PREFACE 



This manual contains the exercises that have been given in 

 connection with the work in General Horticulture at the Ohio 

 State University, Michigan Agricultural College, and University 

 of Nebraska. 



It is a modest attempt to fill a place that, for a long time, has 

 seemed to be vacant. The aim is to give the student an outline 

 by which he can better grasp some of the fundamental princi- 

 ples of horticulture, and an opportunity to learn by actual ex- 

 perimentation and observation the reasons for certain necessary 

 operations in horticulture. 



It is the object of this manual to give explicit directions for 

 every detail of the work. In certain exercises it may be impos- 

 sible for the student to do all the tasks outlined, but only such 

 parts as are suited to the conditions under which the student is 

 working should be attempted. This must be determined by the 

 instructor, who, it is hoped, will select those exercises that are 

 most practicable for his class. 



The drawings asked for and the questions raised in the sev- 

 eral exercises are designed to bring out fundamental principles 

 and important points as well as to fix firmly in the mind of the 

 student the necessity of careful and systematic work. 



The author has made use of suggestions found in other works, 

 and has endeavored to bring together the information that will 

 be the most helpful to the student, and to present it in such a 

 manner that it will be of value to the beginner. He makes no 

 claim of completeness for this outline : only such exercises have 

 been included as seem best adapted to a general course in horti- 

 culture. Most of these exercises can be done in the laboratory, but 

 after the fundamental principles have been thoroughly mastered 

 field practice should be given in pruning, spraying, etc. 



The exercises are arranged in groups which naturally fall 

 under a common head. It is not likely that the instructor can 

 begin with the first exercise and continue uninterruptedly to the
