“That was what we feared,” said Jack, “and it bothered us to know what we ought to do. Circumstances settled it for us. You see, he was shut up below, with all that explosive stuff. If he believed we meant to hand him over to the British the chances were that, in a fit of desperation, he might have blown the boat up, and all of us would have perished with her.”

“And you made a bargain with him, did you, promising to let him go free on condition that he behaved himself? Well, my son, after all is said and done that seems to have been a wise move on your part. Zenos is a reckless scoundrel, and he knows what would happen to him if caught.”

The story had now been finished, and the boys eagerly waited to hear what the Territorial officer would have to say. He seemed to be considering matters, since he remained silent for quite some time.

“As I understand it, Amos,” he finally remarked, turning upon the other as he spoke, “you have good reason to believe this dashing brother of yours is now with our force out here at the Dardanelles?”

“We know he started this way, and the chances are ten to one Frank has been doing some of his usual daring work here. We watched the aeroplanes and seaplanes soaring over the Turkish forts and batteries while the fleet was bombarding in the lower part of the straits yesterday, and something seemed to tell me that the one who dropped bombs into a fort, and blew up the magazine, must have been my brother.”

“Very possibly,” agreed the other, with a smile, “although we have some gallant fliers of our own stock who would hesitate at nothing. Then your plan is to try and find out as soon as possible if Frank is here?”

“We were given to understand that possibly one or more of the aviators had found a convenient base on the peninsula, though the main body had their headquarters on one of the Greek islands some twenty miles or more away from here. What we planned to do was to first of all learn whether Frank could be the one ashore, as that would just be like his venturesome ways; if it turned out to be another flier, then the Vice-Admiral told us to get back to the Thunderer as soon as we could, and he would send us to the island.”

The Colonel was rubbing his chin after the manner of a man who might be trying to figure something out. Feeling sure that he would do everything possible to further their cause, the boys waited patiently to hear what he might have to say when his mind was made up.

“I have been given to understand,” he finally told them, “that there is one of our aviators who has found some place where he can drop down and rise again, on the shore of Gallipoli; but I am sorry to say I have not myself seen him. I made inquiries only yesterday and one of my men, who has been at the camp of the New Zealanders a mile or more above us, told me he had seen and talked with the birdman. So I understand that he is taking advantage of the protection they are able to give him. The ground must differ radically from what we have here, because outside of one little exposed plateau there is absolutely no place an aeroplane could make a run to get a start when about to rise.”

Amos looked pleased.
