From Chapter 2:
When Robert, Earl of Essex, and Henry, Earl of Southampton, were tried for high treason in Westminster Hall on February 19, 1600-1, the members of the House of Lords, who with the Judges formed the Court, if we may believe the French Ambassador of the time, behaved in a remarkable and unseemly manner. In a letter to Monsieur de Rohan, the Ambassador declared that while the Earls and the Counsel were pleading, their lordships guzzled and smoked; and that when they gave their votes condemning the two Earls, they were stupid with eating and "yvres de tabac"—drunk with smoking. This was probably quite untrue as a representation of what actually took place; but it would hardly have been written had smoking not been a common practice among noble lords.

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.
