"But course is more near to the truth," said Fred, "than star. Don't you see that Bishop Berkeley wrote before railways were invented, and before people could travel as they do nowadays? Emigrants, when they went out West, went with wagons, or on horseback, or on foot. They travelled by day and rested at night. Now—don't you see?—they made their course in the daytime, when they couldn't see the stars at all; and when the stars were out, they were asleep, unless the wolves or the Indians kept them awake. They were too tired to waste any time over a twinkling star of empire, but they knew all about the course.".
