Analysis of Montague Leverson

As some enormous violet that towers
Colossal o'er the heads of lowlier flowers
Its giant petals royally displayed,
And casting half the landscape into shade;
Delivering its odors, like the blows
Of some strong slugger, at the public nose;
Pride of two Nations-for a single State
Would scarce suffice to sprout a plant so great;
So Leverson's humility, outgrown
The meaner virtues that he deigns to own,
To the high skies its great corolla rears,
O'ertopping all he has except his ears.
