o. Cover your head when you feel that."

"Thanks!" murmured Blake, for he and his chums understood that the
soldier and his mates had saved their lives.

Now that the moving picture boys were out of danger and could take some
stock of themselves and their surroundings, their first thoughts,
naturally, were of their apparatus.

"Did they get our machines?" asked Joe.

"No; we saved the cameras for you," answered Drew.

"What about the boxes of exposed film--the ones the War Office is so
anxious to get?" asked Blake.

"I didn't see anything of them," said the soldier. "We were too anxious
to get you out of the gas and save the cameras to think of anything
else. I didn't see any boxes of films, but I'll ask some of the boys who
helped me."

Blake and his chums waited for this information anxiously, and when it
came it was a disappointment, for no one knew anything of the valuable
reels.

"Though they may be there yet," said Drew. "There was some fierce
fighting around that shell crater where we carried you from, but it's
within our lines now, and maybe the boxes are there yet. Better go and
take a look."

This Blake, Joe and Charlie lost no time in doing. After a little
search, for the character of the ground had so changed by reason of the
shell fire they hardly knew it, the boys located the place where they
had so nearly succumbed. They found the spot where their cameras had
been set up, for they were marked by little piles of stones to steady
the tripods. But there were no boxes of films.

"Gone!" exclaimed Blake disconsolately, as he looked about. "And we'll
perhaps never get another chance to make such pictures again!"

"It surely is tough luck!" exclaimed Joe.

They saw a sentry on guard, for this place was far enough from the lines
of both forces to obviate the use of trenches.

"What are you looking for, Buddies?" asked the soldier, who knew the
moving picture boys.

"Some valuable army films," explained Blake, giving the details.
"They're very rare, and we'll probably never get any others like them."

"Did you leave them here?"

"Right around here," answered Joe. "I think just near this pile of
rocks," and he indicated the spot he meant.

"Say, now," exclaimed the American private, "I wouldn't be surprised but
what those two fellows took 'em!"

"What two fellows?" cried Blake.

"Why, just as I was coming on duty here I saw two fellows, one dressed
as a German soldier and the other in a blu
