Rh gradually less. This forms a very good example of the opposing fluviatile and marine geological agencies. This point was evidently a favourite camping ground for the Maoris, for many good examples of their stone implements have been found in the locality. On approaching the Green Island Bluff, the sand has encroached very considerably on the land, and caused a good deal of damage; but from this point for about 3 miles we find no dunes, as the coast is formed of cliffs composed of the Caversham sandstone, which is easily worn away by the beating of the waves, assisted in stormy weather by an irresistible volley of basaltic boulders derived from the easily fractured columns at the Green Island Bluff. At St. Clair we again meet with sandy deposits, which rise into hillocks of moderate height, and are especially interesting because among them are found, in great profusion, beautiful examples of sand-worn stones having that peculiar triangular section which is so familiar and striking. About this point a short portion of the beach has been attempted to be reclaimed, and on it a marine esplanade has been laid out, but recently unusually severe storms have washed away the retaining wall, and greatly damaged the appearance of the locality. From the western extremity to Lawyer's Head, a distance of two miles, are wonderful natural facilities for the construction of one of the most magnificent promenades that could be desired; but the sandhills are at present by no means pleasant to walk upon, and the space between high and low water-marks is alone available.

Opposite the tram terminus, the isthmus connecting the Peninsula with the mainland, is only about three-quarters of a mile in width, and Maori tradition relates that in old days this was covered at high water, and the tides met. Now, however, the high-water mark on the seaward side is very much further back than even a few years ago, and several lagoons have been formed. For a long way round the Peninsula, after leaving the Tomahawk lagoon, high cliffs have prevented any Æolian formation, and it is not until near the Sandymount district that deposits of this nature are again met with. The loose, drifting material is here carried up to an extraordinary height, and has given its name to the locality. In other places round the coast, large deposits of a similar nature are encountered, but only one of these, at the Maori Kaik, requires mention, and that on account
