Aunt Madge and Dr. Anderson were to come out two days later. There was so much to do in these two days, however, that the time flew quickly. Mary Lee did not neglect her duties but with the help of her friends she was able to get through early so that most of the day was free. The first picnic lunch had been so successful that they had unanimously planned for another. There were, however, so many other things to do that it was put off for the arrival of the newcomers.

Dr. Anderson brought his car and almost in the first moment of his arrival had made plans for a long ride, but Mary Lee reminded him of her plan to visit the Sanitarium.

"Well, Mary Lee," he agreed good humoredly. "Of course, it will be talking shop for me to take you youngsters through, but if that is what you wish, I will gladly do so."

"Suppose we take our ride later," suggested Bob, who felt more at liberty to suggest than the others because Aunt Madge was his aunt and Dr. Anderson would soon be his uncle. "We could stay out late and you could return to town in the morning."

Aunt Madge laughed. "It's not so easily planned as all that, but even then I think we can manage."

Dr. Anderson telephoned the hospital as soon as they reached the house. He obtained permission almost at once to go through with his party. His business with Mr. Quinn was transacted in half an hour and so it was still quite early in the morning when they reached the hospital. It was a large institution which made a specialty of certain kinds of cases, but it also had an emergency ward.

The doctor explained so thoroughly, yet so simply, to his listeners as they went through the operating rooms, etc., that they could not help having a good conception of the necessary treatment of the sick.

In the midst of an explanation he saw Mary Lee's attention centered on a nurse who was taking the temperature of a patient.

"Yes, Mary Lee, that is what you will be doing some day. You have made a splendid choice of profession. It will take many years—there is much you must learn. I know," he continued, jestingly, "folks will be glad to get sick just so that they can have Dr. Anderson treat them and Nurse Mary Lee take care of them."

"It isn't going to take as many years as you think," loyally replied Bob, taking up the cudgels, "for Mary Lee has already begun." And he told Aunt Madge and the doctor of Tom Marshall. To Bob, because he was a boy, the part that had to do with the silver mine in Mexico was important and so he dwelt upon it.

"Tom Marshall told Mary Lee that he has a partner who is an Indian and who is a whiter and squarer man than many white men," concluded the boy.

For one moment, Dr. Anderson wondered at this last remark the boy had made.

"An Indian for a partner, eh?" he remarked. Then he laughed at the foolishness of his thought. Of course, there could be no connection between Jim Lee, the Indian who had been a servant to Mary Lee's mother out West, and this Indian Bob had spoken about.

"You didn't say what the Indian's name was, did you?" he asked.

Mary Lee answered, "No, I never thought to ask."

"Well, let's be on," Dr. Anderson said, casting away all thoughts and conjectures as to the possibilities along this line. "That was a good home remedy you applied to the man, Mary Lee," he continued, changing the subject by referring to the mustard the girl had applied for the sunstroke.

It was long past the time for lunch when they left the hospital. Probably Mary Lee learned more than any one of the others from this visit, for everything had been of such vital interest to her. She remembered much of what the doctor had told them.

Immediately after the late lunch which Mrs. Quinn had prepared for them they started out. The girls noticed with astonishment that Aunt Madge was driving the auto.

"Oh, yes," she replied in answer to their exclamations, "Dr. Anderson taught me. I find it easy to drive here in comparison with the city. It isn't hard," she added with all the certainty of one who has already learned.

"Tell you what, Madge, dear, I'll teach one or two of these youngsters. Shall I?"

"What a fine idea," Aunt Madge replied, giving up her seat.

Neither Letty nor Ruth would attempt it, however. Bob already knew, but Mary Lee welcomed the opportunity of learning.

Dr. Anderson found her an apt pupil and after the first hour he let her drive the car alone, taking the precaution, of course, of keeping his foot on the emergency clutch. At the end of another half hour, the doctor replaced her and put on extra speed.

The car whizzed along now. At four o'clock he found a suitable place and stopped. The whole party got out and made themselves comfortable.

Aunt Madge broke the news of the girls' appointment as bridesmaids.

"Too bad, Bob, you are not quite old enough, or I would make you my best man," said the doctor.

"At any rate, I'll be there," the boy replied. But the girls were not listening. They were eagerly discussing their plans with Aunt Madge. The doctor and Bob looked at them with much amusement and then walked down past the car and on.

It was soon time to return, however. Long after seven the party reached the house. Neither Aunt Madge nor Dr. Anderson could stay over and they began their long trip home.

The girls and Bob were a tired, happy lot and retired almost at once.
