Mr. Jones was, I believe, the first to call attention to the 

 Submerged Forests, at the Royal Drough, in his valuable paper 

 on the ^' Sharpness Point District," published in the third vol. 

 of the Transactions of the Club, and I am indebted to him for 

 the following note: — "As Submerged Forests are generally 

 made known to us by the exposure of their trunks and contents 

 by the action of the sea, may we not infer that their sub- 

 mergence must have been of a more sudden character than that 

 exhibited in most geological operations. For example, we see 

 that such fruits as Hazle nuts and the like, reeds, grasses, iris 

 leaves, &c., were not washed away or decomposed during the 

 submerging operation, but when once exposed again, crumble 

 and decay in very brief time. The fact of their occurring upon 

 the shore, i.e. the lowest point of erosion indicates that the 

 upheaval has been slower than the submergence." 



Mr. God WIN- Austin observes in his paper that *'The greatest 

 depth at which Submerged land-surface has been ascertained 

 is about 120 feet; a rise of such amount would place the whole 

 of the Bristol Channel in the condition of dry land, and such 

 probably it was at the time of the forest growths ;" and Sir 

 Chables Lyell states,* " There is good reason to beKeve that

 Wood and Eome's paper, p. 182, of the " Q^aarterly Journal of the Geological 

 Society" for May, 1868.
