"We'll try to run down to your camp to see you," promised Jack. "We'll send you a line beforehand."
The twins and their distinguished cousin were now on their feet.
"Make it soon, then," stipulated Jimmy:. "We think we're going to start for the front before long. 509th Infantry's ours, you know. You won't have much trouble finding us."
"If it happens that we don't see you again there, we'll hope to meet you somewhere back of the firing line," declared Schnitzel earnestly. "I've surely enjoyed meeting the Twinkle Twins.
"And you, sir." He turned to Voissard. "It has been a great honor to me to shake your hand."
"Merci. I have also much enjoyed this hour with my American Allies," responded Voissard graciously.
He offered his hand to Schnitzel, then in turn to each of the other four Brothers, all of whom expressed their warm pleasure of the meeting.
Jimmy came last. As the two men clasped hands their eyes again met and again exchanged that silent message of friendliness. A general hand-shaking with the Twinkle Twins followed, then the Khaki Boys said a last good-bye and left the restaurant.
"Shall we walk or hail a taxi?" asked Bob, as they stepped out into the street. "The full moon is on the job to-night. We can see our way along even though this burg is shy on street lights."
Since the beginning of the war Paris had shown few street lights after nightfall. Due to the fiendish Boche practice of making nocturnal air raids for the purpose of dropping bombs, principally upon defenseless women and innocent little children, every possible precaution had been taken to guard this city against the inhuman cruelty of an ignoble foe.
