"Have you seen it, Barbara?"
"Of course I have."
"You never told me. It isn't fair to go discovering things on your own and not telling me. We must make a compact. To tell each other the very instant we see a thing. We might keep count and give points to which of us sees most. Mrs. Levitt ought to have been a hundred to your score."
"I'm afraid I can't score with Mrs. Levitt. You saw that, too."
"It'll be a game for gods, Barbara."
"But, Ralph, there might be things we couldn't tell each other. It mightn't be fair to him."
"Telling each other isn't like telling other people. Hang it all, if we're making a study of him we're making a study. Science is science. We've no right to suppress anything. At any moment one of us might see something absolutely vital."
"Whatever we do we musn't be unfair to him."
"But he's ours, isn't he? We can't be unfair to him. And we've got to be fair to each other. Think of the frightful advantage you might have over me. You're bound to see more things than I do."
"I might see more, but you'll understand more."
