Thus they travelled on, and on; descending steadily towards the bed of a torrent, whose course ran through the bottom of the valley. The path, though not very steep, was rugged and at times difficult to follow as it wound its way between rocks, stretches of barren, dusty ground, and yellow stubble. At long intervals a scraggy tree would raise its solitary head; lifeless, immovable in the breathless atmosphere, like some lonely hermit of the wilderness; its shadow falling athwart the sun-baked earth, like that of a little wandering cloud, lost and frightened in the great expanse of light its presence alone seems to mar. Occasionally the shrill note of a wild bird would issue from one of these oases of shade, only to die away instantly, choked and overpowered by the weight of the all-embracing silence. Big purple thistles, pink-belled convolvuluses, and lilac mallows, rearing themselves here and there in defiance of the sun, seemed only to enhance the general air of desolation; while below and above stretched endless lines of ancient grey stone-walls, covered with dry yellow moss. Fields of uncut grain, with spears like yellow pine-cones, closed in the distance. On, and on, they went. Giovanna's head was burning beneath her woollen kerchief upon which the sun's rays beat mercilessly; and big tears coursed silently down her cheeks. She tried to hide them from her mother, who was riding on the saddle, while she was seated on the crupper, but Aunt Bachissia heard, Aunt Bachissia saw, even out of the back of her head; and presently she could contain herself no longer. "Look here, my soul," said she suddenly, as they traversed the bottom of the valley, between great thickets of flowering oleanders; "will you have the goodness to stop? What are you crying for, anyhow? Haven't you known it for months and months?" Instead of stopping, however, Giovanna only burst forth into loud sobs. Aunt Bachissia glanced around; the others had all gone on ahead, and they were quite alone. "Haven't you known all along how it would be?" she repeated, in low, even tones that seemed to Giovanna to come from an immeasurable distance and, sweeping by them, to be swallowed up in the surrounding void. "Are you such a fool, my soul, as not to have known it from the first? Did he or did he not kill that infamous Vulture? If he killed him----" "But he never said he had done it!" interrupted Giovanna.
