The heat grew steadily fiercer; all distant objects were visibly shimmering and palpitating under it. At noon a mirage appeared on the hills to the northwest. McTeague halted the mule, and drank from the tepid water in the canteen, dampening the sack around the canary's cage. As soon as he ceased his tramp and the noise of his crunching, grinding footsteps died away, the silence, vast, illimitable, enfolded him like an immeasurable tide. From all that gigantic landscape, that colossal reach of baking sand, there arose not a single sound. Not a twig rattled, not an insect hummed, not a bird or beast invaded that huge solitude with call or cry. Everything as far as the eye could reach, to north, to south, to east, and west, lay inert, absolutely quiet and moveless under the remorseless scourge of the noon sun. The very shadows shrank away, hiding under sage-bushes, retreating to the farthest nooks and crevices in the canyons of the hills. All the world was one gigantic blinding glare, silent, motionless. "If it gets much hotter," murmured the dentist again, moving his head from side to side, "if it gets much hotter, I don' know what I'll do."
Steadily the heat increased. At three o'clock it was even more terrible than it had been at noon.
"Ain't it EVER going to let up?" groaned the dentist, rolling his eyes at the sky of hot blue brass. Then, as he spoke, the stillness was abruptly stabbed through and through by a shrill sound that seemed to come from all sides at once. It ceased; then, as McTeague took another forward step, began again with the suddenness of a blow, shriller, nearer at hand, a hideous, prolonged note that brought both man and mule to an instant halt.
"I know what THAT is," exclaimed the dentist. His eyes searched the ground swiftly until he saw what he expected he should see--the round thick coil, the slowly waving clover- shaped head and erect whirring tail with its vibrant rattles.
For fully thirty seconds the man and snake remained looking into each other's eyes. Then the snake uncoiled and swiftly wound from sight amidst the sagebrush. McTeague drew breath again, and his eyes once more beheld the illimitable leagues of quivering sand and alkali.
"Good Lord! What a country!" he exclaimed. But his voice was trembling as he urged forward the mule once more.
Fiercer and fiercer grew the heat as the afternoon advanced.
At four McTeague stopped again. He was dripping at every pore, but there was no relief in perspiration. The very touch of his clothes upon his body was unendurable. The mule's ears were drooping and his tongue lolled from his mouth. The cattle trails seemed to be drawing together toward a common point; perhaps a water hole was near by.
"I'll have to lay up, sure," muttered the dentist. "I ain't made to travel in such heat as this."
He drove the mule up into one of the larger canyons and halted in the shadow of a pile of red rock. After a long search he found water, a few quarts, warm and brackish, at the bottom of a hollow of sunwracked mud; it was little more than enough to water the mule and refill his canteen. Here he camped, easing the mule of the saddle, and turning him loose to find what nourishment he might. A few hours later the sun set in a cloudless glory of red and gold, and the heat became by degrees less intolerable. McTeague cooked his supper, chiefly coffee and bacon, and watched the twilight come on, revelling in the delicious coolness of the evening. As he spread his blankets on the ground he resolved that hereafter he would travel only at night, laying up in the daytime in the shade of the canyons. He was exhausted with his terrible day's march. Never in his life had sleep seemed so sweet to him.
But suddenly he was broad awake, his jaded senses all alert.
"What was that?" he muttered. "I thought I heard something --saw something."
He rose to his feet, reaching for the Winchester. Desolation lay still around him. There was not a sound but his own breathing; on the face of the desert not a grain of sand was in motion. McTeague looked furtively and quickly from side to side, his teeth set, his eyes rolling. Once more the rowel was in his flanks, once more an unseen hand reined him toward the east. After all the miles of that dreadful day's flight he was no better off than when he started. If anything, he was worse, for never had that mysterious instinct in him been more insistent than now; never had the impulse toward precipitate flight been stronger; never had the spur bit deeper. Every nerve of his body cried aloud for rest; yet every instinct seemed aroused and alive, goading him to hurry on, to hurry on.
"What IS it, then? What is it?" he cried, between his teeth. "Can't I ever get rid of you? Ain't I EVER going to shake you off? Don' keep it up this way. Show yourselves. Let's have it out right away. Come on. I ain't afraid if you'll only come on; but don't skulk this way." Suddenly he cried aloud in a frenzy of exasperation, "Damn you, come on, will you? Come on and have it out."
His rifle was at his shoulder, he was covering bush after bush, rock after rock, aiming at every denser shadow. All at once, and quite involuntarily, his forefinger crooked, and the rifle spoke and flamed. The canyons roared back the echo, tossing it out far over the desert in a rippling, widening wave of sound.
McTeague lowered the rifle hastily, with an exclamation of dismay.
"You fool," he said to himself, "you fool. You've done it now. They could hear that miles away. You've done it now."
He stood listening intently, the rifle smoking in his hands.
The last echo died away. The smoke vanished, the vast silence closed upon the passing echoes of the rifle as the ocean closes upon a ship's wake. Nothing moved; yet McTeague bestirred himself sharply, rolling up his blankets, resaddling the mule, getting his outfit together again.
From time to time he muttered:
"Hurry now; hurry on. You fool, you've done it now. They could hear that miles away. Hurry now. They ain't far off now."
