For who did ever the Earths Centre pierce,
And felt or sand or gravell with his spade
At such a depth? what Histories rehearse
That ever wight did dare for to invade
Her bowels but one mile in dampish shade?
Yet I’ll be bold to say that few or none
But deem this globe even to the bottome made
Of solid earth, and that her nature’s one
Throughout, though plain experience hath it never shown.
