in the Galapagos group, and Cocos Island, including over fifty 
species hitherto unreported from that region. Upon his return 
to Brooklyn, these plants were identified and, in 1933, the manu- 
script on the Galapagos Flora was completed, after he had made 
a trip to England to check the plants collected on expeditions of 
English botanists. In 1937, the study of the ferns of the Gala- 
pagos and Cocos Islands was published. A valuable opportunity 
came to him in 1941, as recipient of a John Simon Guggenheim 
Foundation Fellowship, to spend three months in Ecuador for the 
purpose of studying the geographical distribution of plants, and 
specifically to compare the flora of that part of the coast of South 
America with the flora of the Galapagos Islands. Plants were 
collected in Ecuador, and a comparative study is being made with 
those collected on the Galapagos Islands. Investigations on the 
flora of Tennessee have involved trips to Middle Tennessee to 
study, with the cooperation of Prof. Jesse M. Shaver of Nashville 
and the Tennessee Academy of Science, the flora of a section in 
which the wild life is doomed, due to industrialization following 
the Tennessee Valley Authority project. Over 8,000 plant spec- 
imens have been collected and these, together with numerous photo- 
graphs, serve as the basis for a discussion of the Tennessee flora. 
Dr. Edgar W. Olive, the first Curator of Public Instruction, 
was especially interested in the cytology of the rusts. With Prof. 
Whetzel of Cornell University, an expedition was made in 1916 to 
Puerto Rico to collect and study fungi. They found the climate 
and other conditions unusually favorable for the growth of para- 
sitic fungi, and collections of more than 500 rusts and other para- 
sites, many of them new to science, were made, Studies on the 
life history of some of the common rusts of Puerto Rico were 
carried out. Duplicate type specimens of fungi collected on this 
trip are now in the fungous herbarium of the Garden, as well as in 
the Department of Plant Pathology, Cornell University. 
Dr. Arthur Harmount Graves, in addition to his activities as 
Curator of Public Instruction, with the assistance of members of 
his staff, has carried on investigations on the breeding of chestnuts 
the purpose of obtaining trees which will be blight-resistant, 
combined with theupright, vigorous growth, which characterized 
the American chésthut and made it so excellent for timber. Native
