4 Introduction to Botany. 



The student should never ask the teacher questions 

 which with reasonable effort he can answer for himself ; 

 as questions arise, he should continually recur to the sub- 

 ject of his study as the most reliable source of information 

 about itself. 



It is a good plan, when pertinent questions are asked, 

 to write them on the blackboard for the class to consider, 

 and finally to use them as topics for a general discussion. 



4. Field Work. — The laboratory work should, of course, 

 be supplemented by field work. The locality where the 

 work is to be carried on should first be visited in order to 

 determine what the students can best learn there ; then 

 questions and directions should be written on the black- 

 board for the student to copy, in order that his work may 

 have definiteness and meaning. Drawings and notes 

 which are to count as an essential part of the course 

 should be required in this work. In succeeding chapters, 

 problems are given which are to be worked out in the field, 

 but they will need to be supplemented by others particu- 

 larly adapted to the specific locality.
