traversed by only one ridge not over 200 feet high. The construction 

 of a tramway would establish an easy line of communication between 

 the lake and salt water. 



KLAWAK. 



This station is located near the west coast of Prince of Wales 

 Island on Klawak Lake, about 6 miles from the village of Klawak. 

 It is operated jointly by the North Pacific Coast Trading & Packing 

 Co. and the North Alaska Salmon Co. 



During the period from August 6 to October 17, 1910, a take of 

 6,786,500 red salmon eggs was made, from wliich 6,200,000 fry were 

 planted, beginning in November and continuing into April, 1911. 

 This shows a loss of 586,500 or between 8 and 9 per cent. During the 

 fall of 1911 the total collection of redfish eggs at this point numbered 

 5,600,000. These figures are based upon a reckoning at the rate of 

 3,500 per female, but hereafter the quantity of eggs wiU be actually 

 measured. 



The new hatching building erected in 1908 is a substantial single- 

 story structure 24 by 85 feet in size, 12 feet at one end of wliich is 

 cut off for living quarters. The building is neatly ceiled \ip both 

 inside and outside with matched lumber and is well lighted. It is 

 heated by means of large stoves; overhead is a loft for storage pur- 

 poses. The head of the water-supply system is at a dam 2,000 feet 

 from the hatchery. The water is conducted in an almost straight 

 line by means of 1,400 feet of covered flume and 600 feet of wooden 

 pipe. A fall of 16 feet in this distance insures an excellent flow. The 

 water is unusually clear and carries very little sediment. 



In the hatchery there are 20 troughs set crosswise of the building, 

 and at 6 baskets to the trough the present maximum capacity is 

 about 8,000,000 red-salmon eggs. There is room, if necessary, to set 

 up several additional troughs and increase the capacity to about 

 10,000,000. Heretofore eggs have been taken by the method of hand 

 expression, but henceforth the improved method of incision will be 

 employed. The fry are put in buckets and taken to various suitable 

 planting grounds, care being exercised to avoid the mouths of creeks 

 where trout congregate. 



The crew consists ordinarily of three persons who are engaged 

 most of the year. Although small, the Klawak station classes with 

 the best in Alaska. 



HETTA. 



This hatchery is located near the southern end of Prince of Wales 

 Island. From the 9,141,000 redfish eggs taken during the period from 

 August 16 to December 18, 1910, plants of 8,552,500 fry were made, 

 beginning on December 27, 1910, and extending into July, 1911. 

 The loss during the period of incubation was less than 6^ per cent.
