She passed on, while the over-arching trees dropped lights and shadows across her face. Peter watched her till the blue distance of the forest closed round the cart, and the creaking of its wheels died into silence. He came back to a knowledge of himself with a rush. For the time being his mind had been merged in the mind of another. The forest, too, was waking as from a trance. Barbara had seemed to hold it in the spell of her own dreaming. Now the wind blew down the track, trundling dead leaves before it, and drawing a low chiming from the branches overhead. The birds burst into renewed twittering, and the rabbits leaped among the fern. CHAPTER IV THE SHIELD OF ACHILLES Barbara was driving sheep on the fells above Cringel Forest. She looked down and saw the trees bourgeoning into leaf, and rising out of them, on the top of a jutting crag, the old house belonging to Joel Hart. It was an unpretentious place, but battlemented and loop-holed, made for defence when moss-troopers paid frequent visits, and not for beauty or comfort. It was, in fact, little better than a fortified farm-house; underneath it ran a long dark cellar, where the cattle of the villagers could be driven for safety in times of alarm. Barbara's keen eyes--keen as an eagle's to scan the broad fellside--noted the air of decay which had settled upon it, the thicket of brambles among the chimneys, and how a pine, growing out of the rocks, encroached upon the doorway. Behind the house the ground swept steeply up, strewn with shattered boulders and weeping with waterfalls. "Poor Joel," she said to herself. "He's like Paris, in the book Peter gave me--beautiful Paris that Helen loved, whose soul ill-matched his fair form." She thought of her sister's adoration of this man, and was sad. There could be nothing but disappointment in store for Lucy, she felt sure of it, unless the girl overcame her affection and set her heart upon a more worthy object. But she was attracted by the glamour of fallen greatness, by his handsome presence, and she admired his pride. Barbara, with clearer vision, saw a man tossed about by circumstance, without a guiding principle in his life, whose pride was as hollow a thing as a soul ever cherished. She turned away from Forest Hall, and the disquieting thoughts which Joel roused, and looked up the dale. It wound in sun-swept greenness to Thundergay, where Swirtle Tarn glittered like a silver sixpence. For some days clouds had been gathering there, piled one on the other like wool-sacks, white and soft as wool just now, but stained crimson at sunrise, and black as smoke at night. The light was vivid, and had that peculiar quality of deepening the colours of the landscape, often the forerunner of storm; the purple of the distant hills was more intense, the green of the grass richer, the red of ploughed earth more passionate.
