In the distance a beautiful island covered with palm trees and flowers beckoned invitingly from the sparkling water. Nothing can possibly go wrong now, cried the Humbug happily, and as soon as he'd said it he leaped from the car, as if stuck by a pin, and sailed all the way to the little island. And we'll have plenty of time,'' answered Tock, who hadn't noticed that the bug was missing--and he, too, suddenly leaped into the air and disappeared. It certainly couldn't be a nicer day, agreed Milo, who was too busy looking at the road to see that the others had gone. And in a split second he was gone also.";
