Loch-a-bo. How sweet a little spot is here !

O, from loath'd scenes of selfish strise, Who'd think, 'ınid shapeless hills so drear, Where dulness chills the springs of life, To meet with such a scene ?

How gladly I'd retreat
It seems some fairy solitude,

To this embow'ring solitude,
Where elves resort in lightsome mood, Where no vain cares or wrongs obtrude
To sport 'mong copses green.

The tranquil mind to fret!
How calm the little lake doth lie, All day, among the willows green,
Reflecting the soft Summer sky,

I'd muse upon the varied scene
One sheet of azure hue !

In soothing reverie ;
And, raising their round heads, are seen The deer would pass me tamely by ;
The wooded isles of softest green,

The wild drake on his webb’d oars lie,
Ainid the waters blue.

Not timorous of me.
Dark woods hemm'd round on every side, And when at eve far to the woods,
And tow'ring hills extended wide, The heron, angler of the foods,
Shut out the world unknown;

Slow soaring took his fight;
No human footstep presses here ;

I'd cross the blue lake in my skiff, The wild fowl and the dappled deer To the lone cot beside the cliff, Make the lone spot their own.

And dream of bliss all night! C.
