From Chapter 2:
Peers and squires and parsons and peasants alike smoked. The parson of Thornton, in Buckinghamshire, was so devoted to tobacco that when his supply of the weed ran short, he is said to have cut up the bell-ropes and smoked them! This is dated about 1630. In the well-known description of the famous country squire, Mr. Hastings, who was remarkable for keeping up old customs in the early years of the seventeenth century, we read of how his hall tables were littered with hawks' hoods, bells, old hats with their crowns thrust in, full of pheasants' eggs; tables, dice, cards, and store of tobacco-pipes.

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.
