which the veins occur. The total quantity of ore which has been 
produced from the Cononley veins is about fifteen thousand tons. 
The only other places near, where any ore has been produced from 
the Kinderscout grit is Cowling, about one and a half miles west of 
Cononley, where a trial was made, and three and a lialf tons of ore 
raised. In the limestone of the district there are, north and south, 
veins running across the Carleton Park Head, and also of the 
Skipton Haw Bank Quarries. From tlie former place about fifteen 
tons have been obtained, and from the latter about thirteen tons. 
These veins are very uncertain, but carry ore of good quality in self 
lumps in the clay lode. The paper was illustrated by a plan and longi- 
tudinal section of the upper veins. 
For several years prior to 1879 occasional chips and imple- 
ments of flint had been found on the moors covering the Penine 
Hills. These incited Messrs. Robert Law and James Horsfall to a 
more thorough investigation of the surface of the moors from which 
the peat had been denuded. Wherever patches of the surface thus 
exposed were found one or more fragments of flint were nearly 
always discovered. The most striking example was met with on 
March Hill, a conical eminence overlooking the Vale of Marsden ; 
from a few small patches of bare ground on its southern surface 
more than tw^o thousand flints were obtained. They included flint 
cores and one leaf-shaped arrow tip. The flints occurred in a dark- 
grey sand beneath the peat and a peaty clay. The sand is about 
six inches thick, and flints appear to occur indiscriminately through- 
out the whole thickness. Beneath this the sand assumes a red 
ochreous tint, about twelve inches in thickness, resting on Yoredale 
shale. Middle Hill, near Whitworth, also proved very remunerative. 
The peat had been burnt off some years previously, and atmospheric 
agents had lowered the loamy sub-soil at least an inch, proved by 
little earth pillars, capped with stones, and occasionally flints, here 
and there on the surface. Three hundred and fifty pieces of flint 
were gathered at this spot. Broken flints and arrow-heads were 
found at Knowl Hill, and on Midgley Moor, two miles north of 
IMytholmroyd, and also in numerous other localities. A total of 
3,824 flints were found, and of these 83 had been worked into
