Plate 4: Crater of Mount Schank. Part of the text accompanying the illustration reads 'Mount Schank is one of several extinct volcanoes situated at the South Eastern extremity of the Province of South Australia. In May 1844, I visted this remarkable district in company with His Excellency Governor Grey, and an exploring party. The crater of Mount Schank is a hollow truncated cone, of dark cellular lava; it is about 600 or 700 feet in altitude, and rises almost abruptly from a rich plain, scattered with luxuriant gum and wattle trees; the view from the rim, or outer edge of the crater is peculiarly striking; the neighbouring peaks of Mount Gambier ... rise in the distance on the one side ... whilst on the other, the Mouth of the Glenelg, the high land of Cape Nelson, and indentations of Bridge-water and Discovery Bay, with the Southern Ocean beyond, appear as on a map, over the opposite edge of the crater ... The accompanying sketch was taken in the early morning, and as I started betimes from our camp, I was the first to climb the mountain, stand alone on the edge of that vast crater, and to feel the thrill of pleasure which the grand and sudden panorama awakended. - This is one of the rewards of a traveller's toil'.
