_Segovia_ (7000), another of the picturesque cities of Spain, contains fine specimens of Roman, Moorish, and Christian mediaeval architecture in its wondrous aqueduct, cathedral, the Alcazar, and castle. It was formerly a place of great commercial as well as of political importance, and was the centre of a trade in woollen goods which employed 34,000 workmen, and made the cloth of Segovia celebrated throughout Europe. This commerce has now utterly departed, both from it and from the other cities, such as Avila, Medina del Campo, which shared its reputation. It is now visited by the lover of the picturesque, whose taste will be here abundantly gratified. Not far from Segovia, under the Penalarra (7800 feet), on the northern slope of the Guadarrama range, are La Granja and San Ildefonso. At a height of 4000 feet above the level of the sea, this is the most agreeable of all the inland royal residences of Spain. Built in French taste by Philip V., it is redeemed from banality by its pleasant surroundings. But retired and peaceful as it looks, La Granja has been the scene of some of the most important political events in the modern history of Spain. The celebrated passes of Somosierra (4700 feet), and that of the Col de Guadarrama (5000), lead from this province to Madrid; the railway, too, attains at La Canada a height of 4457 feet above the level of the sea. _Soria_, on the north-eastern edge of the great plateau, is one of the poorest provinces of Spain. Leaning on the Sierra de Moncayo, the whole of the northern and central part of the province slopes gradually to the west, and is watered by the Douro, which takes its rise in the Sierra de Moncayo. The southern angle of the province contains also the sources of the Jalon, which, flowing through a break in the Idubeda range, finds its way to the Ebro, and thence to the Mediterranean, the upper courses of the two rivers completely overlapping. In spite of these two river-valleys the province is very unproductive. Soria, near the site of the Keltiberean Numantia, which held out for twenty-nine years against the Romans, contains but 6000 inhabitants. Osma, on the Douro, has barely 1000, and Agreda (4000) is celebrated only for the visions of a nun in the sixteenth century.
