MEETING OF THE BIOLOGICAL CLUB. 
Botanic-vl Hall, October 2 , 1906 . 
The Club was called to order by the President, Mr. Griggs. 
The minutes of the previous meeting were read and approved. 
The program of the evening consisted of reports of the sum¬ 
mer’s work by the members. Prof. Osborn reported on the 
work carried on at the Lake Laboratory. Especially the work of 
Prof. Rice on the bird fauna of the Point, and Prof. Walton on 
the Protozoa and Annelids. Prof. Schaffner spent his summer 
in Kansas working on the flora of that region. While at work 
there he noticed a case of mutation in Verbena stricta. The 
normal flowers of this Verbena are colored a purplish blue; but 
the mutants were a whitish pink, and were found covering an 
area of about one square mi'e, being mixed with the native blue 
form. Prof. Hine spent the greater part of the summer at the 
Gulf Biologic Station in the interest of the Crop Pest Commis¬ 
sion. He reported that as yet no remedy had been discovered 
for the Cotton Boll Weevil, as a result it is spreading rapidly east¬ 
ward and northward; and at last reports was within thirty miles 
of the Mississippi River. Prof. Ball reported that the Codling 
Moth and the Grasshopper cause a million dollars worth of dam¬ 
age annually in Utah. A Leaf Hopper that works on the sugar 
beet caused an estimated damage of seven hundred and fifty 
thousand dollars last year, while this year it caused practically 
no damage at all. Prof. Griggs reported on the fruiting habits 
of Bidens beckii, which he observed at Cedar Point. Bidens 
beekii which is an aquatic develops a seed provided with five 
barbed spines which are about an inch long. 
Prof. Osborn, Prof. Hine and Prof. Schaffner were appointed 
on a committee to nominate officers for the ensuing year. 
Prof. Osborn, Prof. Landacre and Mr. Metcalf were appointed 
on a committee to formulate a plan for entertaining the Ohio 
Academy of Science at its Thanksgiving Meeting in Columbus.
