My father bequeathed me a competency; some remoter ancestors lust to roam. I have combined the two and invested them carefully and without extravagance. I became interested in your story, At the Earth’s Core, not so much because of the probability of the tale as of a great and abiding wonder that people should be paid real money for writing such impossible trash. You will pardon my candor, but it is necessary that you understand my mental attitude toward this particular story—that you may credit that which follows.
