From The Loves Of The Triangles

"Last MICHELL'S hands with touch of potent charm
The polish'd rods with powers magnetic arm;
With points directed to the polar stars
In one long line extend the temper'd bars;
Then thrice and thrice with steady eye he guides,
And o'er the adhesive train the magnet slides;
The obedient Steel with living instinct moves,
And veers for ever to the pole it loves.
