'I should say not.'

'You can well imagine then, that the earth has not the least idea of the way in which it is utilized by the human race. It is quite unaware of this fungus growth of vegetation and evolution of tiny animalcules which has collected upon it during its travels round the sun as barnacles gather upon the ancient vessel. That is the present state of affairs, and that is what I propose to alter.'

I stared in amazement. 'You propose to alter it?'

'I propose to let the earth know that there is at least one person, George Edward Challenger, who calls for attention – who, indeed, insists upon attention. It is certainly the first intimation it has ever had of the sort.'

'And how, sir, will you do this?'

'Ah, there we get down to business. You have touched the spot. I will again call your attention to this interesting little creature which I hold in my hand. It is all nerves and sensibility beneath that protective crust. Is it not evident that if a parasitic animalcule desired to call its attention it would sink a hole in its shell and so stimulate its sensory apparatus?'

'Certainly.'

'Or, again, we will take the case of the homely flea or a mosquito which explores the surface of the human body. We may be unaware of its presence. But presently, when it sinks its proboscis through the skin, which is our crust, we are disagreeably reminded that we are not altogether alone. My plans now will no doubt begin to dawn upon you. Light breaks in the darkness.'

'Good heavens! You propose to sink a shaft through the earth's crust?'

He closed his eyes with ineffable complacency.

'You see before you,' he said, 'the first who will ever pierce that horny hide. I may even put it in the present tense and say who has pierced it.'

'You have done it!'
