Dear Dr. Petry: 
In 1913 the Botanical Society of America and the Brooklyn 
3otanic Garden entered into a cooperative agreement for the edit- 
ing and publishing of a research journal, the American Journal of 
Botany. 
I believe that this Journal, now in its 22nd volume, has the 
largest circulation of any journal devoted exclusively to botanical 
research, with the possible exception of governmental publications. 
As a result of this, the published research of members of the 
Botanical Society reaches a larger number of readers than would 
be the case with almost any other similar periodical. The mailing 
list includes the principal botanical institutions of research and 
higher education in 53 countries. 
What the members of the Botanical Society think of the ad- 
vantage of the Journal as a medium for the publication of research 
is reflected in the fact that the editor now has in hand accepted 
manuscripts sufficient to fill nearly two volumes of the present 
average Size.
