APPENDIX 



A SYLLABUS OF LABORATORY WORK 



The laboratory exercises here outlined have been used 

 by the author in his instructional work. 



Each student performs the exercises, so far as possible, 

 and the apparatus needed is provided. The student 

 should be required to write a description of the work 

 performed, stating results in every case, supplementing 

 his notes by drawings in special cases. 



It has not been found practicable to make the lecture 

 room and laboratory work fully correspond as to time, 

 but the effort has been made to do this as far as possible. 



A greenhouse is very desirable for this kind of instruc- 

 tion, and if the instruction is given in winter, a "garden 

 house," i. e., a glass house inclosing an unobstructed area 

 of garden soil is scarcely less important. But in the ab- 

 sence of these conveniences, a few window boxes will 

 furnish a tolerable substitute. 



When the exercises are carried out during winter, 

 considerable foresight is essential to have the needed 

 materials in condition for use at the proper time. 



To stimulate observation (1).* A few object lessons are 

 given to encourage observation and correct reasoning. 

 A twig, an ear of corn or a potato tuber is given to each 

 student and all are encouraged to vie with each other in 

 discovering new points, and in discussing the reasons 

 therefor. This lesson is frequently repeated during the 

 term. 



*The numbers in parenthesis refer to the paragraphs in the book.
