SURVEY OF THE FERNS AND FERN ALLIES OF OHIO. 



Prof. L. S. Hopkins, of the Kent Normal School, Kent, Ohio, 

 is organizing a survey of the entire state in order to obtain 

 exact information about our Pteriodphytes and their geographi- 

 cal distribution. This work, if thoroughly done, will be of 

 great interest and value, not only in giving us an exact list of 

 the species, but adding information about the ecological and 

 agricultural areas of the state. It is to be hoped that all botanists 

 of Ohio and members of the Ohio Academy of Science will 

 co-operate with Prof. Hopkins, either by making collections 

 themselves or inducing some interested person to do so. In this 

 way it should be possible to have one or more collectors in 

 every county. The material should be sent directly to Prof. 

 Hopkins, who will make determinations of the species.
