200 Mr. Hutton on the Stratiform Basalt. 



fathoms in it, two of which were in a Shale bed, and fourteen in the 

 Whin, where they stopped, the vein in its lower portion having proved 

 unproductive. 



The Limestone in a quarry at Gallow Hill, north-east of Harrington, 

 is much contorted ; it is above, and must be very near the Whin, as im- 

 mediately behind the farm house a quarry has formerly been worked in 

 that stratum. To the north-east of this the Whin again appears in the 

 front of the farm house at Green Leighton Dyke Head. At Newbig- 

 gin, near Fallowlees, at the southern extremity of the parish of Roth- 

 bury, columnar Basalt may be seen on the right bank of Fallowlees 

 Burn. 



On Ward Hill, south of Forest Burn, the Whin forms the capping 

 of the hill above a Limestone. A seam of Coal is here worked below 

 the Limestone at a spot called the Lea, or High Healey Hirst. 



A large quantity of Iron scoria is found upon this hill, denoting it to 

 be the site of an ancient Iron work : this circumstance probably in- 

 duced a late trial to be made of the Whin itself as an Iron ore. 



In Maggie Burn, which runs into Forest Burn, the Whin may be 

 seen, but was no where found beyond this, until we reached a farm 

 called Shield Dykes, about four miles north-east, the vale of the Coquet 

 cutting through it. Near Shield Dykes, at a spot called Swinelee Hill, 

 it makes its appearance in large masses above the surface, and is worked 

 in a quarry for the use of the roads. The Whin is also worked for mend- 

 ing the great north road in Hampeth Quarry, a mile and half north- 

 east of Shield Dykes. North of Snipe House, the "Whin is seen by the 

 side of the road to Rugley. 



At Rugley it has been quarried, as also at Green's Field, near the edge 

 of Alnwick Moor, where it is three to four fathoms thick, and reposes 

 upon a Shale of a light ash grey colour, used as a hone and sharpening 

 stone. At Hope House, on the road side, below the tower at Swans- 

 field, it has been formerly worked, but does not appear again until we 

 reach Harlow Hill, near Denwick, on the opposite side of the valley, 

 the denudation caused by the river Aln having removed it along with 

 the other beds of the series.
