A FIELD TRIP FOR ECOLOGICAL STUDIES OF 
PLANTS. 
As far as possible it is a very desirable feature of plant study 
to go to the place where the plant lives, and observe the sur- 
rounding conditions of moisture, soil, light, and other plant 
forms, in this way becoming acquainted with the plant as a 
definite living thing, requiring a certain environment in order 
to most fully accomplish its life work. 
Even in large cities it is possible to do some of this field 
work, and the result of this form of study will amply repay 
the time necessary. Where access to the country is at all 
practicable, much benefit may confidently be expected from 
this form of plant investigation. 
In order that the method may be fully understood, an out- 
line is presented below of an actually existing (May, 1900) 
field for study in the city of Chicago. The student is expected 
to go over the course laid out, provided with a definite route 
and a note-book, and is to report upon the observations made 
during some stated time. 
A FIELD TRIP TO BOWMANVILLE.

study the small woodland on the right side. What trees are 
found? What herbs? At the north margin observe particu-
