PICTURESQUE DUNEDIN.

is gradually filled up in fine weather with a sandy barrier, through which the water finds its way, and which is destroyed by the first flood—we again meet with the basalt, this time descending to sea-level, and forming what is known as the Green Island Bluff—a picturesque headland, with fine examples of columnar structure, and forming a protection to the soft sandstone cliffs further on, of which, however, we can, from our present position, see nothing. Could we look over the top of the cliff, we should see very striking evidences of marine erosion, pinnacles and caves—one of the latter of considerable dimensions—with natural arches through which the green seas rush and swirl in their hungry efforts to devour the land. This elevated stretch of country is terminated at the Forbury Head by a sharp descent to sea-level, the base of the hill forming a charming site for the sheltered health-resort named St. Clair; and from this point the eye follows the ocean level along a line of sandhills to another basaltic promontory known as Lawyer's Head, which forms the commencement of the Otago Peninsula. It has been proposed, at this point, where the distance between the open sea and the waters of the harbour is but small, to cut a channel through the isthmus, and form a shorter and better entrance to the Dunedin wharves. At present the idea is not in great favour, but like other extensive public projects, it will no doubt return to popularity, and perhaps eventually be carried out. The Peninsula is a tract of land about 15 miles in length, formed principally of basaltic and trachytic rocks, and indented with several deep and sheltered bays. As our line of sight is necessarily straight across the harbour, looking due east, the nearer elevation of Signal Hill intervenes between our stand-point and Harbour Cone; but it is only when the greater height of Mount Cargill shuts out the distance, that we lose sight of the Peninsula. Still turning round, we pass the isolated peak of Mihiwaka, and following the coast, the character of which is indicated by several basaltic hills, we come again to the mica-schist hills of the interior. Merely stopping a moment to say good-bye to the beautiful panorama around us, we must descend to the flat, and resume our observations in a more detailed manner.

On this occasion it is best to commence some distance from the town, so with the reader's permission, we will take him to
