John rose stiffly.

"Do you feel equal to climbing this trail with me, to find where we are, or had you rather stay here?"

"I don't want to stay here alone," answered Rhoda.

Very slowly and weakly they started up the trail. The spring was on a broad stone terrace. Above it rose another terrace weathered and disrupted until in the moonlight it looked like an impregnable castle wall, embattled and emb.u.t.tressed. But clinging to the seemingly invulnerable fortress was the trail, a snake-like shadow in the moonlight.

"Perhaps we had better stay at the spring until morning," suggested Rhoda, her weak legs flagging.

"Not with the hope of shelter a hundred feet above us," answered John firmly. "This trail is worn six inches into the solid rock. My guess is that there are some inhabitants here. It's queer that they haven't discovered us."

Slowly and without further protest, Rhoda followed DeWitt up the trail.

Deep-worn and smooth though it was, they accomplished their task with infinite difficulty. Rhoda, stumbling like a sleep-sodden child, wondered if ever again she was to accomplish physical feats with the magical ease with which Kut-le had endowed her.

"If he were here, I'd know I was to tumble into a comfortable camp,"

she thought. Then with a remorseful glance at DeWitt's patient back, "What a selfish beast you are, Rhoda Tuttle!"

She reached John's side and together they paused at the top of the trail. Black against the sky, the moon crowning its top with a frost-like radiance, was a huge flat-topped building. Night birds circled about it. From black openings in its front owls hooted. But otherwise there was neither sight nor sound of living thing. The desert far below and beyond lay like a sea of death. Rhoda unconsciously drew nearer to DeWitt.

"Where are the dogs? At Chira the dogs barked all night. Indians always have dogs!"

"It must be very late," whispered DeWitt. "Even the dogs are asleep!"

"And at Chira," went on Rhoda, whispering as did DeWitt, "owls didn't hoot from the windows."

"Let's go closer," suggested John.

Rhoda thrust cold little fingers into his hand.

The doors were empty and forlorn. The terraced walls, built with the patient labor of the long ago, were sagged and decayed. Riot of greasewood crowned great heaps of debris. A loneliness as of the end of the world came upon the two wanderers. Sick and dismayed, they stood in awe before this relic of the past.

"_Whoo_! _Whoo_!" an owl's cry sounded from the black window openings.

DeWitt spoke softly.

"Rhoda, it's one of the forgotten cities!"

"Let's go back! Let's go back to the spring!" pleaded Rhoda. "It is so uncanny in the dark!"

"No!" DeWitt rubbed his aching head wearily. "I must contrive some sort of shelter for you. Almost anything is better than another night in the open desert. Come on! We will explore a little."

"Let's wait till morning," begged Rhoda. "I'm so cold and shivery."

"Dear sweetheart, that's just the point. You will be sick if you don't have some sort of shelter. You have suffered enough. Will you sit here and let me look about?"

"No! No! I don't want to be left alone."

Rhoda followed John closely up into the ma.s.s of fallen rock.

DeWitt smiled. It appealed to the tenderest part of his nature that the girl who had led him through the terrible experiences of the desert should show fear now that a haven was reached.

"Come on, little girl," he said.

Painfully, for they both were weak and dizzy, they clambered to a gaunt opening in the gray wall. Rhoda clutched John's arm with a little scream as a bat whirred close by them. Within the opening DeWitt scratched one of his carefully h.o.a.rded matches. The tiny flare revealed a small adobe-walled room, quite bare save for broken bits of pottery on the floor. John lighted a handful of greasewood and by its brilliant light they examined the floor and walls.

"What a clean, dry little room!" exclaimed Rhoda. "Oh, I am so tired and sleepy!"

"Let's look a little farther before we stop. What's on the other side of this broken wall?"

They picked their way across the litter of pottery and peered into another room, the duplicate of the first.

"How will these do for our respective sleeping-rooms?" asked DeWitt.

Rhoda stared at John with horror in her eyes.

"I'd as soon sleep in a tomb! Let's make a fire outside and sleep under the stars. I'd rather have sleep than food just now."

"It will have to be just a tiny smudge, up behind this debris, where Kut-le can't spot it," answered DeWitt. "I won't mind having a red eye of fire for company. It will help to keep me awake."

"But you must sleep," protested Rhoda.

"But I mustn't," answered John grimly. "I've played the baby act on this picnic as much as I propose to. It is my trick at the wheel."

Too weary to protest further, Rhoda threw herself down with her feet toward the fire and pillowed her head on her arm. DeWitt filled his pipe and sat puffing it, with his arms folded across his knees. Rhoda watched him for a moment or two. She found herself admiring the full forehead, the lines of refinement about the lips that the beard could not fully conceal.

"He's not as handsome as Kut-le," she thought wearily, "but he's--he's--" but before her thought was completed she was asleep.

Rhoda woke at dawn and lay waiting for the stir of the squaws about the morning meal. Then with a start she rose and looked soberly about her.

Suddenly she smiled.

"Tenderfoot!" she murmured.

DeWitt lay fast asleep by the ashes of the fire.

"If Kut-le," she thought. Then she stopped abruptly and stamped her foot. "You are not even to think of Kut-le any more!" And with her cleft chin very firm she descended the trail to the spring. When she returned, DeWitt was rising stiffly to his feet.

"h.e.l.lo!" he cried. "I was good this time. I never closed my eyes till dawn. I'm so hungry I could eat greasewood. How do you feel?"

"Weak with hunger but otherwise very well. Go wash your face, Johnny."

DeWitt grinned and started down the trail obediently. But Rhoda laid a detaining hand on his arm. The sun was but a moment high. All the mesa front lay in purple shadows, though farther out the desert glowed with the yellow light of a new day.

"I think animals come to the spring to drink," said Rhoda. "There were tiny wet footmarks there when I went down to wash my face."

"Bully!" exclaimed John. "Wait now, let's watch."

The two dropped to the ground and peered over the edge of the upper terrace. The spring bubbled forth serenely, followed its shallow trough a short distance, then disappeared into the insatiable floor of the desert. For several moments the two lay watching until at last Rhoda grew restless. DeWitt laid a detaining hand on her arm.

"Hush!" he whispered.
