One of the most common of these "projects" is as follows: A young woman
goes down into the cellar, or into a dark room, with a mirror in her
hand, and looking in it, sees the face of her future husband peering at
her through the darkness,--the mirror being, for the time, as potent as
the famous Cambuscan glass of which Chaucer discourses. A neighbor of
mine, in speaking of this conjuration, adduces a case in point. One of
her schoolmates made the experiment and saw the face of a strange man in
the glass; and many years afterwards she saw the very man pass her
father's door. He proved to be an English emigrant just landed, and in
due time became her husband. Burns alludes to something like the spell
above described:--

"Wee Jenny to her grannie says,
'will ye go wi' me, grannie,
To eat an apple at the glass
I got from Uncle Johnnie?'
She fuff't her pipe wi' sic a lunt,
In wrath she was so vaporin',
She noticed na an' azle brunt
Her bran new worset apron.

"Ye little skelpan-limmer's face,
How dare ye try sic sportin',
An' seek the foul thief ony place
For him to try your fortune?
Nae doubt but ye may get a sight;
Great cause ye hae to fear it;
For mony a one has gotten a fright,
An' lived and died delecrit."
