From Chapter 8:
Cowper's aversion from tobacco could not have been very strong, for he encouraged his friend to smoke in the famous Summer House at Olney, which was the poet's outdoor study. Bull smoked Orinoco tobacco, which he carried in one of the tobacco-boxes, which in those days were much more commonly used than pouches, and this box on one occasion he accidentally left behind him at Olney. Cowper returned it to him with the well-known rhymed epistle dated June 22, 1782, and beginning:

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.

From Chapter 6:
Many of the tobacco-boxes used in the latter part of the seventeenth century were imported from Holland. They were long or oval and were usually made of brass. They can be easily identified by their engraved subjects and Dutch inscriptions. An example in the Colchester Museum is made of copper and brass, with embossed designs and inscriptions, representing commerce, &c., on the base and lid. It has engraved on the sides the name and address of its owner—"Barnabas Barker, Wyvenhoe, Essex." The similar boxes later made in England usually had embossed ornamentation.

From Chapter 3:
The tobacco-tongs were more properly called ember-or brand-tongs. They sometimes had a tobacco-stopper riveted in near the axis of the tongs, and thus could be easily distinguished from other kinds of tongs. An example in the Guildhall Museum, made of brass, and probably of late seventeenth-century date, has the end of one of the handles formed into a stopper. In the same collection there are several pairs of ember-tongs with handles or jaws decorated. In one or two a handle terminates in a hook, by which they could be hung up when not required for use. In that delightful book of pictures and gossip concerning old household and farming gear, and old-fashioned domestic plenishings of many kinds, called "Old West Surrey," Miss Jekyll figures two pairs of old ember-or brand-tongs. One of these quite deserves the praise which she bestows upon it. "Its lines," says Miss Jekyll, "fill one with the satisfaction caused by a thing that is exactly right, and with admiration for the art and skill of a true artist." These homely tongs are fashioned with a fine eye for symmetry, and, indeed, for beauty of design and perfect fitness for the intended purpose. The ends which were to pick up the coal are shaped like two little hands, while "the edges have slight mouldings and even a low bead enrichment. The circular flat on the side away from the projecting stopper has two tiny engraved pictures; on one side of the joint a bottle and tall wine-glass, on the other a pair of long clay pipes crossed, and a bowl of tobacco shown in section." This beautiful little implement bears the engraved name of its Surrey maker, and the date 1795.

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.
