Udd drew his pictures in the snow again, while Shef, called into service as the argument grew heated, translated from English to Norse—Udd’s Norse had never reached the technical stage. Finally Herjolf sighed, and agreed to let Udd try. “It’s a blessing,” he remarked, “that this time he only wants something half the size of the last one.”
“A hammer is easier to lift than a mill-wheel,” Shef explained. “Udd says he is willing to start with only a light hammer.”
“How light?”
“A hundredweight.”
Herjolf shook his head and turned away. “Tell him to see Narfi Tyr’s priest, the chronicler, and ask him for vellum and a pen. His sketches will be easier to follow if they are in pen and ink, not drawn in the snow. Besides, if what he says is true, in time to come men will fight for a page of them.”
Soon, when the wind blew, the trip-hammer pounded, beating out metal at unheard of rates like the never-ceasing hammer of Völund, the lame smith of the gods.
It was Cwicca who was responsible for the next step. Not having a skilled trade, other than playing on the bagpipe and shooting a catapult, he was usually assigned to some repetitive task. One day, struggling with the leather bellows which provided forced draught to the forge, yelled at continually by the smiths not to stop or everything would be ruined, he stepped off the upper handle he had been working with his leg and shouted, “We need a machine to do this as well!”
Converting a trip-hammer to pump a bellows was almost easy. And yet the alteration brought about more change, as if one change was feeding off another. The very much improved flow of air through the ovens which smelted the finished ore raised the temperature very markedly. The smiths said iron went first blue-hot, when it was dangerous because you might put a hand on it without realizing, to red-hot, when it was soft enough to work. Only rarely had they seen iron white-hot, beginning to melt. Though cast-iron had been made, usually by accident and under especially lucky circumstances, the forced-draught bellows made molten iron for castings a possibility.
Underlying all the activity was the threat and fear, or certainty, of war. Shef had consulted Hagbarth and Narfi the priest of Tyr, and following his custom, tried to make a map of where he and his fellows had been. From all that they said, and from his own experience, he was in what looked very much like a trap, more of a trap even than the coast of Norway. From there, if he had had a ship, he could have sailed out into the open sea and tried to make the long passage to the Scottish shore, and then down the east coast to England. Where he was, even if he had free passage in Hagbarth’s Aurvendill, he would have to make his way out of the gulf between Sweden and the far shore of the Eastern Sea, where the Baits lived, then round Skaane and through the narrows between it and Danish Sjaelland to make his way home.
“How wide is the gap there?” he asked.
“Three miles,” said Hagbarth. “That’s how old King Kolfinn got rich. Levying tolls. Last I heard, he wasn’t likely to be there much longer. If you’re right about the Ragnarssons getting rid of Hrorik, there wouldn’t be too much left to stop them.”
“And where is their famous Braethraborg, the Stronghold of the Brothers?”
“There,” said Hagbarth, tapping the map at a spot on the north shore of Sjaelland maybe fifty miles from the narrows. Half a day’s sail.
The only other way back to England that Shef could see was to go back to Hedeby and walk across the marshes to the Ditmarsh, and so be back where he started. He would be once more without a ship. And anyway, if his vision was true, and it was confirmed by Hagbarth’s definite knowledge that the siege had started, then Hedeby was in enemy hands. Ragnarsson hands. Nothing anyone could imagine was worse than falling into Sigurth Ragnarsson’s hands. Shef would rather have died and been hung up in Echegorgun’s smokehouse.
