the. winter in the United States. Mr. Edwards says that he does not 

 think it occurs in southern Louisiana in winter proper, unless perhaps 

 during protracted periods of warm weather, which sometimes occur in 

 December. Most other writers say decidedly that all leave the United 

 States in cold weather. Certain it is that none remained in the Mis- 

 sissippi Valley in the winter of 1883-'84. They crossed our border the 

 last week in February, but seem to have been few and scattered. The 

 first was noted at Water Valley, Miss., March 1, and March 5 a few 

 were seen at Gainesville, Tex., and Caddo, Ind. Ter., but no more fol- 

 lowed for some clays, and on this date they were marked at Abbeville, 

 La., as still remaining in the same numbers as when they arrived ten days 

 before. March 9 the first male appeared at Rodney, Miss., and was 

 followed ten days later by the first female. By March 11, they returned 

 to Caddo, Ind. Ter. ; were seen at Newport, Ark., and also at Waverly, 

 Miss. Still, all these were merely scouts, and it was not until March 

 13 and March 11 that the species become common in the Gulf States. 

 On these days they were marked as numerous at Eagle Pass, Tex., and 

 as arriving more plentifully at Abbeville, La., and beginning to sing a 

 little. March 21 this regular advance moved to southern Missouri, at 

 latitude 36° 56' and latitude 37° OS 7 , and March 24 to Saint Louis. The 

 next day it was noticed at Griggsville, 111., and Manhattan, Kans. 

 March 26, more came to Manhattan, and on the same date it was 

 reported from latitude 39° 09' and latitude 39° 14', in Missouri, and 

 an irregular scout moved to Tampico, III. (lat. 41° 36'). March 30 

 and April 1 a small company invaded southeastern Iowa, appearing 

 at four stations, and April 3 some of them even reached latitude 41° 42', 

 in Iowa, and latitude 43° 43', in Minnesota, but this was their last effort 

 before the April storms drove them southward. We find no records from 

 April 3 to April 10. On this latter date they began moving northward, 

 being seen at places in the rear of the position of the van of April 1. 

 About April 14 the advance was fairly under way and had proceeded 

 northward through the rest of Iowa to latitude 43° 43' in southern Min- 

 nesota, and through northern Illinois to latitude 43° 06' in Wisconsin, 

 with a scout north in Wisconsin to latitude 41° 30'. April 16 marked 

 an advance to latitude 44° 20', in Minnesota; April 17 to latitude 44° 

 32' and latitude 45°; and April 18 to latitude 45° 25'. Then came a 

 long pause, and it was not until after May 1 that any more movements 

 were recorded. May 3 the species appeared at latitude 46° 33' in Min- 

 nesota, and latitude 47° 52' in Dakota, though it is probable that the 

 former of these dates is later than the normal. May 19 they were seen 

 at Portage La Prairie, Manitoba, and May 23 at Oak Point, Manitoba. 

 Mr. Small, the observer at Oak Point, says that they were the first he 

 ever saw there. It is probable that in the line of migration from New 

 Orleans to Lake Wiunepeg almost the entire migration tot k place dur- 

 ing the following twelve nights: March 10, 20, 25, 27; April 11, 12, 13, 17; 

 May 3, 9, 17, and 19. The distance is 1,440 miles, hence the average
