METHODS OF STUDY. 6 I 



bark, branches, leaves, as well as flowers and 

 fruits. Take a single tree, e. g., the hickory, for 

 special investigation ; collect and study its buds, 

 branches, bark, wood, leaves, flowers, nuts, seed- 

 lings, saplings, etc. Learn the uses of forests, 

 their relations to rivers, winds, frosts, rain; their 

 help to civilization, the desirability of trees and 

 parks in cities. 



XI. Fruits and seeds; color, form, structure, modes of 

 attachment ; make sections and draw. Study the 

 distribution of plants, the agencies concerned (such 

 as insects, birds, squirrels, other animals, wind, 

 rivers, etc.) ; see how man voluntarily and other- 

 wise aids in this process. Note the various adap- 

 tations in fruits, seeds, or in the whole plant to 

 further dissemination. 



XII. Color in plants. 



(1) Of flowers ; note whether the seasons have par- 

 ticularly prominent colors ; whether the colors 

 have any relation to insects ; make lists of white 

 flowers, of red, yellow, blue, etc. 



(2) Of fruits ; aids to dispersion by birds, protec- 

 tive colors of green fruits, etc. 



(3) Of foliage ; relation to the season, light, shade, etc. 



XIII. Our native shrubs; collect and study the flowers 

 and fruits ; note their habitats. 



XIV. Make lists of spring flowers, summer flowers, etc., 

 or flowers of a certain month. Note the proces- 

 sion of flowers. 



XV. Study the odors of flowers ; make lists of fragrant 

 ones, note at what seasons they are found, and 

 their relation to the color, habitat, etc., of the 

 plant, and to insects. 



XVI. Study the weeds of a locality, and try to learn, 

 why they are so common, how their seeds are car- 

 ried,* why they are troublesome or so difficult to
