by a fine bridge; it is here the traveller first sees in operation the _norias_ or water-wheels of the East. The kingdom of ARAGON contains three provinces, _Huesca_, _Saragossa_, and _Teruel_. The kingdom is almost bisected by the Ebro, towards which it slopes on both sides, from the highest summits of the Central Pyrenees on the north, and from the Idubeda Mountains and the Molina de Aragon on the south. Aragon divides with the Asturias the honour of having been one of the cradles of the Spanish monarchy. In 795 Don Asnar defeated the Moors near Jaca, in the province of Huesca. But the progress of the reconquest was very slow; from 714 to 1118 the Moors held possession of the town and kingdom of Saragossa, and it is from this occupation of four centuries that the traveller first meets here distinct remains of Moorish architecture. A still more lasting note of their sway is found in the nomenclature of the country. The rivers Guaticalema, Alcanadre, Guadalope, the names of the sierras, Alcubiere, and of many of the lesser towns and villages, sufficiently attest the former presence of the race who gave those names. _Huesca_ (10,000), the capital of the province of the same name, is an episcopal and university town, the bishop's palace being on the site of an old mosque. The upper part of this province is exceedingly mountainous, and is entered from France by the Central Pyrenean road, that of Somport, originally constructed by the Romans. The only other towns are Barbastro (7000), Monzon (4000), and Jaca (3500), nearer the mountains. _Saragossa_ (84,000), on the Ebro, formerly the Caesar Augusta of the Romans, then for four centuries the capital of a Moorish kingdom, rivals Santiago de Compostella as a place of pilgrimage to the shrine of the Virgen del Pilar. The worship has, however, much declined of late years, and her devotees are not now a tithe of those who frequent the more recent shrine of Notre Dame de Lourdes on the other side of the Pyrenees. The art treasures of the cathedral were sold in 1870, when many fine examples of jewellery and art were acquired for the Kensington Museum. Saragossa, though now fallen as a place of commerce, must again become important if the railway project is carried into effect, which will place it on the most direct line between Paris and Madrid. The Ebro, from its shallowness, is of no service for navigation; and, from neglect, the canals of Charles V. and of Tauste do not render the services they might, either for transport or for irrigation. Hence the despoblados and desiertos in the valley of the Ebro, both above and below the town. _Calayatud_ (12,000) was one of the four _comunidades_ of Aragon, and is in the midst of a mineral district, the wealth of which seems at present almost wholly undeveloped. _Teruel_ (7000) is the capital of a very mountainous province which slopes towards the north-west from the Sierras de Molina and Albarracin, the mountain
