The weary is at peace! her mortal woes

At length are ended; and she sleeps the sleep Where the long-suffering from their ills repose,

Where care finds rest and mourners cease to weep;
And shall we thoughtlessly lament the close

Of her sad pilgrimage? or vainly steep
In fruitless tears the welcome grace that Heaven
In mercy to her griefs has early given.
Oh! rather weep we o'er her agony

When for the stranger's land her parting sail
Swell'd with unwelcome winds; and her dim eye

Grew to the fading shore from which that gale Bore her for ever; then the bitterest sigh

Broke from her heart; and her pale cheek, more pale
Became, as in the wildness of despair
She thought of him who rov'd an outlaw there.
Uncertain of his fate, from day to day,

In all the tortures of suspense, how past
Her lonely hours ? how did she chide their stay,

Then, trembling, think the moments filed too fast,
Deeming in terror as they roll'd away,

Each, as it glided on, might be the last
On earth allowed him, and e'en then might gloom
O'er his dark scaffold, or his bloody tomb.
Weep for her feelings in that dreadful hour

When the dire tidings reach'd her to that strife
The pangs of death are light, and have no power :

Oh! mourn the anguish of the widowed wife,
Sinking beneath the blow, like some crushed flower,

Whose leaves the north wind withers; so her life
Faded with silent grief to slow decay,
Dissolving like pale snow in tears away.
Far from her own fair land and southern skies

The earthly relics of the wanderer rest;
Nor recks it now to her that her cold eyes

Were clos'd by strangers ; for the spirit drest
In angel splendours, freed from sorrow, flies

To seek the eternal mansions of the blest;
There in unclouded joy to meet again
Him whom on earth she lov'd and mourn'd in vain.
Reydon, near Southwold.

The Belfast News Letter published the following Porn said to be from the pen of the Author of the Ode on & John Moore :

If I had thought thou couldst have died,

I might not weep for thee;
But I forgot, when by thy side,

That thou couldst mortal be;
It never through my mind had pass'd,

That time would e'er be o'er,
When I on thee should look my last,

And thou should'st smile no more.
And still upon that face I look,

And think 'twill smile again ;
And still the thought I will not brook,

That I must look in vain ;
But when I speak thou dost not say

What thou ne'er left'st unsaid;
And now, I feel—as well I may,

Sweet Mary, thou art dead.
If thou would'st stay, ev'n as thou art,

All cold and all serene,
1 still might press thy silent heart,

And where thy smile has been ;
While ev'n thy chill bleak corse I have,

Thou seemest still mine own,
But there, I lay thee in the grave,

And now-I am alone.
I do not think, where'er thou art,

Thou hast forgotten me;
And I perhaps may soothe this heart

In thinking still of thee!
Yet there was round thee such a dawn

Of light ne'er seen before,
As Fancy never could have drawn,

And never can restore.



Fare, fare thee well, thou dying Year!

Thy parting knell is rung,
And the tear-drop glistens on thy bier,

With cypress boughs o'erhung.
Thy birth with smiles was ushered in,

And feast, and festal rout;
And merry bells, with joyous din,

From spire and tow'r rung out.
And mirth and music blest the hour,

And many a legend wild
Bade grief resign her wonted power,

While love exulting smil'd.
And meeting hands, and sparkling eyes,

Made glad thy natal day;
And withering care, and mourning sighs,

Were banished far away!
Now at thy close, how changed the scene !

The festal rout is o'er,
And the merry bells, with joyous din,

Peal forth, alas, no more!
And the lov'd and lover both are gone,

And the mourner weeps alone;
And the green grass waves o'er many a one,

That joyous, hailed thy dawn! And the hoary head by youth is laid,

And the smiling babe at rest, Sleeps the last sleep, ere woe might fade,

Or rend its sinless breast ! And blessed they thus early ta'en,

The infant cherub blest, Betime snatched from a life of pain,

And borne to endless rest!
Yet still will pitying Nature weep

Beside the daisied sod;
But blest, thrice blest are they who sleep

In the bosom of their God!
Thou dying Year! thy sunny days,

But few and brief have been;
And Memory turns her tearful gaze,

On many a fitful scene!
And blighted hopes, and broken faith,

A sad and dismal train;
All, all that fate inflicts in wrath,

Revive to wound again!
And, oh! amid remembrance drear,

Scarce blooms one little flower;--
One brightening ray the heart to cheer

In retrospection's hour!
Thou dying Year, now past away,

With time before the flood !
Thy mourning rites, and festal gay,

Thy evil, and thy good!
Thou dying year, my farewell take!

'T may be, perchance, my last; And stranger hands the lyre may wake,

That consecrates the past. And if decreed the coming year,

Death's messenger must be; I will not shed one coward tear,

To die is to be free! Liverpool.

Que te sert de chercher les tempêtes de Mars,
Pour mourir tout en vie au milieu des harsardi,

Ou la gloire te mene?
Cette mort qui promet un si digne loyer,
N'est toujours que la mort qu'avec moins de peine

L'on trouve en son foyer.
Que sert à ces héros ce pompeux appareil
Dont ils vont dans la lice eblouir le soleil

Dęs tresors du Poctole?
La gloire qui les suit après tant de travaux
Se passe en moins de temps que la poudre qui vole

Du pied de leurs chevaux. + Perhaps some of our correspondents would favour wel translation of these clever lines.

TO T. L.

FOR THE YEARS 1824 of 1825.

Farewell, farewell; to a distant land

The waves of the ocean shall bear thee, And far away to a foreign strand,

From all that's dear shall tear thee. We've tasted together the cup of joy,

And drank deep the wormwood of sorrow; And we've learnt that the world's a glittering toy,

That dazzles—to fade on the morrow. Thy course is bound to a distant cllme,

Where no loved form is near thee; Where heavily flag the moments of time,

With no voice of affection to cheer thee. When sinking beneath that sultry sun,

No such lov'd form shall caress thee;
And then should thy youtful race be run,

No parent's voice will bless thee.
Time has not furrow'd our youthful brows,

But fast the moments are fleeting:
And Age may scatter his envious snows,

Ere our hands shall join in meeting.
Tho' the voice of thy destiny calls us to part,

Nought can chill the warm tide of affection,
And till life shall depart, in the depth of my heart,

Thou shalt dwell in each fond recollection. December 16, 1824.
