"You are cross to-night, Erskine. I don't see why I should. I thought 'Our' meant mine as much as hers. Why shouldn't she order one if she wanted it?"

He laughed, as though he was expected to understand that she was talking nonsense, but he spoke with an undertone of decision.

"Oh if it comes to that, the carriage as well as the horses are undoubtedly my mother's, but she and I have never drawn any hard and fast lines about 'mine' and 'thine'; I have always found her too willing to give up her convenience for mine. For that reason, perhaps, I have been careful to plan systematically for her, and to anticipate and overrule her personal sacrifices as much as possible, and I know that you will delight to join me in it. I am afraid that she was much inconvenienced to-day; still, that cannot be why she did not see any of her friends. What reason did she give, dear, for not coming down?"

Irene pouted in earnest this time.

"Really, Erskine, you are strangely obtuse! I have explained at least three times that mother spent the afternoon in her room, and that I gave orders that she should not be disturbed. I thought I should be commended for it instead of blamed."

"I haven't had a thought of blaming you, Irene, but I am a trifle anxious about my mother, and what you say only increases the anxiety. She has never been given to sleeping much in the daytime."

"Oh what nonsense! as though you knew what she did all day, while you are in town! Of course she sleeps; old people always do."

"My mother isn't old, Irene."
