ever-threatening downfall of debris. This was distinguished as 

 Working 0. 



To consider, then, these three sets of operations in succession. 

 Working A has not progressed very far, but will receive' more attention 

 shortly. An additional 5 feet of penetration has been accomplished with 

 a breadth of 6-8 feet, bringing up the total distance cleared from the 

 entrance to 30 feet. Some very heavy quarrying has been necessary 

 here which has involved the use of dynamite, the upper portion of 

 the debris consisting of large blocks wedged tightly against a rather 

 shaky roof ; so that it is necessary to proceed with great circumspection. 

 Worked flints occur sparsely at about 2-4 feet above the bench-mark 

 from which floor-level is measured; there is very little bone to be met 

 with. Working B has been highly successful, and the cave is now clear 

 across its entire front. The central part of the talus which has just 

 been removed proved to be almost sterile, but a richly implementiferous 

 bed reaching from near floor-level to a height of 14 feet was found to 

 exist under the ledge projecting some 1 2 feet outwards along the eastern 

 side-wall. The spoil collected here in the shape of worked flints, together 

 with cores and hammer-stones, must amount at least to a hundred- 

 weight. There was found also a good deal of bone in fair condition, rang- 

 ing in size from the minute remains of lemmings to a huge knuckle-bone 

 belonging probably to a rhinoceros. It is noticeable that a specially 

 fine set of implements occurred near the very top of this bed, the form 

 of these tending towards that elongated leaf -shaped pattern which has 

 been termed ' hemi-solutrian.' Thus it would almost seem as if \ve 

 had to do here with a later and more evolved product of Mousterian art 

 than is to be found in the lower deposits of this cave ; though it is true 

 that in other places where the implementiferous bed is much thinner, 

 extending at most to a foot or two, there was no apparent correlation 

 between quality of workmanship and stratigraphical position. Working 

 has also proved very fertile so far as it has been pushed under the 

 projecting shelf of the eastern wall, namely a distance of 27 feet from 

 the entrance. Here the presence of a former hearth was indicated by 

 a quantity of burnt bone. Flint was plentiful, but tended to be of 

 coarse pattern. So too along the opposite side-wall the quality of the 

 worked flint would seem to deteriorate as we penetrate into the depths 

 of the cave. A sufficient explanation is probably to be found in the 

 fact that the finer work needed the better light. Further, at the angle 

 situated about the centre of the cave where Working C passes into 

 Working A, the removal of a large block weighing some eight tons 

 revealed the clearest indication hitherto encountered of the way in which 

 the intrusive cave-filling is related to the ancient floor of occupation. 

 At this spot a definite line can now be traced, of irregular height, but 

 averaging 6-8 feet over bench-mark. Below this line everything is 

 cemented together into a compact breccia, whereas above it the rock- 

 rubbish is quite loose. At the top of the solid mass occurs a sandy 

 deposit about 1 foot in thickness which is finely laminated and has in 

 places almost the consistency of sandstone. This is apparently quite 

 destitute of bone-refuse or flint-chippings, though they occur again in 

 the looser rubbish above it. Thus it would seem as if the ancient floor
