Analysis of To The Reverend William Bull

My dear friend,
If reading verse be your delight,
'Tis mine as much, or more, to write;
But what we would, so weak is man,
Lies oft remote from what we can.
For instance, at this very time,
I feel a wish, by cheerful rhyme,
To soothe my friend, and had I power,
To cheat him of an anxious hour;
Not meaning (for I must confess,
It were but folly to suppress)
His pleasure or his good alone,
But squinting partly at my own.
But though the sun is flaming high
I' th' centre of yon arch, the sky,
And he had once (and who but he?)
The name for setting genius free;
Yet whether poets of past days
Yielded him undeserved praise,
And he by no uncommon lot
Was famed for virtues he had not;
Or whether, which is like enough,
His Highness may have taken huff,
So seldom sought with invocation,
Since it has been the reigning fashion
To disregard his inspiration,
I seem no brighter in my wits,
For all the radiance he emits,
Than if I saw through midnight vapor
The glimm'ring of a farthing taper.
O for a succedaneum, then,
T' accelerate a creeping pen,
Quod caput, cerebrum, et cranium
Pondere liberet exoso,
Et morbo jam caliginoso!
'Tis here; this oval box well fill'd
With best tobacco, finely mill'd,
Beats all Anticyra's pretences
To disengage the encumber'd senses.

O Nymph of Transatlantic fame,
Where'er thine haunt, whate'er thy name,
Whether reposing on the side
Of Oroonoquo's spacious tide,
Or list'ning with delight not small
To Niagara's distant fall,
'Tis thine to cherish and to feed
The pungent nose-refreshing weed,
Which, whether, pulverized it gain
A speedy passage to the brain,
Or, whether touch'd with fire, it rise
In circling eddies to the skies,
Does thought more quicken and refine
Than all the breath of the Nine--
Forgive the Bard, if Bard be he,
Who once too wantonly made free
To touch with a satiric wipe
That symbol of thy power, the pipe;
So may no blight infest thy plains,
And no unseasonable rains,
And so may smiling Peace once more
Visit America's sad shore;
And thou, secure from all alarms
Of thund'ring drums and glitt'ring arms,
Rove unconfined beneath the shade
Thy wide-expanded leaves have made;
So may thy votaries increase,
And fumigation never cease.
May Newton, with renew'd delights
Perform thine odorif'rous rites,
While clouds of incense half divine
Involve thy disappearing shrine;
And so may smoke-inhaling Bull
Be always filling, never full.
