Just before reaching the Humber, the "Crane" stopped at a small river for fresh water. There were no habitations in sight, so Sigurd and Astrid went ashore while the casks were being filled.
"It is good to be on land again, Sigurd!" cried Astrid, after racing and beating him to the top of a small hill.
"I've been at sea so long that I don't notice it much," laughed Sigurd spreading his fur cloak in the snow for Astrid to sit on.
As they rested, looking over the broad expanse of snow, dotted with trees and forests that spread inland, they heard the ringing call of a war-horn from the ships.
"Come on, Astrid!" cried Sigurd, starting up, "something must be wrong at the ships!"
CHAPTER XIII.
ALFRED OF MERCIA.
THEY dashed down the hill, and in a few minutes were through the trees and on the river bank. They found Biorn drawing up his men.
"Why, what's the matter, Biorn?"
"I am not sure, Jarl, but look up the ice yonder."
He pointed up the frozen bed of the little river, and Sigurd saw a large party of armed men, pulling a sledge, running toward them. Sigurd examined them for a minute.
"I don't think they mean to attack us, Biorn, or they would not have that sledge. They look like Saxons, so best be ready."
By this time more men had arrived from the ships, and as the Saxons approached, Sigurd saw that there were some fifty men in the party. Finding the Northmen waiting, they stopped running, and one, better dressed than the rest, in a bearskin mantle and helmet, hastened on.
As he came near, Astrid said, "Why, Sigurd, he isn't any older than you are! And you were afraid of him!"
Sigurd made no reply save a smile, for, indeed, the Saxon was only a youth, but a noble-looking one. Nearly as tall as Sigurd, he was not so broad, but his face was frank,, and attracted the young Jarl at once.
"Are you Danes or Norsemen?" called the stranger.
"Norsemen," answered Sigurd, "and you are Saxons, I take it."
"Right you are," laughed the boy, with a glance over his shoulder. "Are you plundering the country?"
"Nay," answered Sigurd. "We are Christians. Bid your men stand back, for our arrows lie loosely on the strings."
The boy laughed again, as if it were a good joke, and turning, waved to his men, who halted.
"Let me explain," he said. "I am Alfred, son of Jarl Alfric of Mercia, and with me is Sigrid my sister. Briefly, we are flying from the men of King Ethelred; will you assist us?"
Sigurd, suspecting a trap, looked keenly at the boy; but his gaze was met squarely, and Sigurd's suspicions vanished. "Where is your sister, and your pursuers?" he asked.
Alfred pointed to the sledge. "My sister is ill, and we have to carry her." His face suddenly became serious. "Hasten your reply, sir Norseman, for God's sake! The King's men are not half a mile behind, and there are nigh three score of them, while half of mine are wounded or sick."
Sigurd stepped out and gripped his hand. "No time for talking, then! Take your sister and the sick or wounded men out to my ships, and let all your fighting men join mine. Take charge of him, Astrid, and use the boats quickly."
The boy called up his men, dividing them as Sigurd had ordered, and joining the Norsemen with twenty Saxons.
"We will give Ethelred's men a sharp
