Book excerpt: Excerpt from Memoirs of the Geological Survey of Great Britain and of the Museum of Practical Geology: The Geology of East Lothian, Including Parts of the Counties of Edinburgn and Berwick (Maps 33, 34,& 41) The area represented by the present Map contains about 378 square miles. It embraces nearly the whole of Haddingtonshire (or East Lothian), with the eastern parts of Edinburghshire (or Mid Lothian), and the northern borders of Berwickshire. A line drawn from the south-west to the north-east comer of the sheet divides the district into two nearly equal but very distinct portions, and this line, running along the flank of the Lammennuir Hills, will be afterwards seen to correspond with the trend of a long north-easterly fault. The north-western half is for the most part a low-lying rich agricultural tract of country. It rises, iudced, into one cluster of hills, known as the Garltons, between Haddington and the sea ; but as these nowhere reach a height of 600 feet, and as they are conscious of various felspathic rocks giving rise to a rich soil, they do not interfere with the generally fertile agricultural character of the district. With the exception of the tract covered by the G oil ton Hills and their neighbouring igneous masses, such as Trap-raiu Law and North-Berwick Law, the ground undulates gently from the flank of the Lammennuir chain towards the Firth of Forth. The volley8 arc little more than long confluent hollows, which range on the whole from south-west to north-cast. This feature is especially to be seen among the ridges of the Garltons. There the sheets of felspathie trap, having a general low westerly dip, are channelled into long troughs, gullies, or gentler depressions, running in tho direction just named. These hollows sometimes run along the hill-tops and are often quite dry, save of course in wet weather, wheu they serve as channels for the rain. They everywhere give evidence by that peculiar worn, rounded, and flowing outline, that they have suffered from the abrading agencies of the glacial period, and that the ice which smoothed them must have moved from west to east. In this lowland half of the district there is only one main stream, the Tyne, which rises in the south-west corner, near the end of the Lnm-raermuir chain, and after flowing to the north-east parallel to theso hills enters the sea u little to the west of Dunbar. This river receives the north-western drainage of the Lammermuirs and the brooks flowing from the southern and eastern sides of the Garltons, Hence only a few small rivulets are needed to carry oil' the drainage towards the sea on the north-west. The other or south-eastern half of the district presents a totally different aspect, and the line between it and the agricultural plains just described is almost as sharply marked off as the corresponding boundary between the geological colours on the map. To the south-east of the rich champagne tract, the Lammennuir Ilills rise steeply iulo a line of bare, smooth, green, or heathy heights.
