By candle-lighting time that day the storm had reached such a pitch and so mighty was the fury and noise raging across the top of Drangey, that Grettir and Illugi must needs put their lips to one another's ears when they spoke. There was no rain as yet, and the wind that held straight as an arrow's flight over the ocean, had blown away all mists and clouds, so that the atmosphere was of an ominous clearness, and the coasts of Iceland showed livid white against the purple black of the sky.
There were strange sounds about: the prolonged alarums of the gale; blast trumpeting to blast all through the hollow upper spaces of the air; the metallic slithering of the frozen grasses, writhing and tormented; the minute whistle of driving sand; the majestic diapason of the breakers, and the wild piping of bewildered sea-mews and black swans, as, helpless in the sudden gusts, they drove past, close overhead with slanted wings stretched tense and taut.
Towards evening Grettir and Illugi regained the hut, their bodies bent and inclined against the wind. They bore between them the carcass of a slaughtered sheep, the last on the island, for by now they had killed and eaten all of the herd, with the exception of one old ram, whom they had spared because of his tameness. This one followed the brothers about like a dog, and each night came to the door of the hut and butted against it till he was allowed to come in.
Earlier in the day Grettir, foreseeing that the weather would be hard, had sent Noise, the servant, to gather in a greater supply of drift. The thrall now met the brothers at the door of the hut, staggering under the weight of a great log. He threw his burden down at Grettir's feet and spoke surlily, for he was but little pleased with his lot:
"There be that which I hold will warm you enough. Hew it now yourself, for I am spent with the toil of getting it in on such a night as this."
But as Grettir heaved up the axe, Illugi sprang forward with a hand outstretched and a warning cry. He had glanced at the balk of drift, and had seen it to be one that Grettir had twice discarded, suspicious of the runes that he saw were cut into it. Even Noise had been warned and forbidden to bring it to the hut. Doubtless on this day the thrall had found it close by the foot of the ladder, and being too slothful and too ill-tempered to seek farther, had fetched it in despite of Grettir's commands.
"Brother," cried Illugi, "have a heed what ye do!"
But he spoke too late. Grettir hewed strong upon the balk, and the axe flipped from it and drave into his leg below the knee, so that the blade hung in the bone. Grettir flung down the axe, and staggered into the hut and sank upon the bed.
"Ill-luck is to us-ward," he cried, "and now wot I well that my death is upon me. For no good thing was this drift-timber sent thrice to us. Noise, evilly hast thou done, and ill hast thou served us. Go now and draw the ladder, and let thy faithful service henceforth make good the ill-turn thou hast done me to-day." And with the words the brothers drove him out into the night.
Grumbling, the thrall made his way to the ladder-head, and sat down cursing.
