A Humming-bird, on lightning wing,

Was hovering near a lovely bower, A glancing, rapid, humming thing,

That bore the hue of every flower. Swift to a blooming rose he flew,

To sip the dainty, scented sweetA sparkling drop of honey dew,

Dropp'd at the pistil's golden feet. Just as he sought to probe the cell,

With keen desire to find the store, A Honey Bee that knew it well,

Sung while the wealth away he bore. Thus Pleasure oft allures for naught,

And leaves the soul unsatisfied; Which, like the Humming-bird untaught,

Reproaches Fate, as when he cried

Nor murmuring tribes from me derive
Th' ambrosial amber of the hive;
Yet leave this barren spot to me:
Spare, woodman, spare the beechen tree !

Thrice twenty summers I have seen
The sky grow bright, the forest green;
And many a wintry wind have stood
In bloomless, fruitless solitude,
Since childhood in my pleasant bower
First spent its sweet and sportive hour,
Since youthful lovers in my shade
Their vows of truth and rapture made ;
And on my trunk's surviving fame
Carved many a long-forgotten name.
Oh! by the sighs of gentle sound,
First breathed upon this sacred ground;
By all that Love has whisper'd here,
Or Beauty heard with ravish'd ear;
As Love's own altar honour me:
Spare, woodman, spare the beechen tree!



“Why didst thou give thy nectar up

To that unfashion'd, droning thing? I claim alone the ruby cup,

When I come by with rainbow wing. “With soft, sweet tone and soothing strain,

I here my earthly vows renew,
And I must have them back again

In drops of amber ever new."
The blushing Rose, in conscious pride

Of innocence, and duty done,
Turn'd but a struggling bud aside

To catch the June enlivening sun : And answerd, " This may teach thee why

Thou, fair bright visitor! would'st sip The bounty of the morning sky,

And take the sweetness from my lip: " And so doth he-but wisely turns

E'en drops to luscious stores of sweet, And by his faithful labour earns

The homage I each day repeat. “ The labourer who sings and prays

In sweet Employment's busy hum, Shall worship in the sunny rays,

And find ere night the answer come. “The labourer who toils and sings,

Shall sing because his toil is love, Whose spirit hovers on the wings

Of Hope-the toiler's early dove."

“WATER! Water !” cries the bird,

With his singing, gentle note; And the liquid cry is heard

Pouring from the little throat, Water ! water ! clear and sweet!

“To-weet! To-weet!” “ Water! Water!" roars the ox,

While it rushes at his side, Down among the mossy rocks

Rippling with its crystal tide ; Water! water ! pure and true!

“Moo! Moo!” “Water! Water !" said the tree,

With its branches spreading high; . “Water ! Water !" rustled he,

For his leaves were very dry; Water! water! for the tree !

Pure and free ! “Water ! Water !” said the flower,

Whispering with its perfumed breath “Let me have it in an hour,

Ere I thirsting droop in death! Water, water, soft and still,

Is my will !” “Water! Water !” said the grain,

With its yellow head on high; And the spreading, fertile plain,

Ripening, join'd the swelling cry;
Water for the grains of gold !

Wealth untold !
Water! Water! sparkling, pure,

Giveth Nature everywhere-
If you drink it, I am sure

It will never prove a snare !
Water is the thing for me

Yes! and thee !
Water! Water! young and old !

Drink it, crystal-like and sweet!
Never heed the tempter bold-

Crush him underneath your feet! Water! Water! Youth for thee

Thee and me!


THE BEECH TREE'S PETITION. o leave this barren spot to me! Spare, woodman, spare the beechen tree! Though bush or flow'ret never grow My dark unwarming shade below; Nor summer bud perfume the dew Of rosy blush, or yellow hue ! Nor fruits of autumn, blossom-born, My green and glossy leaves adorn;
