The Pict had run his canoe in close to the shore, and staring up into the bushes, called out something. His answer came in the twang of the bow-string, the streaking flight of the arrow that sank to the feathers in his broad breast. With a choking gasp he slumped sidewise and rolled into the shallow water. In an instant Conan was down the bank and wading into the water to grasp the drifting canoe. Balthus stumbled after him and somewhat dazedly crawled into the canoe. Conan scrambled in, seized the paddle and sent the craft shooting toward the eastern shore. Balthus noted with envious admiration the play of the great muscles beneath the sun-burnt skin. The Cimmerian seemed an iron man, who never knew fatigue.

"What did you say to the Pict?" asked Balthus.

"Told him to pull into shore; said there was a white forest runner on the bank who was trying to get a shot at him."

"That doesn't seem fair," Balthus objected. "He thought a friend was speaking to him. You mimicked a Pict perfectly — "

"We needed his boat," grunted Conan, not pausing in his exertions. "Only way to lure him to the bank. Which is worse — to betray a Pict who'd enjoy skinning us both alive, or betray the men across the river whose lives depend on our getting over?"

Balthus mulled over this delicate ethical question for a moment, then shrugged his shoulders and asked: "How far are we from the fort?"

Conan pointed to a creek which flowed into Black River from the east, a few hundred yards below them.

"That's South Creek; it's ten miles from its mouth to the fort. It's the southern boundary of Conajohara. Marshes miles wide south of it. No danger of a raid from across them. Nine miles above the fort North Creek forms the other boundary. Marshes beyond that, too. That's why an attack must come from the west, across Black River. Conajohara's just like a spear, with a point nineteen miles wide, thrust into the Pictish wilderness."

"Why don't we keep to the canoe and make the trip by water?"

"Because, considering the current we've got to brace, and the bends in the river, we can go faster afoot. Besides, remember Gwawela is south of the fort; if the Picts are crossing the river we'd run right into them."

Dusk was gathering as they stepped upon the eastern bank. Without pause Conan pushed on northward, at a pace that made Balthus' sturdy legs ache.

"Valannus wanted a fort built at the mouths of North and South Creeks," grunted the Cimmerian. "Then the river could be patrolled constantly. But the Government wouldn't do it.

"Soft-bellied fools sitting on velvet cushions with naked girls offering them iced wine on their knees. — I know the breed. They can't see any farther than their palace wall. Diplomacy — hell! They'd fight Picts with theories of territorial expansion. Valannus and men like him have to obey the orders of a set of damned fools. They'll never grab any more Pictish land, any more than they'll ever rebuild Venarium. The time may come when they'll see the barbarians swarming over the walls of the eastern cities!"

A week before, Balthus would have laughed at any such preposterous suggestion. Now he made no reply. He had seen the unconquerable ferocity of the men who dwelt beyond the frontiers.

He shivered, casting glances at the sullen river, just visible through the bushes, at the arches of the trees which crowded close to its banks. He kept remembering that the Picts might have crossed the river and be lying in ambush between them and the fort. It was fast growing dark.

A slight sound ahead of them jumped his heart into his throat, and Conan's sword gleamed in the air. He lowered it when a dog, a great, gaunt, scarred beast, slunk out of the bushes and stood staring at them.

"That dog belonged to a settler who tried to build his cabin on the bank of the river a few miles south of the fort," gruntcd Conan. "The Picts slipped over and killed him, of course, and burned his cabin. We found him dead among the embers, and the dog lying senseless among three Picts he'd killed. He was almost cut to pieces. We took him to the fort and dressed his wounds, but after he recovered he took to the woods and turned wild. — What now, Slasher, are you hunting the men who killed your master?"

The massive head swung from side to side and the eyes glowed greenly. He did not growl or bark. Silently as a phantom he slid in behind them.

"Let him come," muttered Conan. "He can smell the devils before we can see them."

Balthus smiled and laid his hand caressingly on the dog's head. The lips involuntarily writhed back to display the gleaming fangs; then the great beast bent his head sheepishly, and his tall moved with jerky uncertainty, as if the owner had almost forgotten the emotions of friendliness. Balthus mentally compared the great gaunt hard body with the fat sleek hounds tumbling vociferously over one another in his father's kennel yard. He sighed. The frontier was no less hard for beasts than for men. This dog had almost forgotten the meaning of kindness and friendliness.

Slasher glided ahead, and Conan let him take the lead. The last tinge of dusk faded into stark darkness. The miles fell away under their steady feet. Slasher seemed voiceless. Suddenly he halted, tense, ears lifted. An instant later the men heard it — a demoniac yelling up the river ahead of them, faint as a whisper.

Conan swore like a madman.

"They've attacked the fort! We're too late! Come on!"

He increased his pace, trusting to the dog to smell out ambushes ahead. In a flood of tense excitement Balthus forgot his hunger and weariness. The yells grew louder as they advanced, and above the devilish screaming they could hear the deep shouts of the soldiers. Just as Balthus began to fear they would run into the savages who seemed to be howling just ahead of them, Conan swung away from the river in a wide semicircle that carried them to a low rise from which they could look over the forest. They saw the fort, lighted with torches thrust over the parapets on long poles. These cast a flickering, uncertain light over the clearing, and in that light they saw throngs of naked, painted figures along the fringe of the clearing. The river swarmed with canoes. The Picts had the fort completely surrounded.

An incessant hail of arrows rained against the stockade from the woods and the river. The deep twanging of the bowstrings rose above the howling. Yelling like wolves, several hundred naked warriors with axes in their hands ran from under the trees and raced toward the eastern gate. They were within a hundred and fifty yards of their objective when a withering blast of arrows from the wall littered the ground with corpses and sent the survivors fleeing back to the trees. The men in the canoes rushed their boats toward the river-wall, and were met by another shower of clothyard shafts and a volley from the small ballistae mounted on towers on that side of the stockade. Stones and logs whirled through the air and splintered and sank half a dozen canoes, killing their occupants, and the other boats drew back out of range. A deep roar of triumph rose from the walls of the fort, answered by bestial howling from all quarters.

"Shall we try to break through?" asked Balthus, trembling with eagerness.

Conan shook his head. He stood with his arms folded, his head slightly bent, a somber and brooding figure.

"The fort's doomed. The Picts are blood-mad, and won't stop until they're all killed. And there are too many of them for the men in the fort to kill. We couldn't break through, and if we did, we could do nothing but die with Valannus."

"There's nothing we can do but save our own hides, then?"
