To me, by the ancient, triple-roped,

Lone, tortuous stair, whereby I made

A tingling silence, a heavy concentric shade,

The twelve-years’ child of the Lord Llewellyn groped:

With May-wreaths laden, the loving strange child came!

And my pulses that throbbed at sight of her, ten years gone,

Chilled and recoiled at her delicate finger-touch, guessing

Along my brazen-wrought margin, the laud and the blessing

Traced, thro’ the vine, thro’ the tangle of star and of sun,

By her dead father’s name, by Llewellyn’s magnificent name.

And even as she stood in the dark, the doom and the horror rushed on me;

(I had weakened my soul, and they won me!)

I felt the desire at my vitals, the unbearable joy that is pain:

With one mad tigerish spring against the dim rafter,

I smote the sweet child in my rage, I smote her with laughter,

And a sound like the rain

Whirled east on the casement, died after:

And I knew that the life in her brain

I had quenched at the stroke, and flung even my darling of yore

Down the resonant, tottering stair, down, down to the centuried door!

Then the swift hurricane,

The clamoring army thronged up from below, my

allegiance to claim!

Lean goblins, brown-flecked like a toad, the gnomic horned ghosts,

Imps flickering, quarry-sprites grim, all the din of the dolorous hosts,

All the glory and glee of the cursèd hissed round me and round,

as a flame.

And they loosened my hold from the tower, and my hope from the hem

Of the garment of Him who could save, as they jeered! and with speed

Crashed down past the rocks and the wrecks; and the horrible deed

Was done. I was theirs; and I gave up my spirit to them.

V.

In a mossy minaret

Fathoms under, I am set.

All the sea-shapes undulating

At my gates forlorn are waiting,

All the dreary faint-eyed people

Watch me in my hollow steeple,

While the glass-clear city heaves

Oft beneath its earthy eaves.

So in sorrow, sorrow, sorrow

Yestereven and to-morrow,

Thro’ the æons, in a cell

Hangs Saint Cadoc’s loveless bell,

Orbèd, like a mortal’s tear,

On the moony atmosphere,

Bearing, the refrain of time,

Memory, and unrest, and crime.

Thou that hast the world sublime!

I that was free, I am lost, I am damned, I am here!

And whenever a child among men by a blow is dead,

Docile for aye from the deeps must I lift my head,

And from the heathen heart of me that breaks,

The unextinguishable music wakes,

Naught availing, naught deterred.

And the sailor heareth me,

Even as thou, alas! hast heard,

Fallen in awe upon thy knee,

Tolling and wailing, bursting and failing, afar in the ominous sea.

A CHOUAN.

FROM the school-porch at Vannes

Weaponed, the children ran;

One little voice began,

Lark-like ascended:

‘Treason is on the wing,

Black vows, and menacing:

March, boys! God save the King!’

Allio ended.

Singing, with sunny head,

Battleward straight he led,

Stones for his captain’s bed,

Herbs for his diet:

He and his legion brave,

Trouble enough they gave!

Ere the Blues’ bullets drave

Them into quiet.

Spared, with a few as bold,

Once the storm over-rolled,

Allio, twelve years old,

Crept from the clamor;

Came, when the days were brief,

To the old desk in grief,

Thumbing anew the leaf

Of the old grammar.

Kings out!... rang the chime,

Kings in!... answered Time.

In his ignoring clime,

Silent, he studied;

Till, ere his youth was done,

For him, the chosen one,

Shepherd disclaimed of none,

Aaron’s rod budded.

Long, in unbroken round,

Peace on his paths he found;

Saw the glad Breton ground

Husbanded, quarried:

Blessed it, the record saith,

All the years he had breath,

Till the dim eightieth

Snowed on his forehead.

President!... Emperor!...

President!... On the floor

Spake a sharp Senator

Widening his ranges:

‘From Paris I impeach

Vannes for disloyal speech;

Send thither troops to teach,

How the world changes!’

Down on the peasants then

Rode the Republic’s men,

Trampling the corn again,

Miring the flowers;

Hewed thro’ the rebels nigh,

Scoffed at the women’s cry,

Set the tricolor high

On the church towers.

Pale in his cot that day,

Dying, the pastor lay,

Where still his eye could stray

Up valleys gleaming;

Watchers were at his side;

Prayer unto prayer replied:

Hush! what was that he spied,

Pinnacle-streaming?

(Nothing was he aware

In his deaf Breton air,--

So gray traditions there

Throve unforgotten,--

That, by a final chance,

Kings all were led a dance;

Long since, in fickle France,

Sceptres were rotten!)

Sprang the old lion, still

Live with prodigious will,

To his stone casement-sill;

Foolish and true one!

Snatched up the blade he bore,

Rough with its rust of yore,

Kissed it, a saint no more--

Only a Chouan!

Barred from the charging mass

In the choked market-pass,

All he could do, alas!

Now, was to clang it:

Nay, more:--‘God save the King!’

With a last clarion ring,

Shot ere he ceased to sing,

Allio sang it.

LYRICS

YOUTH.

LET us hymn thee for our silent brothers,

Freely as the wild impellent wind blows,

Briefly, rudely, in the smoky pauses

Of a battle, in the stress and scourging

Of the sail apast thy heavenly margin;

Let us hymn thee, while the gallant pulses

In high heart and limbs one kingliest instant,

Boom and flash thy name and their allegiance;

‘Once, and for one only,’ let us hymn thee,

O Delight, O Sunrise, O sole Answer,

Empery unbought, supreme Adventure,

Youth, ah, Youth! all men’s desire and sorrow.

Let us hymn thee, we, the passing, dying,

Out of bondage by a vision lifted,

Since by chance sublime, in secret places,

Goddess! we, Aktaion-like, have seen thee.

Tho’ our voice as a spent eagle’s voice is,

Let us hymn thee, while the doom is forging;

Holding, losing, thro’ one first last moment,

One mad moment worth dull life forever,

Triumphing in anguish, let us hymn thee!

Thine, beholden Beauty, thine this heart-break,

Thine, O Hope forsworn! this salutation,

Youth, ah, Youth! all men’s desire and sorrow.

THE LAST FAUN.

HOW hath he stumbled hither, in search of love and praise,

A tardy comer and goer across the world’s highways,

A kind shape from the thicket, a wanderer all his days?

He finds a rocky seat where the moiling town recedes:

The altered shepherds flout him; but O he little heeds!

Incredulous he swings there, and drones upon his reeds.

He stamps his cloven heel, and he laughs adown the wind,

With eye that wanes and waxes at doings of mankind.

Slow, slow creeps the invader upon that happy mind.

The apple breasts his fellow; doves wheel by two and three,

And ever dance in circle the shallops on the sea;

The goats and deer are many; but playmate none hath he,

Nor nymph nor child to follow upon his signals rude;

He smiles: there is no frolic; he snarls: there is no feud.

He feels his poor heart sinking at every interlude.

His shaggy ear and freakish resents the wail and din;

Earth’s rumors chill his veins with their ghostly gliding in;

He aches to slip these tethers, and be where he hath been.

Elsewhere is waking glory, and here the dream, the thrall.

Hush! hear the sunless waters, the wrestling leaves that call!

He lops the grass, and whistles; and while he cheats them all,

Obeys, is gone, gone wholly. From alien air too cold,

The Faun, with garlands flying, with sylvan ditties trolled,

Being homesick, being patient, regains his greenwood old.

KNIGHTS OF WEATHER.

WHEN down the filmy lanes

The too wise sun goes grieving,

A wake of splendor leaving

Upbillowed from the ground;

When at the window-panes

The hooded chestnuts rattle,

And there is clash of battle

New England’s oaks around:

Oh, then we knights of weather,

We birds of sober feather,

Fill up the woods with revel

That summer’s pomp is slain;

And make a mighty shouting

For King October’s outing,

The Saracen October

Astride the hurricane!

When dappled butterflies

Have crept away to cover,

And one persistent plover

Is coaxing from the fen;

When apples show the skies

Their bubbly lush vermilion,

And from a rent pavilion

Laugh down on maids and men:

Oh, then we knights of weather,

We birds of sober feather,

Fill up the woods with revel

That summer’s pomp is slain;

And make a mighty shouting

For King October’s outing,

The Saracen October

Astride the hurricane!

When pricks the winy air;

When o’er the meadows clamber

Cloud-masonries of amber;

When brooks are silver-clear;

When conquering colors dare

The hills and cliffy places,

To hold, with braggart graces,

High wassail of the year:

Oh, then we knights of weather,

We birds of sober feather,

Fill up the woods with revel

That summer’s pomp is slain;

And make a mighty shouting

For King October’s outing,

The Saracen October

Astride the hurricane!

DAYBREAK.

THE young sun rides the mists anew; his cohorts follow from the sea.

Let Aztec children shout and sue, the Persian lend a thankful knee:

Those glad auroral eyes shall beam not anywhere henceforth on me.

Up with the banners on the height, set every matin bell astir!

The tree-top choirs carouse in light; the dew’s on phlox and lavender:

Ah, mockery! for, worlds away, the heart of morning beats with her.

ON SOME OLD-MUSIC.

TO lie beside a stream, upon the sod

At ease, while weary shepherds homeward plod,

And feel benignly by, as daylight mellows,

The mountains in their weathering period;

Aye so, with silence shod

To lie in depth of grass with man’s meek fellows,

The cattle large and calm, aware of God,

And, keen as if to flesh the spirit sprang,

To hear,--O but to hear that silvern clang

Of young hale melody! and hither rally

The thrill, the aspiration, and the pang

Again, as once it rang

Sovereign and clear thro’ all the Saco valley,

Whose slaves were we that heard, and he that sang!

Happy the spot, the hour, the spanning strain

Precious and far, the rainbow of the rain,

The seal of patience, dark endeavor’s summing,

The heaven-bright close of Pergolese’s pain!

Sighs bid it back in vain,

Nor win its peer, till craftsmen aftercoming

Lost art, lost heart, from shipwrecked years regain.

How, like an angel, it effaced the crime,

The moil and heat of our tempestuous time,

And brought from dewier air, to us who waited,

The breath of peace, the healing breath sublime!

As falls, at midnight’s chime

To an old pilgrim, plodding on belated,

The thought of Love’s remote sunshining prime.

There flits upon the wind’s wing, as we gaze,

Our northern springtime, virgin-green three days;

The racy water shallowing, the glory

Of jonquils strewn, the wafted apple-sprays:

O let it be thy praise,

Child-song too lovely and too transitory!

Thou art as they; thy feet have gone their ways.

O beauty unassailable! O bride

Of memory! while yet thou didst abide

The yester joy was ours, the joy to-morrow,

Life’s brimming whole: and since to earth denied,

Soft ebbed thy dreamy tide,

To us the first, the full, the only sorrow,

Wild as when Abel out of Eden died.

LATE PEACE.

AS a pool beset with lilies

In the May-green copses hid,

Far from wayfarers and wrongers,

Clangors, rumors, disillusions,

Neighbored by the wild-grape only,

By the hemlock’s dreamy host,

By the Rhodian nightingale,

O remote, remote, O lonely!--

So thy life is.

Whence and wherefore is it

Never peace may be co-dweller

With my lakelet

Too belovèd and too sheltered,

That, secure from broil of cities,

From a secret regnant spring

To its own wild depth awaking,

Makes but moaning and resistance,

Undiminishable protest;

Mimicking with pain and fury

Of humanity the struggle;

Fretting, foaming, pacing ever

Round and round its fragrant cloister,

All within itself perplexèd,

Every heart-vein bruised but eager;

And its clear soul, doubt-o’erladen,

’Neath the stirred and floating foulness,

Long abased, long dumb, ah! long?--

So thy life is.

Comes the respite, comes the guerdon;

The perfect truce arrives

In the honey-dropping twilight,

The southwestering pallid sunshine,

The magian clouds a-fire,

The mooring galleon-wind:

At whose spell,

Potent daily,

The lulled water is beguiled

Back to saneness, back to sweetness.

All its arrowy hissing atoms

Gather from the chase forsaken;

The sphered galaxy of bubbles,

Fragments, motes, the lees unrestful,

Disunite, as to heard music,

Like weird dancers, from their wreathings

Each to its cool grotto swaying;

Till there follows, on their fervor,

Depth, and crystal clarity.

So thy life is, so thy life!

Darkling to beatitude,

Shaken in the saving change.

And the spirit made wise, not weary

By the throes that youth endureth,

When old age falls, evening-placid,

On the mystery unriddled,

Yet in empire, yet in honor,

In submission not ignoble,

Glistens to a central quiet,

Leal to the most lovely moon.

TO A YOUNG POET.

SIGH not to be remembered, dear,

Nor for Time’s fickle graces strive;

Vex not thy spirit’s songful cheer

With the sick ardor to survive.

But be content, thou quick bright thing

A while than lasting stars more fair:

A lone high-flashing skylark’s wing

Across obliterating air.

O rich in immortality!

Not thee Fame’s graven stones benight;

But ever, to some world-worn eye,

All Heaven is bluer for thy flight.

DE MORTUIS.

THE skilfullest of mankind!

So praise him, reckoning

By shot in the sea-gull’s wing,

By doubts in boyhood’s mind.

DOWN STREAM.

SCARRED hemlock roots,

Oaks in mail, and willow-shoots

Spring’s first-knighted;

Clinging aspens grouped between,

Slender, misty-green,

Faintly affrighted:

Far hills behind,

Sombre growth, with sunlight lined,

On their edges;

Banks hemmed in with maiden-hair,

And the straight and fair

Phalanx of sedges:

Wee wings and eyes,

Wild blue gemmy dragon-flies,

Fearless rangers;

Drowsy turtles in a tribe

Diving, with a gibe

Muttered at strangers;

Wren, bobolink,

Robin, at the grassy brink;

Great frogs jesting;

And the beetle, for no grief

Half-across his leaf

Sighing and resting;

In the keel’s way,

Unwithdrawing bream at play,

Till from branches

Chestnut-blossoms, loosed aloft,

Graze them with their soft

Full avalanches!

This is very odd!

Boldly sings the river-god:

‘Pilgrim rowing!

From the Hyperborean air

Wherefore, and O where

Should man be going?’

Slave to a dream,

Me no urgings and no theme

Can embolden;

Now no more the oars swing back,

Drip, dip, till black

Waters froth golden.

Musketaquid!

I have loved thee, all unbid,

Earliest, longest;

Thou hast taught me thine own thrift:

Here I sit, and drift

Where the wind’s strongest.

If, furthermore,

There be any pact ashore,

I forget it!

If, upon a busy day

Beauty make delay,

Once over, let it!

Only,--despite

Thee, who wouldst unnerve me quite

Like a craven,--

Best the current be not so,

Heart and I must row

Into our haven!

THE INDIAN PIPE.

(TO R. L. S.)

YOUR bays shall all men bring,

And flowers the children strew you.

Once, as I stood in a thick west wood,

I took from a fissure a precious thing,

The homage whereof be to you!

A thing pearl-pale, yet stung

With fire, as the morning’s beam is;

Hid underground thro’ a solar round,

Hardy and fragile, antique and young,

More exquisite than a dream is.

No rose had so bright birth;

No gem of romance surpassed it,

By a minstrel-knight, for his maid’s delight,

Borne from the moon-burnt marge of the earth,

Where Paynim breakers cast it.

Rude-named, memorial, quaint,

The dews and the darkness mould it:

Scarce twice in an age is our heritage

This glory and mystery without taint.

Dear Stevenson, do you hold it

A text of grace, ah! much

Beyond what the praising throng say:

Only your art is its peer at heart,

Only your touch is a wonder such,

My wild little loving song says!

BROOK FARM.

DOWN the long road bent and brown,

Youth, that dearly loves a vision,

Ventures to the gates Elysian,

As a palmer from the town,

Coming not so late, so far,

Rocks and birches! for your story,

Nor to prate of vanished glory

Where of old was quenched a star;

Where, of old, in lapse of toil,

Time, that has for weeds a dower,

Bade the supersensual flower

Starve in our New England soil.

But to Youth, whose radiant eyes

Shatter mists of grief and daunting,

Lost glad voices still are chanting

’Neath those unremaining skies;

Still the dreams of fellowship

Beat their wings of aspiration;

And a smile of soft elation

Trembles from his haughty lip,

If another dare deride

Hopes heroic snapped and parted,

Disillusion so high-hearted,

All success is mean beside!

‘MY TIMES ARE IN THY HANDS.’

‘MY times are in Thy hands!’

It rumbles from the sea;

It jingles ever, inland far,

From the reddening rowan-tree.

Let me not sit inert,

Let me not be afraid!

Teach me to dare and to resist

Like the first mortal made,

To whom of fate’s dread strength

No sickening rumors ran;

Who with whatever grim event

Grappled, as man with man.

Seal to my utmost age

What now my youth hath known:

‘My times are in Thy hands,’ O most!

When wholly in my own.

GARDEN CHIDINGS.

THE spring being at her blessed carpentry,

This morning makes a stem, this noon a leaf,

And jewels her sparse greenery with a bud;

Fostress of happy growth is she. But thou,

O too disdainful spirit, or too shy!

Passive dost thou inhabit, like a mole,

The porch elect of darkness; for thy trade

Is underground, a barren industry,

Shivering true ardor on the nether air,

Shaping the thousandth tendril, and all year

Webbing the silver nothings to and fro.

What wonder if the gardener think thee dead,

When every punctual neighbor-root now goes

Adventurously skyward for a flower?

Up, laggard! climb thine inch; thyself fulfil;

Thou only hast no sign, no pageantry,

Save these fine gropings: soon from thy small plot

The seasonable sunshine steals away.

FRÉDÉRIC OZANAM.

UNTO the constant heart whom saints befriend

Afar in peace, what were our gaudy praise?

His course is ended, and his faith is kept.

Honor in silence to that memory! sweet

Equally in the forum of the schools,

And in the sufferer’s hovel. His, threefold,

The lowliness of Isai’s chosen son,

And zeal that fired the warring Macchabee,

About him like a wedding-garment, worn

The day of his acceptance; and we know

That for the sake of some such soul as this,--

So brave, so clean, compassionate and just,

Alert in its most meek security,--

Love beareth yet with all that stains the world.

BANKRUPT.

PAST the cold gates, a wraith without a name,

Sullen and withered, like a thing half-tame

Still for its jungle moaning, came by night,

Before the Judgment’s awful Angel came.

‘Answer, Immortal! at my high decree

Glory or shame shall flood thee as the sea:

What of the power, the skill, the graciousness,

The star-strong soul the Lord hath lent to thee?’

But the lone spectre raised a mournful hand:

‘Call me not that! Release me from this land!

What words are Heaven and Hell? They fall on me

As on a sphere the fooled and slipping sand.

‘Discerning, thou the good mayst yet belie,

By some last test, the sinner sanctify.

My guilt is neutral-safe, like innocence:

No boon nor bane of deathless days gain I,

‘Whose life is hollow shell and broken bowl,

Of all which was its treasury, the whole

Utterly, vilely squandered. O most Just!

Put down thy scales: for I have spent my soul.’

A REASON FOR SILENCE.

YOU sang, you sang! you mountain brook

Scarce by your tangly banks held in,

As running from a rocky nook,

You leaped the world, the sea to win,

Sun-bright past many a foamy crook,

And headlong as a javelin.

Now men do check and still your course

To serve a village enterprise,

And wheelward drive your sullen force,

What wonder, slave! that in no wise

Breaks from you, pooled ’mid reeds and gorse,

The voice you had in Paradise?

TEMPTATION.

I COME where the wry road leads

Thro’ the pines and the alder scents,

Sated of books, with a start,

Sharp on the gang to-day:

Scarce see the Romany steeds,

Scarce hear the flap of the tents,

When hillo! my heart, my heart

Is out of its leash, and away.

Gypsies, gypsies, the whole

Tatterdemalion crew!

Brown and sly and severe

With curious trades in hand.

A string snaps in my soul,

The one high answer due

If an exile chance to hear

The songs of his fatherland.

... To be abroad with the rain,

And at home with the forest hush,

With the crag, and the flower-urn,

And the wan sleek mist upcurled;

To break the lens and the plane,

To burn the pen and the brush,

And, clean and alive, return

Into the old wild world!...

How is it? O wind that bears

The arrow from its mark,

The sea-bird from the sea,

The moth from his midnight lamp,

Fate’s self, thou mocker of prayers!

Whirl up from the mighty dark,

And even so, even me

Blow far from the gypsy camp!

FOR A CHILD.

Schumann’s ‘Erinnerung: Novbr. 4, 1847.’

IN memory of dear Mendelssohn, the loving song I made

Fain would I sing for you, my own, but that I am afraid,

Aye, truly, sore afraid:

For sweet as was its every tone, once freed to mortal ears,

In memory of dear Mendelssohn, the ghostly wand of tears

Would yet be strong to break my song,

Thro’ all these after-years!

AGLAUS.

THE ash hath no perfidious mind;

The open fields are just and kind;

Tho’ loves betray, I hear this way

The feathery step of the faithful wind.

Thorn-apple, bayberry and rose

Around me, talismanic, close:

The frosty flakes, the thunder-quakes,

Are bulwarks twain of my year’s repose.

No struggle, no delight, no moan,

But at my hearthstone I have known!

All thoughts that pass, as in a glass

The gods have bared to me for mine own.

Wisdom, the sought and unpossessed,

Hath of her own will been my guest;

Not smoking feud, but quietude

My heart hath chosen, at her behest.

‘This is of men the happiest man

Who hath his plot Arcadian,’

Apollo cried, my gates beside,

‘Nor ever wanders beyond its span.’

Now, like my sheep, I seek the fold;

My hair is shaken in the cold;

The night is nigh; but ere I die,

Bear witness, brothers! that young and old,

My name I wear without regret:

The Home-Keeper am I, and yet

At every inn my feet have been,

Above all travellers I am set.

Tho’ ocean currents by me purled,

The sails of my desire were furled.

What pilgrims crave, three acres gave;

And I, Aglaus, have seen the world!

AN AUDITOR.

WHY chide me that mutely I listen, ah, jester?

For either thou knowest

Too much, or thou knowest not aught of this aching vexed

planet down-whirling:

Thou knowest?--Thy wit is but fortitude; would’st have me

laugh in its presence?

Thou knowest not?--Laugh I can never, for innocence also is sacred.

THE WATER-TEXT.

WATCHING my river marching overland,

By mighty tides, transfigured and set free,--

My river, lapped in idle-hearted mirth,

Made at a touch a glory to the earth,

And leaving, wheresoever falls his hand,

The balm and benediction of the sea,--

O soon, I know, the hour whereof we dreamed,

The saving hour miraculous, arrives!

When, ere to darkness winds our sordid course,

Some glad, new, potent, consecrating force

Shall speed us, so uplifted, so redeemed,

Along the old worn channel of our lives.

CYCLAMEN.

ON me, thro’ joy’s eclipse, and inward dark,

First fell thy beauty like a star new-lit;

To thee my carol now! albeit no lark

Hath for thy praise a throat too exquisite.

O would that song might fit

These harsh north slopes for thine inhabiting,

Or shelter lend thy loveliest laggard wing,

Thou undefiled estray of earth’s o’ervanished spring!

Here is the sunless clime, the fallen race;

Down our green dingles is no peer of thee:

Why art thou such, dear outcast, who hadst place

With shrine, and bower, and olive-silvery

Peaked islets in mid-sea?

Thou seekest thine Achaian dews in vain,

And osiered nooks jocose, at summer’s wane,

With gossip spirit-fine of chill and widening rain.

Thou wert among Thessalia’s hoofy host,

Their radiant shepherd stroked thee with a sigh;

When falchioned Perseus spied the Æthiop coast,

Unto his love’s sad feet thy cheek was nigh;

And all thy blood beat high

With woodland Rhœcus at the brink of bliss;

Thy leaf the Naiad plucked by Thyamis,

And she, the straying maid, the bride beguiled of Dis.

These, these are gone. The air is wan and cold,

The choric gladness of the woods is fled:

But thou, aye dove-like, rapt in memories old,

Inclinest to the ground thy fragile head,

In ardor and in dread.

Searcher of yesternight! how wilt thou find

In any dolven aisle or cavern blind,

In any ocean-hall, the glory left behind?

June’s butterfly, poised o’er his budded sweet,

Is scarce so quiet-winged, betimes, as thou.

Fail twilight’s thrill, and noonday’s wavy heat

To kiss the fever from thy downcast brow.

Ah, cease that vigil now!

No west nor east thine unhoused vision keeps,

Nor yet in heaven’s pale purpureal deeps

Of worlds unnavigate, the dream of childhood sleeps.

Flower of the joyous realm! thy rivers lave

Their once proud valleys with forgetful moan;

Thy kindred nod on many a trodden grave

Among marmorean altars overthrown;

For thou art left alone,

Alone and dying, duped for love’s extreme:

Hope not! thy Greece is over, as a dream;

Stay not! but follow her down Time’s star-lucent stream.
