Swiftly they drew near to the flaming colored suns, and passed close
beside them. The light was then so bright that it dazzled their eyes,
and they covered their faces with their hands to escape being blinded.
There was no heat in the colored suns, however, and after they had
passed below them the top of the buggy shut out many of the piercing
rays so that the boy and girl could open their eyes again.

"We've got to come to the bottom some time," remarked Zeb, with a deep
sigh. "We can't keep falling forever, you know."

"Of course not," said Dorothy. "We are somewhere in the middle of the
earth, and the chances are we'll reach the other side of it before
long. But it's a big hollow, isn't it?"

"Awful big!" answered the boy.

"We're coming to something now," announced the horse.

At this they both put their heads over the side of the buggy and
looked down. Yes; there was land below them; and not so very far
away, either. But they were floating very, very slowly--so slowly
that it could no longer be called a fall--and the children had ample
time to take heart and look about them.

They saw a landscape with mountains and plains, lakes and rivers, very
like those upon the earth's surface; but all the scene was splendidly
colored by the variegated lights from the six suns. Here and there
were groups of houses that seemed made of clear glass, because they
sparkled so brightly.
