Raised Beaches. 



85 



The members started from the mill-pond at the Vrangue, 

 and proceeded to the Capelles, and there inspected a section of 

 a " Raised Beach," which has been exposed to view in the 

 process of lowering the road running north from the school- 

 yard. Part of the open school-yard itself appears to be on an 

 ancient beach, while in another part the rock is seen. The 

 section visible on both sides of the road is not an extensive one, 

 nor is the deposit deep ; the elevation is about thirty feet from 

 the present high water mark, and distant from the nearest 

 coast one mile, although before the works of reclamation 

 carried out under Sir John Doyle, the tidal waters approached 

 to within a quarter of a mile of the spot. 



Thence the party proceeded to an abandoned quarry to 

 the eastward, where is the usual pond, which afforded a most 

 interesting supply of water-beetles, larvae of dragon -flies, 

 caddis-fly cases, water-snails, and in its immediate neighbour- 

 hood several good specimens of tiger-beetles were captured. 



Thence to the head of Grand Havre, where the short herb- 

 age yielded some fresh botanical specimens. Rosa Spinosissima, 

 Silene Conica, etc. Then on to the tongue of land dividing 

 Grand Havre from L'Ancresse Bay. On either side of this 

 peninsula is a hill rising about twenty-five feet above high 

 water mark. Between the hills is a slight hollow along which 

 lies the roadway. The hill on the right (north-east) yields fine 

 masses of first class granite. Mr. Bisson who owns the quarry 

 has cut several road-ways into it. Each of these several road- 

 ways slopes down into the various workings, cutting through, 

 and exposing to view a section, of an ancient beach, a mass 

 about four feet in thickness, consisting of water- worn pebbles 

 of moderate size, and larger masses of rock smoothed and 

 hollowed by the action of the waves and moving shingle. It 

 rests on the native rock, and spreads upward, gradually be- 

 coming thinner, a slight trace of it being visible under the soil 

 almost to the summit of the hill. The main deposit is probably
