The following excerpts in regards to the Incas are from a letter which appeared in the "Discussions' section of the Jan. 1948 issue of AMAZING STORIES magazine:
"Sirs... INCAS refers to the Incan Kings or emperors, supposedly children of the Sun; INCANS refers to the subjects of the INCAS... For those of you who may not know it...Tiahuanaco and Cuzco (capital of Incan civilization) are just across Lake Titicaca from each other (Cuzco being some slight distance back from the lake).
"In regard to the underground passages at Cuzco, I have been told again and again by natives and some foreign investigators that there are subterranean passages in the neighborhood of Cuzco which are STILL GUARDED. Men have actually been known to try to enter these passages and either disappear or turn up dead.
"Rather than attribute this to deros (this is not sarcasm, as I find Shaverism very much worthy of study) I would attribute it to the zeal of the Indians to guard the treasures of the past to which they feel they are the rightful heirs. Separately, someday, I hope to present a treatise on why I believe the Treasure of the Incas exists today near Cuzco and that it could not be valued at much less than seventy-five millions of dollars, but that is a lengthy subject. There is much to support the possibility of the existence of the underground passages to which Mr. Hansen (L. Taylor Hansen - Branton) refers, because, among other evidences, it is known that the Incas had secret ways of traveling great distances under ground. A friend of mine (a Peruvian miner with twenty years experience among the Quichua Indians in the Andean highlands) has actually discovered the entrance to one of these royal passages. The floor is paved with tile. He went back as far as he could go without suffocating.
"The air is too stale and there is considerable danger of cave- ins. The Incans were very clever, but I don't believe at all that they had the means to bore tunnels for thousands of miles through the mountains. Rather, if they covered such distances underground, it can only mean that their man-made passages were only entrances into a series of CAVERNS. After earthquakes in the hills and in Lima (as long as twenty minutes after) you can sometimes hear subterranean rumblings, as though the sound were the result of subterranean landslides in deep caverns below.
"Indeed one time in Lima I heard a subterranean landslide WITHOUT the accompaniment of earthquake. The ground merely vibrated in a light and curious fashion for perhaps a minute, to the accompaniment of the muffled, subterranean sound of sliding rocks. Ask the Indians in the hills. They'll tell you at once about the rumblings under ground...
"Here is one item to add to the collection. When I was seventeen I built myself a four-inch Newtonian telescope. In examining the moon one night I distinctly saw five symmetrical bodies travel slowly in formation across the moon's disc, as though they were gigantic bodies traveling closer to the moon than to the Earth. My wife laughingly accuses me now of having mistaken flies on my mirror for space ships, but if she knew more about optical laws she would know that flies on my mirror would have been far more invisible to me than if she had put them in my soup..."
The writer of the letter then commences to quote from a scene in Shakespeare's HAMLET: 'There are stranger things in Heaven and Earth than are dreamt of in your philosophy, my dear Horatio...'
