ON PALAOLITHIC EXPLORATION IN JERSEY. 231 
which the cave penetrates brought to light a considerable fissure, 
about twenty feet higher than the level of what is to be seen of the 
cave-roof; and this may very well turn out to be the upper end of this 
hypothetical! funnel. For the rest, these topmost parts of the cave- 
filling proved to be absolutely sterile, with the single curious exception 
that right at the back of the cave, some thirty-five feet above the floor, 
a piece of bone was noticed to jut out’ When this was with some 
difficulty rescued from its rather inaccessible position, it was found 
to have all the appearance of extreme antiquity, and is probably 
assignable to Bos. Presumably, therefore, it is contemporary with 
the cave-filling, and came down therewith from above. 
It was calculated that it would be just possible with two months’ 
work to carry a clearing about eighteen feet broad right across the 
mouth of the cave to its eastern side-wall, since its upper and visible 
portion, distant about thirty feet from the opposite side-wall, showed 
a perpendicular drop which might be presumed to extend indefinitely 
downwards. On April 8, however, it was discovered that this wall, 
along the whole breadth of the eighteen feet in process of clearance, 
was undercut, at a point about sixteen feet above floor-level, by a 
further cavity. To judge by the narrow section opened up, there is 
not less than twelve feet of additional penetration to be reckoned with 
on this side. Shielded as it is by its lower roof, this annexe would 
appear to be at once remarkably dry and free from shattering falls of 
rock. Thus it offers conditions more favourable to the preservation 
of bone than the high-domed cave on which it borders, and would be 
an ideal place in which to come upon human remains. This discovery 
led to a modification of the original plan, the breadth of the clearing 
being reduced to about ten feet, so as, consistently with thorough 
exploration of the portion of floor uncovered, to stretch forth a 
‘feeler’ in this tempting direction. Nothing short of a fresh bout 
of excavation, however, supported by a grant no less substantial than 
the last, will enable the Committee to cope with this unexpected 
lateral extension of the main cave; not to speak of the rearward parts 
of the cavern which are likely to prove more or less prolific also. 
In proceeding towards the eastern wall it was at first impossible to 
note any stratification in the gradually thickening floor owing to the 
large blocks distributed through it. At about twenty feet, as measured 
from the western side, there was, for the first time, clear evidence of 
some sort of stratification. For three feet above floor level there was 
a bed of thick ashes of a deep black colour. Above for about one 
foot succeeded an almost completely sterile layer. Then, for another 
two feet, occurred frequent implements in a layer of brownish clay, 
interspersed with slight traces of a darker matter. It was at first 
thought that the implements of the lower layer were rougher, and 
that, in particular, the typical Mousterian ‘ point’ was absent. Sub- 
sequent observation, however, controlled by careful segregation of the 
finds from each layer, failed to bear out this view, some of the 
finest points (one of them, however, being worked on both sides, and 
in this way suggesting an older style of manufacture) being found in 
the lower bed. Of course a more detailed examination of the products
