His sister looked anxiously at him.
"Well, Bob, you are looking a little pale, but so is everybody else; and no wonder, with this heat. But I have not been noticing you, particularly. What do you feel, Bob?"
"I think Bob feels as if he wants a holiday," Captain O'Halloran put in.
"Well, then, we must tell the professor that we don't want him to come, for a bit. Of course, Teddy Burke has given up coming, already.
"But if you have a holiday, Bob, what will you do with yourself?"
"I don't think I shall get any better here, Carrie. I think I want change of air."
"Nonsense, Bob! You can't be as bad as all that; and you never said anything about it, before.
"If he is not well, you must ask Teddy Burke to come up to see him, Gerald. Besides, how can he have change of air? The only place he could go to would be Tetuan, and it would be hotter there than it is here."
"I think, Carrie," Captain O'Halloran said, "I can prescribe for him without calling Teddy Burke in. I fancy the very thing that would get Bob set up would be a sea voyage."
"A sea voyage!" his wife repeated. "Do you mean that he should go back to England? I don't see anything serious the matter with him. Surely there cannot be anything serious enough for that."
