84 NORTH AMERICAN FAUNA. [no. 27. 



Thelon, or Ark-i-linik, River, he reached its junction with the Du- 

 bawnt late in August and the foot of Baker Lake September 3. Hav- 

 ing obtained provisions and an outfit from a whaler, who had been 

 engaged to bring them in, and who was wintering at Depot 

 Island, he passed the winter with the Eskimo at the foot of Baker 

 Lake. He left here March 12, 1002, accompanied by a party of 

 Eskimo, and carrying canoes and provisions on dog sleds, reached 

 Ti-bi-elik Lake, an expansion of the Ark-i-linik a short distance above 

 its junction with the Dubawnt. Leaving here April 5, he struck on' 

 nearly due northward for the Arctic coast. Pelly Lake, on Back 

 River, was crossed April 14, and the Arctic coast near Ogden Bay 

 was reached May 14. From this point they proceeded westward 

 along the coast, still traveling with sleds. Canoe navigation was not 

 possible until July 12, when the party had reached a point 60 miles 

 east of the Coppermine, which they reached July 18. Ascending the 

 Coppermine and Kendall rivers, the height of land to the head of 

 Dease River was crossed and Great Bear Lake was reached August 

 10. Proceeding along the north shore of Great Bear Lake, the party 

 descended Bear River and reached Fort Norman August 30. A 

 detailed account of these journeys, published in 1004, contains many 

 notes on the fauna of this little-known region. 



In 1000 J. W. Tyrrell, of the Dominion Lands Survey, accompa- 

 nied by C. C. Fairchild and Archdeacon Lofthouse, made a journey 

 of exploration between Great Slave Lake and Chesterfield Inlet. 

 Reaching Fort Resolution April 1. by way of the winter trail from 

 Edmonton, they transported their supplies over the ice by means of 

 sleds to the eastern end of the lake, where they arrived May 0. 

 Thence they proceeded by way of ' Pike's Portage, 1 a succession of 

 small lakes and portages, to Artillery Lake. The head of this lake 

 was reached June 21. and from the southern extremity of Clinton- 

 Colden Lake, a short distance to the northward, they made a succes- 

 sion of portages through a chain of lakes over the height of land to 

 Hanbury River, a tributary of the Ark-i-linik, or Thelon. This 

 was descended to the junction of the two rivers, where they arrived 

 July 7. Then they descended the Thelon, finding it fairly well 

 wooded from a short distance below the confluence for about 170 

 miles, this isolated wooded area occurring well within the general 

 confines of the Barren Grounds. A short distance above the con- 

 fluence of the Thelon and Dubawnt the party divided. Fairchild 

 and Lofthouse proceeding to Hudson Bay by way of Aberdeen and 

 Baker lakes and Chesterfield Inlet, while Tyrrell retraced his course 

 up the Thelon and explored a considerable part of the course of 

 that stream above the mouth of the Hanbury. and a route acros- 

 country to Artillery Lake. The latter portion of the journey was 

 performed alone on foot by Tyrrell, while his voyagers returned
