"Possibly not ... not for you, Macdonald. If you use authority the bairns will hardly question it. But I don't see that you have the right to be an autocrat in this affair."

"It is my duty to protect the children," he said with dignity.

"Protect yourself, you mean!" I cried; "you have just confessed that your one aim is to get rid of awkward questions."

"But what can I do?" he stammered.

"Do! Do nothing, just as I did. Let the creatures breed as much as they darned well please; that's what they are there for. You can't very well make sex an object lesson; the logical thing to do is to give a lesson on pollination of plants and then go on to fertilisation of the bird's egg, but if you do that you'll get the sack at once. But there's quite enough of prudery in the world already without your turning a rabbit-hutch into a sultanless harem."

"There are things that children shouldn't know," he said with a touch of aggression.

"And there are things that grown-ups should know and don't," I said. "They ought to know that the sex conspiracy of silence is idiotic and criminal."

"Anyway," he said sullenly, "I'll tell them to-morrow that there are too many in the house and that I mean to get rid of a few."

"All right," I said resignedly, "you can lie to them if you want to." Then I added: "Although, mind you, Macdonald, I feel like telling the bairns the real reason for your action."

He looked startled.
