He sat up and rolled a cigarette; he sat still while he smoked it. Here was plainly a time for cool thinking; he would take all of the time that he needed to be sure that he had decided correctly. For later there might be no minute to squander. At present he had both food and water. At present he could go on or turn back. There was water where he had left his saddle; he could count on that positively and could get to it before he had emptied his canteen. But, if instead he went forward, there could be no turning back. He studied his map again. So far as he could make out from it, it was as well to go on as to retreat. So, putting his paper into his pocket he took up his food and water, made certain of his bearings and went on. It was a gamble, but a gamble his life had always been, and a fair gamble, an even break, is all that men like Alan Howard ask. He realized with a full measure of grimness that never until now had he placed a wager like this one; he was betting heavily and he knew not against what odds that at the end of twenty miles he would find water. Hour after hour he trudged on. His feet burned; they ached; his boots made blisters and the blisters broke. Always he was thirsty with a thirst which his whole supply of water could not have slacked and which grew steadily more acute. Now and then he paused briefly and drank sparingly. His bundle of food, small as it was, grew heavy; his feet were heavy; only his canteen seemed to him lighter and lighter. A hot wind rose, blowing direct into his face, flinging at him fine particles of burning sand that sifted through his clothing and got into his boots, torturing further his tortured feet; the wind seared his eyeballs and threatened to blind him. He lifted his head, selected a distant landmark, sought to shelter his eyes with the broad brim of his hat and went on. Noon found him plunging down the steep bank of a dry gulch, a hideous gash in the breast of the hideous land. He found a spot where there was a little shade under a clump of bushes growing upon the bank's edge. He ate a little of his dried beef; he treated himself to half a dozen big, slow swallows of water; then he lay and rested for half an hour. Again he rose; he moistened his mouth and lips, shut his teeth hard together as he took the first step upon swollen feet; again he wandered monotonously through a monotonous land. There was no wind now save, infrequently, frolicsome little whirlwinds which danced about him and were gone. When he found that their play angered him, that they seemed to mock at his weariness and dying energies, he frowned. This was no time and here was no place for nerves.
