CAVES AT KIRBY MOORSIDE. 
CAVES AT KIRBY MOORSIDE. 
I mentioned in my former paper, that a second cave had been 
discovered in the vicinity of Kirkdale, which was reported also to 
contain bones, and that it had been closed by Mr. Duncombe till I 
should come down to examine it, which I did in July last, accom¬ 
panied by Sir H. Davy and Mr. Warburton. Our labour was lost as 
far as related to the discovery of more bones, or a second den of 
hyamas ; but it was repaid by the confirmation which this cave 
afforded in all its other circumstances of my speculations on that at 
Kirkdale, and by the discovery of another cavity in Duncombe Park 
containing animal remains, which throw much light on the mode in 
which the caves and fissures that were not inhabited as dens became 
filled with bones. I had also the satisfaction of demonstrating on 
the spot to Sir H. Davy and Mr. Warburton the actual state of many 
of the phenomena described in my account of Kirkdale. The cave 
at Kirby Moorside was intersected in working the face of a quarry 
of the same limestone as that at Kirkdale, at the north end of the 
town, and on the right side of a narrow gorge or valley called 
the Manor Vale, which descends from the north towards the Vale of 
Pickering, nearly parallel to the valley of Kirkdale, being about sixty 
feet broad, and bounded by slopes forty feet high, and forming one of 
the many smaller vallies of denudation excavated on this limestone 
by the diluvial waters as they subsided from the moorlands to the 
Vale of Pickering. A considerable portion of the right bank of this 
valley has been laid bare by the workings of the quarry, and on the
