From Chapter 2:
smoking was not confined to the auditors on the stage, who paid sixpence each for a stool. There was the "lords' room" over the stage, which seems to have corresponded with the modern stage boxes, the price of admission to which appears to have been a shilling, where the pipe was also in full blast. Dekker tells how a gallant at a new play would take a place in the "twelve penny room, next the stage, because the lords and you may seem to be hail fellow, well met"; and Jonson, in "Every Man out of his Humour," 1600, speaks of one who pretended familiarity with courtiers, that he talked of them as if he had "taken tobacco with them over the stage, in the lords' room."

From Chapter 6:
The clay pipes called "aldermen," with longer stems than their predecessors, tipped with glaze, came into use towards the end of the seventeenth century. They must not be confused with the much longer "churchwarden" or "yard of clay" which was not in vogue till the early years of the nineteenth century.
