"The bane of Grettir," answered the witch, and with that she crouched herself down by the log and cut runes upon it. Then she stood upright and walked backwards about the log, and went widdershins around it, and then, after carving more runes, bade Thorbjorn cast it into the sea.
The Hook scoffed and jeered, but, mindful of his oath, set the log adrift. Now the flood tide made strongly at the time, and the wind set from off the ocean.
"It will come to shore," he said.
"Ay, that I hope," said the witch; "to the shore of Drangey."
On the beaches, where the torn scum and froth of the waves shuddered and tumbled to and fro in the wind, The Hook and the old witch stood watching. Thrice the surf flung the log landward, thrice the undertow sucked it back. It was carried under the curve of a great hissing comber, disappeared, then rose dripping on the far side. The hag, bent upon her crutch, her toothless jaws fumbling and working, her gray hair streaming in the wind, fixed a glittering eye, malevolent, iniquitous, far out to sea where Drangey showed itself, a block of misty blue over the horizon's edge.
"A strong spell for a strong man," she muttered, "and an ill curse for an evil deed. Blighted be the breasts that sucked ye, and black and bitter the bread ye cat. Look thou now, foster-son," she cried, raising her voice.
The Hook crossed himself, and his head crouched fearfully between his shoulders. Under his bent brows the glance of him shot uneasily from side to side.
"A bad business," he whispered, and he trembled as he spoke. For the log was riding the waves like a skiff, headed seawards, making way against tide and wind, veering now east, now west, but in the main working steadily toward Drangey. "A bad business, and peril of thy life is toward if the deed thou hast done this day be told of at Thingvalla."
