Manitoba was that if they happened to find a nest of this species contain- 

 ing eggs or young, either they themselves or a near relative would soon 

 die. Nothing would induce the Indians to search for nests of this species. 



Passerherbulus nelsoni nelsoni. Nelson's Sparrow. — This species 

 was found about midway up the west shore of Lake Winnipeg on July 11, 

 1914. No doubt it was breeding there. 



Penthestes hudsonicus hudsonicus. Hudsonian Chickadee. — As 

 there is only one record of this species for the Province, that of Macoun 

 for Porcupine Mountains, it may be well to state that I noted it at two 

 places on the west shore of Lake Winnipeg on July 17 (an immature bird) 

 and on September 6. I also noted it at Lake St. Martin on October 26, 

 1914. — Eric B. Dunlop, Winnipeg, Manitoba. 



Bird-Notes from Cambridge, Isanti County, Minnesota. — Isanti 

 county is situated in the southern part of east-central Minnesota, and is at 

 one point only eight miles distant from the St. Croix River — in this vicinity 

 the boundary between Minnesota and Wisconsin. Its northern boundary 

 is about thirty miles south and slightly southeast of Mille Lacs Lake, 

 which is midway between the northern and southern extremities of Minne- 

 sota. The size of the county is small compared with the others in this 

 state, its area being only 456 square miles. In shape it is practically a 

 square from which two townships placed north and south of each other 

 have been cut out from the northeast corner. The adjoining counties are: 

 Kanabec on the north, Mille Lacs and Sherburne on the west, Anoka on 

 the south, and Chisago on the east. 



The greater part of the county is drained by the Rum River and its 

 tributary streams which are all small brooks and brooklets issuing from 

 nearby lakes. Rum River rises in Mille Lacs Lake, flows southward 

 through Mille Lacs, Sherburne, Isanti and Anoka Counties and unites 

 with the Mississippi at Anoka. Entering Isanti County about five miles 

 south of the middle of the western boundary, it flows northeastward about 

 fifteen miles, turns abruptly southward and leaves the county about eight 

 miles east of the southwest corner. Cambridge is situated five miles south 

 of the vertex of the angle formed and is near the river. The course of 

 the river is winding as may be shown by the fact that (according to the 

 State Drainage Commission) there are fifty-two miles of river in this county. 

 Its fall is very slight, only eleven inches per mile, the altitude of the river 

 surface ranging from 891 to 939 feet. The river valley is bordered by side 

 hills ranging as high as sixty feet above the level of the river. These some- 

 times rise directly from the water's edge in the form of bluffs but usually are 

 farther in the background, giving space for ample meadows in which grace- 

 ful bayous or " ox-bows " delight the eye. However, the southeastern 

 projecting corner of the county and the extreme northeast and northwest 

 corners are drained by small tributaries of the St. Croix. There are 

 numerous lakes of varying size usually small, Green Lake, the largest one,
