bare of vegetation. At Hastings, the high ground has certainly receded, as, before the Castle Hill was cut back to make room for Pelham Crescent, part of the wall of the castle projected beyond the face of the cliff, and a large mass which had fallen off lay below at the foot of the hill; but the cliffs between Winchelsea and Pevensey are of too compact a structure to be easily acted upon by the sea, and they are probably now but little reduced from the appearance they presented at the time of Csesar's invasion. Beyond Hastings, towards Beachy Head, I am unable to point out any particular alterations ; there is some evidence of changes, in mediaeval times, near Pevensey, either on the shore or about the mouths of the streams, but I have no precise knowledge of the history of this locality. Throughout the line of coast here referred to, from Dover to Beachy Head, the beach is now drifted by the tide along the shore with considerable force, and is accumulating in various places, but this kind of deposit seems to be of comparatively recent origin, for the older parts of the low lands consist (so far as my knowledge of them extends) of mud and sand; this shows that the current is now stronger, at least along the low parts of the shore, than it formerly was,—a change probably caused by the wearing away of the cliffs and headlands. 
   We may now give attention to Caesar's operations. His first expedition appears to have been in some degree experimental, as it was undertaken late in the season, with a small force of two legions, unprovided with the usual quantity of baggage; and as the transporting of this body of troops seems to have required all the ships then at his command, he cannot be supposed to have contemplated at that time effecting a permanent conquest; and he says that if he could proceed so far only as to ascertain the character of the island and its inhabitants, the gaining of this information would be
