While the infant sits drawing milk, with never a dream of solid food, the teeth are growing beneath its gums. And while we crawl around here now, with no conception of our future state, some of the forces at work among us are preparing for the days when real life shall begin. Among these forces you may count the constructors of the great cosmic eye--the huge telescope that is now building in Paris. Compared with all other exhibits at the Paris Fair, that great instrument will be as a giant among babies, a Corliss engine among children's toys. It is the precursor of the great instruments which in the future will take man on his travels through space. Imperfect as it is, it fills the mind with awe and the imagination with delight. ---- Think of the great celestial eye, flint and crown glass lenses more than four feet in diameter, weighing a ton, and suspended at the end of a tube one hundred feet long! It will reach out thousands of billions of miles into space, giving us, perhaps, new secrets of the universe. Yet it is but a child's toy compared to the instruments which must follow it. And you who read this, if your mind is fresh and your imagination not jaded, may be the man who shall add to the power of this instrument as Galileo added to that given to the world by Lippershey, the humble Dutchman. We invite the young American of ambition to study this latest proof of man's growing skill, and see whether he can imagine anything to add to it. ---- "I have not seen it" say you. If you are the right man, you do not need to SEE it. Galileo only HEARD of Lippershey's discovery. He thought hard on the problems of refraction for one night, and as a result produced a telescope capable of magnifying threefold. He finally produced a telescope of thirty-two-fold power. This French telescope magnifies six thousand times, but it is only a baby telescope, full of faults. It is rendered imperfect by the wavy motion of the air, which affects our sight just as the motion of the waves affects the sight of a fish. It lacks any adequate arrangement for light supply. The great trouble of the astronomer is the getting of more light in his telescopes. You may be the man to tell him how to do it without adding to the diameter of his object glass. Anyhow, think about the big telescope. If it does not make you an astronomer or a great inventor, it may stir up your brain to the pitch of inventing a really good chicken coop. That is still lacking, and in great demand. WHAT ANIMAL CONTROLS YOUR SPIRIT? Of all animals upon earth man came last. All of earth's animal creations are bound up in man. As to the first statement there is no difference of opinion. The Bible and Darwin agree that man was created last of all the animals. Very superficial observation will convince you that man contains in his mental make-up all of the "inferior" animals, or at least a great many of them.
