REPORT OF THE PROFESSOR OF ZOOLOGY. XXXT 



COLLEGE WOKK OTHEE THAN INSTRUCTION. 



During the year I have given one of the regular Wednesday Lectures, sub- 

 ject Louis Agassiz. I attended the St. Louis and Quincy Institutes, at each 

 of Tvhich I gave two lectures. One upon Geology the other upon Economic 

 Entomology. During the year I have prepared three Bulletins, all of which 

 have appeared in the Report of the Board. 



During the entire year I have taught a large and interesting class in the 

 College Sabbath School. The subject of study was the Life of Christ. 



EXPEEIMENTS. 



The usual number of inquiries have been sent to the Department. Often a 

 single mail brings several such letters of inquiry. Such letters often require 

 no little investigiition which is always granted, and the desired replies given at 

 the earliest possible moment. Thus the Department does the extra work of a 

 State Entomologist. The present season we have carried on an extended 

 series of experiments already mentioned. 



THE APIARY. 



We have made no experiments in the apiary the past season, except to try 

 the "New Heddon Hive," and the solar wax extractor, with both of which we 

 are well pleased. We have increased our bees from twelve to thirty-nine 

 colonies and have sold quite an amount of honey. The season has proven that 

 drouth alone does not surely prevent the secretion of nectar by the flowers. 

 We have now so large an apiary that it is utterly impossible .to manage it well 

 with no other than student labor. Several colonies of bees have been sold 

 during the year. 



OUTSIDE WORK. 



Early in the winter vacation I prpared a paper on the " Relation of pollen 

 to the wintering problem, " which I read before the North American Bee 

 Keepers' Association at Detroit. I also prepared a monograph on " Insects 

 Injurious to Forage Plants " for Dr. Beal's new book on Grasses. I also re- 

 vised my Manual of the Apiary, the 14th, 1,000 of which was issued in May. 

 During the year I have lectured before two large Farmers' Clubs, upon 

 " Injurious Insects, " once at Deerfield and once at Volinia.
