Amos only too gladly complied. He fairly held his breath while the stiffened figure of the private put out a hand and took the photograph. He was looking intently at it now.

“That picture was taken, they tell me, several years back, Lancing,” the Colonel went on to explain, “so naturally it might not be exactly like the original as he is today. Now, since you have examined it, can you say whether the man you met and talked with resembled this picture to any degree?”

“He does, sir, and he does not,” answered the man.

“Still you can see no reason why they should not be the same, can you? Is the color of the hair similar, and the general features much alike?” continued the obliging officer.

“On the whole, sir, I’m tempted to say I have talked with the original of this picture,” the soldier finally admitted. “Yes, I can see now the odd little smile around the corners of the mouth that I noticed in the air pilot.”

Amos gave a gurgle of intense satisfaction. It seemed to him that, as Jack had declared, their third attempt was fated to meet with the success that had been denied to them on two previous occasions.

“That will do, Lancing. When you go back send the Greek Arturus to me. Tell him it is a matter of great importance.”

He turned to the boys after the soldier had again saluted, wheeled stiffly in his tracks, and walked away in a machine-like fashion.

“It begins to look promising, I am glad to note, Amos, and I sincerely hope you will be able to find your brother before another daybreak. Though, like others you have told me of, I am sorry to know you mean to coax him to leave us, in order to go home. I only trust that after he has seen his father he will come back again and continue his wonderful work for our cause.”

The Greek must have been close at hand for he now made his appearance. Jack was favorably impressed with his bold, resolute bearing. He likened him to some of those old-time worthies of whose brave exploits history teems; and whose names are held in reverence wherever Greeks continue to gather, for they live a good deal in the past.
