With Mordo on his shoulder, Polaris stepped onto the deck and through the door, followed by Rombar. Oleric closed the double doors of the craft, and Urk, who was skilled about the engines, at once got her under way. Submerged and showing no light, they crept cautiously down the canal toward the sea. * * * * * In the cabin of the marizel were Everson and Wright--though Polaris had to look twice and then again to recognize the geologist. Zenas wore the mean black of a servant in the king's kitchens. His white hair had been bobbed and his beard shaved from him. But his little black eyes were as bright and restless as ever, and his voice was hearty as he wrung the hand of Polaris and said: "Lordy, son, but it's good to see you." Everson, who had discarded the dirty garments of a delver in the earth for the full golden armor of a Maeronican captain, caught Polaris's hand as Zenas relinquished it. "Our work has begun," he said, "and begun well. I shall distrust this man no more." He pointed to Oleric. "He has kept his promise in blood. He released me to-night, and he killed a man to do it." As they neared the harbor, Oleric explained that they would be forced to leave the marizel in the canal and cross the open court of the harbor to the wharves. "Else we must undergo inspection by the guards at the mouth of the canal," he said. "There is a gate there, and no marizel may pass without inspection. My lucky star it was that made Bel-Ar name me captain of the port in Atlo's stead. But even I could not pass you through the guards. Their eyes are keen, and one of us at least is a marked man in Adlaz." He glanced at Polaris. "There be too many of them to slay," he added. "I would have fitted you out with a suit of mail, brother; but there is none in Maeronica of a size to cover those shoulders of yours--unless it be that of Bel-Ar, which I could not well borrow." "When we leave this craft, what then, Oleric?" Polaris asked. "I have another waiting at the end of the southern quay," replied Oleric. "Urk knows the harbor as he knows the palm of his hand. Once through the outer channel, then down the coast to Ruthar." They left the marizel moored in the canal and went up through a passage in the rock to where a door led into the great arched tunnel above, where Chedar's Flight ended at the harbor of Adlaz town. Now there was only the crossing of the wharf and all would be well. But hark! As Oleric laid his hand on the door of the passage, came the thunder of hoofs through the tunnel, and a steel rider on a white horse flashed past and clattered across the court to the warehouses. He rode furiously, and as he neared the quays he cried out. Oleric tore the door open. "Our work behind there is overtaking us!" he cried. "We must run for it!"
