Then he had struck the great white needle, and was crashing into the delicate apparatus below it. Waves of pain beat upon his mind like flashes of blinding light. But his last mental image, as he passed into oblivion, was a picture of Helen's face. Oddly, it was not her face as he had last seen it, but a reproduction of the old newspaper half-tone, curiously retouched with life and color.


here is little more to tell. It was some weeks later when Dan came back out of a world of delirium and dreams, to find himself lying on his back in a tent, very much bandaged. He was alone at the moment, and at first could not recall that tremendous last day of his conscious life.

Then he heard a thrillingly familiar feminine voice calling "Kitty, kitty, kitty." He tried to move, a dull pain throbbed in his breast, and a groan escaped him. In a moment Helen appeared; the gray kitten was forgotten. She looked very anxious and solicitous—and also, Dan thought, very beautiful.

"No, no!" she cried. "You are going to be all right! Dad made me learn a little elementary medicine before we came here, and I know. But you mustn't speak! Not for days yet! I'll have to guess what you want. And you can wink when I guess the right thing.

"Gee, but I'm glad you've come to! You'll be as well as ever, pretty soon. The kitten was lots of comfort. Still—"

Dan attempted to move. She leaned over him, shifted his weight and smoothed the sheet with strong, capable hinds. "You want to know about what happened to the machine monsters?"

He winked.

"Well, you remember when they found us, and shot the green ray at us. They left you there—I thought you were dead—and carried me up here on the hill. Perhaps they wanted me for a laboratory subject to test the green ray on, or something of the kind. Anyhow, they carried me into a big shed filled with strange machines.
