These Moslem conquerors were admirable in their administration and development of the land they seized, quick to perceive its latent resources and make the most of them. Malaga itself became the court and seat of government of a powerful dynasty whose realms extended inland as far as Cordova, and the region around grew under their energetic and enlightened management into one great garden teeming with the most varied vegetation. What chiefly commended Malaga to the Moors was the beauty of its climate and the amazing fertility of the soil. The first was a God-sent gift, the latter made unstinting return for the labor freely but intelligently applied. Water was and still is the great need of those thirsty and nearly rainless southern lands, and the Moorish methods of irrigation, ample specimens of which still survive, were most elaborate and effective contrivances for distributing the fertilizing fluid. Many of these ancient systems of irrigation are still at work at Murcia, Valencia, Granada, and elsewhere. The Moors were masters of hydraulic science, which was never more widely or intelligently practiced than in the East. So the methods adopted and still seen in Spain have their Oriental prototypes and counterparts. They varied, of course, with the character of the district to be irrigated and the sources of supply. Where rivers and running water gave the material, it was conveyed in canals; one main trunk-line or artery supplied the fluid to innumerable smaller watercourses or veins, the _acequias_, which formed a reticulated network of minute ramifications. The great difficulty in the plains, and this was especially the case about Malaga, was to provide a proper fall, which was effected either by carrying the water to a higher level by an aqueduct, or sinking it below the surface in subterranean channels. Where the water had to be raised from underground, the simple pole, on which worked an arm or lever with a bucket, was used, the identical "shadoof" of the Nile; or the more elaborate water-wheel, the Arab _Anaoura_, a name still preserved in the Spanish _Noria_, one of which is figured in the Almeria washing-place, where it serves the gossiping _lavanderas_ at their work. In these norias the motive power is usually that of a patient ox, which works a revolving wheel, and so turns a second at right angles armed with jars or buckets. These descend in turn, coming up charged with water, which falls over into a reservoir or pipe, whence it flows to do its business below.
