The experts of Stazza have learned the art of slicing metallic blocks into sheets of any desired thickness. These sheets serve the same purpose for them as paper does for us, and are furnished at an insignificant cost of labor. We have the very elements in our Earth to produce these metallic blocks if we knew the combination, which might be easily found if we had as much need for them as the people of this water world. The metallic blocks are used for a great variety of purposes. There are some high class artists who have immortalized themselves by their master-pieces, one of which I saw on a five-cornered metallic sheet measuring about eight feet in diameter. Perhaps the most surprising feature of the educational advancement of these water spirits is their knowledge of astronomy. To them, under the water, the stars have always looked beautiful, and from an early date in their history a study of them has engaged the attention of their scholars. No one could tell the style of their telescopes if he should go to guessing for a week. Let me give you a brief description of one. They build a metallic pipe about ten feet in diameter and from a point some two hundred feet below the surface of the water. The pipe is built until it extends a few feet above water. Inside of this pipe is a series of transparent ovals of various sizes. These ovals are so arranged that the upper one throws its light to the lower one, down through the immense cylinder. Around each oval is built a series of fin protectors, which is the only part about the telescope I could not fully understand. They seemed to counteract the refraction of the water, and yet the water must be in the pipe to obtain proper results. Imagine an astronomer at the base of this huge metallic structure, having at his finger's ends a dozen wire strings intricately connected with the oval system, and by the proper use of which he can increase or decrease the magnifying power of the ponderous telescope. The highest magnifying power of a telescope of this size is so great that the Milky Way is penetrated and its solar systems revealed. What an accomplishment it would be if a telescope of this magnitude could be mounted, a thing that these creatures never attempted to do. But they have built telescopes of various inclinations, all stationary. You can form an idea of the patience and endurance of these people when you learn that it required over fifty years of our time for them to perfect one of these large instruments. Give human brains to any animal under water or over water, and it will grasp for larger views of its Creator and of the things He made. These people are thoroughly convinced that intelligent life can be found in any world where there is enough water to sustain it.
