They stumbled along behind her, half-dead for sleep, and she urged them on, though she was as tired and as discouraged as they were. She had never been in Canada but she kept painting wondrous word pictures of what it would be like. She managed to dispel their fear of pursuit, so that they would not become hysterical, panic-stricken. Then she had to bring some of the fear back, so that they would stay awake and keep walking though they drooped with sleep.
