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.
