"Why do you have such great confidence in his coming?" asked John.
"He inspires confidence, when you see him, and there's his reputation. I've an idea that he'll be carrying dispatches between the two wings of the French army, dispatches of vast importance, since the different French forces have to cooperate now along a line of four or five score miles. Of course the telephone and the telegraph are at work, too, but the value of the aeroplane as a scout and dispatch bearer cannot be over estimated."
"One is coming now," said John, "and I think it has been attracted by our flag. I take it to be German."
"Then we'd better keep very close. Still, there's little chance of our being seen here, and the aviators, even if they suspect a presence, can't afford to descend, leave their planes and search for anybody."
"I agree with you there. One can remain here in comparative safety and watch the results of our signal. That machine is coming fast and I'm quite sure it's German."
"An armored machine with two men and a light rapid fire gun in it. Beyond a doubt it will circle about our tree."
The plane was very near now, and assuredly it was German. John could discern the Teutonic cast of their countenances, as the two men in it leaned over and looked at the flag. They dropped lower and lower and then flew in circles about the tree. John, despite his anxiety and suspense, could not fail to notice the humorous phase of it. The plane certainly could not effect a landing in the boughs, and if it descended to the ground in order that one of their number might get out, climb the tree and capture the flag, they would incur the danger of a sudden swoop from French machines. Besides, the flag would be of no value to them, unless they knew who put it there and why.
"The Germans, of course, see that it's a French flag," he said to Weber. "I wonder what they're going to do."
"I think they'll have to leave it," said Weber, "because I can now see other aeroplanes to the west, aeroplanes which may be French, and they dare not linger too long."
"And our little flag may make a big disturbance in the heavens."
