was refilled. As soon as it was sufficiently inflated, the Wondership
sailed over to the road and was brought down alongside the still
unconscious man.

"Looks as if he's badly hurt," said Tom with some anxiety.

"It does. His skull may be fractured," agreed Jack. "If he is
seriously injured those fellows may get into trouble."

It required all the boys' strength to raise the man and get him into
the Wondership. Here they laid him out on the floor of the rear
section. They had just done this when the red light signaled Jack
again. It was Mr. Chadwick. He had notified the Nestorville police
force, consisting of a chief and two men, and they were on the lookout
for the offending auto.

"Good," said Jack. "Say, dad, the radio telephone has shown its
usefulness on the first day out, hasn't it?"

They were soon in the air once more. The run to Nestorville was made
quickly. On the outskirts of the town they came to earth and deflated
the balloon bag, since the hospital stood in a group of trees and it
would have been impossible to make a landing there. The Wondership was
converted into an auto and sent speeding toward the main street of the
village.

Suddenly they heard a whir of wheels behind them and an impatient
tooting of a horn. They looked back and uttered a simultaneous cry of
astonishment.
