Our National Park.

Our National Park.
THE reservation which Congress has
wisely made on the Yellowstone River for
the purpose Of National Park is likely
to be ranked as one Of the wonders of the
| world. Between the Yellowstone and the
Gallatin the divide is formed of vOcan.
lc cOnglOmerate, which has been worn by

mass of columns and pinnacles, beyond
number. Little streams wind their way
through these conglOmerates, and here
and there deep gorges, cut down to the
metamorphic rocks, intervene. Every
where opalized or silicitied wood abounds,
and one instance is recorded where the
stump of a tree, thirteen or fourteen feet
in diameter, may be seen entirely inclosed
IN the breccia. The question has been
suggested by the Government biologists.
from whence these breccia came, and I'm
der what conditions they were deposited
since hey are sometimes from four to i've
thousan feet thick, and lying in perfect,
ly hOriz 'ntal strata. 1t concludes tha
they were thrown out by volcanoes into
water; thus assuming that at a compare
lively recent date the mountain ranges OF
the Northwest were submerged This
latter supposition is shown by other evi
dence to be sound, and we may suggest t.
Mr.. Hayden, that the explanation he fur
nishes of the deposition of the breccia
may be seen illustrated from time to time
in Hawaii. During the great eruption
from Kilauea, in 1859, vast quantities Of
breccia thrown into the sea fell
upon bottom of similar material
that had pro ably been many
years in &C umulating; and i'll
one instance flood of molten lava fol-
lowed, CONF l-tely filling up a small bay,
and at the same time engulfng a native
village. Any subsequent elevation Of the
land round this great volcano of the
Sandwich group would probably present
at future day much the appearance
which we now see pres rived to us in the
region OF our National Park, and in a
more marked degree than could be had in
any other volcanic region, thus fully cor
roborating Mr.. Hayden's theory.
One of the most curious features of
this region is to be found in the hot
springs. On the bOrler of the Yellow
stone Lake are often to be seen elevated
mounds, which jut out from the shore
into the water. These contain pools filled
with heated water, SO that it is possible
for a person standing on the mound to
catch trout in the lake with the help Of a
| tishingrod, and to cook them in the boil
ing spring without taking them off the
hook. The water in these springs varies
much in temperature, from 104 degrees to
about 162 degrees, their elevation above
the sea-level ranging from $3.50 to 6,779
feet, at least those which have been more
| closely examined The springs Of the high

quently sulphuretted hydrogen, though
| from some half dozen of them carbOnic
acid only is detected. 1t would seem
| that they are constantly undergoing
changes, old springs drying up and new
ones coming into existence.
There is evidence that these springs
were once much more numerous then they
now are, and a probability that they will
one day become extinct. There is an
other variety found in the eighborhood
which, although less picturesque, are
otherwise as interesting. These are mud
springs or salses. The temperature of the
water in these is often below that of the
surrounding atmosphere, and sometimes
as high as 100 degrees Fahrenheit In one
instance they cover the entire hillside,
bubbling and steaming from top to bot
tom. The mud is of various cOlOrs-black
and red from the deposit of iron, and yell
low from the presence Of native sulphur,
while in consistency it varies from thick
pasty mass to inky black water. II bub-
bles and boils necessarily from the escape
of steam and sulphuretted hydrogen,
which fill the air, and this, together with
the splashing of the water, the heavier
bubbling OF the thick mud, and the throb-

combine to form scene not readily to be

| Some of the most beautiful features in
the scenery, apart from these geological
| curiosities, are the falls of the Yellowstone
River. The lower of these, at the had of
the Grand Canyon, is found to be 397 feet
in height, and the depth of the canyon at
its foot 675 feet, increasing rapidly to
1000 feet Before the fall the river sud-
denly narrows, becomes very deep and as
sumes a remarkable green color. Large
| powders are sometimes carried over the
| precipice, as though they were mere peb-
| bless yet so great is the height that be-
| fore the water reaches the bottom it has
/ resolved itself into. a dense cloud of
spray, which, gathering itself together
again, soon after rushes between its
mountain walls, battling against the in
iervening rocks, as bri ght emerald green
stream, dashed only at intervals with a
wreath of snow-white foam. The upper
| fall is distant from this not more than
half a mile, and is 140 feet high, but
chiefly remarkable for the peculiar form
which the water in its descent assumes in
meeting with number Of great project
ing rocks. More picturesque again than
| this are some beautiful falls on Cascade
Creek, near by. The stream, after pass
ing through deep, gloomy gorge, makes
leap of about twenty-one feet, and then
| falls again in three streams distance of
over fifty feet into beautiful rounded
basin, in which the water is perfectly
smooth and quiet, but oat of which it

! into the river
The beauties Of our National Park are,

Gus, that our care must be, not how to I'M

serve the treasures which nature has so
