And he travelled far and he travelled fast, and he travelled east and west, north and south, over hills, and dales, and valleys, and mountains, and woods, and sheepwalks, but never a sign of the missing castle did he see. Now at last he came to the palace of the King of all the Mice in the Wide World. And there was a little mousie in a fine hauberk and a steel cap doing sentry at the front gate, and he was not for letting Jack in until he had told his errand. And when Jack had told it, he passed him on to the next mouse sentry at the inner gate; so by degrees he reached the King's chamber, where he sate surrounded by mice courtiers. Now the King of the Mice received Jack very graciously, and said that he himself knew nothing of the missing Castle, but, as he was King of all the Mice in the whole world, it was possible that some of his subjects might know more than he. So he ordered his chamberlain to command a Grand Assembly for the next morning, and in the meantime he entertained Jack right royally. But the next morning, though there were brown mice, and black mice, and grey mice, and white mice, and piebald mice, from all parts of the world, they all answered with one breath: "If it please your Majesty, we have not seen the missing Castle." Then the King said, "You must go and ask my elder brother the King of all the Frogs. He may be able to tell you. Leave your horse here and take one of mine. It knows the way and will carry you safe." So Jack set off on the King's horse, and as he passed the outer gate he saw the little mouse sentry coming away, for its guard was up. Now Jack was a kind-hearted lad, and he had saved some crumbs from his dinner in order to recompense the little sentry for his kindness. So he put his hand in his pocket and pulled out the crumbs. "Here you are, mousekin," he said. "That's for your trouble!" Then the mouse thanked him kindly and asked if he would take him along to the King of the Frogs. "Not I," says Jack. "I should get into trouble with your King." But the mousekin insisted. "I may be of some use to you," it said. So it ran up the horse's hind leg and up by its tail and hid in Jack's pocket. And the horse set off at a hard gallop, for it didn't half like the mouse running over it. So at last Jack came to the palace of the King of all the Frogs, and there at the front gate was a frog doing sentry in a fine coat of mail and a brass helmet. And the frog sentry was for not letting Jack in; but the mouse called out that they came from the King of all the Mice and must be let in without delay. So they were taken to the King's chamber, where he sate surrounded by frog courtiers in fine clothes; but alas! he had heard nothing of the Castle on golden pillars, and though he summoned all the frogs of all the world to a Grand Assembly next morning, they all answered his question with: "_Kro kro, Kro kro_" which every one knows stands for "No" in frog language.
