"Is he in—danger, Danny?"

"Yes—no! Mellen says it's all right, so it must be, but—that dam—"

At that moment Natalie began to sob hysterically, and Dan turned his attention to her.

But his sister was not of the hysterical kind. Seizing Tom Slater by the arm, she tried to shake him, demanding fiercely:

"Suppose the jam doesn't give way! What will happen?" "Happy Tom" stared at her uncomprehendingly. Her voice was shrill and insistent. "Suppose the water rises higher. Won't the ice sweep down on the bridge itself? Won't it wreck everything if it goes out suddenly? Tell me—"

"It can't hold. Mellen says so." Slater, like the others, found it impossible to keep his eyes from the river where those immeasurable forces were at play; then in his peculiar irascible manner he complained: "I told 'em we was crazy to try this. It ain't a white man's country; it ain't a safe place for a bridge. There's just one God-awful thing after another—" He broke into a shout, for Eliza had slipped past him and was speeding like a shadow out across the irregularly spaced ties upon which the bridge track was laid.

Mellen whirled at the cry and made after her, but he might as well have tried to catch the wind. As she ran she heard her brother shout in sudden alarm and Natalie's voice raised in entreaty, but she sped on under an impulse as irresistible as panic fear. Down through the openings beneath her feet she saw, as in a nightmare, the sweeping flood, burdened with plunging ice chunks and flecked with foam. She seemed to be suspended above it; yet she was running at reckless speed, dimly aware of the consequences of a misjudged footstep, but fearful only of being overtaken. Suddenly she hated her companions; her mind was in a furious revolt at their cowardice, their indecision, or whatever it was that held them like a group of wooden figures safe on shore while the man whose life was worth all theirs put together exposed himself to needless peril. That he was really in danger she felt sure. She knew that Murray was apt to lose himself in his dreams; perhaps some visionary mood had blinded him to the menace of that mounting ice-ridge it front of the glacier, or had he madly chosen to stand or fall with this structure that meant so much to him? She would make him yield to her own terror, drag him ashore, if necessary, with her own hands.

She stumbled, but saved herself from a fall, then gathered her skirts more closely and rushed on, measuring with instinctive nicety the length of every stride. It was not an easy path over which she dashed, for the ties were unevenly spaced; gaping apertures gave terrible glimpses of the river below, and across these ghastly abysses she had to leap.

The hoarse bursts of shouting from the shore ceased as the workmen beheld her flitting out along the steel causeway. They watched her in dumb amazement.

All at once O'Neil saw her and hurried to meet her.
