River, we have a well-marked line of elevation, to the east and west of which, at intervals, outliers of the Waipara beds are to be found. For example, to the west, in the Valley of the Eden, and in the Lower Conway, and thence extending a few miles inland from the Amuri Bluff to the coast at the mouth of Oaro Creek. Though at considerable distances, the limestones and saurian beds in the Kaikoura Peninsula west of the anticline, and the Waipara formation as exposed near the source of the Hapuka River, are evidently a continuation of this western division. At the Amuri Bluff only are any portions of the Waipara beds continuous, so as to connect the eastern and western wings of the anticline. On the east side none of the Waipara rocks appear south of the Conway River, while at the Kaikoura Peninsula the whole have been removed on the crown of the anticline to the underlying beds, while east of the source of the Hapuka River the Waipara beds are not present, the older rocks reaching to the sea level. They are, however, to be found on the right bank of the Clarence River, extending some distance south along the coast. To the east of this line of elevation the Waipara beds are nowhere observed to form a syncline (the Kaikoura Peninsula excepted), but on the west or inland side, this is invariably the rule. From the point where it crosses the Waiau, this same line of elevation may be traced south (a slight interruption occurring at Cheviot Hills), and still dividing the younger beds, as in the north, into an east and west division, the easterly seldom presenting a synclinal arrangement, the westerly invariably doing so. Further west, another belt of these younger rocks, often accompanied by tertiary beds, may be traced from Kaikoura up the valley of the Kahautara River, to the Upper Conway, thence across the Whale's Back to the Waiau Township, and at intervals along the borders of the Hurunui Plains, till, at the upper end of the Weka Pass, the two westerly divisions join. Tracing these south, they are found covering a considerable area in the vicinity of Heathstock, occurring as patches on the high ground dividing the south branch of the Waipara from the Okuku River, reported as occurring in the Upper Ashley, present in the Waimakariri basin west of Mount Torlesse, forming the coal basin west of the Big Ben Range, present in the Rakaia Valley near the mouth of the Acheron, crossing which at Redcliff they are next seen on the Smythe River, and at Clent Hills near Lake Heron. They are next seen in the Moorhouse Range on the north bank of the Rangitata, crossing which they appear in Coal Creek, and at Raincliff, west of Mount Four Peaks, uniting with the eastern division in the low country between Burke Pass and Timaru. These western divisions, in most cases,
