ranges which form the eastern boundary of the great watershed of the peninsula. Excepting the mines in these sierras, the province is almost wholly agricultural, but with no towns of importance. The historian Don Vicente de la Fuente has remarked that while the lands of the _comunidades_, the four free towns of Aragon, Calayatud, Teruel, Daroca, and Albarracin, have remained fertile under their more liberal government, the lands of the Seigneurs in the valley of the Ebro, where, almost alone in Spain, feudalism received its full development, have been for centuries barren and _despoblados_. [Illustration: LEANING TOWER OF SARAGOSSA. _Page 98._] CATALONIA.--The ancient principality of Catalonia is now separated into four provinces, named after their chief towns, _Gerona_, _Barcelona_, _Tarragona_, and _Lerida_. The first three lie along the shores of the Mediterranean--the last, inland, and stretches from the Ebro to the Pyrenees. To the north of Lerida, and buried in the mountains, is the so-called republic of Andorra, which owes its practical independence to the singular fact of a double _seigneurie_. Both the Counts of Foix, in France, and the Prince-Bishops of Urgel, in Spain, were supreme Lords of Andorra. On paper its constitution is by no means so free as that of several other Pyrenean communities; but by skilfully playing off the jealousies and rivalries of its two lords, and preventing either from getting absolute power, this little state of twenty-eight miles by twenty has remained unsubdued, and unattached to either nationality. The chief trade of the republic may be said to be smuggling. _Lerida_, except in the valley of the Segre, is extremely mountainous, and like all the hill country of Catalonia is rich in minerals, especially in salt, near Solsona. The rest of its products are chiefly agricultural. The province is but thinly peopled; its chief town contains 20,000 inhabitants. Balaguer (5000), Urgel (3000), Solsona (2500), are the most populous of the remaining. With _Gerona_ we enter the Mediterranean or Provencal region and climate, and come in contact not only with picturesque and glowing scenery, with a gorgeous variety of natural productions, but also with traditions and remains of the great works of all the races that have dominated this inland sea. From the Pyrenees to Carthagena the names of the chief towns recall classic reminiscences, and bring before us the struggles of ancient nations, contending on her soil for a far mightier empire than that of Spain. The province of Gerona contains Cape Creuz, the extreme north-easterly point of the peninsula, not far from the old Greek cities of Rosas and Emporium (Ampurias). Of its towns, Gerona, on the Ter, and Figueras have each 8000, but are surpassed by Olot, 10,000, around which town are grouped the most recently extinct volcanoes in Spain. Coal is found in San Juan de las Abadesas. Here the Spanish gravity is mingled with the fire and
