participated in a botanical expedition to Western Cuba, supplied 
the botanist of an expedition across South America to explore the 
Amazon basin (Mulford Expedition), and of the Astor Expedi- 
tion to the Galapagos Islands. It has sent its own expedition to 
study the wild and cultivated Iris of | 
apan, and, as a matter of 
routine, has been continuously engaged in botanical field work in 
various parts of the United States. The results of these expedi- 
tions have been embodied in published reports and scientific papers. 
In the matter of botanical publication the Garden, by coopera- 
tion with the Botanical Society of America and the Ecological So- 
ciety of America, has made possible the foundation of two research 
journals—the American Journal of Botany, monthly, now (1935) 
in its twenty-first volume, and Ecology, quarterly, now in its fif- 
teenth volume. By cooperation with the Editorial Board of the 
bimonthly journal Genetics, the Garden has made possible the con- 
tinuation of this journal beginning with its sixth volume (for 
1921). These three journals circulate in 53, 48, and 37 countries, 
respectively. 
The Brooklyn Botanic Garden REcorp circulates in 59 countries, 
the Memoirs (scientific monographs and papers) in 47, the Con- 
tributions (reprints of research papers) in 34, and the popular 
Leaflets in 28. 
The annual exchange of seeds of native American plants for 
seeds of the native plants of foreign lands involves 160 botanic 
gardens located in 40 countries. The List of Seeds Offered in 
Exchange goes to each of these gardens as the January issue of 
the Recorp. It is doubtful if any Brooklyn institution, scientific, 
educational, or commercial, is known over a wider geographic 
range. 
As usual, the routine of investigation has involved the exchange 
of research material and ideas with investigators in many foreign 
lands. The educational program of the Garden has served as sug- 
gestion and incentive to gardens in other countries. [ive of the 
letters of congratulation on the twenty-fifth anniversary, received 
from five different countries, contained the following statements : 
“T have alwavs read your annual reports with great interest, and 
in many cases I have found in them ideas for organizations I en- 
deavored to realize in my country.”
