and clium-salmon eggs from Brinnon were incubated with the locaP 

 collections, and during the spring 92,000 steelhead-salmon eggs were 

 collected and hatched. 



Quilcene ( Wash.) substation. — Between September 3 and October 11 

 6,365,000 eggs were taken from the early run of chum salmon appear- 

 ing below the temporary racks installed in the Big Quilcene and Little 

 Quilcene Rivers. A late run of this species occurred in December, 

 and eggs were taken at intervals during most of that month, the total 

 amounting to 1,605,000. The silver-salmon run extended from No- 

 vember 23 to February 12 and yielded 1,520,000 eggs. Eggs of the 

 silver salmon from Birdsview and of chum salmon from Brinnon were 

 incubated at Quilcene with the local collections. During the run of 

 spawning steelheads in the spring there was a period of unusually low 

 water, this being the only unfavorable climatic condition experienced 

 at this point in the course of the year. 



The only important improvement at this substation during the 

 year was the laying of a 12-inch wood-stave pipe line to connect the- 

 supply tank and rearing ponds, this line taking the place of the old 

 trestle flume, which was unsightly and of insufficient capacity to meet 

 the requirements. 



Sultan, ( Wash.) substation. — The fish-cultural work at this substa- 

 tion suffered more from adverse weather conditions than at any 

 other point in the Washington field. In the fall, when most of the 

 important fishes were spawning, the prevailing low-water stages 

 interfered materially with the work, and serious floods in the course 

 of the winter wrecked the traps, undermined the intake and head 

 gate, and entirely cut off the hatchery water supply. Then followed 

 another period of low water at the spawning time of the steelheads, 

 greatly reducing the egg collections and causing serious inconvenience 

 in the hatchery. 



This substation is located on a tributary of the Skyhomish River, 

 and large numbers of both chinook and humpback salmon were 

 present in that stream. Because of the conditions encountered, 

 however, only a comparatively few fish were able to ascend the 

 tributary to their customary spawning areas. Owing to this fact 

 the egg collections of each species were practically negligible, amount- 

 ing to 610,000 and 30,000, respectively. In the case of the chinook 

 salmon the spawning period extended from September 21 to Novem- 

 ber 3, while the humpback eggs were taken between September 24 

 and October 8. While the egg collection of silver salmon was smaller 

 by 50 per cent than last year, it was larger than there was reason to 

 expect in the face of prevailing conditions. Between November 3 

 and January 30, 2,180,000 eggs of this species were secured. 



On February 12 Elwell Creek attained its highest recorded stage. 

 The traps were wrecked and the intake dam and head gate under- 

 mined throughout their entire length. Because of the high level of 

 the creek at this time, water continued to flow through the flume to 

 the hatchery, but following a rather sudden lowering of the air 

 temperature on the night of February 15 the water in the creek 

 dropped a foot or more, cutting off the hatchery supply. This 

 necessitated the immediate removal of all baskets of eggs undergoing 

 incubation to a shallow bed in an eddy of the creek, which had been 

 previously prepared for the purpose. The fry and fingerling fish on 

 hand were of necessity liberated in eddies of the creek. By the 16th
