The arrows represent the direction of the effluent currents as the land emerged 
from beneath the waters, leaving portions of the fine sediment on the plateaux, but 
sweeping it off the slopes and down the valleys. 
Jersey .—In this island there are the remains of a low-level Raised beach at Fort 
Regent, St. Clements, La Motte, Mont Orgueil, Ann’s Port, St. Catherine’s Bay, 
Rozel Bay, and Boulay Bay,* They are covered as in Guernsey by a rubble-drift or 
“Head,” and are about 5 to 15 feet above the sea-level.t They are well seen 
at Ann’s Port and St. Catherine’s Bay; the section at the former place is as under.

a. “Head,” largely composed of loam roughly bedded, with fragments, and a few angular blocks, of 
the rocks from the hills above, 12 feet. 
c. Raised beach, chiefly of diorite pebbles, 2 feet. R. Diorite rock. 
In none of these beaches have there been found any pebbles of foreign origin, with 
the exception of fragments of chalk flints, as in the beaches on the Devon and 
Cornish coasts ; nor did I see any shells, nor have any been recorded, except by Mr. 
T. W. Danby, who discovered in a Raised Beach on the Hermitage Rock, St. Aubyn’s 
Bay, “ an abundance of shells of species now flourishing on the adjacent shore.” The 
Beach, which was about 6 feet above high water mark, has since been concealed by the 
harbour works,In Jersey, as in Guernsey, brick-earth or Loess is widely spread 
* Professor Noury mentions besides, Portelet Bay, Crabbe, Petit Port (Vicard) : he assigns a different 
origin to the beaches, ‘ Geologic de Jersey,’ p. 162, 1886. 
t Dr. Dtjnlop informs me that there are some beaches considerably higher, but these I have not seen.
