Abstract
1.General Description. Alderney is seldom visited and has been seldom described. It deserves both description and visit. Macculloch gives an account of it in the first paper of the first volume of our ' Transactions.' Ansted,in his ' Channel Islands,' notices many features with accuracy, and seems to have taken a special interest in the place. Since his time I am not aware of a single addition to our knowledge until theadmirable map of France by MM. Vasseur and Carez, sheet No. IV.N.E. of which assigns colours and letters to the island. After the first draft of this paper had been written, a paper by M. Bigot * came into my hands, containing, besides notes on Jersey and Guernsey, a brief but excellent description of Alderney, which includes several of the facts that I have independently discovered. I have to thank Professor Bonney for invaluable notes on the rock-sections, which he has allowed me to incorporate in this paper. Alderney is an oval island (see: Map, p. 381 † ), about 3½ miles long by 1 mile broad, lying E.N.E. to W.S.W. The western portion is a tableland just over 300 feet in height, which, along the west and south, falls in grand cliffs to the sea, but slopes to the shore along the north-western side. The eastern extremity is separated from this by lower ground and the deep indentation of Longy Bay, but above the Mannez Qualwy and at Fort Albert there are elevation of 140 feet and 180 feet respectively.This publication has 0 references indexed in Scilit:
