He went back to his comrade, who slept soundly beside the horses, also extended and breathing deeply. It was nearly morning when he woke Adan, so little aptitude had his brain for sleep. But when Adan sat up he fell asleep almost immediately, and when he awoke the sun was high. XXII Roldan raised himself on his elbow and looked about him. Adan was some quarter of a mile away, approaching him, leading the mustangs. Cleaving the horizon on four sides was a vast plain. On it was not a tree, nor even a hut. Here and there were clumps of palms and cacti, as stark as if cut from pale green stone. At vast intervals were short, isolated mountains, known in the vernacular as "buttes." On the ground was not the withered remnant of a blade of grass; but there were many fissures, and some of them were deep and wide. Of the things that crawl and scamper and fly there was no sign, not even a hole in the ground; for even reptiles must have food to eat, and there was nothing here to sustain man nor beast. The fleckless sky was a deep, hot blue; a blood-red sun toiled heavily toward the zenith. "Adan!" shouted Roldan; he was suddenly mad for sound of any sort. A discouraged "Halloa!" came promptly back. Roldan dressed himself rapidly. His clothes were quite dry; indeed the very atmosphere of this strange beautiful place was so dry that it seemed to crumble in the nostrils. As he finished dressing Adan reached him. The horses' heads were hanging listlessly. Adan's face had lost its ruddy colour. "Roldan," he said, "where are we?" "I know not," said Roldan, setting his lips. "I left you to look for water, and there are not even tarantulas in this accursed place. There is no water, not a drop. Nor a handful of stubble for the horses." "We must go back the way we came, and start once more from the foot of the mountain." "Can you remember from which point we entered this place? This soil might be rock; there is not a hoof-print anywhere." "We should have gone south and we came east. On the northwestern horizon is something which looks like mountains--a long range--almost buried in mist. There is no sign of a range anywhere else; so the only thing to do is to go back to them; they are our mountains; I feel sure of that." "If the horses do not give out. They are empty and choking, poor things. Well, there is no reason we should not eat, and, thanks be to that good mayor domo, we still have a bottle of wine. But I would give something for a gourd of water. However, we have not been girls yet, and we will not begin now, my friend."
