Now the little brown elf thought this a most unusual wish, but he told Tom he would grant it for one day, and instantly Tom felt a sudden gust of air and found himself entirely alone. Just then he heard the turnkey coming with his bread and water and he hurriedly wished himself invisible, and when the door was opened he walked right out of his cell between the big man’s bow legs! He chuckled in glee to himself when he saw the turnkey looking all about for him, not being able to find him anywhere, and then he set about finding his way to the street. On his way home Tom passed a lake that the frost had converted into a solid sheet of gleaming ice, where all the boys and girls were skating. He spied a pair of skates lying on the bank, and quick as a thought, he had them on his feet and had darted off across the ice. There were loud shouts of surprise from everyone, and he saw all the boys and girls looking after him in amazement. Of course, all _they_ could see was the skates, which they thought must have been bewitched to go skating off by themselves. A dozen boys set out in pursuit of them, and Tom quite enjoyed the sport of eluding them. Teddy, who was in the crowd, almost caught up with him, but, hearing a voice that seemed to come from the skates themselves, saying, “You _know_ you broke the window!” he became so frightened that he stumbled and fell, slithered over the thin ice around a “Danger” sign, broke through and plunged headlong into the cold water. [Illustration: _All They Could See Was the Skates_] Before the other boys and girls could reach him, Invisible Tom had pulled him out. When Teddy felt hands helping him out but could see no one, he cried aloud in fear, but Tom just chuckled to himself and glided off, quite satisfied with his first adventure. By this time he was tired of skating, so, leaving the skates where he had found them, he went merrily and invisibly on his way. A poor little homeless dog whose leg had been injured by a passing truck was limping painfully along ahead of Tom, and at last tumbled into a pathetic little heap, unable to drag himself further. A rough boy, whom Tom did not know, came by just at that moment and began tormenting the poor little animal. ’Twas then Tom thought he could have some fun by befriending the dog and playing a trick on the boy. So he dashed over, picked the dog up in his invisible arms, and carried him safely down the street. When he looked back and saw the boy standing with his mouth wide open in amazement at seeing a dog floating away in the air, he laughed aloud. This was indeed great fun! Tom went out of his way to pass the Dog Hospital, where he dropped his little charge carefully in through an open window just high enough from the ground for him to reach.
