It might or might not be. To the Colonel it was wonderful; in fact, so interesting that, what with the excellent meal of which he had partaken and this discussion, he quite forgot that experience when being swung upward to safety. Indeed, he must needs go off at once with Joe on a tour of investigation, while Andrew chatted with the Major.

"And so you determined to risk it," said the latter.

"Certainly! You couldn't expect us to leave the greater part of our number in the heart of that city!"

Andrew sauntered across to one of the wide-open windows of the saloon and pointed downward. Yes, there was Adrianople, a mere blotch beneath them, its outline dim and blurred, its streets and houses merged into one another; its trenches, its forts, its struggling defenders utterly obliterated. A black line, with dark clumps here and there, showed merely the presence of the attackers, while tiny and ridiculously dim points of fire betrayed the guns which even then were speaking.

"Listen! Yes," reflected Andrew, "we heard the guns from a distance, and, risking all, made our way back towards the city. And there we lay, almost at this elevation, while the sun slowly rose and flooded the place. Then we gradually dropped nearer and nearer to the houses."

"And no one saw you?" asked the Major.

"None, I believe. All were too engaged with the fighting. It was Alec, I suppose, who first caught sight of us, and Hawkins who saw his signal. After that, you know what happened. And now, Major, what becomes of 'Charlie'? You have been lucky enough to discover him, and one presumes that he has come aboard with his secret. Bear in mind that I hold this vessel at your disposal. If necessary we will return to England. Or we can set the Colonel down wherever he may think most convenient. But if time is of importance, and his destination is England, then I suggest that we make use of the aeroplane which we carry. Come and inspect it."

They tossed their cigar stumps out of the window, took one more look downward at the forlorn city, and then ascended to the wide deck carried on the top of the airship. Overhead, as they trudged along it, fluttered the long aerials suspended to the thin masts erected for wireless telegraphic purposes, while far down below, almost in the centre of the main gangway, a man could be seen bending over transmitter and receiver.

"You see, we are well equipped," said Andrew. "Of course, if it so happened that the Colonel could send his information by wireless, then it would be a great pleasure to have him with us. In any case, let us inspect Joe's aeroplane. Here it is; now, take close stock of it."
