deepest silence. What I had taken for grave-clothes was a covering formed from the growth of their bleached and tangled locks. As I was wondering at this marvellous spectacle Urania told me this was their usual mode of interment and resurrection. Yes, on this world human beings enjoyed the organic faculty of those insects which have the gift of going to sleep in a chrysalis state, and metamorphosing themselves into winged butterflies. It is like a double human race; and the beings in the first phase, even the coarsest and most material of them, need but to die to rise again in the most splendid of transformations. Each year in this world represents about two hundred terrestrial years. Two thirds of the year is lived in the lower condition, one third (winter) in the chrysalis state, and the following spring the sleepers feel life coming back to their transformed flesh; they stir, awaken, leave their fleecy coverings on the trees, and freeing themselves from them, fly away, wonderful winged creatures, to aerial regions, there to live for a new Phœnician year,—that is, for two hundred years of our swiftly moving planet.

We crossed a great number of planets in this way, and it seemed as though all eternity would not be long enough to admit of my enjoying these creations unknown to earth; but my guide barely left me time to realize this, and still new suns and new worlds were appearing. We were very near striking against some transparent comets in our rapid flight, that were wandering about like a breath from one system to another, and more than once I felt myself strongly attracted toward wonderful planets with fresh landscapes, whose occupants would have been new objects of study. And yet the celestial Muse bore me on without fatigue still higher, still farther away, until at last we came to what seemed to me the confines of the universe. The suns grew more rare, less luminous, paler; darkness was more intense between the stars; and we were soon in the midst of an actual desert, the thousands of millions of stars which constitute the universe visible from the Earth being far distant: everything had faded to a little, lonely Milky Way in empty infinity.

"At last we have reached the very limits of creation!" I cried.

"Look!" she replied, pointing to the zenith.

IV.
ETERNITY AND THE INFINITE

WHAT was that? Could it be true? Another universe was coming down to us! Millions and millions of suns grouped together were floating about like a celestial archipelago, and as we flew toward them they spread themselves out like a limitless cloud of stars. I looked about me on all sides, trying to pierce the depths of boundless space, and saw similar clusters of twinkling stars scattered about in all directions, at various distances.

The new universe which we were entering was made up principally of red, ruby, and garnet suns. Many of them were absolutely blood-red.

It was like going through a magnificent display of lightning. We sped swiftly from sun to sun; but incessant electrical commotions like the flashes of an aurora-borealis assailed us on all sides. What strange abiding-places worlds lighted solely by red suns must be! Then, too, we saw in one section of this universe a secondary group, composed of great numbers of rose-colored and blue stars. Suddenly an enormous comet, whose head was like some monster's open jaws, rushed upon and enveloped us. I clung terror-stricken to my goddess's side, who was for a moment hidden from me by a luminous haze. We were soon in a dark desert again, for the second universe, like the first, was now far away.

"Creation," she said, "comprises an infinite number of distinct worlds, separated from each other by abysses of vacancy."

"An infinite number?"

"A mathematical objection," she answered. "Doubtless, no matter how great a number may be, it cannot be actually infinite, since by thought one can always increase by a unit, or even double, treble, centuple it. But remember that the present is but a door through which the future rushes to the past. Eternity is endless, and the number of the worlds will be like it, without end."

"Look! You still see, always and on all sides, new celestial archipelagoes,—new worlds everywhere."

"It seems to me, O Urania! that we have been ascending toward the boundless heavens for a long time, and at very great speed."

"We could rise like this forever," she answered, "and never reach a definite limit.

"We could be wafted about yonder to right, to left; forward, backward; above, below,—in no matter what direction, but never anywhere should we find any confines.

"Never, never any end!

"Do you know where we are? Do you know how we reached here?

"We are—on the threshold of the infinite, as we were when on the Earth. We have not advanced one step!"
