|Henry Gellibrand geophysics|
- You see, wherever and whenever you look,
- a different magnetic declination
- since the magnetic north pole drifts
- about the northern regions of the earth
- and has never in recorded history
- coincided with the point above which
- the stars appear to revolve.
- In this world, not only in an ideal world,
- a position that cannot be easily reached
- may yet be calculated, circumscribed, realized
- by imperfect beings with crude instruments.
- Mountains rise, continents move, glaciers
- carve bays and valleys, but this position
- never varies, or varies by only a hair.
- North and south magnetic poles
- move in different directions
- at different rates,
- suggesting Earth’s magnetic field,
- the imperfect bundle of many fields,
- is fragmented, not bent.
- Don’t let them fool you,
- but whom can you believe?
- It doesn’t dip toward the ground,
- but turns to the right or to the left.
- Your brain, it turns out, is easily deceived
- when given only your point of view.
- Gullible eyes, gullible ears,
- and lazy bones often lead a ship astray.
