VI.

_KILLARNEY._

The total amount of heat which the sun sends annually to the earth is

invariable, and hence if any portion of the earth’s surface during

any given year be colder than ordinary, we may infer with certainty

that some other portion of the surface is then warmer than ordinary.

The port of Odessa owes its importance to a case of atmospheric

compensation of this kind. Forty or fifty years ago, Western Europe

received less than its normal amount of heat; the missing sunbeams

fell upon the East, and Odessa became, to some extent, the granary

from which the hungry West was fed. The position it then assumed it

has since maintained. The atmosphere is the grand distributor of heat.

It has its cold and warm currents--vast aërial rivers, which chill or

cheer according to the proximate sources from which they are derived.

In this present year 1860 the British Isles appear to lie near the

common boundary of two such currents--the limit, however, shifting

so as to cause both to pass over us in swift succession. Near this

boundary line the atmospheric currents mingle, and the copious aqueous

precipitation which we now observe is the result.

Superadded to this source of general rain, we have at Killarney local

condensers in the neighbouring mountains. Round the cool crests of

Carrantual and his peaked and craggy brothers the moist and tilted

south-west wind curdles ceaselessly into clouds, which nourish the

moss and heather whose decomposition produces the peat which clothes

the disintegrated rocks. Grandly the vast cumuli build themselves

in the atmosphere, hanging at times lazily over the mountains and

mottling with their shadows the brown sides of the hills. Reddened

by the evening sun, these clouds cast their hues upon the lakes, the

crisped surface of which breaks up their images into broad spaces of

diffused crimson light. On other days the cumuli seem whipped into

dust, and scattered through the general air, mixing therewith as the

smoke of London mingles with the supernatant atmosphere. Day by day the

guides prophesy fine weather--the blackest cloud is ‘all for hate.’

You are assured that if you start to-day you will not get ‘a single

dhrop’ of rain; you go, and are drenched; but the guide’s purpose is

accomplished, the moderate sum of three and sixpence being added to his

private store.

In ages past these mountain condensers acted differently. The wet winds

of the ocean, which now descend in liquid showers upon the hills, once

discharged their contents as snow. And a famous deposit they must have

made. In addition to the charms which this region presents to every

eye, the mind of him who can read the rocks aright is carried back to a

time when deep snowbeds cumbered the mountain-slopes, and vast glaciers

filled the vales. In neither England nor Wales do the traces of glacial

action reach the magnitude which they exhibit here.

The Gap of Dunloe is the channel of an ancient glacier; and all through

it the scratching and polishing may be traced. The flanks of the

Purple Mountain have been planed down by the moving ice, and the rocky

amphitheatre which the guides choose for the production of echoes has

been scooped and polished by the same agency. Near the point where the

road from the Gap joins that up the Black Valley is a slab of rock,

which rivals the famous _Höllen Platte_ in Haslithal. The Black Valley,

indeed, was the mould through which a great glacier from the adjacent

mountains moved, ‘unhasting, unresting,’ grinding the rocks right and

left, and filling the entire basin now occupied by the waters of the

Upper Lake. All the islands of this lake are glacier domes. The shapes,

moreover, which have suggested the fanciful names given to some of the

rocks are entirely due to the planing of the ice. The ‘Cannon Rock,’

the ‘Giant’s Coffin,’ the ‘Man-of-War,’ and others, owe their forms to

the mighty moulding-plane which in bygone ages passed over them.

I have spoken of the echoes in the Gap of Dunloe. They are very fine,

and are usually awakened by a guide who plays a bugle, and to whom

extra wages are paid on this account. The man times his operations so

that the echo and the original sound shall not overlap, and he usually

places his guests behind a hill-brow, which partially cuts away the

direct sound, but offers no impediment to the echoes. He flourishes his

trumpet, and pauses; the rocks respond, the first return of the sound

being almost as strong as the blast itself; the sonorous pulses leap

from crag to crag, and from them to the listener’s ear, diminishing in

intensity and augmenting in softness the oftener they are reflected.

Moore’s melody of ‘The Meeting of the Waters,’ suitably played, is thus

returned with exquisite sweetness by the reflecting rocks.

The rain here is pitiless, but the march of the showering clouds over

the mountains is sometimes very grand. One really good day is all that

I have been able to number out of six spent on the banks of the Lower

Lake, and even that day was ushered in by heavy rain. Afterwards,

however, the cloud field broke, and the condensed vapours rolled

themselves up into sphered masses, which sailed majestically through

the ether. With some other visitors I rowed to the Upper Lake, landed

at the base of the Purple Mountain, and with one companion climbed the

latter to its crest. This is covered by loose masses of stone of a

purplish hue, from which the mountain derives its name.

A few days previously I had been on the top of Mangerton, a spot

selected by the guides as affording a prospect of the entire region

of the Lakes. But Mangerton is a stupid mountain, and it is climbed

by a wearisome pony track. It is incomparably inferior to the Purple

Mountain. From the latter, on one side, we look into the heart of

Magillicuddy’s Reeks, and shake hands with Carrantual across the

Gap of Dunloe. It commands a splendid mountain panorama, and on the

occasion of my visit showed the Reeks in their true character, as

cloud-generators. A light wind swept across them. Far to westward,

towards the sea, the air was cloudless; but over the Reeks its moisture

was densely precipitated, and formed there a canopy which threw an

inky gloom upon the mountains. The clouds sometimes descended so as

to touch the summits, but for the most part they floated a little way

above them, leaving the jagged outlines clear. From the Reeks the

clouds were wafted westward; but here, meeting with warmer air, they

diminished in size, the smaller ones melting quite away. Below us

gleamed the Upper Lake, running in and out amid the mountains, fringed

with woods and studded with islands covered with sunny foliage. From

this lake a long, sinuous, and narrow outlet, called the Long Range,

runs to the Middle Lake. The suddenness with which this lovely sheet of

water opens on quitting the Long Range constitutes perhaps the greatest

surprise which the traveller here encounters.

We walked along the ridge of the Purple Mountain ankle deep in elastic

moss, with glorious views at either side. Arrived at the end of its

greatest spur, the Middle and Lower Lakes with their islands, and the

wooded and tortuous peninsula between them, lay before us. No view of

the English lakes known to me could compete in loveliness with this

one. We passed onward through the heather to the brow above the Bay of

Glena, and there clambered down the mountain, helping ourselves by the

trees which grasped with gnarled roots the mossed and slippy crags.

At Glena we met our boat, and were rowed over the jerking waves to

the island of Innisfallen, and thence to our hotel. Various bits of

climbing were accomplished during my stay, and almost in every case

in opposition to the guides. The Eagle Rock, for example, a truly

noble mass, and others, were climbed, amid emphatic enunciations of

‘impossible.’ Yet these guides and boatmen are fine, hardy fellows, and

of great endurance, but they appear averse to trying their strength

under new conditions.

I write on a drenching day, and a strong wind which wails dismally

round the house has roused the Lower Lake to foam and fury. Innisfallen

looms feebly through the grey haze, but the opposite Toumies mountains

are plunged in impenetrable gloom. All round the horizon is built a

black cloud-wall, but the zenithal heaven is clear. Over the coping

of this thunderous bulwark the sun shoots his rays, which, meeting

the dropping cloud of the opposite heaven, paint upon it a complete

and magnificent bow. Here the white beam enters the front of the

falling drop, and is reflected at its back, emerging unravelled to its

component hues. But the condition is, that after being thus unravelled,

the coloured rays shall not diverge on quitting the drop. If they did,

they would be lost immediately to the senses; but they are squeezed

together to parallel sheaves, and thus their intensity is preserved

through long aërial distances. Above the vivid bow hangs its spectral

secondary brother, in which a double reflection within each raindrop

enfeebles the colours, and inverts the order of succession.

Touched by the wand of law, the dross of facts becomes gold, the

meanest being raised thereby to brotherhood with the highest. Thus the

smoke of an Irish cabin lifts our speculations to the heavenly dome.

We look through the cloudless air at the darkness of infinite space,

and are met by the azure of the firmament--we look through a long reach

of the same atmosphere at the bright sun or moon and see them orange

or red. We look through the peat-smoke at a black rock, or at the dark

branches of a yew, and see the smoke blue--we look through the same

smoke at a cloud illuminated to whiteness by the sun and find the smoke

red. The selfsame column of smoke may be projected against a bright

and a dark portion of the same cloud, and thus made to appear blue

and red at the same time. The blue belongs to the light _reflected_

from the smoke; the red to the light _transmitted_ through it. In like

manner, the hues of the atmosphere are not due to colouring matter, but

to the fact of its being a turbid medium. Through this we look at the

blackness of unillumined space and see the blue; at the western heaven

at sunset, and meet that light which steeps the clouds of evening in

orange and crimson dyes.
