We have seen such a manifestation, as most people have, at one time or another in our own homes, when after we have given our rooms a thorough cleaning, dust would be impossible to detect yet a ray of sunshine coming in through some opening would illumine dust particles flying by the billions through space within the room. That is how the screen operates here. And if you watch these dust particles floating in the light of the sun in your own room, you would see that there is a law operating there as well, for one minute they seem to turn to one side and another minute to another side, and if you watch them closely, you can see the differences in reflections. One would be brighter, another duller and another would be shadowed, and so on, depending on which way your particles would be turning in unison and the way the light would strike them. This is exactly what the screen is showing us here now except it is giving us the mineral contents in a color reflection. And the scientist says here, "unless we had a filter system to filter out this effect between us and another body we could not get a correct reading of the other body's minerals, since space is just filled with these particles of dust, some in cloud formations others just travelling around through space. "This is the major obstacle to be overcome by scientists of astronomy on Earth, for there is much now being said in reference to many bodies and the various other formations in space that is less than half true because of this type of interference that is being attracted by the various instruments that Earth men have. And since the magnifying system is largely used, it also magnifies the interference." We asked them how this could be eliminated? "Through instruments that serve more than one purpose," was the reply. And he continued, "when Earth man grows to the true purpose of his service, this will then be given unto him, to know the truth." Dr. Johnston said this would take much time, probably, why could we not be given this by the Martonians now since they already have it? He answered, "you must earn it as we have, and when you do alter your ways it will be given unto you, but we do want you to know that you are not getting the true understanding of the bodies that you daily observe through your instruments. By including all branches of science in any one branch, you can learn all these things quickly."
