From Chapter 1:
King James, in his reference to the "first Author" of what he calls "this abuse," clearly had Sir Walter Raleigh in view, and it is Raleigh with whom in the popular mind the first pipe of tobacco smoked in England is usually associated. The tradition is crystallized in the story of the schoolboy who, being asked "What do you know about Sir Walter Raleigh?" replied: "Sir Walter Raleigh introduced tobacco into England, and when smoking it in this country said to his servant, 'Master Ridley, we are to-day lighting a candle in England which by God's blessing will never be put out'"!

From Chapter Chapter 8:
He describes the box and its contents in lines which show not only tolerance but appreciation of tobacco, from which it is not unreasonable to infer that Cowper's first view of his friend's smoking-habit as a drawback—as shown in his letter to Unwin, quoted above—had been modified by neighbourhood and custom. It might have been well for the poet himself if he had learned to smoke a social pipe with his friend Bull. The appreciative lines run thus:

This oval box well filled
With best tobacco, finely milled,
Beats all Anticyra's pretences
To disengage the encumbered senses.
O Nymph of transatlantic fame,
Where'er thine haunt, whate'er thy name,
Whether reposing on the side
Of Oronoco's spacious tide,
Or listening 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, touched with fire, it rise
In circling eddies to the skies,
Does thought more quicken and refine
Than all the breath of all the Nine—
Forgive the bard, if bard he be,
Who once too wantonly made free,
To touch with a satiric wipe
That symbol of thy power, the pipe;
        *     *     *     *     *     *     *
And so may smoke-inhaling Bull
Be always filling, never full.
