The presence of boulders in the coal measures in various localities affords matter for interesting speculations bearing on the conditions under which the deposition of the carboniferous strata took place. Boulders have been found and recorded from the coalfields of Leicestershire, Lancashire, Derbyshire, North Staffordshire, and the Forest of Dean, but none appear to have been recorded from this immediate district. The position where these boulders were found is situate in the fork of land bounded by the London and North Western and Great Northern Railways, the Gelderd Road and the Farnley Beck. They were got from the pit known as ‘No. 1 Black Bed pit.’ The whole of this neighbourhood is worked for the Wortley fire-clay by Messrs. Ingham and Sons. Above the fire-clay the better bed coal is got, and at a still higher level the black bed coal and the outlying ironstone are worked. It was in the last-named beds that the specimens were found. The depth of the black bed coal from the surface is here 30 feet. The largest of the boulders is a coarse gritstone, nearly spherical in shape. Its dimensions are 2 ft. 6 in. by 2 ft.; it has a fairly smooth polished face, with slight striae. This was found embedded in the ‘bind’ or clayey shales, just overlying the coal. The other three boulders (or pebbles) are quartzites and much smaller in size, varying from 11 in. by 9 in. to 3 1/4 in. by 2 1/2 in., and were all ...
