When the square suddenly seemed to begin to glow in an enchanted way and look wonderful in spite of its sooty trees and railings, Sara knew something was going on in the sky; and when it was at all possible to leave the kitchen without being missed or called back, she invariably stole away and crept up the flights of stairs, and, climbing on the old table, got her head and body as far out of the window as possible. When she had accomplished this, she always drew a long breath and looked all round her. It used to seem as if she had all the sky and the world to herself. No one else ever looked out of the other attics. Generally the skylights were closed; but even if they were propped open to admit air, no one seemed to come near them.
