“Oh yes, it’s tremendously hard work,” said Ian, recovering himself; “you have to detach it from the roof, you know, and it is wonderful the tenacity with which nails hold on sometimes; and then there’s the fitting of the new shingle to the—”

“Come, don’t talk nonsense,” said Cora; “you know that is not what kept you. You have been telling some secret to Elsie. What was it?”

Instead of answering, Ian turned with a twinkle in his eyes, and asked abruptly:

“By the way—when does Louis Lambert return?”

It was now Cora’s turn to flush.

“I don’t know,” she said, bending quickly over her work; “how should I know? But you have not answered my question.—Oh! look there!”

She pointed to the doorway, where a huge rat was seen seated, looking at them as if in solemn surprise at the trifling nature of their conversation.

Not sorry to have a reason for escaping, Ian uttered a laughing shout, threw his cap at the creature, missed, and rushed out of the room in chase of it. Of course he did not catch it; but, continuing his flight down-stairs, he jumped into the punt, pushed through the passage, and out at the front door. As he passed under the windows he looked up with a smile, and saw Cora shaking her little fist at him.

“You have not improved in your shooting,” she cried; “you missed the rat.”

“Never mind,” he replied, “Lambert will fetch his rifle and hunt for it; and, I say, Cora, ask Elsie to explain how shingles are put on. She knows all about it.”
