Bulletin No. 27. 63 



The June census is not greatly in evidence in this issue, but would be 

 scarcely less appropriate for the next one. Let them come in. We shall 

 never know what our bird population is until we count at least a part of 

 it as a basis for estimates. If I did not feel that there was great need of 

 this sort of work noiu I would not urge it so persistently. If it could 

 be done even approximately for every section of every county of every 

 state of this whole country what a basis for future study and estimates 

 it would furnish ! Cannot we hope to accomplish some small part of 

 this this year i* It is not yet too late.
