Jack rubbed his eyes in astonishment, and gazed wonderingly at the brown-paper package. What could it be? Certainly not his fur coat. A limousine car and the lady of the wheezy hand-organ did not seem to go together. In an instant, consumed with curiosity, he tore off the brown-paper covering, and found within a white pasteboard box, oblong in shape, and tied up with blue ribbon. Attached to the middle was a note, which, on being opened, revealed the following message to Jack's staring eyes: THE UNITED STATES FAIRY COMPANY 8976 WALL STREET NEW YORK, _December 12, 1910_. DEAR JACK,--I return your cloak herewith with many thanks for your kindness to Yours gratefully, TITANIA J. GODMOTHER, President The United States Fairy Co. "Well, I'll be blowed!" ejaculated the lad as he read. "The old lady a fairy? I don't know about this--it has a phony look to me!" As he spoke he cut the blue ribbon with his penknife and opened the box. The mystery, instead of being solved, now became all the deeper, for as far as Jack's eye was able to see the box was empty. The janitor grinned unsympathetically. "Quare toime for an April-fool joke!" he said, as he left the room. For a few moments Jack was as silent as the Sphinx, and then, with a sudden surge of wrath that any one should play such a trick upon him, he gave the box a kick that sent it flying across the room. It landed on a chair, the cover fell off, and then, mystery of mysteries, three-quarters of the chair disappeared wholly from sight. Again Jack rubbed his eyes in amazement, and slowly, like a trapper passing along a forest trail, he crept over to where the chair stood and put out his hand to feel for its missing parts. In a moment he was reassured as to their existence, for he could feel the outlines of the missing sections, but something apparently lay across them. It was a soft, silky material, tangible enough, but absolutely invisible. It felt like a cloak, and as Jack passed his hands along its folds he found that it had sleeves, buttons, buttonholes, and a hood at the back of its collar, not to mention several capacious pockets within. "Huh!" he ejaculated. "It feels like an invisible ulster. I wonder--" An idea flashed across his mind, acting upon which he seized the cloak, and rushed into his bedroom, where, standing before the mirror on his bureau, he put it on, buttoning it all the way up to his neck. This done, he glanced at himself in the glass. _Only his head, which had remained uncovered, was reflected there!_ "Well of all--" he began, astounded at the vision before him, or rather the lack of it. Hastily he pulled the hood over his head, and immediately, as far as the eye could see, he completely vanished. And then Jack knew what had happened. The fairy godmother had given him one of the choicest possessions of her kingdom--the famous invisible cloak!
