“Name it,” urged Billy.

“In the bastion at the extreme right of the west rampart of the inner fort is a loose stone, rough-faced, and marked by powder burn, cross shape. The stone can be moved with knife blade. Behind it you will find a moleskin belt, containing a decoration of great value to me and mine; a ruby-set sword hilt of far more value to a jeweler; a packet of letters, and several roleaux of gold. I would that you could accept the gold without danger, owing to its place of minting, but otherwise I pledge you to deliver this belt to the man, Fritz, at the Steiber Coffee House. Say to him, ‘It is for Eitel,’ and you will have fulfilled your promise.”

“What if there are no ‘Fritz’ and no ‘Coffee House’?”

Billy spoke like the critic of a contract.

“In that case,” wearily stated Stanislaws, “return the belt to the place I left it. In no event must you assume any further risk.”

“I don’t see why you didn’t get away in your aeroplane when you saw the jig was up. You could have done it with honor.”

Henri could not suppress his regret over this lost chance on the part of the Austrian.

“That was officially suggested to me more than once in the fort just before the storm broke,” said Stanislaws, “but the idea did not appeal to me. My duty was to sink or swim with the balance.”

It was not remarkable that the boys should be permitted to hold such lengthy converse with the prisoner, for as the companions of the noted scouts from headquarters they roved without hindrance, and, besides, had not the Muscovite troops themselves, but a short time previous, cheered the unarmed Austrians after their parade out of Przemysl?

That Salisky and Marovitch finally interrupted the interview was not a move of official interference, but due only to the emergency of their travel plan. The scouts attributed the interest taken by the lads in the trooper under guard solely to the fellowship of airmen.
