4. THE NATURALIST IN BERMUDA. 
“Vertical crevices abound, filled with ‘a substalagmite, 
much harder than the rock. In some places, the arrange- 
ment resembles that of veins in old slate or limestone. 
Where the partitions stand comparatively unimpaired by 
the weather, their planes constantly intersect one another, 
and thus form reticulations, once filled with the soft sand- 
stone. In all cases, the veins are younger than the crevices, 
from whatever cause these last may have originated. 
“Sr. Davip’s—Like St. George’s, the lower level of this 
island consists of a low, irregular belt of hard limestone, 
which commences in the centre of the north side, and con- 
tinues westward through Stock’s Point, till it appears, as 
above noticed, at Mullet Bay. 
“Cooper’s IstAnD.—Here I have remarked nothing, ex- 
cept the supposed cast of a tree at the north-east point. 
“Lone Brrp Is~aAnp affords an excellent horizontal 
section along the south side, of strata deposited in irregular 
undulations, and not contorted by any subsequent distur- 
bance. 
“ NONSUCH, CASTLE, and Goat IsLANDs.—As far as in- 
terest depends on variety, these possess but little. They, 
however, exhibit the frustra of the saddle-shaped structure, 
which may often be traced from one island to another, 
though frequently separated by considerable intervals. 
“BERMUDA, or the Main Island—The description given 
of the north side of St. George’s, answers in all respects to 
that of the whole of those coasts which are exposed to the 
ocean. On the south side, the sand has made several en- 
croachments, but only at Elbow Bay with any great success. 
The proprietor of the principal part of the land of this bay, 
remembers an attempt about seventy years ago, when the
