round, having diameters of about twenty and twenty-five feet, the sides
being corrugated and funnel-shaped, and at the depth of thirty feet
opening out into a cavern of unfathomable depth, the rim of the spring
having beautifully escalloped edges. It does not boil over, but a very
small stream of water flows from it, and it is not affected in its
appearance by the spouting of the geyser in its immediate proximity.
There is evidently no connection between this spring and the geyser.

The "Giant" is a rugged deposit presenting in form a miniature model of
the Colosseum. It has an opening three feet in diameter. A remarkable
characteristic of this geyser is the duration of its discharges, which
yesterday afternoon continued for more than an hour in a steady stream
about three feet in diameter and one hundred and forty feet high.

Opposite our camp, on the east side of the Firehole river, is a
symmetrical cone resembling an old-fashioned straw beehive with the top
cut off. It is about five feet in diameter at its base, with an
irregular oval-shaped orifice having escalloped edges, and of
twenty-four by thirty-six inches interior diameter. No one supposed that
it was a geyser, and until this morning, among so many wonders, it had
escaped a second notice. Suddenly, while we were at breakfast this
morning, a column of water shot from it, which by quite accurate
triangular measurement proved to be two hundred and nineteen feet in
height. Our method of triangulation was as follows: A point on the
surface of the ground was marked, which was in a direct line with a
branch of a tree near by, and of the top of the column of water when at
its greatest height. Having obtained the perpendicular height of the
branch of the tree from the ground, and the distance from this
perpendicular to the point of observation and to the geyser cone, we
were enabled to make a very accurate calculation of the height of the
column of water. We named this geyser the "Bee Hive."

Near by is situated the "Giantess," the largest of all the geysers we
saw in eruption. Ascending a gentle slope for a distance of sixty yards
we came to a sink or well of an irregular oval shape, fifteen by twenty
feet across, into which we could see to the depth of fifty feet or more,
but could discover no water, though we could distinctly hear it gurgling
and boiling at a fearful rate afar down this vertical cavern. Suddenly
it commenced spluttering and rising with incredibl
