From Chapter 3:
It would seem, from one example I have noted, as if in some places smoking were not allowed in public-houses. In the account-book of St. Stephen's Church and Parish, Norwich, the income for the year 1628-29 included on one occasion 20s. received by way of fine from one Edmond Nockals for selling a pot of beer "wanting in measure, contrary to the law," and another sovereign from William Howlyns for a like offence. This is right and intelligible enough; but on another occasion in the same year each of these men, who presumably were ale-house keepers, had to pay 30s.—a substantial sum considering the then value of money—for the same offence and "for suffering parishioners to smoke in his house." I have been unable to obtain any information as to why a publican should have been fined an additional 10s. for the heinous offence of allowing a brother parishioner to smoke in his house.

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.
