"If he hadn't picked up this unlucky illness——"

"Well—I don't know," said the doctor. "I'm inclined to think you may yet consider it a blessing in disguise. You might have gone on pouring tonics and patent messes into him, and hoping he'd improve. You can't do it now. It's up to you and Aileen to give him every chance, if you want a strong son instead of a weakling."

"That's final?" Macleod asked.

"That's my considered opinion. I know your difficulties, old man. But I know you don't value anything in the world beyond Garth. Take him to the country; let him live out of doors, and run as wild as a rabbit; give him unlimited fresh milk—not the stuff you buy out of a can—country food, and pure air: let him wear old clothes all the time and sleep out of doors—and in a year I'd stake my professional reputation you won't know him. Keep him in a Melbourne suburb, and I won't be answerable for the consequences."

"That's pretty straight, anyhow," said Macleod.

"I mean it to be straight. I haven't known you since you were at school to mince matters with you now. And I'm fond of the kid: I want to see him grow into a decent man, with all the best that is in him given a fair chance."

"We've tried to do that," Macleod said. He looked round the glowing garden. "It's such a jolly home, and he does love it."

"It's one of the jolliest little homes I've ever seen, and it's going to hurt both of you badly to leave it," the doctor rejoined. "The trouble is, it is too jolly. You have made yourself a little Paradise inside the tallest paling fence you could build, and you've shut out all that lies outside that fence—miles on miles of teeming streets, packed and jammed with people. You're in the midst of grass and roses and things, with a sprinkler going on your tulips, or whatever those rainbow affairs are—and you don't think about the street outside, dry and baking, with a hot wind swirling the germ-laden dust about—blowing it probably upon the meat and fruit and milk you'll buy to-morrow. The air comes to you over thousands of houses, clean and dirty, and thousands of people breathe it. You've got to get where there's no second-hand air."

"Great Scott!" ejaculated Macleod. "Will you tell me how any children manage to live at all?"

"It's a special dispensation of Providence that most youngsters don't die from germs," said the doctor, laughing. "I'm aware that the infantile population of Melbourne is pretty healthy, but it's always a mystery to me how children in any big city survive their surroundings. After all, Melbourne's cleaner than most places. However, there is only one among its hordes of kids that is interesting you and me at the moment, and that's Garth. You've got to get him out of it, Tom."
