ests, especially in association with the east branch of Dupage river. 

 The places mentioned in this paragraph, except Elmhurst and Glen 

 Ellyn, can be reached by street-cars. 



The Chicago Great Western railway passes through essentially 

 the same territory as the Chicago and Northwestern. The Oak Park 

 spit is crossed at Forest Home (lo), and the natural vegetation shows 

 fairly well at this point (p. 64). The Desplaines river is crossed 

 between Forest Home and Maywood, but the flood plain vegetation has 

 been somewhat altered by artificial agencies. The morainic country 

 west of Maywood {iz) is largely tilled. The Illinois Central railroad, 

 Omaha line, also passes through the country just described. Interest- 

 ing studies of the first vegetation on clay soil (p. 48) can be made along 

 the drainage canal at Lawndale Ave. (7), Crawford Ave . (8), or Hyman 

 Ave. (g); this part of the canal can also be reached by the street-car 

 lines. The Calumet beach, which shows the usual oak vegetation (p. 64), 

 is crossed at Parkway Ave. (12). At North Riverside (13) the Des- 

 plaines is crossed and a good flood plain forest can be observed (p. 25). 

 At itillside (17) there is a limestone cut, a rare feature about Chicago; 

 rock vegetation (p. 44) can be finely studied here. From Addison (24) 

 the forests along Salt creek, referred to in the preceding paragraph, 

 can be easily reached. 



The Chicago, Burlington and Quincy railroad passes through a 

 country of much interest. Extensive prairies are seen from Chicago 

 to Riverside (11); at this latter place is a splendid field for study, the 

 bottoms of the Desplaines river being covered with a luxuriant flood 

 plain forest (p. 25). On the east bank of the river the Calumet beach 

 (p. 64) and the xerophytic river banks (p. 18) show the usual features. 

 At ififlrf G^r^w^/a/^ (12) the Salt creek flood plains may be seen; this 

 stream empties into the Desplaines about half a mile from the station- 

 Between Western Springs (15) a.ndJfinsdale (17) is an excellent region 

 for study; the headwaters of Flag creek are in a rather poorly drained 

 swamp (p. 35); west of this is a typical morainic topography with con- 

 siderable areas of forest (p. 47). North of Hinsdale there are also 

 morainic forests and a number of interesting places along Salt creek. 

 Morainic forests with maples as well as oaks may be seen at Dow- 

 ner's Grove (21). There are forests along the branches of the Dupage 

 river at Lisle (24) and Nafierville {2%).
