"What's the trouble now, I wonder?"
"Hey, stop the airship! Stop them! Stop them!" yelled the strident voice of a man coming pell mell down the ravine path. He was in a frantic state of excitement and waving his arms wildly.
"Don't lose a second," spoke Dawson quickly.
Jerry gave the starter a whirl. Dave noticed that his father was quite excited and kept watching the advancing runner.
"Stop them, I tell you!" yelled this individual whom Dave recognized as one of the three individuals left behind at the hut with the other bundle.
"What for?" shouted one of the two men near the airship.
"Robbers-thieves! That bundle they gave us!"
"What about it?"
"No silks—nothing but a lot of worthless truck. They've cheated us and are making away with the real plunder."
Whiz! up went the airship. The three men ran after it. The newcomer shook his fist vengefully after the machine. The other two picked up rocks and hurled them in its wake.
