watch as he
could on Lieutenant Secor. However, the attitude and conduct of the
Frenchman seemed to be above suspicion. He did not carry out his
intention, if he really had it, of seeking permission from the
commanding officer to observe more closely the work of Blake and Joe.
And for a few days before the last of the new films had been taken the
blue-uniformed officer was not seen around the camp.

Blake and Joe were too busy to ask what had become of him. Then, too,
other matters engaged their attention. For a letter came from Mr.
Hadley, telling them and Charles to hold themselves in readiness to
leave for England at any time.

"It's all settled," wrote the producer. "I have signed the contracts to
take moving picture films of our boys in the French trenches, and
wherever else they go on the Western front. You will get detailed
instructions, passes, and so on when you arrive on the other side."

"When do we sail?" asked Joe, after Blake had read him this letter, and
when they were preparing to go back to New York, having finished their
army camp work.

"The exact date isn't settled," answered his partner. "They keep it
quiet until the last minute, you know, because some word might be
flashed to Germany, and the submarines be on the watch for us."

"That's so!" exclaimed Joe. "Say, wouldn't it be great if we could get
one?"

"One what?" asked Blake, who was reading over again certain parts of Mr.
Hadley's letter.

"A submarine. I mean film one as it sent a torpedo to blow us out of the
water. Wouldn't it be great if we could get that?"

"It would if the torpedo didn't get us first!" grimly replied Blake. "I
guess I wouldn't try that if I were you."

"I'm going to, if I get a chance," Joe declared. "It would make a great
film, even a few feet of it. We could sell it to one of the motion
weeklies for a big sum."

"It's hardly worth the risk," said Blake, "and we're going to have
plenty of risks on the other side, I guess."

"Does Mr. Hadley say how we are to go?" asked Joe.

"From New York to Halifax, of course, and from there over to England.
They search the ship for contraband at Halifax, I believe, or put her
through some official form.

"From England we'll go to France and then be taken to the front. Just
what will happen when we get on the other side nobody knows, I guess.
We're to report at General Pershing's headquarters, and somebody there,
who has this stunt in hand, will take charge of us. Af
