“These are your knapsacks,” said Old Nancy, smiling. “You will find them useful on your journey. This is yours,” she said to Molly, “and this is yours,” to Jack. “Now if you will open them and take out what is inside, I will explain what they are meant for.” The children thanked her and eagerly unbuckled their satchels and felt inside. The contents of each were the same: a sealed envelope, a box of matches, and a little packet of square, brown things that looked like caramels. “Inside the envelopes are your Passes into the City. Give them up at the City Gates. Take care of them, without them they would not let you in. The matches in those two boxes are not quite ordinary matches—though they look like ordinary ones. I think they’ll help you over one or two difficulties. Use them carefully as there are not many matches in each box. Whatever you do don’t light them in the daytime, but light them when you are in the dark and want to see.” “Do we strike them just in the ordinary way?” asked Molly. “Just in the ordinary way,” said old Nancy. “And the little brown squares in the packets are for you to eat, should you be very hungry, and unable to obtain food. You will find them wonderfully refreshing—it is something I make specially.... And here,” she continued, turning to Jack, and holding something out to him, “is another shoe for you. I see you have only got one on.” “Why, so I have,” cried Jack, noticing for the first time that one of his slippers was missing. “Now wherever did I lose that, I wonder!” (Poor little slipper, it takes no part in these adventures, as it is left behind in the Impossible World. It is lying by the fence at the bottom of the children’s garden, you remember.) “I never noticed it before. Thanks awfully, though. This slipper fits splendidly. How did you know my size?” “Oh, I knew,” Old Nancy laughed, and would say no more. She helped the children buckle on their satchels, telling them that once they were inside the City they would learn what plans were being made for the search. “I wish I could give you some magic charm to defend you against the Pumpkin,” she said. “But that is impossible. The Black Leaf is the only thing that can harm him, and save us all. Be very careful, dear children.... Ah!” she broke off with a sharp exclamation. “What is it? What’s the matter?” cried Jack and Molly, as Old Nancy stood gazing at her left hand which she held out in front of her. “So that’s how it was done,” she cried. “Look! Look!” and she held her hand toward them. A dark grey mark stained the middle finger from base to tip. “What is it?” Molly repeated.
