But Ulf was not by birth a Northman. Yet a rover by nature was he, and chief of all things that he most desired was to explore strange lands, and especially what lay beyond where the sky dipped downward and seemed to meet the sea. Ships came from thence, now and then; ships had gone thence, as he knew, and some had never come back, but perhaps were sailing still from land to land, through the great unknown.
For weeks his ship sailed onward, over a lonely ocean. Now and then the misty fountain sprung upward from the waves where a whale was "blowing," with gulls hovering in the air above his glistening black back. There were more gulls then than now, and more whales also, and often the men would finger their lances wistfully and look with inquiring eyes at their youthful captain. At another time they would not have looked in vain; indeed, in after days Ulf became somewhat famous even among the men of the fjords for the number of whales he brought in. But now his soul was elsewhere. Even the problem of getting back did not trouble him in the least.
Yet it was one thing to start out a-voyaging, sure of bringing up somewhere if you only went far enough. It is quite another thing to be equally sure of finding the way homeward over the trackless sea, without a landmark from horizon to horizon to steer by for weeks and weeks. What seems a sixth sense is given to some of us—the sense of "direction," which the passenger pigeon has and which enables it to fly straight back to its nest, though set free hundreds of miles from home. When of old a young man had that faculty, the chances were that he would become a famous pilot; and sometimes he might be charged with witchcraft as a penalty for knowing too much! Ulf, a son of the trackless Forest, had that sixth sense.
One morning the dawn-light revealed a black spot on the low horizon. A speck that grew larger, with twinkling, fin-like flashes along each side, and in due time it proved to be a galley like their own bearing down straight for them. Nobody stopped to ask any questions. That was not sea-style then. But just as naturally as two men now in a lonely journey would shake hands on meeting, these two captains slipped their arms through their shield-handles, sheered alongside just beyond oar- tip, and exchanged cards in the shape of a couple of whistling javelins.
Up from their benches sprang the rowers. Twang! sung their war-bows the song of the cord, and the air was full of hissing whispers of Death as their shafts hurtled past. Round and round the two galleys circled in a strange dance, each steersman striving to bring his craft bows on, so as to ram and crush the other, while they lurched in the cross-seas, and rolled till they dipped in tons of water over the rail.
Up sprang the stranger on his prow; tall and broad-shouldered was he, with a torrent of ruddy hair floating in the wind. As Ulf turned to give an order to bale out the inrushing water, up rose a brawny arm, and a great spear flashed down from the high bow of the enemy and struck fairly between his shoulders. So sharp was the blow, so sudden, that Ulf pitched forward on one knee for just half a breath. But the spear fell clanging to the deck. The ruddy warrior stood looking at it with eyes of amazement. His own spear, that never before had failed! A flash of light leaped back like a lightning stroke; back to its master whistled the brand, for, ere he rose, Ulf snatched it up and as he rose he hurled it—straight through the unguarded arm of the stranger.
"Hold!"
The shout rang sternly across the water and echoed back and forth from sail to sail. The shouting hushed. Only the creak of the swaying yard, the hoarse swash of the water, the panting of deep breathing broke the silence, then once more from the lofty prow came the commanding voice.
"Who and whence art thou?"
"A son of the Forest am I," answered the other. "Ulf is my name, Ulf the Silent my title, Jarl Sigurd my father by adoption. The sea is my home; from over sea I came, and over sea am I going."
