"This statement I can not disprove, and therefore must admit under protest. Where there is so much that appears mysterious I may have overlooked some things, but I can scarcely accept that, in ignorance, I have passed conditions in my own organization so marked as this decrease in gravity which has so strikingly been called to my attention."

"You have, and to convince you I need only say that you have nearly ceased to breathe, and are unconscious of the fact."

I stopped short, in momentary alarm, and now that my mind was directed to the fact, I became aware that I did not desire to breathe, and that my chest had ceased to heave with the alternate inhalation and exhalation of former times. I closed my lips firmly, and for a long period there was no desire for breath, then a slight involuntary inhalation followed, and an exhalation, scarcely noticeable, succeeded by a great interval of inaction. I impulsively turned my face toward the passage we had trod; a feeling of alarm possessed me, an uncontrollable, inexpressible desire to flee from the mysterious earth-being beside me, to return to men, and be an earth-surface man again, and I started backward through the chamber we had passed.

The guide [seized] me by the hand, "Hold, hold," he cried; "where would you go, fickle mortal?"

"To the surface," I shouted; "to daylight again. Unhand me, unearthly creature, abnormal being, man or devil; have you not inveigled me far enough into occult realms that should be forever sealed from mankind? Have you not taken from me all that men love or cherish, and undone every tie of kith or kin? Have you not led me into paths that the imagination of the novelist dare not conjure, and into experiences that pen in human hand would not venture to describe as possible, until I now stand with my feet on the boundary line that borders vacancy, and utter loss of weight; with a body nearly lost as a material substance, verging into nothing, and lastly with breath practically extinguished, I say, and repeat, is it not time that I should hesitate and pause in my reckless career?"

"It is not time," he answered.

"When will that hour come?" I asked in desperation, and I trembled as he replied:

"When the three Great Lights are closed."
