After a while she remembered that she still held the pieces of mushroom in her hands, and she set to work very carefully, nibbling first at one and then at the other, and growing sometimes taller, and sometimes shorter, until she had succeeded in bringing herself down to her usual height.
It was so long since she had been anything near the right size, that it felt quite strange at first; but she got used to it in a few minutes, and began talking to herself, as usual, “Come, there’s half my plan done now! How puzzling all these changes are! I’m never sure what I’m going to be, from one minute to another! However, I’ve got back to my right size: the next thing is, to get into that beautiful garden—how is that to be done, I wonder?” As she said this, she came suddenly upon an open place, with a little house in it about four feet high. “Whoever lives there,” thought Alice, “it’ll never do to come upon them this size: why, I should frighten them out of their wits!” So she began nibbling at the right-hand bit again, and did not venture to go near the house till she had brought herself down to nine inches high.
