"Don't ask them why," said Shaggy earnestly. "I knew you would ask them why, but you ought not to do it. The reason is plain. Those stones are rubber; therefore they are not stones. Those rocks around us are rubber, and therefore they are not rocks. Even this path is not a path; it's rubber. Unless we are very careful, your Majesty, we are all likely to get the bounce, just as your poor officers and Tik-Tok did."
"Then let's be careful," remarked Files, who was full of wisdom; but Polychrome wanted to test the quality of the rubber, so she began dancing. Every step sent her higher and higher into the air, so that she resembled a big butterfly fluttering lightly. Presently she made a great bound and bounded way across the stream, landing lightly and steadily on the other side.
"There is no rubber over here," she called to them. "Suppose you all try to bound over the stream, without touching the stepping-stones."
Ann and her officers were reluctant to undertake such a risky adventure, but Betsy at once grasped the value of the suggestion and began jumping up and down until she found herself bounding almost as high as Polychrome had done. Then she suddenly leaned forward and the next bound took her easily across the brook, where she alighted by the side of the Rainbow's Daughter.
"Come on, Hank!" called the girl, and the donkey tried to obey. He managed to bound pretty high but when he tried to bound across the stream he misjudged the distance and fell with a splash into the middle of the water.
"Hee-haw!" he wailed, struggling toward the far bank. Betsy rushed forward to help him out, but when the mule stood safely beside her she was amazed to find he was not wet at all.
"It's dry water," said Polychrome, dipping her hand into the stream and showing how the water fell from it and left it perfectly dry.
"In that case," returned Betsy, "they can all walk through the water."
She called to Ozga and Shaggy to wade across, assuring them the water was shallow and would not wet them. At once they followed her advice, avoiding the rubber stepping-stones, and made the crossing with ease. This encouraged the entire party to wade through the dry water, and in a few minutes all had assembled on the bank and renewed their journey along the path that led to the Nome King's dominions.
