By tea-time it wasn't Susan that was up, but her temperature. Throughout the afternoon the family had dropped into her room at intervals to commiserate with her, and the cause of all the trouble came down and settled with her under the eiderdown when Aunt Lucy wasn't looking. Susan was very glad to see them all, but she couldn't help wishing that she was in better trim, as she put it, for vistors. Really, she felt very peculiar indeed, and in spite of two hot-water bottles, four blankets, an eiderdown and Chang, she just couldn't get warm.
