    The Elland Flagstone is a fine-grained sandstone, which can sometimes be split into thin slabs. Chapeltown, Potter- newton, Buslingthorpe, Gledhow, and Harehills are on this rock. It forms steep escarpments at Headingley, and on both sides of Woodhouse Ridge. It is extensively worked at Potternewton, formerly at Woodhouse and Buslingthorpe. It extends towards the east as far as Roundhay Park, where it is faulted against Millstone Grit to the north, and against the shales above the Black Bed Coal to the east. The 20 feet sandstone is a poor, shafey rock, which is seen in the steep slope over the stream in Batty’s Wood, and forms a slight feature on the other side of the Mean wood Beck. The Ganister is worked in quarries in the Meanwood Valley. It is a white, fine-grained stone, with Stigmaria, Calamites and other plant-remains. There is a thin seam of coal in it. This rock, after having been crushed to a fine powder, is used for the hearths and roofs of regenerative furnaces. It is extremely hard, and weathers with difficulty. As we go up the Meanwood Valley we come to measures lower and lower in the series ; this is because the rocks dip roughly S.E. Thus at Buslingthorpe we have the base of the Elland Flagstone only 175 feet above sea-level, while at Miles Hill, about a mile further up, it is 360 feet above it. At Buslingthorpe the bed of the stream is formed by the shale below the Elland Flagstone, and at Meanwood Tannery by the shale under the Ganister. Northern Area. In the northern portion we find the following measures :— (about) 60 feet. (about) 100 feet, (about) 50 feet. 4 inches. 50 feet. 3 inches. Middle Grits, 20 feet. D
