22 BIRDS OF OHIO. 
Sim. Most of the work in Erie and Huron counties has 
been without company. 
From the foregoing remarks it will be clear that a consid- 
erable portion of the state remains to be explored ornitho- 
logically, particularly in the south and west. Some per- 
sons with considerable leisure ought to be posted along our 
southern and western borders to watch for invasions of 
species from Kentucky and Indiana. I earnestly hope that 
the appearance of this catalogue will mark the beginning 
of an era of unusual activity in the study of the birds of our 
fair state.
