hampered vision. Then Jimmy closed his strained orbs, and when he
opened them again his vision was nearer normal.

"Do you see it yet?" whispered Bob. "Squint along my finger."

Jimmy did so.

"You have pretty good eyes to see anything in this blackness," he was
saying when he suddenly became aware of something moving out there
among the holes caused by the American shells.

It was more, he said afterward, as though part of the darkness itself
moved rather than that he actually saw something. But it was enough to
direct his attention to what Bob pointed out.

"It _is_ something," was Jimmy's cautious declaration. "And coming
this way!"

There was a movement on the part of Bob, and his chum knew he was
getting his rifle in readiness. Jimmy followed this example. They were
on the alert.

"Don't fire until you challenge," cautioned Jimmy. "It might be one of
our fellows, you know."

"One of our fellows--out there? How could it be!"

"Might have advanced too far, been wounded and have waited for
darkness to crawl back to our lines. Wait a second more until we see
what he's up to."
