a mile and 4- deeper than those at Sutton. But as in fact they are dug near the 

 same depth, there must be a trap, or several traps down, which in all must 

 amount to that depth between these works Between Faringdon and High- 

 Littleton the same veins seem to retain their regular course ; but at Littleton 

 their undermost and deepest vein is the best coal, which at Faringdon proves 

 small. 



On the other hand, in the parish of Stanton-Drew, to the north-east of the 

 coal- works at Sutton, about a mile distant, and in the true course with those at 

 Sutton, the same veins are found again. But here they wind a little, and their 

 course or drift runs almost north, and they dip to the east ; which winding is 

 attributed to ridges, which the workmen have met with on both sides, and have 

 occasioned them to discontinue the work that way. At Stanton they have little 

 of the red earth or malm on the surface, but come immediately to an iron-grit, 

 or grey tile-stone, which is a forerunner of the coal-clives : in all other mat- 

 ters they agree with the works near Stowy. 



In the same parish of Stanton-Drew, a little to the eastward, they have 

 another coal-work, but the veins are in all respects different from the former. 

 Their drift or course is to the ] 1 o'clock sun, as they term it ; they pitch to 

 the 5 o'clock morning, and rise to land; consequently to the 5 o'clock evening 

 sun. There are several veins, but as yet only 3 are thought worth working. 

 The uppermost, about 3 feet thick, is a small lime-coal. The next is about 3 

 fathom under it, and about 2^- feet thick, fit for culinary uses : the undermost 

 is about the like depth under the former, only 10 inches thick, but good 

 hard coal. 



At Glutton, about 2 miles from these latter, in the same drift, viz. almost to 

 the south-east and by south, these last veins appear again. The surface here is 

 red, and so continues to 10, and sometimes to 14 fathom, and in other re- 

 spects they agree with the last-mentioned works at Stanton -Drew. 



At Burnet, Queen-Charlton, and Brisleton, there are 4 veins, which pitch 

 to the north nearly, and consequently the drift lies almost east and west. The 

 surface is red land, generally to the depth of 4 or 5 fathom. The uppermost 

 is from 3 to 6 feet thick at Brisleton, but less at Charlton and Burnet. The 

 next, called pot-vein, is 6 fathom under the former, 18 inches thick, all hard 

 coal. 3dly, The trench- vein, 7 fathom under the other, which is from 24- to 

 3 feet thick, all solid coal. 4thly, Rock-vein, always distinguished by a rock 

 of paving-stone, called penant, lying over it, the rock sometimes 20 feet thick, 

 or more, and therefore this vein is never wrought in the same pit with the 

 former vein, but about 200 yards more to the south, or to land, as they term 

 it. It is 7 fathom under the former.
