I stared, trying to force every atom of vision from my eyes.  For a long time I thought they must every moment disappear and resolve themselves into the movements of the branches and prove to be an optical illusion.  I searched everywhere for a proof of reality, when all the while I understood quite well that the standard of reality had changed.  For the longer I looked the more certain I became that these figures were real and living, though perhaps not according to the standards that the camera and the biologist would insist upon.

Far from feeling fear, I was possessed with a sense of awe and wonder such as I have never known.  I seemed to be gazing at the personified elemental forces of this haunted and primeval region.  Our intrusion had stirred the powers of the place into activity.  It was we who were the cause of the disturbance, and my brain filled to bursting with stories and legends of the spirits and deities of places that have been acknowledged and worshiped by men in all ages of the world’s history.  But, before I could arrive at any possible explanation, something impelled me to go farther out, and I crept forward on to the sand and stood upright.  I felt the ground still warm under my bare feet; the wind tore at my hair and face; and the sound of the river burst upon my ears with a sudden roar.  These things, I knew, were real, and proved that my senses were acting normally.  Yet the figures still rose from earth to heaven, silent, majestically, in a great spiral of grace and strength that overwhelmed me at length with a genuine deep emotion of worship.  I felt that I must fall down and worship—­absolutely worship.

Perhaps in another minute I might have done so, when a gust of wind swept against me with such force that it blew me sideways, and I nearly stumbled and fell.  It seemed to shake the dream violently out of me.  At least it gave me another point of view somehow.  The figures still remained, still ascended into heaven from the heart of the night, but my reason at last began to assert itself.  It must be a subjective experience, I argued—­none the less real for that, but still subjective.  The moonlight and the branches combined to work out these pictures upon the mirror of my imagination, and for some reason I projected them outwards and made them appear objective.  I knew this must be the case, of course.  I was the subject of a vivid and interesting hallucination.  I took courage, and began to move forward across the open patches of sand.  By Jove, though, was it all hallucination?  Was it merely subjective?  Did not my reason argue in the old futile way from the little standard of the known?

I only know that great column of figures ascended darkly into the sky for what seemed a very long period of time, and with a very complete measure of reality as most men are accustomed to gauge reality.  Then suddenly they were gone!
