"Allen," she said, as he stopped for an instant to rest, "come here and sit down beside me."
He had never hesitated before at accepting that coveted invitation, but just now he wondered whether he ought to stop even for an instant. His herculean efforts had brought him to the very edge of collapse, but he was feverishly eager to keep on.
"Ought I, Ruth?" he questioned. "Every minute now is precious, you know."
"I know it," she admitted, "but you'll drop dead from exhaustion if you don't stop and rest. You must rest."
The gentle tyrant had her way and Drew yielded. He sat down beside her, his chest contracting and expanding under the stress of his labored breathing.
"Poor boy!" she said softly, and Drew thrilled at the sympathy in her tone.
"I've been thinking, Allen, that perhaps we had better not rely entirely on your digging for getting out of here," she continued. "It's all a guess as to how thick that wall of earth and rock is, and we may be using on it the strength that we need for other things. If you had an implement of some kind it would be different. But with your bare hands together with what little help I can give you it may be impossible."
"Yes," he was forced to concede, "I can't go on forever. Sooner or later my strength will give out. But what can we do but keep on trying? I'd go raving mad if I didn't keep on taking the one little chance we have."
"But is it the only chance we have?" she argued. "Did you bring your revolver with you?"
For answer he took it out of his belt and put it in her hand.
