From Chapter 1:
Who first smoked a pipe of tobacco in England? The honour is divided among several claimants. It has often been stated that Captain William Middleton or Myddelton (son of Richard Middleton, Governor of Denbigh Castle), a Captain Price and a Captain Koet were the first who smoked publicly in London, and that folk flocked from all parts to see them; and it is usually added that pipes were not then invented, so they smoked the twisted leaf, or cigars. This account first appeared in one of the volumes of Pennant's "Tour in Wales." But the late Professor Arber long ago pointed out that the remark as to the mode of smoking by cigars and not by pipes was simply Pennant's speculation. The authority for the rest of the story is a paper in the Sebright MSS., which, in an account of William Middleton, has the remark: "It is sayed, that he, with Captain Thomas Price of Plâsyollin and one Captain Koet, were the first who smoked, or (as they called it) drank tobacco publickly in London; and that the Londoners flocked from all parts to see them." No date is named, and no further particulars are available.

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.
