Vol. 57.] PENDLESIDE GROTJP AT PENDLE HILL, ETC. 359 



stratified, and seem to form the upper portion of a series of such 

 beds which occur on the side of the hill 200 yards west of Fogga, 

 where some 30 feet of them are exposed in a quarry dipping at 30* 

 north-north-eastward, that is, under the Fogga rocks. Both these 

 quarries contain the typical Carboniferous-Limestone fossils. 



Sections showing a small thickness of compact limestone overlain 

 by calcareous shales also occur at Old Eock Plantation and within a 

 short distance of it ; Productus gigcmteus is found in the limestone 

 along with CyatJiopliyllum StutcJiburyi and crinoid-debris ; the dip 

 varies from 10° to 20° in a northerly direction. Three quarries in 

 the compact limestone, containing the same fauna, lie on the high 

 banks of the northern tributary of Swinden Gill : the lowest of the 

 three shows 18 feet of well-bedded thick limestones without shales ; 

 south of this is a gap in the sequence, but about 100 yards farther 

 south the black shales come on, the exact position of which is 

 doubtful. A series of dark limestones of Pendleside type occurs 

 in them immediately east of the railway in Swinden Gill. 



jSTewton Gill, 1 mile east of Long Preston, gives the following 

 section, kindly measured for us by R. Hornby, Esq., M.A. The 

 upper beds dip 10° northward, and the section commences about 

 a quarter of a mile south of the Grit-outcrop, the succession be- 

 tween the Grits and this point being sandstones, black shales, and 

 hard muddy shales without fossils.
