id the doctor,
testing the real extent of her solicitude.

"I didn't think of that," answered Mrs. Preston, hastily. "On the
whole, you needn't write, then. It might communicate the disease to
Godfrey."

"She finds Godfrey very useful," the doctor thought.

"I will bear my anxiety as I can," she continued. "Have you thought of
anyone for a nurse?"

"I have thought of Mrs. Burke."

"She is poor, and will come if you offer her a good price. Try to get
her."

"I think she will come. I must go at once, for your husband needs
immediate attention."

"Get her to come at once, Dr. Townley! Oh, do! My husband may want
something, and I can't go into the room. My duty to my dear, only son
will not permit me. I hope Mr. Preston understands my motives in going
away?"

"I presume he does," said the doctor, rather equivocally.

"Tell him how great a sacrifice it is for me to leave his bedside. It
is a terrible trial for me, but my duty to my son makes it

The doctor bowed.

He drove at once to the humble dwelling of Mrs. Burke.

His errand was briefly explained.

"Can you come?" he asked. "I am authorized to offer you ten dollars a

"I would come in a minute, doctor, but what shall I do with Mary?"

"She shall stay at my house. I will gladly take charge of her."

"You are very kind, doctor. I wouldn't want to expose her, but I don't
mind myself. I don't think I am in danger, for I've had the smallpox

"Can you be ready in five minutes? Tell Mary to pack up her things,
and go to my house at once. We'll take good care of her."

In less than an hour Mrs. Burke was installed at the bedside of the
sick man as his nurse. As she entered the house, Mrs. Preston left it,
bound for the railway depot.

"I'm so glad you're here," she said, greeting the widow Burke with
unwonted cordiality. "I am sure you will take the best care of my
husband. I have told the doctor to pay you whatever you ask."

"I'll do my best, Mrs. Preston, but not for the money," answered Mrs.
Burke. "Your husband shall get well, if good care can cure him."

"I've no doubt of it; but the carriage is here, and I must go. Tell my
husband how sorry I am to leave him."

So Mrs. Preston went away, leaving a stranger to fulfill her own
duties at the bedside of her husband.

Thus it happened that, when Andy came home, he found his mother
already gone, and his sister on the point of starting fo
