Here Carthoris found considerable difficulty in subduing the second thoat, and as Kar Komak had never before ridden one of the beasts, it seemed a most hopeless job; but at last the bowman managed to scramble to the sleek back, and again the two beasts fled softly down the moss-grown avenues toward the open sea-bottom beyond the city. All that night and the following day and the second night they rode toward the north-east. No indication of pursuit developed, and at dawn of the second day Carthoris saw in the distance the waving ribbon of great trees that marked one of the long Barsoomian water-ways. Immediately they abandoned their thoats and approached the cultivated district on foot. Carthoris also discarded the metal from his harness, or such of it as might serve to identify him as a Heliumite, or of royal blood, for he did not know to what nation belonged this waterway, and upon Mars it is always well to assume every man and nation your enemy until you have learned the contrary. It was mid-forenoon when the two at last entered one of the roads that cut through the cultivated districts at regular intervals, joining the arid wastes on either side with the great, white, central highway that follows through the centre from end to end of the far-reaching, threadlike farm lands. The high wall surrounding the fields served as a protection against surprise by raiding green hordes, as well as keeping the savage banths and other carnivora from the domestic animals and the human beings upon the farms. Carthoris stopped before the first gate he came to, pounding for admission. The young man who answered his summons greeted the two hospitably, though he looked with considerable wonder upon the white skin and auburn hair of the bowman. After he had listened for a moment to a partial narration of their escape from the Torquasians, he invited them within, took them to his house and bade the servants there prepare food for them. As they waited in the low-ceiled, pleasant living room of the farmhouse until the meal should be ready, Carthoris drew his host into conversation that he might learn his nationality, and thus the nation under whose dominion lay the waterway where circumstance had placed him. “I am Hal Vas,” said the young man, “son of Vas Kor, of Dusar, a noble in the retinue of Astok, Prince of Dusar. At present I am Dwar of the Road for this district.” Carthoris was very glad that he had not disclosed his identity, for though he had no idea of anything that had transpired since he had left Helium, or that Astok was at the bottom of all his misfortunes, he well knew that the Dusarian had no love for him, and that he could hope for no assistance within the dominions of Dusar. “And who are you?” asked Hal Vas. “By your appearance I take you for a fighting man, but I see no insignia upon your harness. Can it be that you are a panthan?”
