What puzzles you, my boy?
Several things. I cannot understand where all the stars are rolling to,
why they all keep together so cleverly in their motion, or why they are
moving at all.
Did you see any stars setting as well as rising?
Yes, father.
Well, as I want you to find out this subject yourself, I shall allow
you to stay up later this evening, to give you time to make a few more
observations. Now, follow your bright star a little further. Look at
that blue one overhead, and trace his journey. Have your eyes upon
Sirius, and the band of Orion.
