Now, looking abroad over the earth, it appeared to Martin that the thousands and tens and hundreds of thousands of fragments of mist, had the shapes of men, and were like an innumerable multitude of gigantic men with shining white faces and shining golden hair and long cloud-like robes of a pearly grey colour, that trailed on the earth as they moved. They were like a vast army covering the whole earth, all with their faces set towards the west, all moving swiftly and smoothly on towards the west. And he saw that every one held his robes to his breast with his left hand, and that in his right hand, raised to the level of his head, he carried a strange object. This object was a shell--a big sea-shell of a golden yellow colour with curved pink lips; and very soon one of the mist people came near him, and as he passed by the rock he held the shell to Martin's ear, and it sounded in his ear--a low, deep murmur as of waves breaking on a long shingled beach, and Martin knew, though no word was spoken to him, that it was the sound of the sea, and tears of delight came to his eyes, and at the same time his heart was sick and sad with longing for the sea. Again and again, until the whole vast multitude of the mist people had gone by, a shell was held to his ear; and when they were all gone, when he had watched them fade like a white cloud over the plain, and float away and disappear in the blue sky, he sat down on the rock and cried with the desire that was in him. When his mother found him with traces of tears on his cheeks; and he was silent when she spoke to him, and had a strange look in his eyes as if they were gazing at some distant object, she was angrier than ever with the sea, for she knew that the thought of it had returned to him and that it would be harder than ever to keep him. One morning on waking he found her still asleep, although the traces of tears on her cheeks showed that she had been awake and crying during the night. "Ah, now I know why she cries every morning," thought Martin; "it is because I must go away and leave her alone on the hills." He was out of her arms and dressed in a very few moments, moving very softly lest she should wake; but though he knew that if she awoke she would not let him go, he could not leave her without saying good-bye. And so coming near he stooped over her and very gently kissed her soft cheek and sweet mouth and murmured, "Good-bye, sweet mother." Then, very cautiously, like a shy, little wild animal he stole out of the cavern. Once outside, in the early morning light, he started running as fast as he could, jumping from stone to stone in the rough places, and scrambling through the dew-laden bushes and creepers, until, hot and panting, he arrived down at the very foot of the hill.
