CHAPTER III
BY AEROPLANE ACROSS THE BORDER

When the leader of the Eagle Patrol made this astounding assertion both of his friends betrayed additional interest. Indeed, it was a question whether Andy or Tubby, by the rapt expression on their faces, showed the greater excitement.

Tubby had one great advantage over his comrade. He had been abroad with Rob and Merritt Crawford, and had watched aeroplane pilots, both of the Allies and the Germans, shooting like meteors across the skies, bent on their work of learning what was going on back of the enemy’s lines so as to give points to those who handled the monster guns far in the rear, allowing them to drop their shells exactly where most wanted.

“Well, to think of the nerve of that fellow!” exclaimed the indignant Andy. “He snaps his fingers at the proclamation of the President about all true Americans standing for strict neutrality. Why, he’s meaning to give those Canucks the best chance ever to protest and claim damages from our Government. Isn’t that a fact, Rob?”

“Just what it is, Andy,” replied the scout master, watching the course of the small object so far up in the air that it resembled a giant bird.

“If they blow up a bridge, and wreck a train loaded with millions of dollars’ worth of stuff, and it’s proved that the scoundrels passed over from our side of the border, Uncle Sam will have to pay the whole bill?” questioned Tubby, now becoming aroused in turn.

“No doubt of it, if the proof is forthcoming,” Rob assured him serenely, since he knew enough of treaties and international law for that.

“Then anything that’s done against Canada from our side is really a blow aimed at our own country?” questioned Andy, beginning to show signs of anger. “Why, if it stands that way, then those conspirators are just as bad as if they were trying to knock a big hole in the U. S. Treasury, from which untold oodles of money could drop out. They’re breaking the neutrality laws smack. I’d like to let ’em know just what I think of such sneaks. There ought to be some way to detect and punish such backhanded knockers.”

“Oh, there are plenty of ways!” asserted Rob. “The law is stern enough, if you only can catch them in the act. There’s the rub. They take all sorts of precautions to hide their identity. Who could recognize that chap up a mile or so from the earth? How does any one know that he’s meaning to drop lower presently, so as to take a lot of pictures of the railroad where it passes over a bridge or trestle?”

“Is that the way it’s done?” ejaculated the deeply interested Andy, who was more or less ignorant of how air pilots make themselves so useful in war times.
