WILD FLOWERS OF THE VICINITY 
Observe the wild flowers as they appear in early spring. Keep a 
record, as suggested below, which will include the name, the date 
of flowering, the habitat (the type of place in which the plant is 
found), and the marked characteristics of the plant. Among the 
characteristics noted should be the arrangement and form of the 
leaves, of the flowers, and of the fruits. When possible determine 
the nature of the underground parts. Find out what you can of 
the purposes and principles of the Wild Flower Preservation 
Society of America.

WEEDS OF LAWNS AND GARDENS OF THE VICINITY 
This exercise may be used in the late spring or in the early fall. 
(It may have been used as a part of Exercise No. 74.) 
Make a collection of specimens of all the weeds which you find on 
your lawn and another of those which you find in your garden. 
Identify each. Learn whether it is a native or an introduced plant. 
(See Gray, New Manual of Botany.) Why is it troublesome, 
how is it disseminated, and in what way can it be eradicated or 
kept in check?
