[...] From the edge of the small cliff that now forms the seaward face of the exposure the rock slopes gradually upwards to the edge of the cultivated land and in places one can trace parallel lines of low ridges that closely resemble the successive strata of beach-sandstone in some of the Maldive islands. [...] The sandstone in this region exhibits a varying dip ; irk places the dip runs towards the sea while in others it is horizontal and in a few places the inshore part of the exposure shows a ' reverse ' slope the dip of the stratum being away from the sea with a slope of approximately i in In places the top level of the sandstone is actually higher than that of the general surface of the land and [...] Agassiz (1903a p. 232) from his experience of the Gilbert and Ellice Atolls of the Pacific Ocean concluded that ' in those districts where it is impossible or difficult to observe the structure of the underlying platform the coral reef question limits itself to the study of the cutting down of the reef platform and of the land rim of the movements of the mass of material which rests upon the u
