Helen Chase Adams proved to be a pains-taking and extremely slow sewer. Besides, she insisted on taking time off to learn her history and geometry, instead of "risking" them as Betty did and urged her to do. The result was that Betty had to refuse Mary Brooks's invitation to "come down to the gym and dance the wax into that blooming floor" the next afternoon, and was tired and cross by the time she had done Helen's hair low, hooked her into the transformed dress, and finished her own toilette. She had never thought to ask the name of Helen's junior, and was surprised and pleased when Dorothy King appeared at their door. Dorothy's amazement was undisguised.
