the same places; the spring molt was progressing rapidly and the 

 plu in age was assuming higher colors. April 15 there was no change. 

 April 17 birds in high dress arrived: April 18 they were noisy and. con- 

 spicuous. By April 25 the highly colored birds had departed; flocks 

 remained in plain dress and singing but little. The bulk continued 

 until May 11, when great numbers of young, mostly plain females, ar- 

 rived; song not often heard. May 12 the bulk departed : May 17 the 

 last was seen. 



The first movement northward, about February 24, did not extend 

 far. Auother began about March 10, when the first arrived at Fayette, 

 Mo.; on the following day a stray one reached Chicago. March 15 the 

 first arrived at Danville, 111., and about this time the numbers increased 

 at Saint Louis. 



A third movement, though not as extensive, began March 27, when 

 the first arrived at Polo, 111. April 9 the first was seen at Xewton, 

 Iowa. Two days later. April 11, the first arrived at Bed Wing, Minn. 

 April 25 the first and only ones seen in spring migration ^ere observed 

 at Manhattan, Kans. April 28 they appeared at Elk Eiver, Minn.; 

 April 30 at Tei million, Dak; and May 10 at Frazee City, Minn. At 

 Green Bay, Wis., the bulk arrived May 4. At Coralville, Iowa, the 

 bulk arrived April 29, and left May 7, and the last was seen May 15. 

 At Waukou, Iowa, more than a hundred miles farther north, the last 

 was seen May 17. At Lanesboro, Minu., the bulk arrived April 30 ; the 

 height of the season was from April 30 to May 12; the bulk passed 

 northward May 20 ; and the last one was seen May 25. 



Thus the last great movement of this species began about April 25, 

 and was at its height during the first week of May. The bulk reached 

 Minneapolis, Minn., May 1; Elk Eiver, Minn., and Vermillion, Dak., 

 May 3; and Frazee City, Minn., May 12. At Argusville, Dak., none 

 were seen in the spring of 1S84. 



The line of migration of this species seems to follow the two great 

 rivers, the Mississippi and Missouri, and the timber belts along them. 

 Observers in the prairie regious rarely see them. 



In the fall of 1884 the first White-throated Sparrow was seen at Elk 

 Biver, Minn., September 22, and the bulk arrived September 27; the 

 last was seen there October 5. At Mount Carmel, Mo., the first was 

 seen September 27, and the last October 28. The first was seen at 

 Gainesville, Tex., November 13. A party of four was found March 4, 

 18S5, in the lowlands of Illinois, opposite Saint Louis, Mo., where they 

 had probably wintered. Other individuals, which had possibly wintered 

 in the vicinity, were seen at Saint Louis March 10 and March 25, and 

 at Shawneetown, 111., March IS. 



In the spring of 1885 regular migration did not begin until the last 

 two days of March. The first White throated Sparrow arrived at 

 Paris, 111., April 8, and at Emporia, Kans., April 18. The three days 

 from April 20 to 22 were days of great movement, and the species was
