MEETING OF THE BIOLOGICAL CLUB. 
The Biological Club met in Orton Hall, Oct. 5; the program 
consisted of reports of work done by the different members 
during the summer. 
Mr. Mills reported that the Baum Village was divided into clans 
and stated that copper, obsidian and pottery had been discovered 
in the mound. Explorations at Kinnickinnick showed that the 
implements etc. used were the same as those in the Hopewell 
collection. The structure of this mound is somewhat peculiar: 
at its base is a low platform of hard tamped clay and below this 
is an older village site. He also reported the discovery of the 
skull and lower jaw of a mastadon at Grove City. They were 
imbedded in boulder clay about 9 feet below the surface. 
Prof. Osborne reported an increased attendance at the Lake 
Laboratory. His work was esp dally with the Henhptero. He 
reported that the attendance at the Zoological Section of the 
A. A. A. S. was large and the papers good. He mentioned 
especially some on the cicada which showed that it took food in 
its adult state and that there are according to measurements of 
specimens several distinct species previously supposed to be 
varieties. 
Prof. Prosser reported work on the Columbus quadrangle of 
the Topographical survey which showed some very interesting 
features and gave the results of some of his work on the correla- 
tion of various formations. 
Prof. Schaffner reported Elymus hirsutiglumis as new to the 
state list and gave some notes and photographs of the Ecology of 
the prairies, showing strikingly the effect of water. 
Miss Riddle reported finding some of the more unusual flower- 
ing plants at Sandusky and collecting numerous algae from the 
Bay. 
Dr. Killerman reported three weeks of very profitable collecting 
along the Greenbrier River in south-eastern West Virginia. He 
stated that his results were not ready for a full report as yet. 
Mr. Griggs gave some account of a trip to Guatumala, empha- 
sising the opportunities for investigation of tropical forms and 
the relative ease with which one could take advantage of them. 
A committee consisting of Prof. Osborne, Prof. Killerman and 
Miss Flynn was appointed to nominate officers for the ensuing 
year. 
Otto E. Jennings, 
Secretary, pro tern.
