The sun is the great source of light and heat for our earth. If the sun were to go somewhere for a few weeks for relaxation and rest, it would be a cold day for us. The moon, too, would be useless, for she is largely dependent on the sun. Animal life would soon cease and real estate would become depressed in price. We owe very much of our enjoyment to the sun, and not many years ago there were a large number of people who worshiped the sun. When a man showed signs of emotional insanity, they took him up on the observatory of the temple and sacrificed him to the sun. They were a very prosperous and happy people. If the conqueror had not come among them with civilization and guns and grand juries they would have been very happy, indeed. THE STARS. There is much in the great field of astronomy that is discouraging to the savant who hasn't the time nor the means to rummage around through the heavens. At times I am almost hopeless, and feel like saying to the great yearnful, hungry world: "Grope on forever. Do not ask me for another scientific fact. Find it out yourself. Hunt up your own new-laid planets, and let me have a rest. Never ask me again to sit up all night and take care of a new-born world, while you lie in bed and reck not." I get no salary for examining the trackless void night after night when I ought to be in bed. I sacrifice my health in order that the public may know at once of the presence of a red-hot comet, fresh from the factory. And yet, what thanks do I get? Is it surprising that every little while I contemplate withdrawing from scientific research, to go and skin an eight-mule team down through the dim vista of relentless years? Then, again, you take a certain style of star, which you learn from Professor Simon Newcomb is such a distance that it takes 50,000 years for its light to reach Boston. Now, we will suppose that after looking over the large stock of new and second-hand stars, and after examining the spring catalogue and price list, I decide that one of the smaller size will do me, and I buy it. How do I know that it was there when I bought it? Its cold and silent rays may have ceased 49,000 years before I was born and the intelligence be still on the way. There is too much margin between sale and delivery. Every now and then another astronomer comes to me and says: "Professor, I have discovered another new star and intend to file it. Found it last night about a mile and a half south of the zenith, running loose. Haven't heard of anybody who has lost a star of the fifteenth magnitude, about thirteen hands high, with light mane and tail, have you?" Now, how do I know that he has discovered a brand new star? How can I discover whether he is or is not playing and old, threadbare star on me for a new one? [Illustration: 0256]
