Then if art can produce such effects upon what we call an ethereal substance--if the waves of air can be compelled to carry their message only in the directions in which it is taught to go--what influence would such power have on more spiritual media? In other worlds, where it is not necessary for thoughts to express themselves in words, but where some more subtle power than that of air conveys ideas from one being to another, it is possible that an inquiring being might place himself at some central point where he might gather in all the information that is afloat in such a spiritual existence. Full of these thoughts, and my head, perhaps, a little bewildered by them, I passed unobserved into the orchestra, and ensconced myself in a little niche under the music-desk of the leader. I was surprised to find myself in a little cavity, from which there were loop-holes of observation into every part of the house, while there was a front view of the stage when the curtain should be raised. Seduced by the comfort of this little nook, and my speculations not being of the liveliest nature, it is not to be wondered at that I fell into a gentle sleep. I was aroused presently by the baton of the leader, struck with some force upon the desk over my head. I was aware, at the same time, of a whispering all around my ears, and an incessant noise, like that of aspen leaves in a summer breeze, which, in spite of its softness and delicacy, overpowered the sound of the loud orchestra. When I was able to recover myself, I began to find that I had indeed placed myself in the centre of the house; not in the centre of sound, but, if I may so express myself, of sensation. I was not listening to the conversations, but suddenly found myself the confidant of the thoughts of all the occupants of this well-filled house. I was lost in the multiplicity of ideas that were poured in upon me, and endeavored to concentrate myself upon one series of thoughts. I looked through my loop-holes, and presently selected one group towards which I might direct the opera-glass of my mental observation. There sat the five Misses Seymour. We had always distinguished them as the tall one, the light-haired one, the one who painted in oils, the one who had been south, and the little one whom nobody knew anything about. This individuality had been our only guide after having engaged Miss Seymour for a dance, and this was sufficient. The one who painted in oils always refused to dance; the one who had been south spoke with an accent, and said "_chick'n_" and "_fush_," if the conversation turned upon the bill of fare; and the others were distinguished by their personal appearance.
