"How many miles do you suppose he walks, Nursey?" asked Susy.
"I don't know. I wish I knew. And I wish I knew how many miles my hand travels in a week."
"Your hand! Why, just as many as your feet," said Susy.
"No such thing. See here now, look at me while I sew. Don't you see how my hand goes back and forth with every stitch? And when I make beds, and sweep and dust, and wash you children and dress you, and brush your hair, and pick up your toys—dear me! it's a wonder they're not used up, long ago!"
Susy laughed, and felt quite interested.
"Who told you any thing about that?" she asked.
"Nobody," said nurse. "Don't you suppose I ever have any thoughts of my own? However, I did see something in the paper about how far a printer's hand could travel in one day, and that set me to thinking about mine."
When Susy went to her mamma she told her what she and nurse had been talking about.
"I suspect your eyes are the greatest travellers you know much about," said her mamma. "Think how far they can go; and how many times they move from one end of the page to the other, when you read."
"I wish I knew how far," said Susy. "If Charlie ever comes here I mean to ask him to measure one of my books. He has got such a nice little carpenter's rule to measure with!"
