We say Nature knows best, and has adapted this or that to our wants or to our constitution,—sound to the ear, light and color to the eye; but she has not done any such thing, but has adapted man to these things. The physical cosmos is the mould, and man is the molten metal that is poured into it. The light fashioned the eye, the laws of sound made the ear; in fact, man is the outcome of Nature and not the reverse. Creatures that live forever in the dark have no eyes; and would not any one of our senses perish and be shed, as it were, in a world where it could not be used?

It is well to let down our metropolitan pride a little. Man thinks himself at the top, and that the immense display and prodigality of Nature are for him. But they are no more for him than they are for the birds and beasts, and he is no more at the top than they are. He appeared upon the stage when the play had advanced to a certain point, and he will disappear from the stage when the play has reached another point, and the great drama will go on without him. The geological ages, the convulsions and parturition throes of the globe, were to bring him forth no more than the beetles. Is not all this wealth of the seasons, these solar and sidereal influences, this depth and vitality and internal fire, these seas, and rivers, and oceans, and atmospheric currents, as necessary to the life of the ants and worms we tread under foot as to our own? And does the sun shine for me any more than for yon butterfly? What I mean to say is, we cannot put our finger upon this or that and say, Here is the end of Nature. The Infinite cannot be measured. The plan of Nature is so immense,—but she has no plan, no scheme, but to go on and on forever. What is size, what is time, distance, to the Infinite? Nothing. The Infinite knows no time, no space, no great, no small, no beginning, no end.

I sometimes think that the earth and the worlds are a kind of nervous ganglia in an organization of which we can form no conception, or less even than that. If one of the globules of blood that circulate in our veins were magnified enough million times, we might see a globe teeming with life and power. Such is this earth of ours, coursing in the veins of the Infinite. Size is only relative, and the imagination finds no end to the series either way.

Looking out of the car window one day, I saw the pretty and unusual sight of an eagle sitting upon the ice in the river, surrounded by half a dozen or more crows. The crows appeared as if looking up to the noble bird and attending his movements. "Are those its young?" asked a gentleman by my side. How much did that man know—not about eagles, but about Nature? If he had been familiar with geese or hens, or with donkeys, he would not have asked that question. The ancients had an axiom that he who knew one truth knew all truths; so much else becomes knowable when one vital fact is thoroughly known. You have a key, a standard, and cannot be deceived. Chemistry, geology, astronomy, natural history, all admit one to the same measureless interiors.

I heard a great man say that he could see how much of the theology of the day would fall before the standard of him who had got even the insects. And let any one set about studying these creatures carefully, and he will see the force of the remark. We learn the tremendous doctrine of metamorphosis from the insect world; and have not the bee and the ant taught man wisdom from the first? I was highly edified the past summer by observing the ways and doings of a colony of black hornets that established themselves under one of the projecting gables of my house. This hornet has the reputation of being a very ugly customer, but I found it no trouble to live on the most friendly terms with her. She was as little disposed to quarrel as I was. She is indeed the eagle among hornets, and very noble and dignified in her bearing. She used to come freely into the house and prey upon the flies. You would hear that deep, mellow hum, and see the black falcon poising on wing, or striking here and there at the flies, that scattered on her approach like chickens before a hawk. When she had caught one, she would alight upon some object and proceed to dress and draw her game. The wings were sheared off, the legs cut away, the bristles trimmed, then the body thoroughly bruised and broken. When the work was completed, the fly was rolled up into a small pellet, and with it under her arm the hornet flew to her nest, where no doubt in due time it was properly served up on the royal board. Every dinner inside these paper walls is a state dinner, for the queen is always present.

I used to mount the ladder to within two or three feet of the nest and observe the proceedings. I at first thought the workshop must be inside,—a place where the pulp was mixed, and perhaps treated with chemicals; for each hornet, when she came with her burden of materials, passed into the nest, and then, after a few moments, emerged again and crawled to the place of building. But I one day stopped up the entrance with some cotton, when no one happened to be on guard, and then observed that, when the loaded hornet could not get inside, she, after some deliberation, proceeded to the unfinished part and went forward with her work. Hence I inferred that maybe the hornet went inside to report and to receive orders, or possibly to surrender her material into fresh hands. Her career when away from the nest is beset with dangers; the colony is never large, and the safe return of every hornet is no doubt a matter of solicitude to the royal mother.

The hornet was the first paper-maker, and holds the original patent. The paper it makes is about like that of the newspaper; nearly as firm, and made of essentially the same material,—woody fibres scraped from old rails and boards. And there is news on it, too, if one could make out the characters.

When I stopped the entrance with cotton, there was no commotion or excitement, as there would have been in the case of yellow-jackets. Those outside went to pulling, and those inside went to pushing and chewing. Only once did one of the outsiders come down and look me suspiciously in the face, and inquire very plainly what my business might be up there. I bowed my head, being at the top of a twenty-foot ladder, and had nothing to say.
