Meanwhile a doctor was sent for. He quickly came, and after an hour’s hard work succeeded in bringing Delbier around all right.

Leo’s wonderful nerve was much commented upon.

“He’s a plucky chap,” said Pomeroy, the head of the tumblers, and all agreed with him.

Delbier was very thankful to our hero for what he had done for him, and from that day he was added to Leo’s growing list of friends.

About this time the “Greatest Show on Earth” was joined by a balloonist named Professor Ricardo, and his assistant, Larry Greson. The professor gave ascensions in the afternoon, previous to the circus performance, and thereby attracted large crowds.

Professor Ricardo was a jovial sort of fellow and he and Leo were soon on good terms.

“How would you like to go up some day with me, Dunbar?” he asked one afternoon.

“First-rate.”

“It’s a peculiar sensation when you go up for the first time.”
