and sedges, and, in some localities along the brook, cat-tails and rushes. 

 Numerous moss-covered logs and hummocks rise from the standing water 

 or from the soggy earth. Around the edge of the swamp and along the 

 wood roads there are also dense tangles and thickets of weeds and shrub- 

 bery and near the southern end, an expanse of damp meadow. The altitude 

 of the swamp is 880 feet and it is surrounded by hills rising to a height 

 of 1000 to 1200 feet. The estimated average summer temperature during 

 the six hottest weeks is about 69 degrees F. The birds included in this 

 list are from the records of Burtch and Stone, the number after each species 

 representing its relative abundance as compared with the Song sparrow, 

 which is held to be the most abundant bird in the swamp and is marked 

 100. In addition to those birds which 'nest within the swamp, the author 

 has added from his own observation and consultation with Messrs Burtch 

 and Stone the following species which nest within half a mile, but their 

 relative abundance can not be determined: Killdeer, Belted kingfisher, 

 Chimney swift, Prairie horned lark, Vesper sparrow. Savannah sparrow. 

 Grasshopper sparrow, Chipping sparrow, Field sparrow. Cliff swallow. 

 Barn swallow. House wren and Ring-necked pheasant.
