1883.] On the Circumpolar Expedition to Fort Rae. 179 



At Winnipeg I remained a couple of days to adjust accounts with 

 the Hudson's Bay Company, and on the 4th November we started for 

 Quebec, going by rail via Chicago. We reached Quebec on the 8th, 

 and Liverpool on the 20th November. 



In conclusion, I have to acknowledge the assistance received from 

 the officers of the Hudson's Bay Company, who spared no trouble in 

 carrying out my wishes, especially Chief Commissioner Grahame at 

 Winnipeg, Chief Factors MacFarlane and Camsell, in charge of the 

 Athabasca and Mackenzie Risrer Districts respectively, and Mr. King 

 in charge at Fort Rae. To their hearty co-operation the success of 

 the expedition is in great part due.
