In this balloon journey I had a specially advantageous opportunity of observing the two moons—velnaa, as they are called. Cavelna, or Caulna, the nearer, in diameter about 8' or a little more than one-

fourth that of our Moon, is a tolerably brilliant object, about 5000 miles from the surface. Moving, like all planets and satellites, from west to east travel industry statistics, it completes its stellar revolution and its phases in

less than seven and a half hours; the contrary revolution of the skies prolongs its circuit around the planet to a period of ten hours. Zeelna (Zevelna) returns to the same celestial meridian in thirty

hours; but as in this time the starry vault has completed about a rotation and a quarter in the opposite direction, it takes nearly five days to reappear on the same horizon. It is about 3' in diameter, and

about 12,000 miles from the surface. The motions is that the two moons, to the eye, seem to move in opposite directions. When we rose above the mists, Caulna was visible as a very fine

crescent in the west; Zeelna was rising in the east, and almost full marketing diploma; but hardly a more brilliant object than Venus when seen to most advantage from Earth. Both moved so rapidly among the stars that their

celestial change of place was apparent from minute to minute. But, as regarded our own position, the appearance was as opposite as their direction. Zeelna, traversing in twelve hours only one-fifth of the

visible hemisphere, while crossing in the same time 144° on the zodiac—twelve degrees per hour, or our Moon's diameter in two minutes and a half&mdash endocare ampoules;was left behind by the stars; and fixing what I may call the ocular attention on her, she seemed to stand still while they slowly passed her; thus making their revolution perceptible to sense as it never is on Earth, for lack of a similar standard. Caulna, rising in the west and moving eastwards, crossed the visible sky in five hours, and passed through the stars at the rate of 48° per hour, so that she seemed to sail past them like a golden cloudlet or celestial vessel driven by a slow wind. It happened this night that she passed over the star Fomalhaut—an occultation which I watched with great interest through an excellent field-glass, but which lasted only for about half a minute. About an hour before midnight the two moons passed each other in the Eastern sky; both gibbous at the moment, like our Moon in her last quarter. The difference in size and motion was then most striking; Caulna seeming to rush past her companion, and the latter looking like a stationary star in the slowly moving sky.

CHAPTER XXV - APOSTACY.
We were received on landing by our former host and conducted to his house. On this occasion, however, I was not detained in the hall, but permitted at once to enter the chamber allotted to us. Eveena, who had exacted from me all that I knew, and much that I meant to conceal, respecting the occasion of our journey, was much agitated and not a little alarmed. My own humble rank in the Zinta rendered so sudden and imperative a summons the more difficult to understand, and though by this time well versed in the learning, neither of us was familiar with the administration of the Brotherhood. I was glad therefore on her account, even more than on my own, when, a scratch at the door having obtained admission for an amba, it placed before me a message from Esmo requesting a private conference. Her father's presence set Eveena's mind at rest; since she had learned, strangely enough from myself, what she had never known before, the rank he held among the brethren.
