THE ELDERLY GENTLEMAN. When you say that you weed them out, you send a cold shiver down my spine. I hope you don't mean that you--that you--that you assist Nature in any way? ZOO. Why not? Have you not heard the saying of the Chinese sage Dee Ning, that a good garden needs weeding? But it is not necessary for us to interfere. We are naturally rather particular as to the conditions on which we consent to live. One does not mind the accidental loss of an arm or a leg or an eye: after all, no one with two legs is unhappy because he has not three; so why should a man with one be unhappy because he has not two? But infirmities of mind and temper are quite another matter. If one of us has no self-control, or is too weak to bear the strain of our truthful life without wincing, or is tormented by depraved appetites and superstitions, or is unable to keep free from pain and depression, he naturally becomes discouraged, and refuses to live. THE ELDERLY GENTLEMAN. Good Lord! Cuts his throat, do you mean? ZOO. No: why should he cut his throat? He simply dies. He wants to. He is out of countenance, as we call it. THE ELDERLY GENTLEMAN. Well!!! But suppose he is depraved enough not to want to die, and to settle the difficulty by killing all the rest of you? ZOO. Oh, he is one of the thoroughly degenerate shortlivers whom we occasionally produce. He emigrates. THE ELDERLY GENTLEMAN. And what becomes of him then? ZOO.

You astonish me; and yet I must admit that what you tell me accounts for a great deal of the little I know of the private life of our great men. We must be very convenient to you as a dumping place for your failures. ZOO. I admit that. THE ELDERLY GENTLEMAN. Good. Then if you carry out your plan of colonization, and leave no shortlived countries in the world, what will you do with your undesirables? ZOO. Kill them. Our tertiaries are not at all squeamish about killing. THE ELDERLY GENTLEMAN. Gracious Powers! ZOO [_glancing up at the sun_] Come. It is just sixteen o'clock; and you have to join your party at half-past in the temple in Galway. THE ELDERLY GENTLEMAN [_rising_] Galway! Shall I at last be able to boast of having seen that magnificent city? ZOO. You will be disappointed: we have no cities. There is a temple of the oracle: that is all. THE ELDERLY GENTLEMAN. Alas! and I came here to fulfil two long-cherished dreams. One was to see Galway. It has been said, 'See Galway and die.' The other was to contemplate the ruins of London. ZOO. Ruins! We do not tolerate ruins. Was London a place of any importance? THE ELDERLY GENTLEMAN [_amazed_] What! London! It was the mightiest city of antiquity.
