She fell slightly behind the others, without being noticed. Then quite abruptly a stone turned under her foot, and she fell headlong, striking her head violently against a second stone. Then she lay quite still while the red cloud billowed slowly toward her, drifting gently in the faint, hardly perceptible breeze. It drew nearer and nearer, settling slowly, but still a huge and menacing mass of deadly dust. It gradually flattened out, too, so that though it had been a rounded cone at first, it flowed over the minor inequalities of the ground as a huge and tenuous leech might have crawled, sucking from all breathing creatures the life they had within them. A hundred and fifty yards away, a hundred yards away, then only fifty yards away. From where Saya lay unconscious on the earth, eddies within the moving mass could be seen, and the edges took on a striated appearance, telling of the curling of the dust wreaths in the larger mass of deadly powder. The deliberate advance kept on, seeming almost purposeful. It would have seemed possible to draw from the unhurried, menacing movement of the poisonous stuff that some malign intelligence was concealed in it, that it was, in fact, a living creature. But when the misty edges of the cloud were no more than twenty-five yards from Saya's prostrate body a breeze from one side sprang up--a vagrant, fitful little breeze, that first halted the red cloud and threw it into confusion and then drove it to one side, so that it passed Saya without harming her, though a single trailing wisp of dark-red mist floated very close to her. Then for a time Saya lay still indeed, only her breast rising and falling gently with faint and irregular breaths. Her head had struck a sharp-edged stone in her fall, and a tiny pool of sticky red had gathered from the wound. Perhaps thirty feet from where she lay, three small toadstools grew in a little clump, their bases so close together that they seemed but one. From between two of them, however, just where they parted, twin tufts of reddish threads appeared, twinkling back and forth, and in and out. As if they had given some reassuring sign, two slender antennæ followed, then bulging eyes, and then a small black body which had bright-red scalloped markings upon the wing-cases. It was a tiny beetle no more than eight inches long--a burying-beetle. It drew near Saya's body and clambered upon her, explored the ground by her side, moving all the time in feverish haste, and at last dived into the ground beneath her shoulder, casting back a little shower of hastily dug earth as it disappeared.
