It is a singular thing, and another instance of the power and wisdom of God, that though the satellites of Jupiter are constantly being eclipsed, as is natural enough from their rapid revolutions around him, yet they are never all eclipsed at one time. One moon may be eclipsed, and perhaps another, or even three out of the four; but there is always one left shining; and, in like manner, God never takes away all the comfort of his people at once, there is always some ray of light to cheer them.
There is a great deal more to be learned from Jupiter; but having introduced you to him, I will leave you to examine him for yourselves, and to get all you can out of him.
Far, far beyond Jupiter is Saturn. That respectable planet has been very much slandered, but I am happy to inform you that he does not deserve such treatment. He is nearly 900,000,000 miles from the sun. I wonder whether any brother here, with a large mind, has any idea of what a million is; I do not suppose that he has, and I am sure that I have not. It takes a vast deal of thinking to comprehend what a million means; but to realize what is meant by a million miles is altogether beyond one's mental grasp. A million pins would be something enormous; but a million miles! And here we are talking of nine hundred millions of miles; well, I give up all thought of understanding what that is so long as I am in this finite state. Why, when you speak of nine hundred millions, you might as well say nine hundred billions at once; for the one term is almost as incomprehensible as the other; and yet, please to recollect that this vast space is to our great God only a mere hand's-breadth compared with the immeasurable universe that he has created.
I said that Saturn had been greatly slandered, and so he has. You know that we have, in our English language, the word "saturnine," as a very uncomplimentary description of certain individuals. When a man is praised for being very hearty and genial, he is said to be jovial, in allusion to Jove, or Jupiter, the brightly shining planet; but a person of an opposite temperament is called saturnine, because it is supposed that Saturn is a dull planet, dreadfully dreary, and that his influences are malignant and baneful. If you have read some of the astrological books which I have had the pleasure of studying, you have there been told that, if you had been born under the influence of Saturn, you might almost as well have been born under the influence of Satan, for it will come to about the same thing in the end. He is supposed to be a very slow sort of individual, his symbol is the hieroglyphic of lead; but he is really a very light and buoyant personage. His diameter is about nine times as great as that of the earth, and while in volume he is equal to 746 worlds as large as ours, his weight is equal to only 92 such globes. The densities of the planets appear to diminish according to their distance from the sun, not in regular proportion, but still very largely so; and there seems to be no reason why those which are most remote, and travel slowly, should be made so dense as those which are nearer the central orb, and revolve more quickly around him.
This useful volume, from which I have already given you several extracts, says: "Instead, therefore, of sinking like lead in the mighty waters, he would float upon the liquid, if an ocean could be found sufficiently capacious to receive him. John Goad, the well-known astro-meteorologist, declared the planet not to be such a 'plumbeous, blue-nosed fellow' as all antiquity had believed and the world still supposed. But it was the work of others to prove it. For six thousand years or so Saturn concealed his personal features, interesting family, and strange appurtenances—the magnificent out-buildings of his house—from the knowledge of mankind. But he was caught at last by a little tube, pointed at him from a slope of the Apennines, the holder of which, in invading his privacy, cared not to ask leave, and deemed it no intrusion." When that "little tube" was turned upon him he was found to be a most beautiful planet, one of the most varied and most marvelous of all the planetary worlds.
Take that as an illustration of the falseness of slander, and of how some persons are very much bemired and bespattered because people do not know them. This planet, which was so despised, turned out to be a very beautiful object indeed; and, instead of being very dull, and what the word saturnine usually means, he is bright and glorious. Saturn also has no less than eight satellites to attend him; and, in addition, he has three magnificent rings, of which Tennyson has sung:
Still as, while Saturn whirls, his steadfast shade
Sleeps on his luminous rings.
Saturn has only about a hundredth part of the light from the sun as compared with what we receive; and yet, I suppose, the atmosphere might be so arranged that he might have as much solar light as we have; but even if the atmosphere is of the same kind as ours, Saturn would still have as much light as we have in an ordinary London fog. I am speaking, of course, of the light from the sun; but then we cannot tell what illuminating power the Lord may have put in the planet himself; and beside that, he has his eight moons, and his three shining rings, which have a brilliance that we cannot either imagine or describe. What must it be to see a marvelous arch of light rising to a height of 37,570 miles above the planet, and having the enormous span of 170,000 miles! If you were at the equator of Saturn, you would only see the rings as a narrow band of light; but if you could journey toward the poles, you would see above you a tremendous arch, blazing with light, like some of the vast reflectors that you see hung up in large buildings where they cannot get sufficient sunlight. The reflector helps to gather up the rays of light, and throw them where they are needed; and I have no doubt that these rings act like reflectors to Saturn. It must be a wonderful world to live in if there are inhabitants there; they get compensations which fully make up for their disadvantages in being so far away from the sun. So is it in the spiritual world, what the Lord withholds in one direction he makes up in another; and those who are far removed from the means of grace and Christian privileges have an inward light and joy, which others, with greater apparent advantages, might almost envy.
Journeying again in the heavens, far, far beyond Saturn, we come to Uranus, or Herschel, as it is sometimes called, after the astronomer who discovered it in 1781. The mean distance of Uranus from the sun is believed to be about 1,754,000,000 miles; I give you the figures, but neither you nor I can have the slightest conception of the distance they represent. To an observer standing on Uranus, the sun would probably appear only as a faraway speck of light; yet the planet revolves around the sun at about 15,000 miles an hour, and occupies about eighty-four of our years in completing one journey. Uranus is said to be equal in volume to seventy-three or seventy-four earths, and to be attended by four moons. I do not know much about Uranus, therefore I do not intend to say much about him.
