then effie took out the knife harry had given her on her birthday. it had cost only sixpence to begin with, and she had had it a month, and it never could sharpen anything but slate-pencils; but somehow she managed to make that knife cut her sash in front, and crept out of it, leaving the dragon with only a green silk bow in one of his claws. that knife would never have cut harry's jacket-tail off, though, and when effie had tried for some time she saw that this was so and gave it up. but with her help harry managed to wriggle quietly out of his sleeves, so that the dragon had only an eton jacket in his other claw. then the children crept on tiptoe to a crack in the rocks and got in. it was much too narrow for the dragon to get in also, so they stayed in there and waited to make faces at the dragon when he felt rested enough to sit up and begin to think about eating them. he was very angry, indeed, when they made faces at him, and blew out fire and smoke at them, but they ran farther into the cave so that he could not reach them, and when he was tired of blowing he went away.
