"We don't just know that," said Betsy, taking her hand; "but we're trying to find Shaggy's long-lost brother, who has been captured by the terrible Metal Monarch. Won't you come with us, and help us?"
Polychrome looked from one to another of the queer party of travelers and a bewitching smile suddenly lighted her face.
"A donkey, a mortal maid, a Rose Princess and a Shaggy Man!" she exclaimed. "Surely you need help, if you intend to face Ruggedo."
"No, indeed. Ruggedo's caverns are beneath the earth's surface, where no Rainbow can ever penetrate. But I've heard of the Metal Monarch. He is also called the Nome King, you know, and he has made trouble for a good many people--mortals and fairies--in his time," said Polychrome.
"Do you fear him, then?" asked the Princess, anxiously.
"No one can harm a Daughter of the Rainbow," said Polychrome proudly. "I'm a sky fairy."
"Then," said Betsy, quickly, "you will be able to tell us the way to Ruggedo's cavern."
"No," returned Polychrome, shaking her head, "that is one thing I cannot do. But I will gladly go with you and help you search for the place."
This promise delighted all the wanderers and after the Shaggy Man had found the path again they began moving along it in a more happy mood. The Rainbow's Daughter danced lightly over the rocky trail, no longer sad, but with her beautiful features wreathed in smiles. Shaggy came next, walking steadily and now and then supporting the Rose Princess, who followed him. Betsy and Hank brought up the rear, and if she tired with walking the girl got upon Hank's back and let the stout little donkey carry her for awhile.
At nightfall they came to some trees that grew beside a tiny brook and here they made camp and rested until morning. Then away they tramped, finding berries and fruits here and there which satisfied the hunger of Betsy, Shaggy and Hank, so that they were well content with their lot.
It surprised Betsy to see the Rose Princess partake of their food, for she considered her a fairy; but when she mentioned this to Polychrome, the Rainbow's Daughter explained that when Ozga was driven out of her Rose Kingdom she ceased to be a fairy and would never again be more than a mere mortal. Polychrome, however, was a fairy wherever she happened to be, and if she sipped a few dewdrops by moonlight for refreshment no one ever saw her do it.
