with the clean, wholesome aroma of the pines in our nostrils
throughout the day.

This Yellowstone Park is laid out like Ollendorf, in exercises of
progressive difficulty. Hell's Half-Acre was a prelude to ten or
twelve miles of geyser formation.

We passed hot streams boiling in the forest; saw whiffs of steam
beyond these, and yet other whiffs breaking through the misty
green hills in the far distance; we trampled on sulphur in
crystals, and sniffed things much worse than any sulphur which is
known to the upper world; and so journeying, bewildered with the
novelty, came upon a really park-like place where Tom suggested
we should get out and play with the geysers on foot.

Imagine mighty green fields splattered with lime-beds, all the
flowers of the summer growing up to the very edge of the lime.
That was our first glimpse of the geyser basins.

The buggy had pulled up close to a rough, broken, blistered cone
of spelter stuff between ten and twenty feet high. There was
trouble in that place--moaning, splashing, gurgling, and the
clank of machinery. A spurt of boiling water jumped into the
air, and a wash of water followed.

I removed swiftly. The old lady from Chicago shrieked. "What a
wicked waste!" said her husband.

I think they call it the Riverside Geyser. Its spout was torn
and ragged like the mouth of a gun when a shell has burst there.
