"You'll suffer for this!" whined Andy, getting to his feet, but taking care to retreat from Tom, who stood ready for him. "I'll get square with you for this! Jake, come on, and we'll get our guns!"
Andy turned and hurried back toward the shed, followed by the evil-looking man, who had apparently been undecided whether to attack Mr. Damon or Tom. Now the bully and his companion were in full retreat.
"We'll get our guns, and then we'll see whether they'll want to stay where they're not wanted!" went on Andy, threateningly.
"Bless my powderhorn! What had we better do?" asked Mr. Damon.
"I guess we'd better go back," said Tom calmly. "Not that I'm afraid of Andy. His talk about guns is all bluff; but I don't want to get into any more of a row, and he is just ugly and reckless enough to make trouble. I'm afraid we can't learn what we came to find out, though I'm more convinced than ever that Andy is using my plans to make his aeroplane."
"But what can you do?"
"I'll see Mr. Sharp, and send a protest to the aviation committee. I'll refuse to enter if Andy flies in a model of my Humming-Bird, and I'll try to prevent him from using it after he gets it on the ground. That is all I can do, it seems, lacking positive information. Come on, Mr. Damon. Let's get back to our hotel, and we'll start for home in the morning."
"I have a plan," whispered the odd man.
"What is it?" asked Tom, narrowly watching for the reappearance of Andy and the man.
"I'll stay here until they come, then I'll pretend to run away. They'll chase after me, and get all excited, and you can go up and look in the shed windows. Then you can join me later. How's that?"
