Moulin Htjet.

In the first week of January, 1884, a visit was made to the 

 mine-workings at Mount Durant, Moulin Huet. Under the 

 able guidance of Mr. De Carteret, who brought a ladder and 

 ropes for the occasion ; a small party including two ladies 

 descended to the beach at low water, after a rough descent over 

 a serrated vertical ridge of rock to the eastward of the mine. 

 Similar wall-like ridges form a conspicuous feature in the 

 scenery of this portion of the coast. The visitors were then 

 able to walk into the cave above which the workings were 

 carried on. The lower storey of the cave runs back some dis- 

 tance into the rock, and terminates in a wall which was built 

 some forty years ago, upon the complaint of the proprietor of 

 the adjoining estate that his well had been drained by the 

 mine-workings. This wall, it was supposed, would completely 

 dam back the water, but now a copious stream makes its way 

 through, running over the face of the wall and through the 

 cave, leaving an abundant ferruginous deposit. In the roof of 

 the cave is an opening, through which access is had to a second 

 gallery, also penetrating into the face of the ciiff, and there 

 appears to be a third gallery above. Here, in the roof of the 

 lower division of the cave, and above it, is an extensive deposit 

 of large boulders, and at the innermost part, of smaller pebbles 

 and sand completely filling up the recesses of the second storey. 

 The whole is evidently part of an ancient sea-beach, distin- 

 guished by the large boulders. In elevation, the deposit cor- 

 responds very nearly with the cave at Icart, and with some of 

 the pebbles in the walls of the cave close to the eastern side of 

 the slip forming the usual approach to the beach at Moulin 

 Huet, and must have been formed when the sea was at a 

 higher level than at present. 



Other observers have noticed similar raised beaches in 

 other parts : Professor Ansted notices one in the island of 

 Lihou, another near the cliffs at Havelet ; also in the island of 

 Brechou, in Alderney, and in Jersey. I am unaware of the
