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 tvpes 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 tern. Reports of summer work were given. 
Prof. Osborn 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
