"One teaspoonful only for you, Fuller," he announced as he rejoined his comrades with the spoils. "Raw spirit will play the deuce with that wound of yours."

"You are quite right," agreed the flight-lieutenant as Barcroft proceeded to prise open the meat tin. Its contents consisted of tightly packed sausages. "For the same reason I suppose I must abstain from rich food. Give me a biscuit, you despoiler of the dead."

Late in the afternoon another party of Germans arrived upon the scene, this time merely to collect the victims of the gas and to remove the instruments of retribution.

"Double patrols at all cross-roads to-night, curse it!" said one of the soldiers. "Always more work. These Englishmen must be stiff by this time. Why send us out to arrest corpses?"

"We don't know that the gas has settled them," replied his companion. "Although it did the trick very neatly for Johannes Muller. I'm sorry for him. As for the ober-leutnant——"

He shrugged his shoulders expressively. Evidently the officer was a typical Prussian.

"These English airmen played the deuce at Aerschot and Lierre," continued the first speaker. "It will go badly with them if they're caught, but, as I said, it's my opinion that they are done for already. Double patrols on a night like this. It's as bad as the trenches at Ypres."

"Fortunately I am warned for the Golden Lion cross-roads," said his companion. "As soon as the leutnant has made the rounds our party will make tracks for the cabaret. I am an old campaigner, Fritz."

"Ach! Do not, then, get caught," cautioned the other as he slammed the lid of the box on the cart. "It will be safe enough between midnight and two o'clock. I've a mind to join you, only it's a goodish step from Quatre Vents."

"Where's the map?" inquired Fuller, after the fatigue party had disappeared. "The 'Golden Lion' he said? That's it—le Lion Doré—it's marked here. Luck, boys! It's on the way to the frontier. Roll on, eleven o'clock. Only six hours more. Why didn't we bring a gramophone, or even a pack of cards?"
