rocks. Very few granites bad been found in the Clitheroe 
district, but a pocket of sand with broken shells had been 
reported from Whalley, showing that the Irish Sea glacier had 
advanced thus far. 
On the Saturday morning the party started early, under 
the leadership of Mr. James Walsh, B.Sc, of Blackburn, to visit 
Pimlico quarry. One of the features of the Clitheroe valley con- 
sists of a number of rounded hills, which have been termed knoll- 
reefs, and which many geologists consider to represent separated 
coralline and shell reefs, whilst others refer their formation to 
earth movements. The Pimlico quarries have laid bare one of 
these knolls in a remarkable manner, showing its structure very 
beautifully, and laying open for the fossil-hunter exposures 
wonderfully rich in organic remains. The limestone is, indeed, 
a mass of crinoid remains, with large numbers of heads in 
excellent preservation. After good bags had been secured the 
party drove by way of Chatburn and Downham to Brash 
Clough, where sections of the lower strata of Pendle Hill were 
seen. Above the shales-with-limestones comes the Pendleside 
Limestone, which is thick-bedded with chert bands. This is over- 
laid by the Pendleside Grit, which forms the lower ridge of 
Pendle, above which comes a hollow groove due to the softer 
Bowland Shales. The summit of Pendle is composed of the 
lowest beds of the Millstone Grit series. Leaving Brash Clough 
the Sabden road was followed over the escarpment at Pendle 
Nick, and the Millstone Grit quarries at the summit were seen, 
but a haze interfered with the full appreciation of the view of 
the ridges and valleys of the Pendle range. The descent to 
Sabden is down the dip slope of the Millstone Grit, and at 
Sabden the black shales between the Fourth and Third Grits 
come on. It is in these shales that the longitudinal valley of 
Sabden has been excavated. At Whalley the interesting gorge 
of the Lancashire Calder was seen, cutting right across the 
prominent ridges of Millstone Grit to the Burnley Coal-field. 
A visit was paid to the interesting old Parish Church, but, 
unfortunately, the Abbey grounds were closed. The party
