But sweet little creatures have sometimes, they say,
A great deal that's bitter, or sour, to betray!
And often the humming-bird's delicate breast
Is found of a very high temper possessed.
Such essence of anger within it is pent,
'Twould burst did no safety-valve give it a vent.
Displeased, it will seem a bright vial of wrath,
Uncorked by its heat, the offender to scath;
And, taking occasion to let off its ire,
'Tis startling to witness how high it will fire.
