In the meantime Grettir, Illugi, and the churl Glaum were on Drangey catching fish and fowl for winter supplies. The fish in Iceland are beaten hard with stones and then dried in the wind, that makes them like leather; but it preserves them for a very long time, and they form the staple of food, as the people have no corn, and consequently no bread. They put butter on these dry fish, and tear them with their teeth. What Grettir did with the fowl he caught was to pickle them with salt water from the sea, and when the frost and snow came on then he would take them out of pickle and freeze them. Now, the whole of the sheep had been eaten some time ago, except the old mottled ram, which Grettir could not find in his heart to kill; and, as may be supposed, he and his brother suffered from want of change of food. Especially deficient were they in any green food; and we know, though he did not, that the eating of green food is a very essential element of health. He had nothing for consumption but salted birds and dried fish—no milk, no bread, no vegetables. Such a diet was certain to disorder his health.
The day after that on which the hag had charmed the piece of timber, the two brothers were walking on the little strand to the west of the island looking for drift-wood.
"Here is a fine beam!" exclaimed Illugi. "Help me to lift it on to my shoulder, and I will carry it up the ladder."
Grettir spurned the log with his foot, saying, "I do not like the looks of it, Little brother. Runes are cut on it, and what they portend I do not know. There may be written there something that may bring ill. Who can tell but this log may have been sent with ill wishes against us." They set the log adrift, and Grettir warned his brother not to bring it to their fire.
In the evening they returned to their cabin, and nothing was said about the log to Glaum. Next day they found the same beam washed up not far from the foot of the ladder. Grettir was dissatisfied, and again he thrust it from the shore, saying that he hoped they had seen the last of it, and that the stream and tide would catch it and waft it elsewhere. And now the equinoctial gales began to rage. The fine Martinmas summer was over. The weather changed to storm and rain; and so bad was it that the three men remained indoors till their supply of firewood was exhausted.
Then Grettir ordered the thrall to search the shore for fuel. Glaum started up with an angry remonstrance that the weather was not such as a dog should be turned out in, with unreason, not considering that a fire was as necessary to him as to his master. He went to the ladder, crawled down it, and found the same beam cast at its very foot.
Glad not to have to go far in his search, Glaum shouldered the log, crept up the ladder, bore it to the hut, and throwing open the door, cast it down in the midst.
Grettir jumped up, "Well done," said he, "you have been quick in your quest."
"Now I have brought it, you must chop it up," said Glaum. "I have done my part."
Grettir took his axe. The fire was low and wanted replenishing, and without paying much attention to the log, he swung his axe and brought it down on the log. But the wood was wet and greasy with sea-weed, and the axe slipped, glanced off the beam, and cut into Grettir's leg below the knee, on the shin, with such force that it stuck in the bone.
