"This is the way we measure intelligence of the inhabitants of the Earth or any of the planets. We will try to pick a non-intelligent spot on your Earth, as you would call it, without humans. Notice the color reflection upon the screen. See, this section is made up of all the various colors as you can see them in their bands, yet they are all very dull." "Now we will switch from this to a group of scientists in one of your very large laboratories. You notice the colors are still there but they are very distinct and rich." "This is the way we have, besides other delicate instruments, of finding out how far the inhabitants of any planet are advanced, as well as the type of other forms of life which may be on that planet. For everything, regardless how minute, has its own rate of life activity and throws off its own radiations or vibrations which include color. They differ in quantity and quality depending upon the purpose of the form and its development." We will soon be landing on the Moon so our little lesson in the field of science is over and we have thanked the scientists for these marvelous revelations they have given us. While we have not understood everything as we should have, we nevertheless follow its relationship to one another and the logic upon which it is founded, if no more. We must say here and now that these boys really have something on the ball, as we would say on Earth. It makes us feel quite small to think that we have given them so little credit before this adventure, thinking they knew nothing, if there even were any human beings on these other planets and pictured them in ugly forms when they excel anything and everything that we know anything about on Earth. We are now coming into view of the Moon and can almost see where our ship is. We are circling, ready to come down. The pilot has landed his ship alongside of ours and our Moonalite friends who were left in camp during our absence are running up to greet us. As we leave this ship to go to ours the natives are eager to show us what the other Martonian ship brought to them, various kinds of food and supplies. Our host who has returned with us to the Moon is telling us that the head of Mars has decided to establish an airport here, that whenever and whoever comes to the Moon from the Earth again will find better facilities in every way to greet them than we had when we landed here, but it will always remain under the flag signifying our first experience of landing on this spot. The flag which we brought has been replaced with a new flag and placed higher on the mountain. This new flag is the same as ours was except the Martonian insignia of a heart and a handshake across the heart, the same as the pilots have on their caps, is in it too. It is made of material that will not deteriorate as easily or quickly as our material would have done, and when it does deteriorate they will replace it.
