or grinder about a. The ellipse, instead of being composed 
of a single row of holes as in other instances, is composed 
of a double line of holes bored apparently on radii drawn 
from a. These double holes are of the second size. In 
front (east) is a semi-circular row of holes of the same size, 
and about the whole is another row of the smallest holes. 
The slope of the rock is from south-west to north-east ; and 
to carry off the water, channels have been cut into the siir- 
face on the more elevated side, several inches in depth and 
width. 
At the eastern extremity of the hill is a cave of triangular 
outline, approached by a low entrance from the north. 
This cave is formed by the overlapping of strata and the 
partial closing in of the cavity thus formed by the super- 
position of a huge mass of rock. The cavity is about 15 feet 
long and 10 broad, terminating in a curious little grotto at 
the western end. Owing to the manner in which the rocks 
forming it are thrown together, the cave is more or less 
open overhead throughout its whole length. At sunset the 
rays of ruddy light stream in through the western extremity 
of this cleft and illumine the grotto in a singularly pleasing 
manner. The cave has obviously been used as a human 
habitation. Without, along the shelving edge of the rock, 
which terminates in one irregular overhead opening, chan- 
nels of considerable depth have been cut in the stone in such 
a manner as to collect all water flowing down the face of the 
rock and to convey it into other and larger channels below. 
The floor of the cave slopes from west to east ; and border- 
ing the western or higher side, under the. overhanging ledge 
of rock, is cut a double channel running from the extreme 
inner end of the cave out to the entrance. The upper of 
these channels is the larger, the second and lower one 
being apparently intended for the overflow from the first. 
At the western end of the cave, and especially in the grotto, 
the natural slope of the floor has been altered by cutting
