100 
inhabitants are said to number about 40; cotton grows there 
exceedingly well and considerable is produced; cassava, bananas, 
and a variety of garden vegetables are cultivated; the prin- 
cipal industry at present is charcoal-burning, and the low dense 
natural forest of the plain is rapidly paneer under the 
machete. This forest is of great interest, being composed of a 
large number of kinds of trees, averaging about 25 feet high, 
and is inhabited by two rare orchids and by many species of 
low plants. The butterfly orchid (Epidendrum papilionaceum) 
is very abundant, and its purplish flowers clustered at the en 
of long stalks were the floral feature at the time of our visit. 
The island is wholly United States Insular G property, 
and it would be well if the remainder of this forest could be 
preserved. It evidently extended originally all over the plain; 
the part nearest Sardifiera and other areas were long ago cut off 
by a German colony, who worked the phosphate mines, and 
evidences of this occupation are to be seen in massive concrete 
nks and ruins of other structures; the departure of these 
residents is said to be due to differences of opinion between the 
German and Spanish Governments 
Professor F. L. Stevens visited Mona on December 20 and 21, 
1913, and was evidently diligent in botanical collecting, for, 
in addition to his special errand for studying the parasitic fungi, 
he brought specimens of about 150 species of flowering plants 
to the Agricultural College at Mayaguez, and sent them to me 
for study; we mostly collected only species not observed by him. 
The two collections indicate a total flora of flowering plants of 
about 230 species, and it is improbable that many others exist 
there. The land cryptograms wma outnumber the flowering 
aes so that the total land fl of Mona is apparently as 
i number of a lowering plants are, however, 
mae as weeds of cultivation and are not a part of the 
ciiee flora. Marine algae are abundant on the fringing reefs 
ong the western coast, but a ‘‘norther,”’ which blew strong for 
re days and caused the ‘‘Dama’’ to flee for safer anchorage, 
prevented any sea work during our stay. On February 25, we 
moved camp southward to Ubero, and established it in our large
