Excerpt from book: CHAPTER IL GENERAL VIEW OF THE CONTINENTS. 1. Direction of the forces that raised the continents. 2. Proportion of land and water; size of the continents and islands; outline of the land. 3. Extent of coasts, and proportion they bear to the areas of the continents. 4. Elevation of the continents. 5. Forms of mountains; direction of the chains of mountains. 6. Connection between physical geography of countries and their geological structure; analogies of the form and contour of countries. 7. Interruptions in continents and mountain-chains; table-lands and plaint. 1. At the end of the tertiary period the earth was much in the same state as it is at present with regard to the distribution of land and water. The preponderance of land in the northern hemisphere indicates a prodigious accumulation of internal energy under these latitudes at a very remote geological period. The forces that raised the two great continents above the deep, when viewed on a wide scale, must evidently have acted at right angles to one another, nearly parallel to the equator in the old continent, and in the direction of the meridian in the new; yet the structure of the opposite coasts of the Atlantic points at some connexion between the two. The mountains, from then rude and shattered condition, bear testimony to repeated violent convulsions similar to modern earthquakes; while the high table-lands, and that succession of terraces by which the continents sink down from their mountain ranges to the plains, to the ocean, and even below it, indicate also that the land must have been heaved up occasionally by slow and gentle pressure, such as appears now to be gradually elevating the coast of Scandinavia and other parts of the earth.
