 row. — May 26. Reached Fort Enterprise May 31. Common on the 

 Barren Grounds one and a half days travel beyond the Coppermine River. 

 Song: like the first two notes of a White-throated Sparrow's. If a White- 

 throat's song is written sow-wheat, peabody, peabody, peabody, this bird's 

 song would be written sow-wheat, sow-wheat. The Indians recognized this 

 song as belonging to a small bird with a striped head.

The accompanying map is partly from the pubhshed maps of 

 the Interior Department of the Dominion of Canada. Great 

 Slave Lake north of Yellow Knife Bay and Lake Marion are so 

 inaccurately drawn there, that I give them from my own courses 

 and estimated distances. Aiejean Ti which is not shown on any 

 published map, I have mapped from my own observations. Diri 

 Ti, Jjamba Ti and Conghia Ti I have copied from a sketch map 

 made by Germain, an old Indian who has hunted this region all 

 his life. Winter Lake is double as I have drawn it. Canadian 

 maps show only the western end of the lower lake.
