This is one called "The Leprechaun" though it may not be the one your after.

THE LEPRECHAUN
(Patrick Weston Joyce)

In a shady nook, one moonlight night
A leprechaun I spied
With scarlet cap and coat of green
A cruiskeen by his side
'Twas tick-tack-tick his hammer went
Upon the weeny shoes
And I laughed to think of a purse of gold
But the fairy was laughing too!

With tiptoe step and beating heart
Quietly, softly I drew nigh
There was mischief in his merry face
A twinkle in his eye
He hammered and song with tiny voice
And drank his mountain dew
And I laughed to think he was caught at last
But the fairy was laughing too!

As quick as thought I seiz'd the elf
"Your fairy purse" I cried
"The purse" said he "'tis in her hand-
That lady by your side!"
I turned to look - the elf was off!
Then, what was I to do?
Oh, I laughed to think what a fool I'd been
And the fairy was laughing too!
