CHAPTER XXIII

BETWEEN EARTH AND SKY

Before starting on her perilous venture, Grace had directed that the

rope be paid out slowly, so as not to set up so much friction that the

rope would be in danger of burning.

As she went over, Grace took one look below her and closed her eyes,

but after a few moments she summoned her courage, opened her eyes and

looked down. She could see, directly beneath her, the ledge under which

the Cliff Dwellers’ Community House had been constructed. Out in front

of the ledge were the white stone walls and part of the roof of the

ancient structure, which she was on her way to explore.

“Getting down is easy. It is getting back that is going to be the big

problem,” muttered the plucky girl. “It is worth the risk. Think of

it, Grace Harlowe, you possibly will be the first human being to set

foot on that shelf of rock in ten centuries, perhaps ten times ten

centuries.”

Grace wriggled and twisted herself into position for a suitable

landing, and, as it was, she grazed the wall of the cliff dwelling,

slipping down the side of it, kicking out vigorously to keep from

tearing her clothing on the protruding points of stone, until her feet

touched the ground.

“Down! Harlowe luck is with me thus far.” Grace hastily penciled a

note, reading:

“Arrived safely. Send the string back with a small stone to weight it.

Fine view down here. I start exploring. Don’t worry if you don’t hear

from me for an hour or so.”

One tug on the line, and the Overton girl was rewarded by seeing her

message slowly rising at the end of the twine.

Grace thereupon took account of her surroundings. With her glass she

picked up the Lodge, then the tiny dots that she knew were the Overland

Riders’ tents. It was a clear view to the camp, and, as Grace described

it to herself, a good shooting range.

Now began her explorations. There were heaps of rotted stone and

adobe mortar all about, but taking it all in all, the community house

appeared to be in an excellent state of preservation. Grace took

her time, and moved slowly, using extreme caution, not knowing what

emergency she might have to meet at any moment. Over heaps of stone

and rubbish she climbed to such chambers as she could reach. The

ceilings in the Community House were so low that she was obliged to

stoop; window apertures were no more than six inches across and of

equal height, but the light shed by these was sufficient to enable her

to pick her way about.

The mustiness of centuries hung heavy on the air despite the

ventilation, and birds, disturbed by her entrance, gave Grace a start

as they winged their way toward the light. Not a relic, however, did

the Overton girl find in her search of the chambers.

On coming out of the cliff dwelling, Grace suddenly halted and sniffed

the air.

“That smells like a dead fire,” she muttered. “Perhaps I have company

here.” Picking her way cautiously in under the ledge that formed a

partial roof for the ancient Community House, Grace found herself in

a vast, tunnel-like opening. Black darkness lay ahead of her, but the

odor of a dead fire grew stronger in her nostrils as she proceeded.

Grace now brought her flash lamp from her pocket, passing it to her

left hand, and, holding the automatic in a firm grip in her right, she

advanced, prepared for emergencies.

She examined the walls briefly. From their smoothness, it occurred

to Grace that water had once flowed through the tunnel. How far back

the tunnel led into the mountain she could not even guess, but it

was reasonable to suppose that it was not a waterway when the Cliff

Dwellers lived there.

“I am getting near it! The dead fire odor is growing stronger!” Grace

told herself in a whisper. “I believe my surmises are correct. How

I wish one of the men were with me. However, I’m in it and must go

through with it,” she muttered.

Using her flash lamp to guard against stepping into a pitfall, the

Overton girl picked her way cautiously along. Here and there were huge

crevices in the wall of the tunnel, which, as Grace described it to

herself, was in reality “the rear yard of the ancient Cliff Dwellers.”

The crevices, as she shot rays of light into them, were dark and

forbidding, but, looking back, the white towers of the Community House

stood out reassuringly.

“Ah!”

Grace had stepped into a heap of ashes and they felt warm under her

feet. Stooping over and running her hand into the mass she found that

the ashes, at the bottom, really were warm.

“There has been a recent fire here, but the ashes are several hours

old. I wish Tom were here. He could tell me, within half an hour, just

how long ago this heap was a blazing fire. Let me reason this out.”

Grace leaned against the wall and reflected.

“Some one has been in this place within a dozen hours or so. It is

reasonable to assume, too, that they did not come over the precipice;

hence there must be some other entrance, some other way, and perhaps an

easier one. I am going on.”

Grace started ahead resolutely, now and then flashing a ribbon of light

to the floor directly ahead of her. Her keenness was rewarded a few

moments later, and the Overton girl, dropping to her knees, examined

the rocky floor with great care.

What Grace had discovered was the imprint of a heavy-soled boot, faint

but clearly defined. Her next discovery was a frying pan, some tin

plates and a heap of bones that looked as if they might be beef bones.

“They surely live well up here. I--”

Grace jumped. That is, her nerves did; her body did not move at all,

but she heard her heart beat, and it was pounding fast and hard. What

had disturbed and startled her was a groan, a distinctly human groan,

and then deep silence settled over the tunnel, broken only by the

faint, repressed breathing of Grace herself.

The natural impulse was to turn on her light, but Grace Harlowe was too

prudent to do that just yet. She preferred to wait and listen. This

policy produced results. A second groan, more prolonged than before,

followed.

It was a human groan of distress that she had heard, though whether

real or feigned the girl was unable to decide in her own mind, but she

now realized that she must make the advance herself. Arriving at this

decision, Grace turned on her light, and, with the automatic revolver

thrust ahead of her, ready for instant use, she began a cautious

search for the source of the voice.

“Groan again, so I may know where you are,” she called softly. “If you

are hoping to play a trick on me I shall shoot on sight!”

The response came back almost at once, the voice sounding ahead of her

and to the right side of the tunnel. She moved forward with renewed

caution, and, a few steps further on, as she flashed her ribbon of

light into a niche in the wall of the tunnel, she saw him.

Grace approached cautiously, still holding her weapon at ready, for,

though she was looking down on a man, apparently hound and gagged, she

proposed to take no more than the absolutely necessary chances.

Leaning over, with the revolver pointed down at him, Grace turned the

light of her lamp into the face of the owner of the voice. As she did

so she uttered an exclamation of amazement.
