Jimmy secured the only physician in the neighborhood, loaded the doctor and the necessary supplies in his plane, and was soon back on the island. The medical assistance came in time. The doctor was able to give immediate treatments and to leave directions for further care. As for Jimmy himself, nothing was too good for him on the island. The inhabitants would have given him almost anything he asked for, so grateful were they for his efforts in their behalf. But Jimmy wanted nothing. He was more than repaid by their gratitude and their friendship. It was with real regret that Jimmy said goodbye to these new-found friends. He was amazed to see how rapidly a mutual feeling of regard had sprung up between these people and himself in such a short time. He understood, of course, that this was because of the unusual conditions under which they had come to know one another. When the time for departure came, he shook hands with them all, promised to come back to the island some time, and then ferried his doctor back to Smithville. And now he went winging his way home across the great Empire State, to his old quarters at the Long Island flying field. Weeks later Jimmy learned that the rescue efforts he had set in motion had been wholly successful. Every one of the seven sufferers had recovered. But more astonishing than that was the news that for a week after Jimmy’s departure, the sick islanders had daily treatment from the Smithville physician. The rum runner from Canada had flown the physician back and forth every day, as long as it was necessary, in a new plane, and had concluded the matter by paying the doctor handsomely for his services. Jimmy mused over this for quite a while. “It just shows,” he concluded, “that the poet was right when he said there is so much bad in the best of us and so much good in the worst of us that we ought to be mighty careful what we say about anybody.” CHAPTER XV Jimmy Joins the Caterpillar Club
