Tiny Desmond nodded gravely. He was not deceived by the kindly doctor's words. What he imagined was wrong with him for some time past—he had tried over and over again to treat it lightly—was no illusion. It was lung trouble.

"I ran over young Desmond this morning, Dr. Narfield," reported Dr. Anderson. "It's no use mincing matters, although I tried, ineffectually, I fear, to bluff the lad. One lung is badly affected; the other shows signs of pulmonary weakness. The best thing to be done is to send that youngster abroad—to a warm, dry climate. It will mean you losing a promising pupil, but that's an assured thing in any case. If he does go abroad there's a thundering good chance that he will make a complete recovery. If he doesn't—well——"

Dr. Anderson turned his thumbs down. There was no mistaking the significance of the act.

"I'll write to his parents at once," declared the Head. "I don't suppose for one moment they have noticed Desmond's condition. Parents rarely do; they trust implicitly to the school physician. Fortunately, Anderson, we've found out in time, I trust. By the bye, it might be a dispensation of Providence; how would East Africa suit him?"

"Quite all right in the uplands of the interior," replied Dr. Anderson. "The coast and the forest regions—no. Why do you ask?"

"Because not half an hour ago I received a letter from my brother Herbert," explained the Head. "You know he left there to take up an official appointment in Ceylon. His papers were cancelled for some reason, and instead he was given a post as mining engineer at Kilembonga, which is, I believe, about a hundred miles north-west of Tabora. He asks if I know of a couple of Stockmere boys about to leave school who would be willing to act as his assistants. Curiously enough, he mentioned Desmond and Sinclair."

"The very thing!" ejaculated Dr. Anderson. "You were telling me about young Sinclair—a hard case. I feel sorry for that lad."

The outcome of the conversation resulted in Colin Sinclair and Tiny Desmond being called to the Head's study. Briefly Dr. Narfield outlined his brother's request.

"It is a healthy life," he continued, "and there are excellent prospects of qualifying for a well-paid profession. If you two fellows would like to go, I will write to your respective parents, and if they are agreeable there's no reason why you shouldn't be in what was recently German East Africa in less than a couple of months. But I suppose you want time to consider matters?"
