ty on their backs. In one
case Rollo saw a woman bringing a load of hay on her back down the
mountain side.

The valley, bordered thus as it was with such wild and precipitous
mountain sides, might have had a gloomy, or at least a very sombre,
expression, had it not been cheered and animated by the waterfalls that
came foaming down here and there from the precipices above, and which
seemed so bright and sparkling that they greatly enlivened the scene.
These waterfalls were of a great variety of forms. In some cases a thin
thread of water, like the jet from a fire engine, came slowly over the
brink of a precipice a thousand feet in the air, and, gliding smoothly
down for a few hundred feet, was then lost entirely in vapor or spray.
In other cases, in the depth of some deep ravine far up the mountain,
might be seen a line of foam meandering for a short distance among the
rocks and then disappearing. Rollo pointed to one of these, and then
said to Mr. George,--

"Uncle, look there! There is a short waterfall half way up the mountain;
but I cannot see where the water comes from or where it goes to."

"No," said Mr. George. "It comes undoubtedly from over the precipice
above, and it flows entirely down into the valley; but it only comes out
to view for that short distance."

"Why can't we see it all the way?" asked Rollo.

"I suppose," said Mr. George, "it may flow for the rest of the way in
the bottom of some deep chasms, or it may possibly be that it comes
suddenly out of the ground at the place where we see it."

"Yes," said Rollo. "I found a great stream coming suddenly out of the
ground at Interlachen."

"Where," asked Mr. George.

"Right across the river," said Rollo. "I went over there this morning."

"How did you get over?" said Mr. George.

"I went over on a bridge," said Rollo. "I took a little walk up the
road, and pretty soon I came to a bridge which led across the river. I
went over, and then walked along the bank on the other side. There was
only a narrow space between the river and the precipice. The ground
sloped down from the foot of the precipice to the water. I found several
very large springs breaking out in this ground. One of them was _very_
large. The water that ran from it made a great stream, large enough for
a mill. It came up right out of the ground from a great hole all full of
stones. The water came up from among the stones."

"And where did it go to?" asked Mr. George.

"O, it ran
