1916.] THE PLEISTOCEXE PERIOD. 345 



Alderney, Brechou, Herm and Jethou (see Photograph 

 No. 1, etc.) also have this beach well represented, and these 

 deposits may be passed by with the remark that the South 

 of Alderney is almost bare, that the West of Jethou is 

 without exposed beaches, these, if deposited, being hidden 

 by enormous blocks of stone. 



THE 50ft. DEPOSITS. 



Well inland are beach deposits of a different elevation. 

 These are fairly numerous, but not all the deposits can be 

 called beaches, some being but small remnants. Taking the 

 beaches first and in order of importance, I chose the beach 

 at the Cape'les as the largest for description. This deposit 

 extended at the time of its deposition from the Capelles to 

 Les Maingy resting on the Anneville hill. The whole beach 

 was thus the margin of a bay as large as Grand Havre, facing 

 north. The sands of that -bay still exist in situ. This 

 deposit has a mean depth of 5 feet, and is very flat at the 

 Capelles as though all irregularities had been eroded away. 



The next in importance is at Hougue Noirmont south of 

 Miellette Bay. Here we have a very extensive beach 

 extending to Rue des Chapelles and Hougue de Paradis. This 

 deposit is important because it demonstrates the order in 

 time of other deposits to be discussed later. The smaller 

 deposits are to be found on the tops of isolated hougues. Of 

 these, I shall name Noirmont Lane (probably a connecting- 

 link between Boque Maingy and the first named deposit) ; 

 there are three separate deposits, Noirmont Lane, La Moye 

 and Mont diet. These deposits are at wide distances apart 

 and cannot be associated with the 25-feet beaches. 



There are twelve well marked deposits in all. These 

 range in height from 46 to 65 feet with a mean elevation of 

 54 feet. For ease of reference the level is referred to as 

 " the 50-feet." 



In Jersey this level is represented by deposit at an 

 elevation of 60 feet. 



It is not necessary for my purpose that I should discuss 

 more fully the indications of this level in the smaller islands, 

 but I must call attention to the fact that it is traceable on the 

 coast of England ; I shall be satisfied with one example. 

 Both Godwin-Austin and Professor Prestwich (Trans. Geo. 

 Soc. 2nd Series, vol. vi., p. 441 and Trans. Geo. Soc. 1892, fol. 

 279), describe a'high level beach at Hopes Nose, near Torquay. 

 Its height is 31 feet above high-water mark. Allowing 

 15 feet for the difference to O.D. we have 46 feet, and
