I pondered over these words, and a vague light, an undefined, inexpressible something that I could not put into words broke into my mind; I inferred that we were destined to meet with persons, or existences, possessed of new senses, of a mind development that man had not reached, and I was on the point of questioning my pilot when the motion of the boat was suspended, land appeared ahead, we drew up to it, and disembarked. Lifting the boat from the water my guide placed it on land at the edge of the motionless lake, and we resumed our journey. The scenery seemed but little changed from that of the latter part of our previous line of travel down the inclined plane of the opposite side of the lake that we had crossed. The direction was still downward after leaving the high ridge that bordered the edge of the lake, the floor of the cavern being usually smooth, although occasionally it was rough and covered with stony debris. The mysterious light grew perceptibly brighter as we progressed, the fog-like halo previously mentioned became less dense, and the ring of obscurity widened rapidly. I could distinctly perceive objects at a great distance. I turned to my companion to ask why this was, and he replied: "Because we are leaving one of the undiscovered conditions of the upper atmosphere that disturbs the sunlight." "Do you say that the atmosphere is composed of substances unknown to man?" "Yes; several of them are gases, and others are qualities of space condition, neither gas, liquid, nor solid.[11] One particularly interferes with light in its passage. It is an entity that is not moved by the motion of the air, and is unequally distributed over the earth's surface. As we ascend above the earth it decreases, so it does as we descend into it. It is not vapor of water, is neither smoke, nor a true gas, and is as yet sensible to man only by its power of modifying the intensity of light. It has no color, is chemically inactive, and yet modifies the sun's rays so as to blot objects from view at a comparatively small distance from a person on the face of the earth. That this fact is known to man is evident from the knowledge he possesses of the difference in the power of his organs of vision at different parts of the earth. His sight is especially acute on the table lands of the Western Territories." [11] This has since been partly supported by the discovery of the element Argon. However, the statement has been recorded many years. Miss Ella Burbige, stenographer, Newport, Ky., copied the original in 1887; Mr. S. D. Rouse, attorney, Covington, Ky., read it in 1889; Mr. Russell Errett, editor of the Christian Standard, in 1890, and Mr. H. C. Meader, President of the American Ticket Brokers' Association, in 1892. It seems proper to make this explanation in order to absolve the author from any charge of plagiarism, for each of these persons will recall distinctly this improbable [then] assertion.--J. U. L.
