only eighteen miles a day. The average of five years' 

 records of arrival at Terry, Mont., is March 23, a date 

 about ten days earlier than that at which the species 

 appears in the same latitude in Minnesota. Its winter 

 home on the Pacific coast extends 1,500 miles farther 

 north than on the Atlantic, and hence it is not surprising 

 that the bird has been seen on the middle Yukon by May 

 3 and at the mouth of the Yukon by May 10. 



South of the breeding range the last green-winged teal 

 was seen at Raleigh, N. C, April 13, 1900; Hester, La., 

 April 6, 1902 ; northern Texas, April 16, 1886. The aver- 

 age date of disappearance for eight years at Keokuk, la., 

 is April 7, latest, April 30, 1892. 



Eggs were taken at Nulato, Alaska, latitude 65, May 

 20, and no earlier date seems to be recorded for the 

 regions to the south. Eggs have been found at Ed- 

 monton, Alberta, latitude 54, May 27, and in southern 

 Ontario, latitude 45, May 22. Downy young were seen 

 in the Devils Lake region of North Dakota June 20. 



Fall Migration. An average date for the reappearance 

 of the green-winged teal at Erie, Pa., is Sept. 15 (earliest, 

 Sept. 1, 1894) ; at Alexandria, Va., Sept. 29 (earliest, 

 Sept. 22) ; but it is not considered common until early 

 November. Corresponding dates of arrival are : Keokuk, 

 la., Sept. 21; central Kansas, Sept. 12; central Texas, 

 Sept. 22; central California, Sept. 17. The last was 

 noted on Prince Edward Island, Nov. 4, 1890; Montreal, 

 Can., Nov. 1, 1893; Aweme, Man., Oct. 30, 1896; Kowak 

 River, Alaska, Sept. 3, 1898; St. Michael, Alaska, the 

 first week in October: The average date of the last seen 

 in southern Ontario (thirteen years) is Oct. 28 (latest,
