to 
of the palisades exceeds that of the leeward. The 
shore rises steep from the water on the one side, with 
the billows. breaking in heavy surges, the foaming 
waters washing up the materials with a rapid rush. 
On the inward side, the ground shelves of into 
shoals, and lagoons arched over with the mangrove. 
The desert sands that intervene, are seen ridged into 
ripples by their shifts before the gusty sweep of tlre 
breezes. They do not éohere as rippleemarks made 
by water do, but change continually, heaping them- 
selves up against every obstruction. 
The Cashaw-tree that grows so vigorously in- -land 
ig unable to make head against the bluster of the 
sea-breeze. It springs up with no trunk in the face 
of the wind, but starts off low and bushy, and fre: 
quently shows that it has been damned up, and over- 
whelmed by currents of drifted sand. 
There are some masses of cohering pebbles forming 
laminated fragments of conglomerate, lifted by the 
Surges into the inclined position in which they lie 
on the beach. The surges wash over them, and the 
broken waters in their refluent course as the billows 
retire, cut them into pieces and patches, and channel 
them into deep and shallow lines. 
Among the shingles on the shore, I find fine spe- 
cimens of the close-grained stone, a supposed las 
from which lithographic stones have been taken. 
The pebbles of the beach are porphyry and trap, and 
afew granites. Masses of gypsum occur, and some 
dark=tinted limestones. 
The vegetation of the beach consists of asclepias 
gigantea: prosopis juliflora: capparis cynophallo-
