stone thrown up, about three-quaneis of a mile in length. Every 

 joint and seam of this limestone is stained with iron ore; and in 

 some cases the stain penetrates into the limestone to the extent of 

 three-quarters of an inch. Yet in no one single point — and the 

 reef has been diligently searched — has a single barrowful of ore 

 ever been found. 



To the N.W. a valley intervenes between these mines and the 

 limestone on the opposite side of this valley, which is only about 

 two hundred yards wide, large masses of limestone are again 

 thrown up, vast quantities of which have been taken in connection 

 with the works at Barrow for smelting purposes. Every seam and 

 joint of this rock, too, is stained with iron, yet in no single case has 

 ore been found. This rock lies exactly to the south of the great 

 Park Mine, and where it dips and slopes to the back of the valley, 

 the ore is found. Between this and Mousell the slate rock comes 

 in, and underlies at an acute angle the ore which is here found. 



Lying as they do on the opposite side of the valley, these mines 

 somewhat alter their run, and instead of trending N.W. and S.E, 

 they go W.S.W. and E.N.E. Their formation is most irregular. 

 In places large masses of rock jut out into the ore. In other cases 

 large masses of ore project into the rock ; and the formation is 

 equally irregular on both sides of the mines. The ore varies in width 

 from one to three hundred yards, and the total length is about one 

 thousand yards. 



The workings have not reached a sufficient "depth to show what 

 the ultimate result will be ; but from experience which has been 

 hitherto acquired at one hundred and twenty fathoms, it would 

 seem likely that at a greater depth, the slate rock on one side, 

 and the limestone on the other will meet, the slate dipping 

 below the limestone, and the ore will thus be cut out. At the 

 E,S,E, end, the ore in one place is within thirty feet of the 

 surface, and with nothing but drift over it. But to the W.N.W. 

 there is a depth of forty fathoms before the ore is reached. In 

 this forty fathoms some drift exists near the surface ; then comes a 

 huge mass of red clay, and beneath this, white sand. The rock, 

 which is level with the ore to the E.S.E., is very much above it to
