"Look," said Sherman, "there's Chicago now. But what's that? No, there, along the lake front."
Following the direction of his pointing finger they saw something moving vaguely along Lake Shore Boulevard; something that might be a car—or a man!
"Let's go down and see," offered Ben.
"O. K. chief, but we've got to pick a good landing place for this tub. I don't want to get her marooned in Chicago."
The explosions were cut off, the wings extended, and Sherman spiralled carefully downward to the spot where they had seen the moving object. With the nicety of a magician, he brought the ship to a gliding stop along the park grass, and followed by the rest, Ben Ruby leaped out. The edge of the drive was a few yards away. As they emerged from the ship no one was visible, but as they walked across the grass, a figure, metallic like themselves, and with a gun in one hand, stepped from behind a tree.
"Stand back!" it warned suspiciously. "Who are you and what do you want?"
"Conversation with sweet-looking gentleman," said Yoshio politely, with a bow.
"Why, we're members of the American air force," said Ben, "cooperating with the federated armies against the Lassans, and we were on an exploring expedition to see if we could find any more Americans."
"Oh," said the figure, with evident relief. "All right, then. Come on out, boys."
