found themselves in a vast cave which was dimly
lighted by the tiny grains of radium that lay
scattered among the loose rocks.

"Now," said Diksey, when they had all regained
their feet, "I will show you where the dark well
is. This is a big place, but if we hold fast to
each other we won't get lost."

They took hold of hands and the Horner led
them into a dark corner, where he halted.

"Be careful," said he warningly. "The well is
at your feet."

"All right," replied Ojo, and kneeling down
he felt in the well with his hand and found
that it contained a quantity of water. "Where's
the gold flask, Dorothy?" he asked, and the
little girl handed him the flask, which she had
brought with her.

Ojo knelt again and by feeling carefully in
the dark managed to fill the flask with the
unseen water that was in the well. Then he
screwed the top of the flask firmly in place and
put the precious water in his pocket.

"All right!" he said again, in a glad voice;
"now we can go back."
