will, I think, throw much light upon 

 the section at Dove Point, now un- 

 fortunately destroyed by the encroach- 

 ments of the sea. 



Mr. Morton states that the Peat- 

 and Forest-beds " occur in the depres- 

 sions between the rock-exposures, and 

 they extend with little variation along 

 the middle ; but as they approach the 

 sides and ascend the slopes they become 

 thinner, and gradually end before 

 reaching the rock " (p. 265). He also 

 states that " there is frequently a 

 difference in the height of the peat on 

 opposite sides of the Canal, and con- 

 stant indications of the varying contour 

 of the old land-surfaces ; but it is evi- 

 dent that those of the rocky eminences 

 have been continuous with the lower 

 and upper beds of peat" (loc. cit.). 

 Having carefully watched the progress 

 of this section of the Canal, I can 

 testify to the accuracy of Mr. Morton's 

 observations. He has kindly allowed 

 me to make use of this section ; and 

 I am greatly indebted to him for this 

 favour, because it enables me to base 

 my explanations of the causes of sub- 

 merged Peat- and Porest-beds upon 

 his independent observations. How- 

 ever opposite, therefore, my conclu- 

 sions as to the causes of submerged 

 Peat- and Porest-beds may be to his, 

 there is no difference between us as 

 to the stratigraphical position or de- 

 scription of the section. 



The section of the Ship Canal from 

 EUesmere Port to Ince Perry is about 

 three miles long, and is cut through 

 marshes forming the left bank of the 

 Mersey, into which they drain. The 

 section exposes the solid basement upon 

 which the Grlacial and post-Glacial 

 beds repose. Mr. Morton gives the 

 following details of the section at 

 Ince Perry : —
