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.

From Chapter 1:
Another Elizabethan who is often said to have smoked the first pipe in England is Ralph Lane, the first Governor of Virginia, who came home with Drake in 1586. Lane is said to have given Sir Walter Raleigh an Indian pipe and to have shown him how to use it. There is no original authority, however, for the statement that Lane first smoked tobacco in England, and, moreover, he was not the first English visitor to Virginia to return to this country. One Captain Philip Amadas accompanied Captain Barlow, who commanded on the occasion of Raleigh's first voyage of discovery, when the country was formally taken possession of and named Virginia in honour of Queen Elizabeth. This was early in 1584. The two captains reached England in September 1584, bringing with them the natives of whom King James I, in his "Counter-blaste to Tobacco," speaks as "some two or three Savage men," who "were brought in, together with this Savage custome," i.e. of smoking. It is extremely improbable that Captains Amadas and Barlow, when reporting to Raleigh on their expedition, did not also make him acquainted with the Indian practice of smoking. This would be two years before the return of Ralph Lane.
