THE MEDITERRANEAN NATURALIST

Branching off' from it are the two galleries, the 
one on the left-hand side and the other on the 
righthand side of the chamber. 
That on the left is 10 feet long, 8 feet wide, and 
3 feet high. It was filled .with a dry indurated 
clay, intermixed with which were numerous 
rounded boulders, fragments of pottery, and bones 
and teeth of sheep, pig, dog, and ox. 
A section of the deposits in this gallery exhi- 
bited the following sequence of beds:— 
A. A stratified layer of rounded boulders inter- 
mixed ivith an indurated red clay: one ■ foot 
in thickness. 
B. A stratified layer of indurated red clay/, three 
feet in thickness , containing teeth and bones of 
sheep , pig , dog, and ox, together ivith occa- 
sional angular fragments of Lower Carolline 
Limestone that had, evidently been derived 
from the roof or sides of the chamber. 
The bottom oi the gallery was much fissured; 
and the distal extremity terminated in a close 
round end. 
The gallery on the right hand side has a funnel 
shaped entrance which is about 4 feet high and 7 
feet wide, after passing through which it opens 
out into a spacious chamber measuring 15 feet 
wide and from 3 to 6 feet in height. This in its 
turn contracts into a narrow passage which leads 
into another enlargement. 
The total length of the gallery is 132 feet, in 
the course of which it expands and contracts 
five times. 
The width varies from 6 to 15 feet; and the 
height from 4 feet to 2 feet 3 inches. 
Like the other parts of the cavern the roof and 
sides are much fissured ; but none of the fis- 
sures are of any notable size. 
For a considerable portion of the length of the 
gallery progress can only be made by lying at 
full length and sliding over the wet clay on ones 
side. In consequence of this the people of the 
district know nothing of the nature or extent 
of the inner galleries and, therefore, like many 
other of the localities in the islands which are 
difficult of access, this cavern, too, has its 
legend. (1) Chev. G. Saxe the Russian Consul 
(1). It is said that this cavern is a portion of | 
an under-ground passage which terminates at j 
Asciak, a village three miles away. 
accompanied me in this exploration; and assisted 
mo in taking the measurements. 
The gallery is filled to within a few feet of the 
roof with a very plastic, greyish yellow clay. A 
section cut through it shewed it to be very homo- 
genous in character; and a series of borings re- 
vealed the fact that it varied but slightly in its 
thickness in any part of branch. 
From the excavation, which was made near 
the mouth of the gallery, several teeth of Canis , 
a portion of a skull of Sus scrofa, fragments of 
the limb-bones of Cervus barbarus and numerous 
specimens of a species of Helix were found. 
From the configuration of this cave as well as 
from the stratigraphical and lithological cha- 
racters of its deposits, it is evident that it owes 
its origin to the sarnie or to similar causes to those 
that were in operation when the Har Dalani 
beds were laid down.. Being situated at the same 
height above the bottom of the gorge bed, it is 
probable that it was flooded by the same waters 
that assisted in depositing the other cave beds; but 
its smaller dimensions as well as the inaccessabi- 
lity of its situation rendered it but ill suited to 
receive the animal and other remains, that were 
brought down by the flood waters of the gorge; 
and hence the organic remains that occur so 
plentifully in the Har Dalam Cavern, are here 
found to be almost absent. 
The occurrence, however, of a rude coarse kind 
of pottery associated with the remains of such 
domesticated animals as the goat, sheep, ox, 
and dog, in the superficial layers, indicate its 
occupation by man ; but the nature of the pottery, 
the sub-fos T condition of the bones, and the 
position of the remains in the layers all tend to 
show that the occupation could have been of 
no very recent elate
