72 APPENDIX. 



(.16); Otherwise the vegetation between Englewood and Blue Island is 

 chiefly prairie. A branch line of this railroad passes through Beverly 

 Hills and Morgan Park, joining the main line again at Blue Island. 

 All along this branch there are line opportunities for the study of 

 morainic forests (p. 47), beach line forests, and prairies. At Beverly 

 Hills {12') there are interesting ravines (p. 13), and also a fairly well 

 developed flood plain (p. 22). All the points thus far mentioned in 

 this paragraph, except Beverly Hills, can be reached by street-cars. 

 Beyond Blue Island are low prairies. At Dupont (21) sharp transitions 

 are seen between the prairie, beach line, and morainic forest. At 

 Tinley Park (23) ^.xv& Mokena (30) are morainic forests (p 47). New 

 Lenox (34) is an excellent place for study, showing morainic forests of 

 the maple type as well as oak, and also fine flood plain forests along 

 Hickory creek. This railroad furnishes the most direct route to 

 Starved Rock, Utica (94); see pp. 15, 20, 24. 



South. — The Illinois Central railroad, main line south, crosses a 

 region of swampy prairie between Grand Crossing (9) and Burnside 

 (12); at this latter place the Tolleston beach is crossed, showing the 

 typical vegetation (p. 64). Pullman (14) is perhaps the most convenient 

 point from which to study Lake Calumet, together with the swamp and 

 prairie derived therefrom (p. 33). At Riverdale (17) the Little Calumet 

 river, which shows flood plain forests (p. 2 2) and xerophy tic bluffs (p. 1 8), 

 is crossed, as is also the Tolleston beach for the second time. At 

 North Harvey (19) the river is again crossed. In the neighborhood of 

 Harvey (20) are extensive prairies. Between Hazel Crest (22) and Home- 

 wood (23) the Calumet and Glenwood beaches are crossed, showing 

 very interesting conditions, especially east of Homewood; ancient 

 dunes of considerable size and dying peat bogs (p. 39) are found in 

 profusion. South of Flossmoor (25) morainic (p. 47) and flood plain 

 forests are well shown along B^tterfield creek. The Blue Island 

 branch of the 1. C. R. R. passes through West Pullman (17), where 

 are to be found splendid illustrations of beach line vegetation, and 

 also undrained swamps; about a mile to the south is the Little Calumet 

 river, with a well developed flood plain forest. The South Chicago 

 branch of this railroad crosses numerous recent beach lines, and at 

 Cheltenham (11) runs close to the lake shore, where a recent beach and 

 dune flora (p. 56), and also the vegetation of a rocky shore, may be 

 studied. All the places named in this paragraph can be reached by 

 street-cars, except Riverdale, Hazel Crest, Homewood, and Flossmoor.
