12 SALMON FISHERIES OF ALASKA. 



ment, in connection with which the river fishes generally may be studied. Second, 

 the conditions, methods, and statistics of the salmon fisheries. Third, the artificial 

 propagation of the salmon in Alaskan rivers. 



Mr. Stone has been detailed to accompany you on account of his extensive knowl- 

 edge respecting salmon culture on the Pacific coast. He should be given special 

 charge of that branch of the work, but he will undoubtedly be able to assist you in 

 the other subjects. Otherwise you will apportion the work among your assistants in 

 such manner as seems best. 



The duration of your stay in Alaska will be determined by the length of the 

 season suitable for field investigations. A letter has been addressed to the Alaska 

 Commercial Company, requesting them to furnish you and your party with transpor- 

 tation to and from Alaska, and to grant you the customary facilities at their stations. 

 Tou will call at the office of the company immediately upon your arrival in San Fran- 

 cisco, and ascertain what arrangements can be made with them. 



Should the opportunities occur for sending mail home, you will inform me, from 

 time to time, of the progress of your work. 

 Very respectfully, 



M. McDonald, 



Commissioner.
