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 possi- 

 ble, and the apparatus needed is provided. The stu- 

 dent should be required to write a description of the 

 work performed, stating results in every case, supple- 

 menting his notes by drawings in special cases. 



It has not been found practicable to make the lecture 

 rocm and laboratory work fully correspond as to time, 

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



A greenhouse is very desirable for this kind of in- 

 struction, and if the instruction is given in winter, a 

 "garden house," i. e., a glass house inclosing an unob- 

 structed area of garden soil is scarcely less important. 

 But in the absence of these conveniences, a few win- 

 dow 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 reason- 

 ing. 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.
