"Good!" cried Trot. "Now I can climb up."
"Don't you want me to go with you?" asked Button-Bright a little wistfully.
"No," said the girl. "You must stay to lead the army. And if you can think of a way, you must try to rescue us. Perhaps I'll be able to save Cap'n Bill by myself; but if I don't, it's all up to you, Button-Bright."
"I'll do my best," he promised.
"And here, keep my polly till I come back," added Trot, giving him the bird. "I can't take it with me, for it would be a bother, an' if it tried to spout po'try, I'd be discovered in a jiffy."
As the beautiful Witch kissed the little girl goodbye, she slipped upon her finger a curious ring. At once, Button-Bright exclaimed, "Why, where has she gone?"
"I'm right here," said Trot's voice by his side. "Can't you see me?"
"No," replied the boy, mystified.
Rosalie laughed. "It's a magic ring I've loaned you, my dear," said she, "and as long as you wear it, you will be invisible to all eyes, those of Blueskins and Pinkies alike. I'm going to let you wear this wonderful ring, for it will save you from being discovered by your enemies. If at any time you wish to be seen, take the ring from your finger; but as long as you wear it, no one can see you, not even Earth people."
"Oh, thank you!" cried Trot. "That will be fine."
