1920 by cooperating with the Ecological Society of America in 
the establishment of the quarterly journal, Ecology. 
Genetics —In 1922 the Garden became the publisher of the bi- 
monthly journal, Genetics, in cooperation with the Editorial Board 
of that journal. 
These three periodicals all have a circulation throughout the 
scientific world, in all countries, the circulation of the American 
Journal of Botany being, so far as we can ascertain, the largest 
of any technical botanical journal. 
The publication of these serials, together with the Brooklyn 
Botanic Garden Contributions and the Memoirs of the Brooklyn 
Botanic Garden, has made the Garden one of the active centers of 
botanical publication. The location of this work at the Garden 
has also strengthened our other work and greatly extended our 
usefulness. 
On January 15, 1927, the Garden entered into an agreement 
with the AMERICAN FERN Society for cooperation in the busi- 
ness management of the American Fern Journal, the quarterly, 
official publication of that Society. This was in connection with 
the project of genetical studies of the Boston Fern (Nephrolepis), 
which have been carried on at the Garden since 1915 by Dr. Ralph 
C. Benedict, Editor of the Journal and Resident Investigator at 
the Garden since April 1916. (See p. 161.)
