Red Marlstone Rock (permian), little worn. 
Hcematite Iron Ores (probably permian), worn into round 
lumps. These are eagerly sought by the workmen for “ red 
raddle.” They resemble the richest specimens of iron ore as 
found at the Patricroft workings, but are apparently much 
purer, and more like the hoematites of North Lancashire. 
Coal and Coal Shales. Abundant. The coal in small 
cubical fragments, but in great quantity. One line specimen 
of coal shale with “ Anthracosia robusta,” well preserved, 
and one line frond of “ Neuropleris.” Oval nodule of pyrites 
or Brass lump” from the coal measures. 
Sandstones. White sandstone boulders very frequent, 
containing fossils, probably calamites and sigillarise, and 
chiefly resembling the white sandstones of the middle coal 
measures. 
Ironstone. Nodules of claybound ironstones frequent ; one 
very good example with line septaria in centre. 
The above list of boulders possesses some features of con- 
siderable interest. The granites and greenstones are very 
much the same as those found in the clays around Manches- 
ter, and which are generally supposed to have come from 
Cumberland and Westmoreland. These are much worn and 
have deep strise. 
' The limestones are such as occur in the Pendle district, 
and their presence confirms the author in his belief that the 
current which denuded the coal of the high-lying seams of 
Lancashire and as far north as Ingleborough, and scattered 
the boulders which we find in this clay, came from the north- 
wards, and probably from the neighbourhood of Ingle- 
borough. The quantity of coal in small fragments was very 
remarkable, and evidences very considerable denudation of 
the coal measures, as also the presence of so many boulders 
of coal measure sandstones and shales, such as occur through- 
out the district lying to the north of Chat Moss. The unworn 
fragments of the permian limestones and marlstones is an
