From Chapter 7:
Hogarth himself was a confirmed pipe-lover. When he and Thornhill and their three companions set out from Gravesend for the final stage, up the river, of their famous "Five Days Peregrination," we are told that they hired a boat with clean straw, and laid in a bottle of wine, pipes, tobacco, and light, and so came merrily up the river. The arm-chair in which Hogarth was wont to sit and smoke is still preserved in his house at Chiswick, which has been bought and preserved as a memorial of the moralist-painter; and in the garden of the house may still be seen the remains of the mulberry tree under which Mr. Austin Dobson suggests that Hogarth and Fielding may have sat and smoked their pipes together in the days when George was King.

From Chapter 7:
The satirist wrote truly that after all the fashionable abstainers had been deducted, crowds remained, who smoked as heartily as their predecessors of a century earlier. The populace was still on the side of tobacco. This was well shown in 1732 when Sir Robert Walpole proposed special excise duties on tobacco, and brought a Bill into Parliament which would have given his excisemen powers of inquisition which were much resented by the people generally. The controversy produced a host of squibs and caricatures, most of which were directed against the measure. The Bill was defeated in 1733, and great and general were the rejoicings. When the news reached Derby on April 19 in that year, the dealers in tobacco caused all the bells in the Derby churches to be rung, and we may be sure that this rather unusual performance was highly popular. The withdrawal of the odious duty was further celebrated by caricatures and "poetical" chants of triumph. One of the leading opponents of the Bill had been a well-known puffing tobacconist named Bradley, who was accustomed to describe his wares as "the best in Christendom"; and when the Bill was defeated Bradley's portrait was published for popular circulation, above these lines:

Behold the man, who, when a gloomy band
Of vile excisemen threatened all the land,
Help'd to deliver from their harpy gripe
The cheerful bottle and the social pipe.
O rare Ben Bradley! may for this the bowl,
Still unexcised, rejoice thy honest soul!
May still the best in Christendom for this
Cleave to thy stopper, and compleat thy bliss!

From Chapter 5:
Among the many medicinal virtues attributed to tobacco was its supposed value as a preservative from contagion at times of plague. Hearne, the antiquary, writing early in 1721, said that he had been told that in the Great Plague of London of 1665 none of those who kept tobacconists' shops suffered from it, and this belief no doubt enhanced the medical reputation of the weed. I have also seen it stated that during the cholera epidemics of 1831, 1849, and 1866 not one London tobacconist died from that disease; but good authority for the statement seems to be lacking. Hutton, in his "History of Derby," says that when that town was visited by the plague in 1665, that at the "Headless-cross ... the market-people, having their mouths primed with tobacco as a preservative, brought their provisions.... It was observed, that this cruel affliction never attempted the premises of a tobacconist, a tanner or a shoemaker." Whatever ground there may have been for the belief in the prophylactic effect of smoking, there can be no doubt that in the seventeenth century it was firmly held. Howell in one of his "Familiar Letters" dated January 1, 1646, says that the smoke of tobacco is "one of the wholesomest sents that is against all contagious airs, for it overmasters all other smells, as King James they say found true, when being once a hunting, a showr of rain drave him into a Pigsty for shelter, wher he caus'd a pipe full to Be taken of purpose." But here Mr. Howell is certainly drawing the long-bow. One cannot imagine the author of the "Counterblaste" countenancing the use of tobacco under any circumstances.

From Chapter 10:
This experiment in the direction of wooden pipes was interesting, and deserves to be remembered; but it was not long before the briar was introduced and carried everything before it.
