Extract

In 1883 a scattered group of five boulders was met with in the workings of the Coleorton Colliery in the “Lount Nether” coal, at a depth from the surface of about 375 feet. They were all entirely enveloped in the coal, and occurred about 20 inches from the top of the seam. Four of them were found within a space of 20 yards of one another, but no two of them very near together, and the fifth occurred some 500 yards S.W. of the others. The coal-seam was of its normal thickness—namely, about 4½ feet. This is the seam marked “Lount 4” upon the Geol. Survey Sheet No. 46 of Horizontal Sections, and it is the lowest but one worked in the district.

1 I have indentified this mineral in a compact grey quartzite very like the above, which is among the Bunter pebbles, and find a grain of it in a slide cut from a similar quartzite which occurs on the Torridon road about three miles from Kinlochewe.—T.G.B.
