"How do I know? Perhaps one mile—perhaps ten."

"If it is two, the hedgehogs will burn through before I get there," replied Curtis. "I'm going down."

"It is very dangerous," replied Michali.

"We must yust take our chances," asserted Lindbohm.

The descent was not so difficult as it appeared. Within twelve feet of the bottom they found themselves on the edge of a rock. Below them the stream gurgled enticingly between banks of snowy sand.

"And now?" asked Curtis.

"We must yust yump and take our chances," replied Lindbohm. Instinctively seizing the tails of his coat he held them out like wings and sprang into the air.

"Hurrah!" he cried, looking up. "It's all right," and throwing himself flat on his stomach, he sucked up long drafts of the cool, refreshing water. In a moment Michali and Curtis were lying beside him.

"How do the goats get out of here?" asked Curtis, looking at the face of the rock down which he had just made a flying leap.

"O, a goat is like a fly; he can skip up a pane of glass," replied Lindbohm.
