stive of boundless
mines in the upper hills. So the joy of finding one lost lamb in the
wilderness tells of the joy of finding and saving a human soul. One
should never go to any of God's great wonders to see sights, but to
live life; to read in them the figures, symbols, and types of the more
wonderful things in the new heavens and the new earth.

The old Hebrew prophets and poets saw God everywhere in nature. The
floods clap their hands and the hills are joyful together before the
Lord. Miss Proctor, in the Yosemite, caught the same lofty spirit, and
sang:

"Perpetual masses here intone,
Uncounted censers swing,
A psalm on every breeze is blown;
The echoing peaks from throne to throne
Greet the indwelling King;
The Lord, the Lord is everywhere,
And seraph-tongued are earth and air."

THE YELLOWSTONE PARK GEYSERS

THEIR ESSENTIAL FACTS AND CAUSES

I have been to school. Dame Nature is a most kind and skillful
teacher. She first put me into the ABC class, and advanced me through
conic sections. The first thing in the geyser line she showed me was a
mound of rock, large as a small cock of hay, with a projection on top
large as a shallow pint bowl turned upside down. In the center of this
was a half-inch hole, and from it every two seconds, with a musical
chuckle of steam, a handful of diamond drops of water was ejected to a
height of from two to five feet. I sat down with it half an hour,
compelled to continuous laughter by its own musical cachinnations.
There were all the essentials of a geyser. There was a mound, not
always existent, built up by deposits from the water supersaturated
with mineral. It might be three feet high; it might be thirty. There
was the jet of water ejected by subterranean forces. It might be half
an inch in diameter; it might be three hundred feet, as in the case of
the Excelsior geyser. It might rise six inches; it might rise two
hundred and fifty feet. There was the interval between the jets. It
might be two seconds; it might be weeks or years.

A subsequent lesson in my Progressive Geyser Reader was the "Economic."
Here was a round basin ten feet in diameter, very shallow, with a hole
in the middle about one foot across. The water was perfectly calm.
But every six minutes a sudden spurt of water and steam would rise
about thirty feet, for thirty seconds, and then settle economically,
