MEETING OF BIOLOGICAL CLUB. 



Orton Hall, Dec. 4, 1911. 



The meeting was called to order by the President, W. M. 

 Barrows. The minutes were read and approved. The Club then 

 had the pleasure of listening to an interesting lecture by Prof. 

 Herbert Osbom on "Some Collecting Trips in Western States." 

 The trips of which Prof. Osbom spoke carried him through about 

 forty states and territories. Their principal object was the study 

 and collection of Jassidae affecting various forage crops. Certain 

 of these insects were found to be strikingly adapted to conditions 

 which must have prevailed for a long period of years. The talk 

 was illustrated with a number of excellent lantern slides and was 

 followed by an interesting discussion. 



The meeting closed after a short business session in which 

 Messrs. Schlopp, Mote, Busby and Bilsing were elected to mem- 

 bership. 



C. L. Metcalf, Secretary.
