74 APPENDIX. 



Beyond Blue Island this road passes through Harvey (see I. C. R. R.), 

 and crosses Thorn creek (see C. & E. I. R. R.). At Oak Glen (28) the 

 Calumet beach shows ancient dunes with the usual vegetation (p. 62). 

 Beyond Maynard (31) are extensive swamps. At Griffith (36) are 

 beach lines, and at Ainsworth (45) and beyond this road passes through a 

 morainic country. 



The Pittsburg, Cincinnati, Chicago and St. Louis railway 

 (Pan Handle Route) traverses the prairie district west of Engle- 

 wood, crosses beach lines at Washington Heights (see C, R. I. 

 & P. Ry.), West Pullman and Riverdale (see I. C. R. R.), and 

 Dolton (see C. & E. I. R. R.). After crossing the Little Calumet 

 river the Calumet beach is quickly reached at Lansing (27; see 

 Oak Glen, C. & G. T. Ry.). Beyond Maynard (29) are swamps and 

 low prairies, and at Sehererville (34) are extremely interesting ancient 

 dunes connected with the Glenwood beach. Beyond this the country 

 is morainic. 



The Chicago and Erie railroad uses the the same tracks as the C. 

 L & L. as far as Hammond (21). Beyond Hammond, also, the same 

 features are to be seen as on the road just mentioned. The Calumet 

 beach is crossed at Highlands (26), and beach lines are well developed 

 at Griffith (29). 



The Pittsburg, Fort Wayne and Chicago (Pennsylvania) rail- 

 way. At Constance (11) are extensive prairies, showing the stages of 

 development (p. 42); Hog Island, with a small area of morainic swamp 

 forest (p. 40) is a short distance southwest. At Roby (15) Wolf lake 

 shows all stages of development between lake and prairie, as at Calu- 

 met lake (I. C. R. R.); there are also many beach lines with oaks in 

 this neighborhood (p. 64). Constance and Roby can also be reached 

 by street-cars. Between Whiting (17) and Hobart (34) this railroad 

 crosses a great number of swamps*and beach lines. Among the best 

 places for study are Clarke (24), where forested beach lines and 

 undrained swamps are finely shown; the Grand Calumet river is close 

 by, with a rich aquatic and marginal vegetation. The Tolleston beach 

 line is well displayed at Tolleston (27), and the Calumet beach may be 

 seen at Liverpool (31). A branch line of the P., F. W. & C. Ry. 

 passes through Hegewisch (18), from which place Wolf lake (see 

 above) and various beach lines can be studied. Hammond (22) and 

 East Chicago (23), also reached by street-cars, are the best places near 

 Chicago for studying the typical swamps and sandy ridges of the dune
