The mysteries and scenery of the cave had the same dignity that belongs to all natural objects, and which shames the fine things to which we foppishly compare them. I remarked, especially, the mimetic habit, with which Nature, on new instruments, hums her old tunes, making night to mimic day, and chemistry to ape vegetation. But I then took notice, and still chiefly remember, that the best thing which the cave had to offer was an illusion. On arriving at what is called the "Star-Chamber," our lamps were taken from us by the guide, and extinguished or put aside, and, on looking upwards, I saw or seemed to see the night heaven thick with stars glimmering more or less brightly over our heads, and even what seemed a comet flaming among them. All the party were touched with astonishment and pleasure. Our musical friends sung with much feeling a pretty song, "The stars are in the quiet sky," &c., and I sat down on the rocky floor to enjoy the serene picture. Some crystal specks in the black ceiling high overhead, reflecting the light of a half-hid lamp, yielded this magnificent effect. I own, I did not like the cave so well for eking out its sublimities with this theatrical trick. But I have had many experiences like it, before and since; and we must be content to be pleased without too curiously analyzing the occasions. Our conversation with Nature is not just what it seems. The cloud-rack, the sunrise and sunset glories, rainbows, and northern lights are not quite so spheral as our childhood thought them; and the part our organization plays in them is too large. The senses interfere everywhere, and mix their own structure with all they report of. Once, we fancied the earth a plane, and stationary. In admiring the sunset, we do not yet deduct the rounding, coordinating, pictorial powers of the eye. The same interference from our organization creates the most of our pleasure and pain. Our first mistake is the belief that the circumstance gives the joy which we give to the circumstance. Life is an ecstasy. Life is sweet as nitrous oxide; and the fisherman dripping all day over a cold pond, the switchman at the railway intersection, the farmer in the field, the negro in the rice-swamp, the fop in the street, the hunter in the woods, the barrister with the jury, the belle at the ball, all ascribe a certain pleasure to their employment, which they themselves give it. Health and appetite impart the sweetness to sugar, bread, and meat. We fancy that our civilization has got on far, but we still come back to our primers.
