It is rather more than amile in length and a third of a mile broad, the longer axis lying aboutnorth-east and south-west. Both extremities of the island are high, thenorth-east end forming a conical-shaped hiU 433 feet high, known as Pakihi Hill, while the centre is a low, fertile valley. The whole of the rocks found on the island belong to the UpperPalaeozoic period.* The north-eastern extremity is composed of hard blue and green sand-stones, brecciated in places, and much jointed, the fissiires of the jointsbeing filled with peroxide of iron. These sandstones dip about 40 W., andare overlaid by a series of soft, blue, sandy slates
