etting down the
lanthorn, the light from which shot beneath it, and showed a rich
purply-black stain, as the guide set the great hexagon up on end.

"Why, that is the finest I have seen," said Dale, growing quite excited
over his discovery. "This and two or three more will be a load for the
mule."

"Yes, herr, as many as we can get over the rocks with; but we can make
many journeys backwards and forwards now we have found the place. But
the herr will not take all away without sending word to Lucerne or
Geneva?"

"You may trust me," said Dale. "I shall behave quite honourably to the
Government, who will, I have no doubt, consent to my keeping some of
them. Now, then: we shall have a long, slow journey back, with such a
load. Try and strike off that small white piece."

The "small white piece" proved to be ten inches long and very heavy,
when it had been dexterously struck off, without damaging any of its
clearly-cut angles.

Two more very beautifully clear pieces were then selected, and then Dale
looked questioningly at Melchior.

"If the mule carries the two largest pieces, herr," he said, smiling,
"and we take one each, I think it will be all we can do. When we get
lower down, on to the better way, the mule can carry all."

"Yes, we must not be too grasping," said Dale, with a sigh. "I wish,
Saxe, I had all these over in England safe."

"I should like to have the whole grotto over there safe," replied Saxe.

"Better say the mountain while you are about it," cried Dale, with a
laugh. "There, Melchior, try if you can get down that heavy piece."

"Yes, herr, easily done," said the guide; and, drawing up the rope, he
made it fast to the largest crystal and carefully lowered it down.

"You must go down now and unfasten," said Dale. "I can lower the rest.
But what about the rope when we have done?"

For answer Melchior climbed up and loosened the rope, leaving only a
loop over the spike. Then sliding down, he soon set the crystal free,
and the others were lowered down. Dale and Saxe followed, and the rope
was jerked off the spike and coiled up.

"The only way of locking up the door," said Saxe, laughing. "But, I
say, these will be very heavy to carry back. What's the matter?" he
continued, as he saw Dale looking at the fragments of broken rock sent
down by Melchior.

"I was thinking that those pieces will tell tales," he said. "If any
one comes up here, they will see we have been at work."

"
