Supply of Coal and Ironstone frorn the West of Scotland. 295 



and in the proportion of not more than one-fourth of the whole quan- 

 tity. The workable limit of this seam in the field to the east of Glas- 

 gow appears to be near the line of the large slip passing through the 

 Woodhall lands at the mill. On the west the boundary of its existence 

 is not distinctly known ; but it has not been found of quality worth 

 workmg west of Carnbroe. Towards the north it crops off before 

 coming to the south boundary of Cairnhill. The quality of this seam, 

 so far as seen, is not very regular, but varies in different localities. In 

 stating the quantity still to work, I have confined my calculation to 

 what is known of the seam around Faskine, and I estimate the area at 

 300 acres. 



Upper Coal. — At 48 Fathoms — Average Tlbichness, 40 Indies. — 

 This is the first or uppermost coal found in the Clyde basin. In thick- 

 ness, it ranges from 3 to 4^ feet, and its quality has been long famous 

 for household purposes at Eastfield, Stonelaw, and the collieries around 

 Glasgow. It exists in its best condition on the south side of the 

 Clyde, and on the north bank of it as far as ToUcross and Kenmuir. 

 At the latter place, and eastward, it gradually becomes inferior both 

 in thickness and quality. 



At no place out of the district described does the seam appear to exist 

 in a valuable condition. At Bredisholm, near Baillieston, and Drum- 

 peller, near Coatbridge, and throughout the Coatbridge district, it is 

 unworkably thin. At Drumbathie, near Airdrie, it is about 2 J fee t in 

 thickness, but not considered of workable quality. 



This seam has been worked for a very long period for the supply of 

 this city, and what remains of it is confined to patches lying between 

 Eastfield and Dalraarnock on the west, and Kenmuir on the east. 

 Estimated area still to work, 2,500 acres. 



Ell Coal. — At 63 Fathoms — Average Thickness, 96 Incites. — The 

 great thickness and excellent quaUty of this coal make it the most 

 valuable and important seam of coal in the whole district. It is the 

 principal seam worked in the recently opened-up Wishaw district, and 

 there is now a greater supply drawn from it than from any other seam 

 in the whole of the fields under consideration. This seam extends from 

 Glasgow in a south-eastern direction as far as Netherburn, which lies 

 about half-way between Hamilton and Lesmahagow. Its southern 

 boundary is near the large fault, known as the Eddlewood Dyke, which 

 throws up the strata to the south-west about 100 fathoms. The 

 breadth of the seam along the north side of this dyke averages about a 

 mile and a-half, as far as Hamilton on the south, and Holytown on the 

 north; from Holytown the northern boundary turns northwards to its 

 most nortliern limit at Stanrig, north-east of Airdrie ; thence the line
