on the L. S. & M. S. Railway (q. v.), and is a place of the greatest 

 botanical and physiographic interest. Between Porter and Michigan 

 City (56) the railroad crosses a peninsular portion of morainic terri- 

 tory and then follows somewhat closely the preseilt shore, affording a 

 splendid view of the dunes. 



The Baltimore and Ohio railroad passes through the same general 

 territory as the L. S. & M. S. Railway between Whiting (25) and 

 Miller (38); see above), but somewhat nearer the, lake. Dunes, both 

 living and dead, as well as swamps, can be seen at Edgemoor (30) and 

 Grand Calumet Heights (35). Beyond Miller this road passes through 

 a very interesting swamp region, including Cassandra and tamarack 

 swamps (p. 35); ancient dunes of the Tolleston and Calumet beaches 

 are also well displayed. 



The Wabash railway, Buffalo line, uses the same tracks as the C, I. 

 & L. Railway to Hammond {2.1); here, as well as sX East Chicago (22) 

 and Tolleston (29), the conditions are as noted above for the P. F. W. 

 & C. Railway. Aetna (33) corresponds to Miller on the L. S. & M. 

 S. Railway. Near Crocker (42) the various stream phases (p. 13) are well 

 illustrated along Salt creek.
