UPHILL BONE-CAVES. 
rests directly on the limestone. In one place there had for- 
merly been a communication between this chamber and 
another below, this being subsequently blocked by fragments 
of limestone wedged together. 
A second somewhat larger cavity occurs at a lower level, and 
contains a mass of rubble or cave -earth of considerable thick- 
ness — six to eight feet in places. In this deposit numbers 
of bones and teeth occurred, generally in a more broken state 
than in the upper cave. An irregular fissure or chimney 
passes off from this cavity in a north-north-easterly direction, 
widening in places by erosion along the bedding planes, and 
being mainly filled up with cave-earth or rubble. This fissure 
eventually opens into an irregular cavernous hollow from 
which other fissures or chimneys passed off, one chimney being 
in one place nearly circular in outHne and six feet in diameter. 
Some worked flints and scrapers, and a spear head of a rude 
character were found in the same rubble as that containing 
the hyaena and rhinoceros bones, but Mr. Wilson says : "I 
cannot consider the evidence of their contemporaneity satis- 
factory. The rubble has certainly undergone some displace- 
ment in finding its present position, and it is quite possible 
that in this process later objects may have been intermingled 
with the earher ones." 
After Mr. Wilson's death a committee, with Professor Lloyd 
Morgan as chairman and Mr. Herbert Bolton as secretary, was 
appointed for the further investigation of the Uphill bone-caves, 
and in aid of this object a grant was made from the British 
Association funds. Many more bones were collected and 
identified, but the cavities in which these bones were found 
were probably none of them caves of occupation, or the actual 
dens of the hyaenas. The bones have probably all been washed 
by water into the positions in which they were found. The 
actual cave of occupation has not yet been discovered.
