"Well?" asked the Major, puffing out a cloud of smoke. "Your answer. I ask no favour. I have pointed out the risk."

"And I thank you heartily," cried Andrew. "Gentlemen, we will take the all-red route for this world tour, looking in at as many dependencies of the British crown as possible. And we will willingly take the risk of a visit to Adrianople. If there are any here who have no desire for this adventure, then we will set them down wherever they wish. Now, let us be moving."

It may be readily imagined that not one of those present in the brightly-lighted saloon had any qualms as to this projected visit, for to all of them was promised a novel situation. The Major and the Commander might hope, indeed, to witness a modern siege in actual operation, while no doubt the successful manœuvring of this fine vessel would be of sufficient interest to Joe and Andrew. For Dick and Alec there was, of course, a decided attraction in the suggestion.

"Who knows, there might be a rumpus of some sort," declared the former. "We might get to see a bit of the fighting. How'd you like that?"

"How'd you?" Alec grinned back at him. "You're the one to answer, for you're a man of war. You're in the Navy."

"I'll tell you. If there's just the merest chance of getting down into the city I mean to take it," said Dick. "Then there's no knowing what may happen. How is the Major going to find this fellow Charlie? That's what beats me, for Adrianople is a big city. And how is he to bring him or his news aboard without descending? I tell you this ship'll have to be steered right over the armies. She'll have to drop to easy distance of the city, and then—supposing a shell did happen to come our way—well——"

"You'd find yourself in the city precious quick, and so have your dearest wish fulfilled in a minute," laughed Alec. "We'd blow up, eh! There'd be a fine old crash on the roofs of Adrianople."

Joking apart, the danger was not likely to be small and the risk run by the crew of the airship was perhaps greater than had been anticipated. But Andrew and his nephew made light of any trouble, and indeed undertook this work with a keenness that did them credit. It followed, therefore, that within a dozen hours the airship floated high up above the besieged city. It was night-time, clouds floated thickly in the sky, while not a light showed aboard the vessel. Down below a few flickering lamps could be seen in the direction of the city, though the greater part was plunged in darkness. But away to the north and south, and on either hand, there were rows and rows of tiny blazing circles, the camp fires of the investors.

"Holding every outlet," said the Major. "Not a man can enter or leave the city. If they could, Charlie would have bade farewell to it long ago. But entrance from the air is another question altogether."

"And you propose to descend to the city?" asked Andrew.
