[An egg.]
In marble walls as white as milk, Lined with a skin as soft as silk; Within a fountain crystal clear, A golden apple doth appear. No doors there are to this strong-hold. Yet things break in and steal the gold.
[A horse-shoer.]
What shoe-maker makes shoes without leather, With all the four elements put together? Fire and water, earth and air; Ev'ry customer has two pair.
