Woot sat up and gazed around him in amazement.
"I—I don't know!" he replied.
The two tin men, arm in arm, started to pass them when both halted and tumbled, with a great clatter, into a heap beside Woot. Polychrome, laughing at the absurd sight, came dancing up and she, also, came to a sudden stop, but managed to save herself from falling.
Everyone of them was much astonished, and the Scarecrow said with a puzzled look:
"I don't see anything."
"Nor I," said Woot; "but something hit me, just the same."
"Some invisible person struck me a heavy blow," declared the Tin Woodman, struggling to separate himself from the Tin Soldier, whose legs and arms were mixed with his own.
"I'm not sure it was a person," said Polychrome, looking more grave than usual. "It seems to me that I merely ran into some hard substance which barred my way. In order to make sure of this, let me try another place."
She ran back a way and then with much caution advanced in a different place, but when she reached a position on a line with the others she halted, her arms outstretched before her.
"I can feel something hard—something smooth as glass," she said, "but I'm sure it is not glass."
