1922] Swarth: Birds and Mammals of the Stikine Region 141 



Sergief Island is the home of Mr. W. B. Parrott, who has cleared 

 a small tract of land and for some years has successfully raised garden - 

 vegetables and ginseng. We established our camp in a cabin in the 

 woods about a mile from his place. Prom Sergief Island, Dixon, in 

 company with Mr. Parrott, made a four days' trip to Blind Slough, 

 Mitkof Island, ten or twelve miles to the westward.

Fig. M. Sand flat at eastern end of Sergief Island, Alaska. On that side 

 of the island, deposition of sediment from the Stikine has resulted in the build- 

 ing up of a strip of sandy soil that now lies above the level of the highest stage 

 of river or tide. This strip is grown up with tall grass and pea vines. At the 

 landward margin there are bordering thickets of alder and willow, and groves 

 of Cottonwood. Beyond, steep slopes arise, covered with spruce. The tall grass 

 was the haunt of the rusty song sparrows. The bordering thickets at the time 

 of our visit harbored numbers of migrants, such as the golden-crowned sparrow, 

 Oregon junco, lutescent and Townsend warblers, dwarf hermit thrush, north- 

 western robin, and varied thrush. Photograph taken August 20, 1919. 



TOPOGEAPHY OP THE REGION AND ITS BEARING UPON 



ANIMAL LIPE 



The Stikine River rises in northern British Columbia east of the 

 Coast Range and flows southerly and westerly to the Pacific. Its head- 

 waters interlock with those of the Liard and with streams that flow into 

 the Yukon. Thus, the height of land that traverses northern British 

 Columbia serves as a divide between several great river systems. The 

 Liard flows northeastward through the Rocky Mountains to the 

 Mackenzie, which flows into the Arctic Ocean ; the Yukon flows north-
