s, a coarse chalk gravel above and a fineyellow sand below, occupy the east end of the cutting and sink withit to the level of the next embankment. The embankment hides the junction between the Oxford andKimmeridge Clays, the next exposure, after an interval of 1188 ft.,being a dark, almost black clay slightly shaley, underlying the EedChalk. After dipping away out of sight, it reappears in the cuttingfurther east by a slight bend in an upward direction. It is probablythe Kimmeridge Clay, but characteristic fossils were not obtained. The Red Chalk is for the most part rubbly, hard and nodular, thelumps being often veined with a grey-green marking.

Above this comes the Grey and Lower White Chalk of the usualcharacters, but about 30 ft. above the true Eed Chalk there is apink band of about a foot thick resembling those at Speeton andLouth, Lincolnshire. A few irregular pale-coloured flints occur inthe Lower Chalk, and the joint surfaces are in many places black-ened by a deposit of manganese. Thin bands of Fullers Earth occurin the Lower Chalk. A remarkable set of beds of an argillaceousand carbonaceous character occurs in the White Chalk 25 ft. abovethe Pink Chalk above mentioned. The total thickness is abo
