EXPLANATION OF THE PLATES.

Plate XVI. Vertical Clay Cliffs, TVhiteclff Bay, I. W. T. W. del. U l2.o J

This sketch represents a small portion of the cliff. The stream of water whichcomes down is one of several that have formed gullies that divide the cliff intoseparate parts. On the top of some of these, a horizontal stratum of gravel, eightor ten feet thick, lies in an unconformable position, shewing that the ends of thevertical strata must have been subjected to a considerable action before the gravelwas placed upon them. See page 120.

Plate XVII. No. 1. Whiteclijf Bay from Culver Cliff, I. W. T. W. del. f* ' ^^

This view was taken from the foot of the chalk cliff on the south side of the bay,from which the whole of it is seen. A is the bottom of the chalk cliff, the beds ofwhich are nearly vertical. The clay cliffs extend from B to C : I) is the curvedcalcareous rock represented on a larger scale in PI. XV., and may be traced fromthis place to E, at Bembridge ledge: F is the opposite coast of Hampshire. Seepage 120.

No. 2. Colwell Bay, and the Needles, I. W. T. W. del.

This view was sketched from the sea. The distance, under A, is part of the middlerange of chalk hills extending from the Needles to Freshwater gate. Under it, isthe middle of Colwell bay, where the strata dip in opposite directions. Under B, isthe north side of the hill called Headen, composed of freshwater strata alternatingwith those of marine formation. These cliffs are in a constant state of ruin : everywinter large masses fall down, and form terraces that reach into the sea: but it isvery diflicult to walk over them, on account of the quagmires made by the nume-rous springs. Beyond, at C, are seen the chalk cliffs of Alum bay with the Needles.See page 160.

No. 3. Alum Bay, and the Needles, I. W. T. W. del.

This view is also taken from the sea, to the west of Alum bay. Under A, is thewest side of Headen, where the alternating series of freshwater and marine strataare best seen. At B, is the curved part of the lower freshwater strata which comeup against the vertical clay and sand strata of Alum bay that extend from B to C :at C the chalk begins, and reaches to the Needles. Here are seen the projectionson the chalk cliff like buttresses. The distance, over C, is Freshwater down.D is the Lighthouse. Under F, G, II, are the three detached masses of chalkcalled the Needles. At E, is the perforation, or natural arch, in the extremity ofthe cliff. See pages 157, 163.
