"Only midnight!"

The steersman gave a weary yawn and turned back to his wheel. Inwardly Marian echoed his discouraged word. It seemed to her that she had crouched for years in the stern of the crazy little motor-boat. Rain and spray had drenched her to the skin. She ached in every half-frozen bone. Yet she sat, wide awake and alert, watching her pilot keenly.

He was a poor helmsman, she thought. However, an expert would have found trouble in taking an overloaded launch up-stream against that swollen current and in pitch darkness. Worse, the weight of the heavy dredge-bail weighed the launch down almost to water level. Every tiny wave splashed over the gunwale. Marian bailed on mechanically.

She had had hard work to bribe the owner to risk the trip up-stream. The men at Grafton had warned her, moreover, that she was running a narrow chance of swamping the launch, and thus of losing her precious piece of machinery, to say nothing of the danger to her own life. But all Marian's old timidity had fled, forgotten. Nothing else mattered if just she might serve her brother in his supreme need.

Through these four dreary hours the old commodore's quaint, frank words had echoed in her mind. And the commodore had been right, she owned, with a quiver of shame. Always, since their mud-pie days, Rod had done his part by her in full measure, generously, lovingly. Never, until these last days, had she even realized what doing her own part by Roderick might mean.

"Although I have been slower than my blessed old Slow-Coach himself in realizing what my life ought to count for. Well, as the commodore said, I have waked up at last. And mind this, Marian Hallowell! You stay awake! Never, never let me catch you dozing off again!"

"There's the camp light yonder," the steersman spoke at last, with a sigh of satisfaction.

Marian peered ahead through the cold, blinding mist. Away up-stream shone a feeble glimmer, then a second light; a third.

"Good! And—there are the dredge search-lights! Only a minute more and we'll be there."

Only a minute it seemed till the launch wheezed up to the landing and swung with a thud against the posts. Marian stumbled ashore.
