vegetation (p. 57), also old beach lines (p. 64), and dying swamps 

 (p. 3s). Along the Milwaukee division of the C, M. & St. P. railway, 

 there are good opportunities for the study of the river series along the 

 north branch of Chicago river. There is an excellent flood plain 

 forest (p. 22) at Forest Glen (10), and from here to Oak Glen (16) 

 there are good river conditions, and also upland forests. Two miles 

 west of Deerfield [2/\,) there is an extensive forested country, oaks domi- 

 nating for the most part, but with many maples towards the Desplaines 

 river (p. 49). 



Northwest. — The Wisconsin Central railway runs rather close to ■ 

 the Desplaines river for many miles; studies of flood plain forests 

 (p. 25) may be made by walking about a mile east at Franklin Park 

 {1$), £>esplaines (23), Wheeling (30), and Prairie View (34). From 

 this latter point the splendid forests referred to in the preceding para- 

 graph can be reached as conveniently as from Deerfield. The ChicagI) 

 and Northwestern railway, Wisconsin division, crosses the Desplaines 

 river at Desplaines (17), at which point there is ^ fair place for flood 

 plain study. At Barrington (32) there are interesting morainic forests; 

 three miles northeast is Lake Zurich. 



The most interegting country northwest of the city is along the 

 Chicago, Milwaukee and St. Paul railway, Elgin line. At Gale- 

 wood (9) the Glenwood beach is very prominent, and a marked con- 

 trast is shown between the tree vegetation of the beach (p. 64), and the 

 prairie to the east (p. 42). West of Glendon Park (12), where the 

 railroad crosses Desplaines river, is one of the finest forest districts 

 near Chicago; the flood plain flora (p. 25) merges gradually into the 

 flora of the flat moraine (p. 48), with morainic swamps (p. 40). At 

 Woodale (it)) \!t\.e. railroad crosses Salt. creek; along this stream there 

 are upland forests (p. 47), as well as various phases of stream vegeta- 

 tion. There are extensive morainic forests with oaks and hickories 

 west of Bartlett (30). 



West. — The Chicago and Northwestern railway. Galena division, 

 passes through an extensive prairie district in the west part of Chicago, 

 now largely built up. The Calumet beach is crossed at Austin (7) and 

 the Oak Park spit at Oak Park (8), but the original oak vegetation has 

 largely been destroyed. At River Forest (10) an excellent flood plain 

 forest is still preserved (p. 25). Northwest of Elmhurst (16) there are 

 some morainic forests (p. 47), which grade into flood plain forests along 

 Salt creek. Near Glen Ellyn (22) there are interesting morainic for-
