With a sudden sharpening of her senses, Harry peered into the dusk. Perhaps some one who could help her was passing near by. She listened intently, with every nerve alert.
Suddenly she stood up in the wagon and screamed:
"Help! Help! Help!"
A clamor of echoes answered her ringing cries, and 'Thello challenged them furiously. The girl stood silent. As her voice struck back mockingly at her from barren butte and rock, she realized that she was helpless, and lonely, and afraid. Drawing a deep breath, she shut her hands tight. She would not give up to fear! Steadying her voice, she put all her strength into one more call:
"Help!"
"Coming!" A man's voice answered her.
The shout echoed her cry, a rattle of hoofs swept suddenly near, and Harry saw a horseman appear over the ridge. His figure rose and fell in silhouette as he galloped toward her. "It's Garnett!" Harry thought joyfully.
"Hello, what's doing?" he asked, as he pulled up. "Any one hurt? Who is it?"
"It's Harriet Holliday. I'm lost. I got over into those queer rocks and couldn't get out."
Garnett caught the quaver in her laugh. "Lucky I was riding through this way," he said. "That was the city of rocks you were in. How did you get out? Even fellows that know the country have got balled up in there and come pretty near cashing in before they struck the trail again."
