Trot watched from the window the escape of Ghip-Ghisizzle but did not know, of course, who it was. Then, after the City had quieted down again, she lay upon the bed without undressing and was sound asleep in a minute.  
The blue dawn was just breaking when she opened her eyes with a start of fear that she might have overslept, but soon she found that no one else in the palace was yet astir. Even the guards had gone to sleep by this time and were adding their snores to the snores of the other inhabitants of the Royal Palace. So the little girl got up and, finding a ewer of water and a basin upon the dresser, washed herself carefully and then looked in a big mirror to see how her hair was. To her astonishment, there was no reflection at all; the mirror was blank so far as Trot was concerned. She laughed a little at that, remembering she wore the ring of Rosalie the Witch, which rendered her invisible. Then she slipped quietly out of the room and found it was already light enough in the corridors for her to see all objects distinctly.
 
After hesitating a moment which way to turn, she decided to visit the Snubnosed Princesses and passed through the big reception room to the sleeping room of Indigo. There this Princess, the crossest and most disagreeable of all the disagreeable six, was curled up in bed and slumbering cozily. The little blue dog came trotting out of Indigo's boudoir and crowed like a rooster, for although he could not see Trot, his keen little nose scented her presence. Thinking it time the Princess awoke, Trot leaned over and gave her snub nose a good tweak, and at once Indigo sprang out of her bed and rushed into the chamber of Cobalt, which adjoined her own. Thinking it was this sister who had slyly attacked her, Indigo rushed at the sleeping Cobalt and slapped her face.
 
At once there was war. The other four Princesses, hearing the screams and cries of rage, came running into Cobalt's room, and as fast as they appeared, Trot threw pillows at them, so that presently all six were indulging in a free-for-all battle and snarling like tigers. The blue lamb came trotting into the room, and Trot leaned over and patted the pretty little animal, but as she did so, she became visible for an instant, each pat destroying the charm of the ring while the girl was in contact with a living creature. These flashes permitted some of the Princesses to see her, and at once they rushed toward her with furious cries. But the girl realized what had happened, and leaving the lamb, she stepped back into a corner and her frenzied enemies failed to find her. It was a little dangerous, though, remaining in a room where six girls were feeling all around for her, so she went away and left them to their vain search while she renewed her hunt for Cap'n Bill.
 
The sailorman did not seem to be in any of the rooms she entered, so she decided to visit the Boolooroo's own apartments. In the room where Rosalie's vision had shown them the Magic Umbrella lying under a cabinet, Trot attempted to find it, for she considered that next to rescuing Cap'n Bill this was the most important task to accomplish; but the umbrella had been taken away and was no longer beneath the cabinet. This was a severe disappointment to the child, but she reflected that the umbrella was surely someplace in the Blue city, so there was no need to despair.
 
Finally, she entered the King's own sleeping chamber and found the Boolooroo in bed and asleep, with a funny nightcap tied over his egg-shaped head. As Trot looked at him, she was surprised to see that he had one foot out of bed and that to his big toe was tied a cord that led out of the bedchamber into a small dressing room beyond. Trot slowly followed this cord and in the dressing room came upon Cap'n Bill, who was lying asleep upon a lounge and snoring with great vigor. His arms were tied to his body, and his body was tied fast to the lounge. The wooden leg stuck out into the room at an angle, and the shoe on his one foot had been removed so that the end of the cord could be fastened to the sailor's big toe.
 
This arrangement had been a clever thought of the Boolooroo. Fearing his important prisoner might escape before he was patched as Ghip-Ghisizzle had done, the cruel King of the Blues had kept Cap'n Bill in his private apartments and had tied his own big toe to the prisoner's big toe, so that if the sailor made any attempt to get away, he would pull on the cord, and that would arouse the Boolooroo.
 
Trot saw through this cunning scheme at once, so the first thing she did was to untie the cord from Cap'n Bill's big toe and retie it to the leg of the lounge. Then she unfastened her friend's hands and leaned over to give his leathery face a smacking kiss. Cap'n Bill sat up and rubbed his eyes. He looked around the room and rubbed his eyes again, seeing no one who could have kissed him. Then he discovered that his bonds had been removed, and he rubbed his eyes once more to make sure he was not dreaming. The little girl laughed softly.
 
"Trot!" exclaimed the sailor, recognizing her voice.
 
Then Trot came up and took his hand, the touch at once rendering her visible to him. "Dear me!" said the bewildered sailor. "However did you get here, mate, in the Boolooroo's own den? Is the Blue City captured?"
 
"Not yet," she replied, "but YOU are, Cap'n, and I've come to save you."
 
"All alone, Trot?"
 
"All alone, Cap'n Bill. But it's got to be done, jus' the same." And then she explained about the magic ring Rosalie had lent her, which rendered her invisible while she wore it—unless she touched some living creature. Cap'n Bill was much interested.
 
"I'm willing to be saved, mate," he said, "for the Boolooroo is set on patchin' me right after breakfas', which I hope the cook'll be late with."
 
"Who are you to be patched to?" she asked.
 
"A feller named Tiggle, who's in disgrace 'cause he mixed the royal necktie for me."
 
"That was nectar, not necktie," corrected Trot. "But you needn't be 'fraid of bein' patched with Tiggle, 'cause I've set him loose. By this time he's in hiding, where he can't be found."
 
"That's good," said Cap'n Bill, nodding approval, "but the blamed ol' Boolooroo's sure to find someone else. What's to be done, mate?"
 
Trot thought about it for a moment. Then she remembered how some unknown man had escaped from the palace the night before by means of the wall, which he had reached from the window of the very chamber in which she had slept. Cap'n Bill might easily do the same. And the r............
