ON THE OCCURRENCE OF QUARTZITE AND OTHER BOULDERS IN THE 
LOWER COAL MEASURES AT WORTLEY, NEAR LEEDS. 
BY CHAS. BROWNRIDGE, A.SSOC. M.LCE , F G S. 
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 coal- 
fields of Leicestershire, Lancashire, Derbyshii-e, 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 ^Ies>rs. 
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 iron- 
stone aie 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
