At Key West Professor de Vries and I separated. When 
eee de Vries took the boat for Cuba, I proceeded to Big 
Pine Key. Upon reaching this island I encountered an epidemic 
of mosquitoes which made existence almost impossible. How- 
ever, with occasional periods of relief in the breezes along the 
beach, I managed to make a large collection of the plants growing 
in the interior of the island. Several species new to science 
were found in the pinelands and also some West Indian plants 
not before collected in the United States. 
Your communication relative to the collecting of the seeds of 
ee mer s of the Everglade Keys for experimental 
purposes in Bermuda awaited me at Miami upon my return from 
Key West and Big Pine Key. A week was devoted to securing 
the desired seeds, and the seen herbarium specimens, 
from within a radius of about 6 miles of Miami, with the excep- 
tion of one day on which a se rainstorm came up from 
the tropics, and during which high winds also prevailed. Nearly 
eight inches of rain fell during the day! This deluge brought 
so that collecting in that region was made impossible for some 
eeks. Beginning with the following week collections were 
made in the vicinity of a canal recently dredged through the 
mangroves and sand-dunes between Bull’s Island and ie head 
of Indian Creek on the peninsula opposite Miami. The flora of 
the hitherto ane a parts of the Mangrove-formation was 
very interesting, an e growth of the various halophytes with 
their several shades i green on the recently excavated sand of 
the canal-banks was luxuriant beyond anything I had before 
observed. As in the case of the banks of the Miami drainage 
canal, the recently made banks of pure lime-sand supported an 
exceptionally luxuriant growth of plants. Following this, a 
canal recently dredged from Snapper Creek prairie to the 
was investigated. These new channels through land hitherto 
not easy of access always show phenomena of s ecial interest 
and yield good results in the way of ie of speci 
A four days’ expedition to Big Pine Key and the acer 
keys was planned, but stormy weather defeated its accomplish-
