Farther on, small rocky reefs isolated in the Everglades indi- 
cated the position of former hammocks. (See accompanying 
plate.) These, evidently once clothed with shrubs and trees 
growing in the accumulated humus, are now bare ragged rock 
nearly or quite devoid of even the common everglade vegetation. 
Burnt-Pine Island, Hammer Key, and neighboring hammock 
islands, both extant and extinct, are interesting as indicating a 
natural chain of connection between the Cape Sable region and 
the main body of the Everglade Keys. When the territory for a 
dozen miles on either side of the Dade-Monroe county line be- 
comes accessible, the gradation between the floras of the Ever- 
glade Keys and Cape Sable, as well as the relation of both of 
these floras to that of the lower Florida Keys, to which they are 
both related, will doubtless present many interesting problems. 
Although Hammer Key is widely separated from the Long Key 
Pineland, and is surrounded by the Everglades, it is not an Ever- 
glade hammock, but is almost identical with the high pineland 
hammocks of the Everglade Keys. It is on an elevated rocky 
foundation. Many of the typical high-pineland hammock trees 
are there, the wild tamarind (Lysiloma) and butter-bough 
(Exothea) being very abundant. The characteristic shrubs, 
vines, and herbs also grow there. 
Unfortunately, a drenching rain came up before we reached 
the Key and continued with more or less severity until we got 
back to Royal Palm Hammock. We and our luggage were 
thoroughly drenched, except our camera. This, of course, we 
had to protect at the expense of everything else, even if it was 
useless baggage just then. 
During a general and extensive collecting trip into the northern 
part of the lake region an attempt was made to get into the 
district west of Lake George for the purpose of rediscovering 
a prickly-pear reported from there many years ago. 
We drove from Miami to Daytona on or near the border line 
between two different plant regions, the “east coast strip” and 
the “south Florida flat-woods.’’ The former region comprises the 
line of narrow more or less active sand-dunes along the eastern 
coast of the state, the lagoons, and perhaps some of the adjacent
