Fifteen years, ago Thomas Irving had gone to California and five years later he had died there. Mary Isabel, who had idolized her brother, almost grieved herself to death at the time.

Finally she opened the letter with ice-cold fingers. It had been written soon after Tom reached California. The first two pages were filled with descriptions of the country and his "job."

On the third Tom began abruptly:

Look here, Mary Isabel, you are not to let Louisa boss you about as she was doing when I was at home. I was going to speak to you about it before I came away, but I forgot. Lou is a fine girl, but she is too domineering, and the more you give in to her the worse it makes her. You're far too easy-going for your own welfare, Mary Isabel, and for your own sake I Wish you had more spunk. Don't let Louisa live your life for you; just you live it yourself. Never mind if there is some friction at first; Lou will give in when she finds she has to, and you'll both be the better for it, I want you to be real happy, Mary Isabel, but you won't be if you don't assert your independence. Giving in the way you do is bad for both you and Louisa. It will make her a tyrant and you a poor-spirited creature of no account in the world. Just brace up and stand firm.

When she had read the letter through Mary Isabel took it to her own room and locked it in her bureau drawer. Then she sat by her window, looking out into a sea-sunset, and thought it over. Coming in the strange way it had, the letter seemed a message from the dead, and Mary Isabel had a superstitious conviction that she must obey it. She had always had a great respect for Tom's opinion. He was right—oh, she felt that he was right. What a pity she had not received the letter long ago, before the shackles of habit had become so firmly riveted. But it was not too late yet. She would rebel at last and—how had Tom phrased it—oh, yes, assert her independence. She owed it to Tom; It had been his wish—and he was dead—and she would do her best to fulfil it.

"I shan't get a bonnet," thought Mary Isabel determinedly. "Tom wouldn't have liked me in a bonnet. From this out I'm just going to do exactly as Tom would have liked me to do, no matter how afraid I am of Louisa. And, oh, I am horribly afraid of her."

Mary Isabel was every whit as much afraid the next morning after breakfast but she did not look it, by reason of the flush on her cheeks and the glint in her brown eyes. She had put Tom's letter in the bosom of her dress and she pressed her fingertips on it that the crackle might give her courage.

"Louisa," she said firmly, "I am going to town with you."

"Nonsense," said Louisa shortly.

"You may call it nonsense if you like, but I am going," said Mary Isabel unquailingly. "I have made up my mind on that point, Louisa, and nothing you can say will alter it."
