the small station of Loxa. Along this track the telegraph-pole num- 

 bers were used in locating our substations. This is a rather level black 

 soil area, originally poorly drained and wet, but now considerably 

 modified by the ditching and grading occasioned by railway construc- 

 tion and maintenance. The changes have been similar to those on the 

 prairie north of Charleston, but the ditching has been a few feet deeper 

 and the embankment is higher. The most abundant and characteristic 

 kinds of vegetation are the tall prairie grasses — blue stem (Andropo- 

 gon furcatus), drop-seed (Sporobolus cryptandrus), and beard grass 

 (Andropogon virginicus) — a rosin-weed (Silphium laciniatum) , the 

 flowering spurge (Euphorbia corollata), wild lettuce (Loctuca can- 

 adensis), rattlesnake-master (Eryngiuin yuccifoliuni), and beggar- 

 ticks (Desmodium). Many other kinds of plants were also present. 

 The general appearance of this habitat is shown in plates VI and VII.
