Many a warm summer day had the ephemeron insect frolicked round the oak tree's head—lived, moved about, and found itself happy; and when the little creature reposed for a moment in calm enjoyment on one of the great fresh oak leaves, the tree always said,—

"Poor little thing! one day alone is the span of thy whole life. Ah, how short! It is very sad."

"Sad!" the ephemeron always replied. "What dost thou mean by that? Everything is so charming, so warm and delightful, that I am quite happy."

"But for only one day; then all is over."

"All is over!" exclaimed the insect. "What is the meaning of 'all is over?' Is all over with thee also?"

"No; I may live, perhaps, thousands of thy days, and my lifetime is for centuries. It is so long a period that thou couldst not calculate it."

"No, for I do not understand thee. Thou hast thousands of my days, but I have thousands of moments to be happy in. Is all the beauty in the world at an end when thou diest?"

"Oh! by no means," replied the tree. "It will last longer—much, much longer than I can conceive."

"Well, I think we are much on a par, only that we reckon differently."

And the ephemeron danced and floated about in the sunshine, and enjoyed itself with its pretty little delicate wings, like the most minute flower—enjoyed itself in the warm air, which was so fragrant with the sweet perfumes of the clover-fields, of the wild roses in the hedges, and of the elder-flower, not to speak of the woodbine, the primrose, and the wild mint. The scent was so strong that the ephemeron was almost intoxicated by it. The day was long and pleasant, full of gladness and sweet perceptions; and when the sun set, the little insect felt a sort of pleasing languor creeping over it after all its enjoyments. Its wings would no longer carry it, and very gently it glided down upon the soft blade of grass that was slightly waving in the evening breeze; there it drooped its tiny head, and fell into a calm sleep—the sleep of death.
