The parade was almost in readiness for the start when Matt, McGlory, and Ping reached the aëroplane. Hostlers were running about placing plumes in the head-stalls of the horses, drivers were climbing to their seats, the wild animal trainer was getting into the open cage, and the members of the band were tinkering with their instruments.
Haidee was standing by the aëroplane when Matt, McGlory, and Ping reached the machine.
"All ready, Haidee?" asked Matt.
The girl turned and looked at him blankly. Her face was unusually white, and there was a vacant stare in her eyes.
"What's to pay, sis?" asked McGlory, with a surprised look at Matt. "Don't you feel well?"
"I am well."
The words came in an unnatural voice and with parrot-like precision.
Boss Burton came hustling down the line in his runabout.
"Hurry up, Matt," he called. "Help Haidee to a place on the upper wing of the Comet."
Matt stepped over to the runabout.
