It must be high up out of the reach of Pussy Cat, and big enough for Mrs. Mouse and her four babies.
What was that in the corner?
It was like a box, only very, very tall.
Mr. Mouse certainly did not know what it was, but I will tell you.
It was Boy Blue's grandfather's clock.
It had stood in that corner a long, long time, but Mr. Mouse had never seen it before.
"I think I could make a good nest on top of that box," he thought.
"Pussy Cat could not get up there, I know."
So Mr. Mouse began to run up the clock.
He heard it ticking very loudly.
