succeeded, until 1877, when he died
and left a fortune of $2,000,000 to seventeen wives and fifty-six
children. Here they prospered and started to build the great temple,
which is not yet quite finished.]

[Illustration: PULPIT TERRACE, YELLOWSTONE NATIONAL PARK.-The
Yellowstone Park has in the vicinity of the Mammoth Hot Springs
many remarkable terrace-building springs, which are situated one
thousand feet above the Gardiner River, into which they discharge
their waters. The water finds its way to the surface through deep-lying
cretaceous strata, and contains a great deposit of calcareous material.
As the water flows out at the various elevations on the terraces
through many vents, it forms corrugated layers of carbonate of
lime, which is generally hard while wet, but becomes soft when dry.
While these springs are active, vegetation dies in their vicinity;
but when dry, grass and trees again grow on the crumbling calcareous
deposit.]

[Illustration: OBSIDIAN CLIFF, YELLOWSTONE NATIONAL PARK.--This
noted and volcanic glass mountain, situated in the Yellowstone
Park, glistens like jet, is opaque and rises like basalt in almost
vertical columns, from the shore of Beaver Lake. It is unequalled
in the world, and is about two hundred feet high and one thousand
feet in length, being variegated with streaks of red and yellow.
When the carriage road was constructed over the side of the mountain
along the lake, great fires were built upon the masses of Obsidian;
and after they had been sufficiently expanded by the heat, cold
water was thrown on them, which fractured the blocks into fragments
that could be handled. Thus a glass carriage way was made one-quarter
of a mile in length, which is without doubt the only piece of glass
road in the world.]

[Illustration: MAMMOTH PAINT POTS, YELLOWSTONE NATIONAL PARK.--Among
all the geysers and hot springs in Yellowstone Park, there is nothing
more striking to behold than the Mammoth Paint Pots, which measure
forty by sixty feet, with a mud rim on three sides from three to
four feet in height. The whitish substance in this basin, which
looks like paint, is in constant agitation, and resembles a vast bed
of mortar with numerous points of ebullition. There is a constant
bubbling up of this peculiar formation, which produces a sound
similar to a hoarse whisper. Its contents have been reduced by
the constant action to a mixed silicious clay, which in former
years consisted of different
