time equally between zoology and botany ; the forenoons were 

 accordingly given to the former, and the afternoons to the latter. 



In the department of zoology emphasis Avas given to the 

 lines of work most useful to teachers. Material collected on 

 excursions was used in various Avays. For correct methods of 

 dissection as well as a better knowledge of anatomical details 

 some work in dissection was done. Time Avas also given to 

 acquiring the best methods of preserA'ing specimens of A-arious 

 kinds of animals, as Hydra, Avorms of various groups, mollusks,. 

 Critstacca, insects, — both larval and mature, — and fishes. The 

 identification of annelid Avorms, insects, mollusks, and fishes 

 received due attention, and Avas aided by named collections be- 

 longing to the State Laboratory, and also by literature and by a 

 number of synoptic keys to these groups prepared by members 

 of the State Laboratory staff. As a result of this part of the 

 Avork, teachers Avere enabled to take home AA'ith them properly 

 preserved and named collections of various kinds of animals. 

 All persons not already familiar Avith the ordinary methods of 

 section-cutting and the making of permanent microscopic prep- 

 arations had practice in such work. 



The Avork in botany consisted of as thorough a study of the 

 aquatic and terrestrial flora of the surrounding region as the 

 time Avould alloAV. The algae of the Illinois Eiver and connected 

 Avaters Avere studied Avith special reference to their morphology 

 and reproduction. The relation betAveen land and Avater plants 

 both as to their differences in morphology and distribution Avas 

 observed and discussed on the field trips. 



The phanerogams of the vicinity Avere treated Avitli spec-ial 

 reference to their adaptation for protection and cross-fertiliza- 

 tion. Instruction in the methods of the collection and preser- 

 vation of herbarium material Avas given to those who desired it. 

 The systematic Avork on the higher plants Avas in the nature of 

 a study of the characteristics of orders from different representa- 

 tives rather than by folloAving an artificial key. 



General plant physiology Avas illustrated by demonstrations 

 Avith apparatus such as can be employed in laborat(n-ies of 

 limited ecjuipment. In the field special attention Avas ]niid to 

 the movements of plant parts as influenced by light, tempera- 

 ture, and progress in seed-develoiuuent. Time at the end of the
