56 JOURNAL OF ECONO.MIC EXTOMOLOGY [Vol. 4 



students in the four-year course of the College of Agriculture who 

 elect entomology as a part of a course in general agriculture and those 

 students in the College of Arts and Sciences who ■\\ash to take some 

 entomology but do not care to specialize in this subject. 



For these students we give a course consisting of two lectures per 

 week throughout the year and one laboratory period of two and one- 

 half hours each week during the first half-year. 



In this course the object is to give information by lectures and train- 

 ing in observation by laboratory work. The students in this class have 

 some foundation of biological knowledge, as a year's work in general 

 biology or a year's work in zoology is a prerequisite for admission to 

 the course. 



During the first half-year the lectures are on the characteristics of 

 the orders, suborders, and the more important famihes of insects, and 

 on the habits of representative species; the laboratory work includes 

 a study of the structure of insects and practice in their classification. 

 During the second half-year the subject is treated from the economic 

 standpoint. In the lectures the more important insect pests and 

 methods of controlling them are discussed; and at opportune times 

 the class is taken into the field to observe insect pests at work. It is 

 planned to expand this course by the addition of one period of two and 

 one-half hours per week of laboratory work in economic entomology, 

 which shall be taken in connection with the lectures of the second 

 half-year. 



It is obvious that in a course consisting so largely of lectures, the 

 imparting of information plays a more prominent part than does the 

 giving of scientific training. But the latter element is not lacking. 

 The lectures are so planned that the student in preparing for the 

 required examinations, which come at frequent intervals, must obtain 

 some conception of the foundation principles of the science. And in 

 the laboratory work, where the more general features of the structure 

 of insects, both external and internal, are studied, and where a large 

 number of specimens are classified, the student is given some training 

 in accurate observation. 



Third, regular students specializing in entomology. It is for this 

 class of students that the greater part of the work offered by the 

 department of entomology has been planned. All of our courses, with 

 the single exception of the course designed for the special stu- 

 dents, is open to them; the only restrictions being that certain ele- 

 mentary courses must be taken before advanced courses in the same 

 field can be elected, and a year's work either in general biology or in 

 zoology is a prerequisite for regular work in entomology. 



In all of the courses taken by this class of students, the imparting of
