of whom, Mr. Sherff, is studying the plant ecology of the Skokie 

 region, while the other, Mr. Geo. D. Fuller, is making transpi- 

 ration studies in the Chicago area. Mr. Shelford has completed 

 his elaborate work on the animal ecology of that entire area, 

 and his paper is presently to be published by the Chicago Geo- 

 graphical Society. Mr. Baker has lately published a monograph 

 of the Limnaeidae of North America, which contains a large 

 amount of ecological material applying to that family of mol- 

 lusks in Illinois. Mr. Transeau has continued his studies on the 

 Algae of the Charleston region, and Mr. Hankinson has con- 

 tinued work on the aquatic animals of this region, with special 

 attention to the nesting habitats of fishes. 



The principal publications on the ecology of the state issued 

 since our last meeting, are six bulletins of the State Laboratory 

 of Natural History containing 441 pages of text and seventy 

 half-tone plates. The topics are the ecology of the Skokie Marsh 

 area, by Mr. Baker; a study of the mammals of Champaign 

 county, by F. E. Wood; two papers on the shrew-mole in Illi- 

 nois, by Mr. Wood and J. A. West; the vegetation of the inland 

 sand deposits of IlHnois, by H. A. Gleason; a report on forest 

 conditions in Illinois, by R. Clifford Hall and O. D. Ingall, and 

 two papers on our biological investigations on the Illinois river, 

 by S. A. Forbes.
