rated into northern and southern subspecies. The western element 

 that appears in a few cases in western Tennessee here is entirely 

 lacking. But an additional factor is found in North Carolina in the 

 ecological influence of the coastal marshes where peculiar forms 

 appear. The extreme southeastern part of North Carolina is espe- 

 cially interesting, and it is suggested to observers that further studies 

 be made on Smith Island, which is related definitely to a more 

 southern region in its flora. As is ordinarily the case the informa- 

 tion here assembled is indicative for many species of the necessity for 

 further field work to determine the extent of their distribution. 



The friendly cooperation of J. D. Chalk, Commissioner of Game 

 and Inland Fisheries of the Department of Conservation and Devel- 

 opment, and of J. D. Findlay, of the same service, provided the 

 necessary permits under which this work was prosecuted. We are 

 also indebted to officials of the national forests lying within the State 

 for their aid. The universally friendly assistance accorded our field 

 party, particularly in the privilege of entering private lands, has been 

 most deeply appreciated. Without this courteous and interested help 

 the work could not have been prosecuted. 



The expenses of the party in the field were carried by the income 

 of the W. L. Abbott Fund of the Smithsonian Institution. 



So far as possible the itinerary was arranged to cover the different 

 sections of the State during both spring and fall, so as to obtain 

 representative material in both seasons. Necessarily the work in the 

 western mountains was done in the summer, as that is the most inter- 

 esting period for that region. In view of the extended observations 

 of naturalists for many years in the general vicinity of Asheville our 

 work in the mountains during 1939 was confined to the northern and 

 southern sections, which have been investigated little or not at all. 



Work in the field began on April 14, 1939, with Elizabeth City 

 as a base. The principal studies were made in the Dismal Swamp 

 area 7 miles west of South Mills, an old logging railroad and other 

 trails giving access to the swamp. Other work concerned a cypress 

 swamp near Gliden and higher lands of pines and old fields in the 

 vicinity of Sunbury and Weeksville. On April 28 the party trans- 

 ferred to Clinton in Sampson County. The spring migration then 

 had begun in full force, and here many birds were found, particularly 

 in Great Cohaire Swamp and in the vicinity of Roseboro, near 

 Bearskin Swamp and Little Cohaire Swamp. On May 8 Perrygo 

 worked near Raleigh to secure certain birds wanted from that area. 



On May 9 the work was transferred to Brunswick County in the 

 extreme southeast, where the men were located at Southport. Here 

 on the Coastal Plain the land was level, with extensive growths of
