And now something new was added to his vast discomfort. Tiny twinges of pain, like small electric shocks, began shooting up his legs, increasing in intensity with each step he took. The pain built up until the rusty taste of blood in his mouth told him that he had bitten into the flesh of his lower lip.

Johnson's only consolation now was the thought that the man ahead of him must be suffering worse than he. At each step the pain increased its tempo, and the sound within his head grew to a battering roar. Although he felt himself at the last frayed ends of his vitality, he managed to stagger on.

Abruptly he realized that he had very nearly overtaken the man ahead. Through eyes glazed with pain, he saw the other, still standing, but swaying with agony and sickness. The man seemed to be gathering his resources for some supreme effort.

He tottered ahead two more steps, threw himself forward—and disappeared!

If he paused now, Johnson knew he would never be able to move again. Only will power and momentum carried him on. He stumbled and pitched forward. A searing pain traced a path through his head and he felt himself falling.


e was certain that he had never lost consciousness. The ground came up to meet him, and, with a last effort, he twisted his right shoulder inward. His cheek slid along the dirt and he lay on his side without strength. His legs pushed forward in a steady jerking movement as he fought to quiet his quivering muscles.

Gradually a soothing lethargy bathed Johnson's body. His pains vanished, and the sickness left his stomach.

But something was wrong—terribly wrong!
