In this study note should be made of the plants comprising each society ; 

 the plants predominating and thus giving character to the group. What 

 conditions of sun, shade and soil seem to be most favorable to the well- 

 being of each society?

 contrivances. 



4. Comparing and drawing : — 



(a) Cross-section of a young maple and a corn-stalk. 

 (6) The veining of the leaves of the above plants. 

 (c) The seed-leaves of a maple or an oak, and the seed-leaves of
