of the month. May 19 they reached Portage la Prairie in Man- 

 itoba. East of the Mississippi Valley they were seen in Jessa- 

 mine County, Kentucky, March iS; at Buffalo, West Virginia, 

 March 22 ; Camden, Indiana, March 2S ; New Lexington, Pa., 

 April 16; Columbus, Ohio, April 15; Niagara Falls, April iS ; 

 Auburn, New York, April 20; Belleville, Ontario, April 22; 

 Ottawa, Canada, April 27. In New England the returns show 

 them at Saybrook, Conn., April 19; Greenfield, Mass., April 

 27 ; Moosehead Lake, Maine, April 23. They were seen at St. 

 John's, New Brunswick, May 2; Chatham, N. B. (Mirimichi 

 Bay, facing the Gulf of St. Lawrence), May 10; and at Cape 

 Breton Island, north of Nova Scotia, June 1. 



Turning now to the other side of the Continent, their 

 progress is found to have been much affected by the unfavorable 

 weather. In California Mr. L. Belding has records from San 

 Diego, April 28; Stockton, March 1; Marysville, March 17; 

 Poway, May 1 ; San Jose, May 3 ; Olema, May 8 ; and Chico, 

 May 22. 



Migration of the Baltimore Oriole {Icterus gallmla) 

 in the Mississippi Valley During the Spring of 18S4. 



By W. W. Cooke. 



The first record we have of this species is April 7, when it 

 appeared at Rodney, Mississippi, latitude 3i°52'; and the last, 

 May 25. at Oak Point, Manitoba, latitude 50 30'. This would 

 muke an average speed of twenty-seven miles a day. As we 

 found last year that the Oriole was a bird of quite uniform speed, 

 let us trace the record this year and see how it agrees. St. 

 Louis, Mo., latitude 38 40', is reached April 26, which would 

 be at the rate of twenty-five miles a day. but if we go directly 

 north we find a record on the 25th at Hillsborough, Illinois, 

 latitude 39 12', which would make a speed of just twenty-seven 

 miles a day. About April 29 and 30 there seems to have been 

 much movement of this species; not so much the advance of the 

 van as the filling up of the country already traversed, bringing 

 the bulk to the country from latitude 39 30' southward and the 

 van to latitude 41 , and in the west to Manhattan, Kansas, lati- 

 tude 39 12'. At twenty-seven miles a day they should have 

 advanced by May 6 to about latitude 43 30'. Now we have to 

 hunt for records of this advance. May 5 and 6 are davs of
