Excerpt from Spain Nevada while the Picos de Europa in the Cantabrian Range attain over 8000 feet. The plateau itself is traversed by four mountain-ranges, the Oca and Idubeda Mountains above mentioned, which separate the valley of the Ebro from that of the Douro, the Guadarrama Range, which divides this river from the basin of the Tagus, the Sierra de Toledo, which forms the watershed between the Tagus and the Guadiana, while the southern but tress, the Sierra Morena, forms the northern wall of the valley of the Guadalquivir. The whole plateau has a general slight inclination from east or north-east to south-west, and hence all the con s'iderable rivers of Spain except the Ebro ¿ow west ward to the Atlantic. The general elevation of the plateau conceals the real height of its moun tains and passes, thus, the highest point of the railway from the north to Madrid is about 60 feet higher than the tunnel of Mont Cenis, and that of the old coach-road through the Guadarrama is 300 feet higher still. Geology - A mass of granitic, Cambrian, and Silurian rocks extends from Galicia south-east to the valley of the Guadalquivir. The Carbon iferous formation occupies the north and south west corners of the great plateau. The valley of the Ebro is a trough of Secondary rocks extend ing from the Bay of Biscay to the Mediterranean, another band of Secondar rocks forms the region of Andalusia south of the uadalquivir the Upper Cretaceous formation stretches from the basin of the Ebro to the granite of the Guadarrama and to the east of Madrid, these older formations are overlaid by Tertiary, Eocene and Miocene, marine and fresh-water deposits. The visible surface of Spain consists of 37 per cent. Of crystalline and Palaeozoic rocks, 34 per cent. Of Tertiary, 19 of Secondary rocks, and 10 per cent. Of Quaternary deposits. The remains of undoubted volcanoes are found at Clot in Catalonia, at Cabo de Gata in the south-east, and at Ciudad Real in La Mancha. To the frequency of older igneous action, and to the fractured condition of the later rocks, is perh due the great mineral wealth of Spain.
