Through the woods and across a swamp he pulled himself along, and at last, in the afternoon, as he could tell by the sun, he dragged himself out on a road and saw a white farmhouse a little way down it.

“I—I guess I’m all right now,” faltered the exhausted youth.

“Come in,” the man invited. “Looks to me like you’d better telephone for a doctor while you’re at it!”

“That can wait,” gasped Tom. “Something else is more important. Show me the telephone!”

A little later he was gasping to Ned his message:

“Just escaped! Watch the plant! Get Father to safety. Look out for bombs. I’ll try——”

Then Tom Swift fell over in a faint.
