with seams of sandstone and dip slightly southwards. There is much 

 more matrix and a smaller quantity of fragments than in the two 

 preceding exposures. 



6. BundlellTead and the Ness.'^ 



As Bundle Head is half a mile south of the Ness, it should, strictly 

 speaking, be described first, but it is more convenient to describe the 

 two as approached from Teignmouth. 



Crossing the Teign at the ferry from Teignmouth to Shaldon, 



1 walked to the Ness (at the mouth of the Teign), passing on the 

 way several large blocks of quartz-porphyry on the beach. The 

 conglomerate at the base of the Ness contains a considerable 

 proportion of Devonian limestone, often visibly fossiliferous, 

 purplish-red sandstone, some red quartz-porphyry, and a few 

 fragments of the so-called lydian stoue. Going southward round 

 the foot of the Ness, I found lying loose upon the beach a block of 

 red quartz-porphyry measuring 3 ft. by 2 ft. 6 in. by 2 ft. 8 in., and 

 eighteen paces to south of it another block of the same rock 



2 ft. 10 ill. by 2 ft. 4 in. by 2 ft. 4 in. Both of these blocks agreed 

 petrographically with the red quartz-porphyry blocks embedded in 

 the conglomerate. This red quartz-porphyry is very characteristic 

 of these Permian conglomerates and breccias, and its petrographical 

 characters will be referred to later. A few yards south of the last- 

 mentioned loose block is a mass of the same red quartz-porphyry 



3 ft. 6 in. by 2 ft. by 2 ft. -\- partially embedded in the conglomerate, 

 and another few yards south a similar block 2 ft. 10 in. by 2 ft. by 



1 ft. 5 in. also in the conglomerate. A thousand paces south of the 

 block last mentioned, at a promontory which is, I believe, Bundle 

 Head, and lying among great fallen blocks of the conglomerate, is 

 another loose block of red quartz-porphyry 5 ft. by 3 ft. by 3 ft. ;. 

 six paces from it is another similar block 3 ft. by 3 ft. 6 in. by 2 ft. 9 in. 

 Only 23 paces further south is a block of Devonian limestone 



2 ft. G in. by 1 ft. 6 in. by 1 ft., apparently embedded as to its lower 

 surface in the conglomerate, though it may have been squeezed 

 down into it by the action of the sea. Yet most of the blocks in 

 the conglomerate hereabouts are only 3 to 6 inches in diameter. 

 Five paces from the last limestone block another, roughly elliptical 

 in form, 3 ft. G in. by 2 ft. 8 in. by 1 ft., lies loose on the beach. 

 Eleven paces from the limestone block last mentioned (and lying on 

 the top of fallen conglomerate masses) are two blocks of red quartz- 

 porphyry lying close together, one measuring 4ft. Gin. by 4ft. by 

 2 ft., the other 4 ft. by 4 ft. by 3 ft. Eight paces further south is 

 the largest boulder (of any rock) I saw on the South Devon coast, 

 a block of red quartz-porphyry, 5 ft. 4 in. by 5 ft. by 3 ft. G in., to 

 which I shall refer again. It lies loose on the beach amid huge 

 fallen masses of conglomerate. Four hundred and fifty paces south 

 of the last (after passing several others) I found lying loose on the
