From Chapter 2:
Tobacco was smoked by all classes and in almost all places. It was smoked freely in the streets. In some verses prefixed to an edition of Skelton's "Elinour Rumming" which appeared in 1624, the ghost of Skelton, who was poet-laureate to King Henry VIII, was made to say that he constantly saw smoking:

As I walked between
Westminster Hall
And the Church of Saint Paul,
And so thorow the citie,
Where I saw and did pitty
My country men's cases,
With fiery-smoke faces,
Sucking and drinking
A filthie weede stinking.

Tobacco-selling was sometimes curiously combined with other trades. A Fleet Street tobacconist of this time was also a dealer in worsted stockings. A mercer of Mansfield who died at the beginning of 1624, and who apparently carried on business also at Southwell, had a considerable stock of tobacco. In the Inventory of all his "cattalles and goods" which is dated 24 January 1624, there is included "It. in Tobacco 19.li 0. 0." Nineteen pounds' worth of tobacco, considering the then value of money, was no small stock for a mercer-tobacconist to carry.

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.
