how be>!t to deal with each case, either by the use of insecticides or 

 other methods. Finally, each student is required to prepare a thesis 

 on some insect or group of insects pertaining to the business in which 

 he intends to engage. He is asked at the beginning of the year what 

 occupation he intends to follow after graduation, and is then advised 

 to prepare his thesis on those insects with which he will have most to 

 deal in the business he has selected. In the preparation of this thesis 

 the work is carried on in the most approved methods, so that he may 

 obtain the most scientific and at the same time practical knowledge of 

 the subject ; in fact, he is taught such methods of investigation that, 

 if new insect pests appear on his crops, he will know how to properly 

 investigate them and discover the best and cheapest methods for their 

 destruction. If this thesis when completed contains information of 

 public interest, whether of an economic character or otherwise, it is 

 published with whatever illustrations are necessary. 



This course is primarily for the student of agriculture or horti- 

 culture, but, when taken in connection with botany and chemistry, is 

 especially adapted to one wishing to fit himself as a teacher of science 

 in our public schools, or to one intending to study medicine — but in 

 this case his laboratory work would be devoted mainly to histology. 



GRADUATE ENTOMOLOGY. 



This department is now prepared for, and is receiving graduates 

 from this and other colleges who wish to continue the study of ento- 

 mology beyond what they were able to do in their undergraduate 

 course. These advanced studies will fit them for positions in the 

 experiment stations, or as State Entomologists, and also give them 

 most excellent training as teachers in our high schools and colleges. 



A three years' course leading to the degree of Doctor of 

 Philosophy, is in active operation, three subjects — botany, chemistry 

 and entomology, arranged as a major and two minors — being required. 

 In those cases where entomology is chosen as the major subject, the 

 course consists of lectures and laboratory work, some of the topics 

 treated being the following : — 



General morphology of insects : embryology ; life history and 

 transformations ; histology ; phylogeny and relation to other arthro- 

 pods ; hermaphroditism ; hybrids ; parthenogenesis ; paedogenesis ; 

 and heterogamy; colours — chemistry of colours in insects; luminosity; 

 deformities of insects ; variation ; duration of life. 



(Ecology of insects : dimorphisms ; polymorphisms ; mimicry ; 

 warning coloi'ation ; insect architecture ; fertilization of plants
