Abstract
The deposits hereafter described occur at Little Heath, on the north-east side of the valley of the Bulbourne, near Berkhamsted, at 550 feet above sea-level and in latitude 51° 45′ 45″ N.; longitude 0° 31′ 30″ W. (See D on the map, p. 34.) They rest upon the Chalk of the extensive tableland, which, gradually rising towards the north, culminates at the scarp of the Chiltern Hills. This scarp hereabouts has an average height of about 700 feet, but rises at the Ivinghoe Beacon to 808 feet. The section to which attention is specially directed occurs in a pit that has been recently opened on Little Heath Common by the Heinel Hempstead Corporation, with the permission of Lord Brownlow, for obtaining supplies of road-metal. A generalized section of this pit shows the following beds in descending order:— Thickness in feet. 6. Surface-soil, with bleached Reading pebbles…bout 2 5. Pebbly clay and other glacial deposits, varying from 2 to 20 4. Stratified loamy sand 5 to 6 3. Stratified coarse gravel 17 2. Dark clay, with black-coated unworn flints and small well-rounded pebbles 6 inches 1. Chalk. No. 6. Surface-soil, with bleached Heading pebbles.—This appears to be made up of a portion of the underlying beds, which has become disintegrated. No. 5. The Glacial deposits.—These are somewhat
