The upper plain is here well defined (called Table Hills); its edge forms a
cliff or line of escarpment many miles in length, projecting over a lower
plain. The lowest plain corresponds with that at San Josef with the recent
shells on its surface. Between this lowest and the uppermost plain, there
is probably more than one step-formed terrace: several measurements show
the existence of the intermediate one of the height given in Diagram 1.

Near the north headland of the great Bay of St. George (100 miles south of
the Chupat), two well-marked plains of 250 and 330 feet were measured:
these are said to sweep round a great part of the Bay. At its south
headland, 120 miles distant from the north headland, the 250 feet plain was
again measured. In the middle of the bay, a higher plain was found at two
neighbouring places (Tilli Roads and C. Marques) to be 580 feet in height.
Above this plain, towards the interior, Mr. Stokes informs me that there
