There was a sound of sliding ladders on the walls outside. The workmen had finished their task. A moment later a great bell overhead rang mellowly; the colossal sphere trembled and rocked and then rose and swung easily forward like the car of a balloon.

“We are rising,” said the Alphian, in a tone of superstitious awe. Johnston said nothing. There was a cool, sinking sensation in his stomach and his head was swimming. Branasko, however, was in possession of all his faculties.

“We shall soon be through the shaft we first discovered and throw our light over Alpha.” As he spoke the space about them broke into blinding brightness and for a few moments they could only open their eyes for an instant at a time. After a while Branasko opened the closet door and they went up the stairs.

The first apartment they entered was most luxuriously furnished. Sofas, couches and reclining-chairs were scattered here and there over the elegant carpet, and statues of gold and marble stood in alcoves and niches and strange stereopticon lanterns, hanging from the ceiling threw ever-changing and life-like pictures on the walls. The light streamed in from without through small circular windows. After they had walked about the room for some minutes, the Alphian pointed to a half-open door and a staircase at one side of the room.

“I think it leads to some sort of observatory on top,” he said. “I have heard that when the royal family makes this voyage they are fond of looking out from it. Suppose we see.” Johnston acquiesced, and Branasko opened the door. From the increased brightness that came in they were assured that the stairs led outward.

Ascending many flights of stairs and traversing a narrow winding gallery which seemed to be gradually sloping upward, they finally reached the outside, and found themselves on a platform about forty feet square surrounded by iron balustrades. Above hung impenetrable blackness, below curved a majestic sphere of white light.

“Have they assigned you a chamber yet?” she paused to ask.
