

 near its mouth for the capture of spawning fish from the early run 

 of chum salmon. Because of its low banks rack construction on this 

 river is not an easy matter, and auA' barrier tending to impede the 

 flow of the stream must be carefully watched to preA'ent damage 

 from overflow on to adjacent agricultural lands. During the 

 month of September 10,870,000 eggs were taken, and as this num- 

 ber, together with the eggs expected from the Brinnon collecting 

 station, would fill all the hatcheiw space available, the collections
