“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.  After that it’s up to you and Charles and me, Joe.”

“Yes, I suppose it is.  Well, we’ll do our best!”

“Sure thing!” assented Blake.

“We will if some ninny of a frog-skinning Frenchman doesn’t try to ram us with an airship!” growled Macaroni.  He had never gotten over the accident.

“I believe you are growing childish, Mac!” snapped Blake, in unusual ill-humor.

The last of the army camp films had been made and sent in safety to the studios in New York, where the negatives would be developed, the positives, printed by electricity, cut and pasted to make an artistic piece of work, and then they would be ready for display throughout the United States, gaining recruits for Uncle Sam, it was hoped.

Blake and Joe said good-bye to the friends they had made at the Wrightstown camp, and, with Macaroni, proceeded to Manhattan.  There they were met by Mr. Hadley, who gave them their final instructions and helped them to get their outfits ready.

“We’ll take the regular cameras,” said Blake, as he and Joe talked it over together, “and also the two small ones that we can strap on our backs.”

“Better take the midget, too,” suggested Joe.

“That’s too small,” objected the lanky helper.  “It really is intended for aeroplane work.”

“Well, we may get some of that,” went on Joe.  “I’m game to go up if they want me to.”

“That’s right!” chimed in Blake.  “I didn’t think about that.  We may have to make views from up near the clouds.  Well, we did it once, and we can do it again.  Pack the midget, Charlie.”
