It may be, as a French writer states, impossible to tickle the surface of Granada without discovering Moorish remains, but certainly, outside the Alhambra, very few are to be seen above ground. The most conspicuous of them in the lower town is, on the whole, the Casa del Carbon, a dilapidated structure with a bold horseshoe archway which confronts you as you cross the Reyes Catolicos near the Post Office. The house is now used as a coal depot, but beneath the thick coating of grime you may discern the traces of graceful decorative work. The building is said to have been a corn exchange in Moorish days. More interesting are the vestiges of the ancient walls that girdled the oldest quarter, _el viejo Albaicin_. They were built in great part by Christian captives--perhaps by those whose chains are hung up on the walls of San Juan de los Reyes at Toledo. The Moors of Granada grew embittered by their reverses, and treated their Christian subjects harshly. The martyrs whom the monument on the Alhambra hill commemorates are not merely the creatures of pious imagination. There is an ugly story, too, of an unfortunate monk accused of heretical doctrines, who took refuge at Granada and was burnt at the stake by the Moslems. Two of the old gatehouses on this side of the city are still standing. They are massive crenellated towers, pierced with round-headed archways. I do not consider them entrancingly picturesque; they form the northern entrances to the Albaicin quarter, which is now a perplexing congeries of squalid houses, formless convents, and churches tottering to their fall. Whatever interest its antiquity may excite is lost in disgust at its wretchedness. On the outskirts dwell the gipsies--mostly in semi-underground burrows, and left very much to themselves by the local authority. These are the poor creatures who are dragged out to bore visitors with their wearisome dances, the fee charged for which goes almost entirely into the pockets of the guides. The gipsies of Spain are not nomadic. There are people in Granada who wish they were. [Illustration: GRANADA--CASA DEL CARBON]
