be secured more economically at other points, they were abaudoued at 

 the close of the year. 



Clackamas Station, Oregon (W. F. Hubbard, Superintendent). 



Arrangements were made to operate (in connection with Clackamas 

 Station) substations on the Salmon and Little White Salmon rivers; 

 also a hatchery belonging to the Columbia River Packers' Propagating 

 Companj^ on the headwaters of Clackamas River; and with Mr. R. D. 

 Hume on Rogue River. 



The rack across the Clackamas was finished early in July. Hereto- 

 fore it had been constructed on a shallow riffle a short distance above 

 the station, but this season the property-owuers controlling the shores 

 objected, and it became necessary to locate it directly opposite the 

 station in much deeper water. During the summer the hatchery was 

 overhauled and placed in thorough repair, new foundations, sills, and 

 flooring being laid; many old troughs, which had been used since the 

 establi.sliment of the station, were replaced by new ones. The hatchery 

 was further improved by putting in new skylights. The water supply, 

 which had been very unsatisfactory in the past, was increased. 



Early in September, all repairs and preparatory work having been 

 completed, operations were commenced, but no ripe fish were taken until 

 September 15. The fishing below tlie rack was continued every night, 

 but very few fish were taken and only 380,650 eggs were collected in 

 September. As the prosj)ects for large collections in the vicinity of the 

 station were poor, arrangements were made early in October, with Mr. 

 G. H. Oldenburg, for collecting eggs at a point about 4 miles below the 

 station, at the rate of 40 cents per 1,000, eyed; and 821,800 were secured 

 from this source between October 20 and December 3, the eggs being 

 delivered in good condition. 



Fishing operations continued until October 21, when the water in the 

 river rose so high that the men were compelled to stop work. They 

 resumed on November 7, but by this time all the salmon in the vicinity 

 of the rack had spawned. As a result of the season's work, 1,072,275 

 eggs were taken from the Clackamas River. 



During September 1,006,000 eggs were received from Salmon River, 

 and commenced hatching on the 10th. The fry from the first lot were 

 not as strong as usual, which was attributed to the fact that the water 

 at Clackamas Station, taken from Clear Creek, is between 10° and 15'^ 

 warmer than that of Salmon River. As soon as the temperature fell 

 there was no difference between the fry hatched from eggs collected on 

 the Salmon and those on the Clackamas. Between October 10th and 

 November 10th, 4,000,000 eggs were transferred from the Little White 

 Salmon in four shipments, and on January 18 another consignment of 

 3,000,000 arrived from Battle Creek. These were in excellent condition, 

 only 2,200 being lost in transit. Plants of fry were made from time to 

 time, commencing October 7, in Clackamas River and Clear Creek, the 

 last plant being made on April 28. As a result of the eggs collected at
