Then came another message from Doctor Atwood. The nurse followed his directions and once more hope came back to the Salper home. The patient rallied, stirred, and for that time at least, the danger was past.

So dawn came at last and Joe and the two younger boys went back to their cottage to try to catch a few hours of sleep. Bob remained at the station, declaring that he felt not at all tired and as soon as the other boys had rested they could come to his relief.

A hard vigil that for Bob. In spite of all he could do, his head would nod and his heavy eyelids close, to be jerked open next moment by the arrival of some one from the Salper home or a message from Doctor Atwood.

News of the struggle had spread all over Mountain Pass, and people watched with admiration and interest the brave fight that was being made for a woman’s life. And sometimes it seemed that, despite all their efforts, the struggle must end in failure.

All that day the battle waged and the next night—the boys taking turns at the radio board, untiring in their determination not to lose. And Doctor Atwood was as determined as they.

And then, on the morning of the second day came news that the patient had passed the much-dreaded crisis and, with the most careful nursing, was sure to recover.

“She’ll be all right now,” came Doctor Atwood’s cheery voice. “It’s been a hard pull, but she’s past the danger point now. Keep in touch with me, boys, so that, in case of a relapse, I can tell you what to do.”

Joe turned to the boys with the light of pride and affection in his eyes.

“That’s some dad I’ve got!” he said.

Later, when the boys walked over to the Salper home to offer congratulations, the girls received them with literally open arms.
