There was no hesitation. Like a panther Lajo swung upon his adversary, striking up the other's knife-hand with his left forearm and at the same time plunging his villainous looking blade to the hilt in the other's breast. Voicing a single blood-curdling scream the man sank lifeless to the bottom of the boat. Lajo wrenched his knife from the corpse, wiped it upon his adversary's shirt and quietly cut the bonds that confined the wrists of Thoar and Jason. The other Korsars looked on, apparently unmoved by the killing of their fellow, except for a coarse joke or two at the expense of the dead man and a grunt of approbation for Lajo's act.
The killer removed the weapons from the body of the dead man and cast them aft out of reach of the prisoners, then he motioned to the corpse. "Throw it overboard," he commanded, addressing Jason and Thoar.
"Wait," cried another member of the crew. "I want his boots."
"His sash is mine," cried another, and presently half a dozen of them were quarreling over the belongings of the corpse like a pack of dogs over a bone. Lajo took no part in this altercation and presently the few wretched belongings that had served to cover the nakedness of the dead man were torn from his corpse and divided among them by the simple expedient of permitting the stronger to take what they could; then Jason and Thoar eased the naked body over the side, where it was immediately seized upon by voracious denizens of the river.
Interminable, to an unknown destination, seemed the journey to Jason. They ate and slept many times and still the river wound through the endless swamp. The luxuriant vegetation and flowering blooms which lined the banks long since had ceased to interest, their persistent monotony making them almost hateful to the eyes.
Jason could not but wonder at the superhuman efforts that must have been necessary to row this large, heavy boat upstream in the face of all the terrific assaults which must have been launched upon it by the reptilian hordes that contested every mile of the downward journey.
But presently the landscape changed, the river widened and the low swamp gave way to rolling hills. The forests, which still lined the banks, were freer from underbrush, suggesting that they might be the feeding grounds of droves of herbivorous animals, a theory that was soon substantiated by sight of grazing herds, among which Jason recognized red deer, bison, bos and several other species of herbivorous animals. The forest upon the right bank was open and sunny and with its grazing herds presented a cheerful aspect of warmth and life, but the forest upon the left bank was dark and gloomy. The foliage of the trees, which grew to tremendous proportions, was so dense as practically to shut out the sunlight, the space between the boles giving the impression of long, dark aisles, gloomy and forbidding.
There were fewer reptiles in the stream here, but the Korsars appeared unusually nervous and apprehensive of danger after they entered this stretch of the river. Previously they had been drifting with the current, using but a single oar, scull fashion, from the stern to keep the nose of the boat pointed downstream, but now they manned the oars, pressing Jason and Thoar into service to row with the others. Loaded arquebuses lay beside the oarsmen, while in the bow and stern armed men were constantly upon watch. They paid little attention to the right bank of the river, but toward the dark and gloomy left bank they directed their nervous, watchful gaze. Jason wondered what it was that they feared, but he had no opportunity to inquire and there was no respite from the rowing, at least not for him or Thoar, though the Korsars alternated between watching and rowing.
Between oars and current they were making excellent progress, though whether they were close to the end of the danger zone or not, Jason had no means of knowing any more than he could guess the nature of the menace which must certainly threaten them if aught could be judged by the attitude of the Korsars.
The two prisoners were upon the verge of exhaustion when Lajo noticed their condition and relieved them from the oars. How long they had been rowing, Jason could not determine, although he knew that while no one had either eaten or slept, since they had entered this stretch of the river, the time must have been considerable. The distance they had come he estimated roughly at something over a hundred miles, and he and Thoar had been continuously at the oars during the entire period, without food or sleep, but they had barely thrown themselves to the bottom of the boat when a cry, vibrant with excitement, arose from the bow. "There they are!" shouted the man, and instantly all was excitement aboard the boat.
