The first two times there was no explosion as he swung the delicate wooden blades about, but the third time the engine started off with a roar, and a succession of explosions that were deafening, until Tom switched in the muffler, thereby cutting down the noise. Faster and faster the propeller whirled about as the motor warmed up, until the young inventor exclaimed:
"That's the stuff! She's better than ever! Climb up Ned, and we'll start off. You can turn her over, Rad; can't you?"

The two youths had scarcely taken their seats, and the colored man was about to twist around the fan-like blades of the big propeller in front, when from behind there came a hail.
"Hold on there! Wait a minute, Tom Swift! Bless my admission ticket, don't go! I've got, something important to tell you! Hold on!"
"Humph! I know who that is!" cried Tom, motioning to Eradicate to cease trying to start the motor.
