"Mark, the boy's heart cannot be in the wrong place while he is so fond of little children."
"If she grows up, doctor, and don't go to join her poor dear mother up there, I don't know that I'd wish her a better husband than your boy."
"It would be a poor enough match for her."
"Tut! She'll have the money, and he the brains. Doctor, that boy'll be a credit to you; he'll make a noise in the world, or I know nothing. And if his fancy holds seven years hence, and he wants still to turn traveller, let him. If he's minded to go round the world, I'll back him to go, somehow, or I'll eat my head, Ned Thurnall!"
So Tom carried Mary about all the morning, and next day went to Paris, and soon became the best pistol shot and billiard-player in the Quartier Latin. Then he went to St. Mumpsimus's Hospital in London, and became the best boxer therein, and captain of the eight-oar, besides winning prizes and certificates without end, and becoming in time the most popular house-surgeon in the hospital; but nothing could keep him permanently at home. Settle down in a country practice he would not. Cost his father a farthing he would not. So he started forth into the wide world with nothing but his wits and his science, an anatomical professor to a new college in some South American republic. Unfortunately, when he got there, he found that the annual revolution had just taken place, and that the party who had founded the college had all been shot. Whereat he whistled, and started off again, no man knew whither.
"Having got round half the world, daddy," he wrote home, "it's hard if I don't get round the other half."
With which he vanished into infinite space, and was only heard of by occasional letters dated from the Rocky Mountains, the Spanish West Indies, Otaheite, Singapore, the Falkland Islands, and all manner of unexpected places, sending home valuable notes, zoological and botanical.
At last when full four years were passed and gone since Tom started for South America, he descended from the box of the day-mail at Whitbury, with a serene and healthful countenance, shouldered his carpet-bag, and started for his father's house.
He walked in, and hung up his hat in the hall, just as if he had come in from a walk. Not finding the old man, he went into Mark Armsworth's, frightening out of her wits a pale, ugly girl of seventeen, whom he discovered to be his old playfellow, Mary. However, she soon recovered her equanimity, and longed to throw her arms round his neck as of old, and was only restrained by the thought that she was grown a great girl now. She called her father, and all the household, and after a while the old doctor came home, and the fatted calf was killed, and all made merry over the return of this altogether unrepentant prodigal son.
Tom Thurnall stayed a month at home, and then went to America, whence he wrote home in about six months. Then came a long silence, and then a letter from California; and then letters more regularly from Australia. Sickened with California life, he had crossed the Pacific once more, and was hard at work in the diggings, doctoring and gold-finding by turns.
