As these men have often their whole fortune at stake upon the burden of their mules, they have their weapons at hand, slung to their saddles, and ready to be snatched out for desperate defence; but their united numbers render them secure against petty bands of marauders, and the solitary bandolero, armed to the teeth, and mounted on his Andalusian steed, hovers about them, like a pirate about a merchant convoy, without daring to assault. The Spanish muleteer has an inexhaustible stock of songs and ballads, with which to beguile his incessant wayfaring. The airs are rude and simple, consisting of but few inflections. These he chants forth with a loud voice, and long, drawling cadence, seated sideways on his mule, who seems to listen with infinite gravity, and to keep time, with his paces, to the tune. The couplets thus chanted are often old traditional romances about the Moors, or some legend of a saint, or some love-ditty; or, what is still more frequent, some ballad about a bold contrabandista, or hardy bandolero, for the smuggler and the robber are poetical heroes among the common people of Spain. Often, the song of the muleteer is composed at the instant, and relates to some local scene, or some incident of the journey. This talent of singing and improvising is frequent in Spain, and is said to have been inherited from the Moors. There is something wildly pleasing in listening to these ditties among the rude and lonely scenes they illustrate; accompanied, as they are, by the occasional jingle of the mule-bell. It has a most picturesque effect also to meet a train of muleteers in some mountain-pass. First you hear the bells of the leading mules breaking with their simple melody the stillness of the airy height; or, perhaps, the voice of the muleteer admonishing some tardy or wandering animal, or chanting, at the full stretch of his lungs, some traditionary ballad. At length you see the mules slowly winding along the cragged defile, sometimes descending precipitous cliffs, so as to present themselves in full relief against the sky, sometimes toiling up the deep arid chasms below you. As they approach, you descry their gay decorations of worsted stuffs, tassels, and saddle-cloths, while, as they pass by, the ever ready trabuco, slung behind the packs and saddles, gives a hint of the insecurity of the road. The ancient kingdom of Granada, into which we were about to penetrate, is one of the most mountainous regions of Spain. Vast sierras, or chains of mountains, destitute of shrub or tree, and mottled with variegated marbles and granites, elevate their sunburnt summits against a deep-blue sky; yet in their rugged bosoms lie ingulfed verdant and fertile valleys, where the desert and the garden strive for mastery, and the very rock is, as it were, compelled to yield the fig, the orange, and the citron, and to blossom with the myrtle and the rose.
