Dec, 1913.] Meeting of Biological Club. 217 



In conclusion it might be stated that what is frequently taken 

 for the seed-coat in the cocklebur is really the wall of the achene 

 and quite different in structure from a true seed-coat. If past 

 experiments have correlated this pericarp with true seed-coats it 

 may be that further investigations might be of advantage. 



Summer in a Bog. Mrs. Katharine D. Sharp, of London, O., 

 has published an interesting little volume with the above title. In 

 the course of the narative many Ohio plants are mentioned with 

 some of their peculiarities, habits, and habitats. There are also 

 paragraphs on the women botanists of Ohio, short biographies on 

 Ohio botanists in general and on some of the great botanists of the 

 world. 



Altogether Mrs. Sharp has produced a readable book which will 

 no doubt, lead many a person into the woods and bogs to discover 

 some of the interesting plants enumerated, for themselves. If 

 this result is accomplished and even a few brought into direct con- 

 tact with nature the book will have performed its mission. There 

 is need for the city dwellers especially, who have mostly been 

 turned to the merry-go-round park and the Sunday picture 

 show, to return to the saner types of recreation.

Meeting of the Biological Club. 



Orton Hall, October 6, 1913. 



The first meeting of the year was called to order by the Pres- 

 ident, Mr. Stover, at 7:45 P. M. 



In the absence of the Secretary, Blanche McAvoy was appointed 

 Secretary pro tem. Reports of summer work were given. 



Prof. Osbom spent the first part of the summer at Lake 

 Lab. and the latter part collecting leaf hoppers in the State 

 of Maine for economic purposes. He collected 125 new species 

 for the State of Maine and extended the range for 30 species. 

 Prof. Lazenby spoke of the effect of light on certain introduced 

 species of trees, the Norway maple for instance. He also spoke 

 of the scarcity of flies during the summer, due to the precautions 

 used in the different neighborhoods. 



Prof. Schaffner told of his observations at Cedar Point. Weeds 

 and introduced species are more plentiful than they were a few 

 years ago. Prof. Schaffner found many ecological variations of 

 the sand bar willow, Salix interior. His state catalogue of 

 vascular plants has been finished. There are 2,065 species of
