THE PRINCIPAL LOCALITIES ABOUT CHICAGO FOR THE STUDY 

 OF PLANT SOCIETIES. 



In the following list of localities it will be convenient to discuss 

 the various districts about Chicago in regular order from north around 

 to southeast, using the various railroads^ and suburban street-car lines 

 as bases for discussion. The figures in parentheses after the various 

 towns indicate the railway mileage from the Chicago terminal station 

 of the particular railroad involved. References to pages are inserted, 

 showing where the various plant societies mentioned are described in 

 the body of the text. The accompanying maps show the geographic 

 and physiographic features of the places mentioned. 



A number of the interesting localities about Chicago, as indicated 

 below, can be reached at small expense by utilizing the suburban 

 street-car lines. From the standpoint of expense, and often of con- 

 venience, though not of time, the street-car lines are perhaps the best 

 means of transportation for the points which they reach. However, 

 some of the railroads, notably the Illinois Central and the Chicago 

 Terminal Transfer, sell suburban tickets for but slightly more than 

 street-car rates. Most of the railroads sell cheap ten and twenty-five 

 ride tickets, good for bearer, to the various points named below. These 

 tickets are usually good for one year from date of sale, though on the 

 Michigan Central and Lake Shore and Michigan Southern railways 

 these tickets are good for but one month. On some railroads, especially 

 the Wabash, Chicago and Eastern Illinois, and Chicago, Rock Island 

 and Pacific, the above-named tichets are good until used.' All of the 

 railroads make rates for parties of sufficient size. 



The places that can be reached by street-cars are briefly mentioned 

 in connection with the various railroads, but it may be well to- make a 

 generalstatement about the suburban street-car system of Chicago and 

 vicinity. The EvanstDn street-car line passes near the dune, beach, 

 and swamp region about Edgewater. ' (See C, M. & St. P. below.) 

 The Chicago, Waukegan and Milwaukee car line reaches all the 

 districts along the north shore, as described on the line of the C. & 

 N. W. railway. The suburban service northwest is not good. Oak
