It happened that the very next day she was sent on a message to one of the offices and that the gentleman to whom she gave the message, a dried-up gentleman with bright shining spectacles, asked her if she would like a penny to buy some lollipops. "No, thank you, sir," said Mary, curtseying. "I'd like to go upstairs and look at those picture books at the top of the house." Whereupon the dried-up gentleman mysteriously muttered, "Old stock! Old stock!" just like Uncle William yesterday. "Why, you may go there whenever you like, my little maid," he told her. "Fancy that!" exclaimed Mrs. Fawcus when she was informed of this by Mary. "Well, did you ever? I'm sure I never did. I never did know such an old-fashioned child in my life, Uncle William. Never! Fancy her asking such a thing of Mr. Bristowe." "It's old stock," said Mr. Fawcus. And Mary when she had been given leave by her uncle and aunt to avail herself of Mr. Bristowe's kind offer whispered "old stock" when she opened the door of that dusty attic, for she felt that it was an enchanted phrase like Open Sesame. The attic window looked down into the backyard of the basement, and Mary could not resist opening the window, for although she felt sure that she ought not to lean out of a window, inasmuch as she lived in a basement she had never actually been forbidden to lean out of windows. Yes, there were her flowers, such tiny specks of color, down below, and there was the dustbin looking more than ever like a knight in armor, and there was her thrush's cage. Hark! he was singing. She could hear his song above the thunder of the London streets. The attic window had a window-seat where Mary spent long lovely mornings in April reading those dusty picture books one after another, face to face with the clouds while the golden cross upon the dome of St. Paul's glittered in the sun. On the sill were the remains of a battered window-box still half full of earth. In this Mary sowed nasturtium seeds which grew miraculously, so that soon when Mary was in the yard she could look up and see the orange and yellow flowers waving in the wind against the dingy bricks of the warehouse. "Rapunzel, Rapunzel," she called. "Let down your golden hair." "What are you talking about?" Mrs. Fawcus exclaimed. "I'm being the witch," Mary told her. "Which what?" "The witch. The witch who climbed up to the tower by Rapunzel's golden hair." "Did anybody ever hear anything like it?" And when Mrs. Fawcus came out into the yard at Mary's invitation and looking up saw the nasturtiums, she was more exclamatory than ever. "Well, it give me quite a turn," she vowed to Uncle William. "The like of that child was never known." Nearly all the clerks in the office came up to look at Mary's nasturtiums; and Mr. Bristowe was so much delighted that he gave her a small red watering-can. "It's a wonder the sparrows don't peck them to pieces," said Mr. Fawcus, when Mary's triumph was being discussed in the basement.
