From Chapter 3:
Taking tobacco was clearly an accomplishment to be studied seriously. Shift, a professor of the art in Jonson's play, puts up a bill in St. Paul's—the recognized centre for advertisements and commercial business of every kind—in which he offers to teach any young gentleman newly come into his inheritance, who wishes to be as exactly qualified as the best of the ordinary-hunting gallants are—"to entertain the most gentlemanlike use of tobacco; as first, to give it the most exquisite perfume; then to know all the delicate sweet forms for the assumption of it; as also the rare corollary and practice of the Cuban ebolition, euripus and whiff, which he shall receive, or take in here at London, and evaporate at Uxbridge, or farther, if it please him."

From Chapter 7:
The country gentlemen of the time followed the hounds and enjoyed rural sports of all kinds, drank ale, and smoked tobacco. They had their smoking-rooms too. Walter Gale, schoolmaster at Mayfield, Sussex, noted in his Journal under date March 26, 1751: "I went to Mr. Baker's for the list of scholars, and found him alone in the smoaking-room; he ordered a pint of mild beer for me, an extraordinary thing." Gale himself was a regular smoker, and too fond of pints of ale.

Fielding has immortalized the squire of the mid-eighteenth century in his picture of that sporting, roaring, swearing, drinking, smoking, affectionate, irascible, blundering, altogether extraordinary owner of broad acres, Squire Western. We may shrewdly suspect that the portrait of Western is somewhat over-coloured, and cannot fairly be taken as typical; but there is sufficient evidence to show that in some respects at least—in his enthusiasm for sport and love of ale and tobacco—Western is representative of the country squires of his day.
