appears that it did not form in the same
manner as most others; on account of the absence of sink holes, the
regular arrangement of the chambers, the regular dip of the rock to the
south-east from five to ten degrees, and the regularity of the long
vertical fissures running north-west south-east. In fact, the whole cave
is made up of these fissures and it seems that the water has entered
narrow crevices opened by some eruptive force.

"You see small holes eaten in the ceilings and walls in every direction,
which indicates that the water came from a higher level, and being under
great pressure, wanted passage out. It seems the cave was a reservoir
for a long time, then after the water stopped flowing in it slowly
receded, and in settling the overcharged waters covered the rocks and
specimens with a calcareous coating, very thin in the upper portions of
the cave and getting thicker the deeper you go, giving evidence as you
see, of slowly settling. Had the waters rushed out they would in all
probability have left the rocks uncoated as in all other caves, with one
exception, the Crystal Cave, some seventy-five miles to the north of
Wind Cave.

"As we have some more caves to see we must journey on.

"Taking one last look at Monte Cristo's Diamonds we pass into Milliner's
Avenue, a very pretty avenue indeed with nearly as many colors as a
milliner's show-window would present. About mid-way of this avenue we
cross the bridge over Castle Garden, a room in the eighth tier beneath
the surface. From this avenue we step into the Assembly Room. Here the
formations are covered with a gypsum crystal that sparkles with
wonderful brilliancy. On the right is a passage leading to the Masonic
Temple, a room that any body of Masons would be proud of could they hold
lodge meetings in it. The passage on the left is the terminus of the
Pearly Gates' Route, the longest developed route in the cave. After
moving along some distance we see the Bad Lands, and then come into the
Tennis Court. This room has the net in the ceiling and I suppose the
party can furnish the raquet (racket). On the right hand side of this
room there is tier upon tier of box work; looking to the left, you
shudder at the almost bottomless pit just beside the pathway. Here we
take a rest preparatory to climbing up to the Marble Quarry, a task of
two flights of stairs. This is a very large room and has the most uneven
floor, ceiling and walls of any that our visitors see, a
