"Perhaps a cave might not be so very pleasant," rejoined Lubin. "But I wish that some good-natured fairy could furnish these cottages of ours with a stroke of her wand, and save us all this terrible trouble."

"It would not be so good for us, I daresay," said Nelly, stumbling again at nine times six.

"And why not?" inquired her brother.

"Why," replied Nelly, as she rubbed her bruised ankle, "I think that the trouble and pain serve to exercise our patience and perseverance, and to make us more fit to meet the trials which are sure to come when we are older.

"I'm sure that we can have no pleasure from this Multiplication stair."

"Hurrah! hurrah!" shouted Lubin, not long after, as he stood panting on the topmost step.

"Oh, what a charming view!" exclaimed Nelly. "I'm so glad that we persevered!"
