The rock for ale, no elevation in the interior, on the NW line traversed by the Expedition, was seen; but on the Stony Desert the fragments of rock, hich it was covered, were composed of indurated quartz, rounded by attrition, and coated with oxide of iron North of the Stony Desert, sandstone occurred in the bed of Eyre's Creek, and rees 35 rees 39 minutes The valley of Cooper's Creek was, however, bounded in by low quartzose hills, covered with sand The general level of the interior was otherwise ferruginous clay, on which the long sandy doones or ridges rested, excepting where their regularity was broken by flooded plains The clay rested on sandstone, which, with a few exceptions, where fossil tertiary limestone occurred, siinous sandstone, at the depth of two feet and a half or three feet
