From Chapter 4:
It is certain that the armies of the Parliament were great smokers, for the finds of seventeenth-century pipes on the sites of their camps have been numerous. A considerable number of pipes of the Caroline period, with the usual small elongated bowls, were found in 1902 at Chichester, in the course of excavating the foundations of the Old Swan Inn, East Street, for building the present branch of the London and County Bank.

From Chapter 5:
"Old English 'clays,'" says Mr. T.P. Cooper, "are exceedingly interesting, as most of them are branded with the maker's initials. Monograms and designs were stamped or moulded upon the bowls and on the stems, but more generally upon the spur or flat heel of the pipe. Many pipes display on the heels various forms of lines, hatched and milled, which were perhaps the earliest marks of identification adopted by the pipe-makers. In a careful examination of the monograms we are able to identify the makers of certain pipes found in quantities at various places, by reference to the freeman and burgess rolls and parish registers. During the latter half of the seventeenth century English pipes were presented by colonists in America to the Indians; they subsequently became valuable as objects of barter or part purchase value in exchange for land. In 1677 one hundred and twenty pipes and one hundred Jew's harps were given for a strip of country near Timber Creek, in New Jersey. William Penn, the founder of Pennsylvania, purchased a tract of land, and 300 pipes were included in the articles given in the exchange."
