extremely warm weather. The fall run was not larg^e because the 

 creek was ver}^ low, while at the same time the Sacramento was several 

 feet above the low-water mark. The run began during the last week 

 in October, and fishing commenced October 30 and continued at inter- 

 vals until the close of the season on December 2, when 2,561,000 eggs 

 had been secured from 451 female salmon. The loss during incubation 

 was 141,000 eggs, or 0.055 per cent. All of the eggs were shipped to 

 the California Fish Commission — 1,000,000 to the Price Creek hatchery 

 and the remainder to Sisson, The method of fertilization was the 

 same as at Baird and Battle Creek. 



As it has been found impossible to secure eggs from the summer 

 run of lish at the Mill Creek Station, during the spring temporary 

 racks were constructed across the mouth of the creek in order to turn 

 the salmon back into the Sacramento River with the hopes that a large 

 proportion of them would continue up the river and on to Baird Sta- 

 tion, where the water is colder and the eggs can be taken. A large 

 run of salmon passed up the river during Maj^ and June, and the fish 

 were continuall}" fighting the racks, but all were compelled to return 

 to the river. 



Clackamas Station, Oregon (J. N. Wisner, in Charge). 



Mr. E. N. Carter, who was in charge of the station for the first six 

 months of the year, having been relieved, Mr. J. N. Wisner, field 

 superintendent, was placed in charge for the balance of the year, and 

 on February 15 Mr. Carter was transferred to St. Johnsburj^, Vt. 



The initial work of the year consisted in the care of the few fish on 

 hand at the end of June, cleaning up of the station buildings, and the 

 construction of a fence around the premises. On July 24 the con- 

 struction of the rack across the Clackamas River a short distance below 

 the station was undertaken and the work completed earl}^ in August. 

 Owing to the fact that about 2,000 cords of wood were being floated 

 down the river, it was necessary to construct a boom above the rack 

 on either side of the river to a point in the rack where a gate was 

 made to allow of its passage. This gate was constructed of 1-inch 

 boards, 4 inches wide, placed with their edges to the current and 

 hinged to an iron rod below the surface. After the rack had been 

 completed the employees were set to work on the bed of the river, 

 which was cleared of bowlders and snags and put in condition for fish- 

 ing. Live pens were made for retaining the salmon, and other work 

 preparatory to the fishing season was done. 



Fishing with gill nets began on the evening of September 22, and 

 on the following morning 43,000 eggs were taken from eight ripe 

 females. The run of fish gradually increased until October 15, when 

 194 were taken, 94 being females, and from these 412,000 eggs were 

 secured, making the largest single day's work of the season. By 

 November 8th 10,018,000 eggs had been collected, and as the capacity
