The fire seven times tried this: / Seven times tried that judgement is, / That did never choose amiss. / Some there be that shadows kiss: / Such have but a shadow's bliss. / There be fools alive, I wis, / Silver'd o'er; and so was this. / I will ever be your head: / So be gone: you are sped.

If the Coward Bumble Bee / In his chimney corner stay, / I, must resoluter be!
