In a few moments Matt was again on the ground. The roll, which Carl immediately handed to him, he found to contain a number of sheets wrapped compactly in a piece of white paper.
"I guess we'll open it and not stand on any ceremony," said Matt.
"Sure!" exclaimed Carl. "For vy nod?"
"It's not exactly the right thing to do. They're not our papers and we haven't any business tampering with documents that belong to some one else. Under the circumstances, though, and considering that the whole affair of the air-ship is a strange one, and that we may be able to help the two men in some way through the information the roll may contain, we'll have a look at it."
Going back to the place where they had eaten their lunch, the boys sat down and Matt opened the little bundle. A dozen blue prints of mechanical tracings were revealed. In the center of the roll was a sealed envelope, bearing no address or writing of any sort.
"Dere's nodding aboudt der plue prints to helup us know somet'ing," said Carl. "Oben der enfellup, Matt."
"No," returned Matt, "we can't do that. That would be going a little too far."
"Vell, ve got to do somet'ing oof ve findt oudt who dose fellers vas."
"We'll wait, and give them a chance to claim their property."
"How dey vas going to glaim it, hey? Dey didtn't dell us who dey vas, und ve ditn't dell dem our names."
