"Fleming was cold and shaking as he listened. 'Drive back along the road through the woods, Joshua'--he seldom called me by that name. 'I think something has happened to the old man. His knock is on duty tonight, but where is he?' "It came again, and following it a low cry from passage behind closed doors. 'She heard it too,' said Fleming. And he went to his wife. "I called up the landing-man to help me--Tommy Briscoe; I knew he wouldn't spread any talk about. The search was not long. A lantern burning by itself in the woods showed us where he had stopped the cart and half turned and tramped around in the snow. He'd dropped the bag out, probably, missed it and looked for it on foot, setting his lantern down. He'd gone back quite a bit along the road, and, coming back with it, the light in his eyes, he had made a misstep, and the shaft--the old Granite Hill shaft, you know--it's close to the road. We found him in the sump at the bottom. There had been too much rain, but it is a deep shaft anyway. He kept his hold on the bag, and he kept his senses long enough to hook it onto a poor little stray pine-root above the water, where he died. It was a cruel death, but his face was good to look at." "And the telegram?" I asked. "It was safe. He'd saved everything, except himself. They were driven over to Colfax that night, with not a moment to spare----" "But you haven't told me what it was."

I need you.'" "And they were in time?" "To bid her good-by," said Joshua. "There was no hope for her but in death. Of course, they never explained. She simply fled from--we don't know what. As long as she could she bore it without complaint, and then she came home. She had them both with her and she knew them. "I believe they were willing to give her up. It was the only solution left. They were very fixed in their ideas about divorce, and what comes after. They believed in staking all or nothing and abiding the result. The logic of her choice was death. They saw her free, without a stain, without an obligation in this life even to her child, for it lay dead beside her. They did grieve for that. They wanted it to live. It would have been something--yet, I believe, even that was best. "They lived on here for a while, if you call it living; but the silence in these rooms was more than she could endure. And I need not tell you that the watchman, who was put on after Gideon, had orders to leave that knocker alone." "And you think," I asked, "that while Gideon lay dead at the bottom of the shaft, his knock was 'marching on'?" I regretted instantly the turn of my last sentence. Joshua stiffened as he replied:
