The history of Barbados [electronic resource] : comprising a geographical and statistical description of the island, a sketch of the historical events since the settlement and an account of its geology and natural productions . from thesummit to their present situation. The fragments are calcareous, some-times of the size of a pigeons egg, rounded, seldom angular, and smooth.At Whoop Gully below the sandstone is gritty clay, which is frequentlyaluminous, and lies in horizontal strata. On the eastern declivity of Chalky Mount, where that mountain front*the sea, the strata are apparently much-contorted and twisted; this ischiefly the case where the light-coloured friable sandstone is in contactwith a calcareous sandstone containing minute specks of mica; ferrugi-nous sandstone and compact iron ochre rest upon it. The calcareoussandstone is twisted in a most remarkable manner. comminuted shells and triturated calcareous matter, the latter of siliceous parade*or properly speaking, sand : this difference in their nature arises obviously froBthe relation of the adjacent land from whence the sands were washed down.1 See ante. p. L^J-l. GEOLOGICAL DESCRIPTION. Fig* U, —View of the eastern part of Chalky Mount, 519. In the neighbourhood of these sandstones, on the north-eastern pointof Chalky Mount, is a seam about ten feet in width of fragments ofcompact gray limestone, coated with calc-spar. Spheroidal concretions, varying from the size, of a pigeons egg to three feet in diameter, anddivided into cells and chambers of irregular form, are found among theserocks- They are Septaria, composed of argillo-femiginous luuestone, intersected by veins of calc-spar1. The strata of sandstone which thisseam traverses, dip at a high angle to the south-south-east, the directionbeing west-south-west, I found here likewise a nodule coated by uiani-inillar compact lime resembling Aragonite. The ferruginous fine-grained sandstone (almost red in colour) assumes aslaty structure on the south-ea
