The doctor returned his gaze with perfect equanimity. He looked at Van Emmon and Billie; they, too, seemed to think that the engineer had found a real flaw in Kinney's reasoning. The doctor dropped his eyes, and searched his mind thoroughly for the best words. He removed his bracelets while he was thinking; the others did the same. All four got to their feet and stretched, silently but thoroughly. Not until they were ready to quit the study did the doctor make reply.
"Smith, I don't need to remind you that it's the little things that count. It's too old a saying. In this case it happens to be the greatest truth we have found today.
"Smith"—speaking with the utmost care—"what we have just said about the bee's sting is all true; but only with regard to the bees on the earth. It is only on the earth, so far as we know positively, that the bee is averse to stinging, for fear of losing his sting.
"There is only one way to account for the soldier bee. Its sting has no barbs!"
"No barbs?"
"Why no? If the poison is virulent enough, the barbs wouldn't be necessary, would they? Friends, the Sanusian bee is the supreme creature on its planet; it is superior to all the other insects, all the birds, all the animals; and its supremacy is due solely and entirely to the fact that there are no barbs on its sting!"
VII
THE MISSING FACTOR
By the time the four once more got together in the doctor's study, each had had a chance to consider the Sanusian situation pretty thoroughly. All but Billie were convinced that the humans were deserving people, whose position was all the more regrettable because due, so far as could be seen, the insignificant little detail of the barbless sting.
Were these people doomed forever to live their lives for the sake of insects? Were they always to remain, primitive and uncultured, in ignorance of, the things that civilization is built upon, obeying the orders of creatures who were content to eat, reproduce, and die? For that is all that bees know!
