Lately Made BY SIR JOHN HERSCHEL, L.L.D, F.R.S, &c. At The Cape of Good Hope. [From Supplement to the Edinburgh Journal of Science] [Continued from yesterday's Sun]
"The astonishing and beautiful discoveries which we had
made during our first night's observation, and the brilliant
promise which they gave of the future, rendered every
moonlight hour too precious to reconcile us to the
deprivation occasioned by those two cloudy evenings; and
they were borne with strictly philosophical patience,
notwithstanding that our attention was closely occupied in
superintending the erection of additional props and braces
to the twenty-four feet lens, which we found had somewhat
vibrated in a high wind that arose on the morning of the
11th.
The night of the 13th (January) was one of pearly
purity and loveliness. The moon ascended the firmament in
gorgeous splendor, and the stars, retiring around her, left
her the unrivalled queen of the hemisphere. This being the
last night but one, in the present month, during which we
should have an opportunity of inspecting her western limb,
on account of the libration in longitude which would thence
immediately ensue, Dr. Herschel informed us that he should
direct our resources to the parts numbered 2, 11, 26 and 20
in Blunt's map, and which are respectively known in the
modern catalogue by the names of Endymion, Cleomedes,
Langrenus, and Petavius. To the careful inspection of these,
and the regions between them and the extreme western rim, he
proposed to devote the whole of this highly favorable night.
Taking then our twenty-five miles breadth of her surface
upon the field of view, and reducing it to a slow movement,
we soon found the first very singularly shaped object of our
inquiry.
It is a highly mountainous district, the loftier chains
of which form three narrow ovals, two of which approach each
other in slender points, and are united by one mass of hills
of great length and elevation; thus presenting a figure
similar to that of a long skein of thread, the bows of which
have been gradually spread open from their connecting knot.
The third oval looks also like a skein, and lies as if
carelessly dropped from nature's hand in connection with the
other; but that which might fancifully be supposed as having
formed the second bow of this second skein is cut open, and
lies in scattered threads of smaller hills which cover a
great extent of level territory.
The ground plan of these mountains is so remarkable
that it has been accurately represented in almost every
lineal map of the moon that has been drawn; and in Blunt's,
which is the best, it agrees exactly with my description.
Within the grasp, as it were, of the broken bow of hills
last mentioned, stands an oval-shaped mountain, enclosing a
valley of an immense area, and having on its western ridge a
volcano in a state of terrific eruption. To the north-east
of this, across the broken, or what Mr. Holmes called `the
vagabond mountains,' are three other detached oblong
formations, the largest and last of which is marked F in the
catalogue, and fancifully denominated the Mare Mortuum, or
more commonly the `Lake of Death.'
Induced by a curiosity to divine the reason of so
sombre a title, rather than by any more philosophical
motive, we here first applied our hydro-oxygen magnifiers to
the focal image of the great lens. Our twenty-five miles
portion of this great mountain circus had comprehended the
whole of this area, and of course the two conical hills
which rise in it about five miles from each other; but
although this breadth of view had heretofore generally
presented its objects as if seen within a terrestrial
distance of two and a half miles, we were, in this instance,
unable to discern these central hills with any such degree
of distinctness. There did not appear to be any mist or
smoke around them, as in the case of the volcano which we
had left in the south-west, and yet they were completely
indistinct upon the canvass. On sliding in the gas-light
lens the mystery was immediately solved. They were old
craters of extinct volcanoes, from which still issued a
heated though transparent exhalation, that kept them in an
apparently oscillatory or trembling motion, most unfavorable
to examination. The craters of both these hills, as nearly
as we could judge under this obstruction, were about fifteen
fathoms deep, devoid of any appearance of fire, and of
nearly a yellowish while color throughout. The diameter of
each was about nine diameters of our painted circle, or
nearly 450 feet; and the width of the rim surrounding them
about 1000 feet; yet notwithstanding their narrow mouths,
these two chimneys of the subterranean deep had evidently
filled with lava and ashes with which it was encumbered, and
even added to the height, if not indeed caused the existence
of the oval chain of mountains which surrounded it.
These mountains, as subsequently measured from the
level of some large lakes around them, averaged the height
of 2,800 feet; and Dr. Herschel conjectured from this and
the vast extent of their abutments, which ran for many miles
into the country around them, that these volcanoes must have
bee in full activity for a million years. Lieut. Drummond,
however, rather supposed that the whole area of this oval
valley was but the exhausted crater of one vast volcano,
which in expiring had left only these two imbecile
representatives of its power. I believe Dr. Herschel himself
afterwards adopted this probable theory, which is indeed
confirmed by the universal geography of the planet. There
is scarcely a hundred miles of her surface, not excepting
her largest seas and lakes, in which circular or oval
mountainous ridges may not be easily found; and many, very
many of these having numerous enclosed hills in full
volcanic eruption, which are now much lower than the
surrounding circles, it admits of no doubt that each of
these great mountains is the remains of one vast mountain
which has burnt itself out, and left only these wide
formations of its ancient grandeur. A direct proof of this
is afforded in a tremendous volcano, now in its prime, which
I shall hereafter notice.
What gave the name `The Lake of Death' to the annular
mountain I have just described, was, I suppose, the dark
appearance of the valley which it encloses, and which, to a
more distinct view than we obtained, certainly exhibits the
general aspect of the waters on this planet. The
surrounding country is fertile to excess: between this
circle and No. 2 (Endymion), which we proposed first to
examine, we counted not less than twelve luxuriant forests,
divided by open plains, which waved in an ocean of vendure,
and were probably prairies like those of North America. In
three of these we discovered numerous herds of quadrupeds
similar to our friends the bisons in the Valley of the
Unicorn, but of much larger size; and scarcely a piece of
woodland occurred in our panorama which did not dazzle our
visions with flocks of white or red birds upon the wing.
"At length we carefully explored the Endymion. We
found each of the three ovals volcanic and sterile within;
but, without, most rich, throughout the level regions around
them, in every imaginable production of a bounteous soil.
Dr. Herschel has classified not less than thirty-eight
species of forest trees, and nearly twice this number of
plants, found in this tract alone, which are widely
different to those found in more equatorial latitudes. Of
animals, he classified nine species of mammalia, and five of
ovipara. Among the former is a small kind of rein-deer, the
elk, the moose, the horned bear, and the biped beaver. The
last resembles the beaver of the earth in every other
respect than in its destitution of a tail, and its
invariable habit of walking upon only two feet. It carries
its young in its arms like a human being, and moves with an
easy gliding motion. Its huts are constructed better and
higher than those of many tribes of human savages, and from
the appearance of smoke in nearly all of them, there is no
doubt of its being acquainted with the use of fire. Still
its head and body differ only in the points stated from that
of the beaver, and it was never seen except on the borders
of lakes and rivers, in which is has been seen to immerse
for a period of several seconds.
"Thirty degrees farther south, in No. 11, or Cleomedes,
an immense annular mountain, containing three distinct
craters, which have been so long extinguished that the whole
valley around them, which is eleven miles in extent, is
densely crowded with woods nearly to the summits of the
hills. Not a rod of vacant land, except the tops of these
craters, could be descried, and no living creature, except a
large white bird resembling the stork. At the southern
extremity of this valley is a natural archway or cavern, 200
feet high, and 100 wide, through which runs a river which
discharges itself over a precipice of grey rock 80 feet in
depth, and thus forms a branching stream through a beautiful
campaign district for many miles.
Within twenty miles of this cataract is the largest
lake, or rather inland sea, that has been found throughout
the seven and a half millions of square miles which this
illuminated side of the moon contains. Its width, from east
to west, is 198 miles, and from north to south, 266 miles.
Its shape, to the northward, is not unlike that of the bay
of Bengal, and it is studded with small islands, most of
which are volcanic. Two of these, on the eastern side, are
now violently eruptive; but our lowest magnifying power was
too great to examine them with convenience, on account of
the cloud of smoke and ashes which beclouded our field of
view: as sen by Lieut. Drummond, through our reflective
telescope of 2,000 times, they exhibited great brilliancy.
In a bay, on the western side of this sea, is an island 55
miles long, of a crescent form, crowded through its natural
sweep with the most superb and wonderful natural beauties,
both of vegetation and geology. Its hills are pinnacled
with tall quartz crystals, of so rich a yellow and orange
hue that we at first supposed them to be pointed flames of
fire; and they spring up thus from smooth round brows of
hills which are covered with a velvet mantle. Even in the
enchanting little valleys of this winding island we could
often see these splendid natural spires, mounting in the
midst of deep green woods, like church steeples in the vales
of Westmoreland.
We here first noticed the lunar palm-tree, which
differs from that of our tropical latitudes only in the
peculiarity of very large crimson flowers, instead of the
spadix protruded from the common calyx. We, however,
perceived no fruit on any specimens we saw: a circumstance
which we attempted to account for from the great
(theoretical) extremes in the lunar climate. On a curious
kind of tree-melon we nevertheless saw fruit in great
abundance, and in every stage of inception and maturity.
The general color of these woods was a dark green, though
not without occasional admixtures of every tint of our
forest seasons. The hectic flush of autumn was often seen
kindled upon the cheek of earliest spring; and the gay
drapery of summer in some places surrounded trees leafless
as the victims of winter. It seemed as if all the seasons
here united hands in a circle of perpetual harmony.
Of animals we saw only an elegant striped quadruped
about three feet high, like a miniature zebra; which was
always in small herds on the green sward of the hills; and
two or three kinds of long-tailed birds, which we judges to
be golden and blue pheasants. On the shores, however, we
saw countless multitudes of univalve shell-fish, and among
them some huge flat ones, which all three of my associates
declared to be cornu ammonae; and I confess I was here
compelled to abandon my sceptical substitution of pebbles.
The cliffs all along these shores were deeply undermined by
tides; they were very cavernous, and yellow crystal
stalactites larger than a man's thigh were shooting forth on
all sides. Indeed every rood of this island appeared to be
crystallized; masses of fallen crystals were found on every
beach we explored, and beamed from every fractured headland.
It was more like a creation of an oriental fancy than a
distinct variety of nature brought by the powers of science
of ocular demonstration.
The striking dissimilitude of this island to every
other we had found on these waters, and its near proximity
to the main land, led us to suppose that it must at some
time have been a part of it; more especially as its crescent
bay embraced the first of a chain of smaller ones which ran
directly thither. The first one was a pure quartz rock,
about three miles in circumference, towering in naked
majesty from the blue deep, without either shore or shelter.
But it glowed in the sun almost like a sapphire, as did all
the lesser ones of whom it seemed the king. Our theory was
speedily confirmed; for all the shore of the main land was
battlemented and spired with these unobtainable jewels of
nature; and as we brought our field of view to include the
utmost rim of the illuminated boundary of the planet, we
could still see them blazing in crowded battalions as it
were, through a region of hundreds of miles. If fact we
could not conjecture where this gorgeous land of enchantment
terminated; for as the rotary motion of the planet bore
these mountain summits from our view, we became further
remote from their western boundary.
"We were admonished by this to lose no time in seeking
the next proposed object of our search, the Langrenus, or
No. 26, which is almost within the verge of the libration in
longitude, and of which, for this reason, Dr. Herschel
entertained some singular expectations.
