I suppose everybody who reads this paper has visited one or more observatories, and of course knows all about them. But as it may hereafter be translated into some foreign tongue and circulated among barbarous, but rapidly improving people, people who have as yet no astronomers among them, it may be well to give a little notion of what kind of place an observatory is.

To begin then: a deep and solid stone foundation is laid in the earth, and a massive pier of masonry is built up on it. A heavy block of granite forms the summit of this pier, and on this block rests the equatorial telescope. Around this structure a circular tower is built, with two or more floors which come close up to the pier, but do not touch it at any point. It is crowned with a hemispherical dome, which, I may remark, half realizes the idea of my egg-shell studio. This dome is cleft from its base to its summit by a narrow, ribbon-like opening, through which is seen the naked sky. It revolves on cannon-balls, so easily that a single hand can move it, and thus the opening may be turned towards any point of the compass. As the telescope can be raised or depressed so as to be directed to any elevation from the horizon to the zenith, and turned around the entire circle with the dome, it can be pointed to any part of the heavens. But as the star or other celestial object is always apparently moving, in consequence of the real rotatory movement of the earth, the telescope is made to follow it automatically by an ingenious clock-work arrangement. No place, short of the temple of the living God, can be more solemn. The jars of the restless life around it do not disturb the serene intelligence of the half-reasoning apparatus. Nothing can stir the massive pier but the shocks that shake the solid earth itself. When an earthquake thrills the planet, the massive turret shudders with the shuddering rocks on which it rests, but it pays no heed to the wildest tempest, and while the heavens are convulsed and shut from the eye of the far-seeing instrument it waits without a tremor for the blue sky to come back. It is the type of the true and steadfast man of the Roman poet, whose soul remains unmoved while the firmament cracks and tumbles about him. It is the material image of the Christian; his heart resting on the Rock of Ages, his eye fixed on the brighter world above.

I did not say all this while we were looking round among these wonders, quite new to many of us. People don't talk in straight-off sentences like that. They stumble and stop, or get interrupted, change a word, begin again, miss connections of verbs and nouns, and so on, till they blunder out their meaning. But I did let fall a word or two, showing the impression the celestial laboratory produced upon me. I rather think I must own to the “Rock of Ages” comparison. Thereupon the “Man of Letters,” so called, took his pipe from his mouth, and said that he did n't go in “for sentiment and that sort of thing. Gush was played out.”

The Member of the Haouse, who, as I think, is not wanting in that homely good sense which one often finds in plain people from the huckleberry districts, but who evidently supposes the last speaker to be what he calls “a tahlented mahn,” looked a little puzzled. My remark seemed natural and harmless enough to him, I suppose, but I had been distinctly snubbed, and the Member of the Haouse thought I must defend myself, as is customary in the deliberative body to which he belongs, when one gentleman accuses another gentleman of mental weakness or obliquity. I could not make up my mind to oblige him at that moment by showing fight. I suppose that would have pleased my assailant, as I don't think he has a great deal to lose, and might have made a little capital out of me if he could have got a laugh out of the Member or either of the dummies,—I beg their pardon again, I mean the two undemonstrative boarders. But I will tell you, Beloved, just what I think about this matter.

We poets, you know, are much given to indulging in sentiment, which is a mode of consciousness at a discount just now with the new generation of analysts who are throwing everything into their crucibles. Now we must not claim too much for sentiment. It does not go a great way in deciding questions of arithmetic, or algebra, or geometry. Two and two will undoubtedly make four, irrespective of the emotions or other idiosyncrasies of the calculator; and the three angles of a triangle insist on being equal to two right angles, in the face of the most impassioned rhetoric or the most inspired verse. But inasmuch as religion and law and the whole social order of civilized society, to say nothing of literature and art, are so founded on and pervaded by sentiment that they would all go to pieces without it, it is a word not to be used too lightly in passing judgment, as if it were an element to be thrown out or treated with small consideration. Reason may be the lever, but sentiment gives you the fulcrum and the place to stand on if you want to move the world. Even “sentimentality,” which is sentiment overdone, is better than that affectation of superiority to human weakness which is only tolerable as one of the stage properties of full-blown dandyism, and is, at best, but half-blown cynicism; which participle and noun you can translate, if you happen to remember the derivation of the last of them, by a single familiar word. There is a great deal of false sentiment in the world, as there is of bad logic and erroneous doctrine; but—it is very much less disagreeable to hear a young poet overdo his emotions, or even deceive himself about them, than to hear a caustic-epithet flinger repeating such words as “sentimentality” and “entusymusy,”—one of the least admirable of Lord Byron's bequests to our language,—for the purpose of ridiculing him into silence. An overdressed woman is not so pleasing as she might be, but at any rate she is better than the oil of vitriol squirter, whose profession it is to teach young ladies to avoid vanity by spoiling their showy silks and satins.

The Lady was the first of our party who was invited to look through the equatorial. Perhaps this world had proved so hard to her that she was pained to think that other worlds existed, to be homes of suffering and sorrow. Perhaps she was thinking it would be a happy change when she should leave this dark planet for one of those brighter spheres. She sighed, at any rate, but thanked the Young Astronomer for the beautiful sights he had shown her, and gave way to the next comer, who was That Boy, now in a state of irrepressible enthusiasm to see the Man in the Moon. He was greatly disappointed at not making out a colossal human figure moving round among the shining summits and shadowy ravines of the “spotty globe.”

The Landlady came next and wished to see the moon also, in preference to any other object. She was astonished at the revelations of the powerful telescope. Was there any live creatures to be seen on the moon? she asked. The Young Astronomer shook his head, smiling a little at the question.—Was there any meet'n'-houses? There was no evidence, he said, that the moon was inhabited. As there did not seem to be either air or water on its surface, the inhabitants would have a rather hard time of it, and if they went to meeting the sermons would be apt to be rather dry. If there were a building on it as big as York minster, as big as the Boston Coliseum, the great telescopes like Lord Rosse's would make it out. But it seemed to be a forlorn place; those who had studied it most agreed in considering it a “cold, crude, silent, and desolate” ruin of nature, without the possibility, if life were on it, of articulate speech, of music, even of sound. Sometimes a greenish tint was seen upon its surface, which might have been taken for vegetation, but it was thought not improbably to be a reflection from the vast forests of South America. The ancients had a fancy, some of them, that the face of the moon was a mirror in which the seas and shores of the earth were imaged. Now we know the geography of the side toward us about as well as that of Asia, better than that of Africa. The Astronomer showed them one of the common small photographs of the moon. He assured them that he had received letters inquiring in all seriousness if these alleged lunar photographs were not really taken from a peeled orange. People had got angry with him for laughing at them for asking such a question. Then he gave them an account of the famous moon-hoax which came out, he believed, in 1835. It was full of the most bare-faced absurdities, yet people swallowed it all, and even Arago is said to have treated it seriously as a thing that could not well be true, for Mr. Herschel would have certainly notified him of these marvellous discoveries. The writer of it had not troubled himself to invent probabilities, but had borrowed his scenery from the Arabian Nights and his lunar inhabitants from Peter Wilkins.

After this lecture the Capitalist stepped forward and applied his eye to the lens. I suspect it to have been shut most of the time, for I observe a good many elderly people adjust the organ of vision to any optical instrument in that way. I suppose it is from the instinct of protection to the eye, the same instinct as that which makes the raw militia-man close it when he pulls the trigger of his musket the first time. He expressed himself highly gratified, however, with what he saw, and retired from the instrument to make room for the Young Girl.

She threw her hair back and took her position at the instrument. Saint Simeon Stylites the Younger explained the wonders of the moon to her,—Tycho and the grooves radiating from it, Kepler and Copernicus with their craters and ridges, and all the most brilliant shows of this wonderful little world. I thought he was more diffuse and more enthusiastic in his descriptions than he had been with the older members of the party. I don't doubt the old gentleman who lived so long on the top of his pillar would have kept a pretty sinner (if he could have had an elevator to hoist her up to him) longer than he would have kept her grandmother. These young people are so ignorant, you know. As for our Scheherezade, her delight was unbounded, and her curiosity insatiable. If there were any living creatures there, what odd things they must be. They could n't have any lungs, nor any hearts. What a pity! Did they ever die? How could they expire if they didn't breathe? Burn up? No air to burn in. Tumble into some of those horrid pits, perhaps, and break all to bits. She wondered how the young people there liked it, or whether there were any young people there; perhaps nobody was young and nobody was old, but they were like mummies all of them—what an idea —two mummies making love to each other! So she went on in a rattling, giddy kind of way, for she was excited by the strange scene in which she found herself, and quite astonished the Young Astronomer with her vivacity. All at once she turned to him.

Will you show me the double star you said I should see?
