Rhtetic Black Shales, according to 

 Mr. H. B. Woodward, are absent 

 — is situated near the Moreton- 

 Pennine anticline ; Dunhamp- 

 stead and Crowle — where the 

 greatest thickness of the Ilhaetic 

 Series obtains in Worcestershire 

 — are situated on a continuation 

 of the Cleeve-Hill synclinal axis 

 (see map, fig. 1, p. 350) ; and 

 the Birdlip anticlinal axis makes 

 in the direction of Lassington. 

 This is remarkable, but, as 

 already stated, it is not desirable 

 that the Lassington section be 

 discussed for the present purpose : 

 the Denny-Hill section, however, 

 shows for certain that there is 

 an anticline in this neighbour- 

 hood. Again, between Pains- 

 wick and Stroud a synclinal 

 flexure is noticeable in the 

 Inferior-Oolite rocks, and, what 

 is more, it will be observed that 

 it follows somewhat closely upon 

 the Birdlip anticline. Such is 

 the case in the Bhsetic also 

 at Denny Hill there is evidence 

 of the proximity of an anticline, 

 while at Chaxhill — but 2\ miles 

 distant — there is very striking 

 evidence of a syncline.

To sum up, then, it will be 

 noticed that — confining our 

 attention to the rocks of 

 North- West Gloucestershire and 

 Worcestershire — there is evi- 

 dence to suggest that there were 

 earth-pressures at work at the 

 close of the Keuper Epoch, which 

 caused the deposits to be thrown 

 into slight synclinal and anti- 

 clinal flexures. In the depressed 

 areas the earlier deposits of the 

 Hhaetic were laid down, and 

 successive overlap on to the marls 

 seems to have taken place (fig. 2). 

 Unfortunately, the products of 

 the Rhaetic Beds that are of economic importance are not numerous :
