geologic features and a bibliography by Professor C. P. Berkey, 
to which is appended a description of a new base map of Porto 
Rico by Dr. Chester A. Reeds; (3) Geology of the San Juan Dis- 
trict, an area of about 500 square miles on the northern side of 
Porto Rico, by Dr. Douglas R. Semmes. 
The final reports on the botany of the Survey will take the 
form of a descriptive and annotated flora, based largely on 
specimens in the herbarium and museum of the New York Botani- 
cal Garden obtained during several collecting expeditions by 
members of the staff and special agents from 1901 to I9I6. 
Much manuscript for these reports has been prepared, and it 
is planned to publish the first botanical part in 1920. 
The publication of these survey reports will go far toward 
making Porto Rico the key to the geology and natural history 
of the West Indies.
