"Till the sun grows cold,
And the stars are old,
And the leaves of the Judgment Book unfold!"

Softly he sang, as though he had forgotten that she was there. Softly, but with a resonant, vibrating quality that made the words alive and quivering with meaning.

Helen May caught her breath. How did he know she was thinking that song? How did he chance to take it up just at the point where her memory had carried it? Had he read her mind? She stared at him, her lips parted; wondering, a little awed, but listening and thrilling to the human sweetness of his tones. And when he had sung the last yearning note of primitive desire, Starr turned his head and looked into her eyes.

Helen May felt as though he had taken her in his arms and kissed her lingeringly. Yet he had not moved except to turn his face toward her. She could not look away, could not even try to pull her eyes from his. It was as though she yielded. She felt suffocated, though her breath came quickly, a little unevenly.

Starr looked away, across the desert where the moon lighted it whitely. It was as though he had released her. She felt flustered, disconcerted. She could not understand herself or him, or the primary forces that had moved them both. And why had he sung that Bedouin Love Song just as she was thinking it as something that explained him and identified him? It was mysterious as the desert itself lying there so quiet under the moon. It was weird as the cry of the coyote. It was uncanny as spirit rappings. But she could not feel any resentment; only a thrill that was part pleasure and part pain. She wondered if he had felt the same; if he knew. But she could not bring herself to face even the thought of asking him. It was like the night silence around them: speech would dwarf and cheapen and distort.

Rabbit lifted his head again, perking his ears forward toward a new sound that had nothing weird or mysterious about it; a sound that was essentially earthly, material, modern, the distant purr of a high-powered automobile on the trail away to their right. Starr turned his face that way, listening as the horse listened. It seemed to Helen May as though he had become again earthy and material and modern, with the desert love song but the fading memory of a dream. He listened, and she received the impression that something more than idle curiosity held him intent upon the sound.

The purring persisted, lessened, grew louder again. Starr still looked that way, listening intently. The machine swept nearer, so that the clear night air carried the sounds distinctly to where they stood. Starr even caught the humming of the rear gears and knew that only now and then does a machine have that peculiar, droning hum; Starr studied it, tried to impress the sound upon his memory.

The trail looped around the head of a sandy draw and wound over the crest of a low ridge before it straightened out for a three-mile level run in the direction of San Bonito, miles away. In walking, Starr had cut straight across that gully and the loop, so that they had crossed the trail twice in their journey thus far, and were still within half a mile of the head of the loop. They should have been able to see the lights, or at least the reflection of them on the ridge when they came to the draw. But there was no bright path on sky or earth.

They heard the car ease down the hill, heard the grind of the gears as the driver shifted to the intermediate for the climb that came after. They heard the chug of the engine taking the steep grade. Then they should have caught the white glare of the headlights as the car topped the ridge. Starr knew that nothing obstructed the view, that in daylight they could have seen the yellow-brown ribbon of trail where it curved over the ridge. The machine was coming directly toward them for a short distance, but there was no light whatever. Starr knew then that whoever they were, they were running without lights.

"Well, I guess we'd better be ambling along," he said casually, when the automobile had purred its way beyond hearing. "It's three or four miles yet, and you're tired."
