82 NORTH AMERICAN FAUNA. [no. 27. 



He was accompanied by William Spreadborough, who, working un- 

 der the auspices of the Survey, devoted his time to ornithological field 

 work, this being the tenth summer spent by him in similar work in 

 various parts of Canada. His ornithological observations, together 

 with many notes secured by members of the Canadian Geological Sur- 

 vey during various surveying trips, are incorporated in the ' Catalogue 

 of Canadian Birds,' by John Macoun, the first part of which was 

 published in 1000. and which was completed in 1904. 



During the years 1896 to 1800 A.. J. Stone, working under the 

 auspices of the American Museum of Natural History, traversed a 

 considerable portion of northwestern North America, mainly en- 

 gaged in collecting the larger mammals and securing information 

 regarding their habits and ranges. For present purposes his itin- 

 erary from the time he left Hell Gate Canyon, on the Liard, about 

 150 miles above Fort Liard, with the breaking up of the ice in May, 

 1808, may be briefly considered. From here he descended the river 

 alone to Fort Liard. where he secured help, and. proceeding about 100 

 miles farther down, made a trip into the Nahanni Mountains, study- 

 ing the range of Ovis dalli. Returning to the river, he descended it t<> 

 its mouth, reaching Fort Simpson about the middle of June. He 

 then descended the Mackenzie to Fort Norman, and with a party of 

 Indians traveled westward into the Rocky Mountain range, where he 

 secured a hue series of Ovis dalli. Returning to Fort Norman, he 

 continued on down the Mackenzie and ascended the Peel to Fort Mc- 

 Pherson. In October he made a trip with dog sleds into the Rocky 

 Mountains to the westward. Returning to Fort McPherson, he trav- 

 ersed the Mackenzie delta and the Arctic coast to Plerschel Island 

 in November, returning to Fort McPherson in December. In March, 

 April, and May, 1899, he traveled eastward along the Arctic coast to 

 Cape Lyon and back, sledging a thousand miles and securing much 

 information regarding the larger mammals and geography of the 

 region. In July he crossed the Rocky Mountains to the Porcupine, 

 and descended it to the Yukon. 



In the summer of 1899 Dr. Robert Bell, of the Canadian Geological 

 Survey, assisted by his nephew, J. Macintosh Bell, who was in charge 

 of a separate party, explored the shore lines of the eastern part and 

 the Northern Arm of Great Slave Lake. Work was begun late in 

 July and completed in September. Doctor Bell left Fort Resolution 

 on September 13, leaving J. M. Bell to pass the winter there and to 

 make further explorations during the following season. 



In 1900 J. M. Bell left Fort Resolution, where he had passed the 

 winter, on April 11, and crossed Great Slave Lake on the ice to Fort 

 Providence. On the breaking up of the Mackenzie he descended the 

 river by steamer and canoe to Fort Norman. He left here about the 

 middle of June, accompanied by Charles Camsell, Charles Bunn, and
