And now--why am I writing you?

Heaven knows, unless it is that the persistent clicking of thatunfathomable enigma out there in the vast silences of the Saharahas so wrought upon my nerves that reason refuses longer to functionsanely.

I cannot hear it now, yet I know that far away to the south, allalone beneath the sands, it is still pounding out its vain, franticappeal.

It is maddening

It is your fault--I want you to release me from it.

Cable me at once, at my expense, that there was no basis of factfor your story, At the Earth's Core.
