“It is nearly transparent, but has a pale greenish color. It is spongy and tough, being made up of a rubber-like material full of thousands of small gas pockets. It must be this gas that keeps it afloat at this great height. It grows on long rope-like branches like sea-kelp or some kind of moss. What we took for clouds were great masses of this plant matted together and floating about. I believe we could walk on these islands, but it would be impossible to land our aeroplane for it would sink too deep to get it out again. * * * * * “We have seen a small bat-like animal fly from one island to another. Another of the same kind of creatures is flying alongside us and keeps turning its head to watch us as though it wonders what we are. I believe it is as much surprised to see us as we are to see it. Dex has just notified me that he will try to run it down and wants me to catch or kill it. We must bring down proofs or we would never dare tell of such things as are up here. Here we go--we are after the bat-like animal. Zip!--the blamed little thing is gone; it was just fooling along with us and when we whirled to reach it, it shot away like a bullet. They are too speedy for us to run down. I was close enough to see that it was nearly the size and shape of a bat, except that it had a head like a bird with large owl-like eyes, and had a beak instead of a mouth with teeth. It was of the same pale sickly green like the plants we have found. “Dex has spied something else ahead and is pointing for me to see but I fail to make it out. Now I see it. It is something long twisting through the air. It is turning and coming this way. It is another animal, or a reptile for it is more like a snake. No, not like a snake either, for it is about ten feet long and flat as can be. Its head is also formed with a beak. It looks like a huge ribbon floating through the air. It has turned and is flying above and to one side of us, looking down at us while it winds its way along. If we can get within striking distance, I will take a swipe at it with a wrench. I would like to bring it down--Look out, Dex--now--hold her steady.” The last came in a shouted command and must have been meant for Dexter, then----
