EVOLUTIONARY CHANGES IN THE CLAY TOBACCO-PIPE 17 It seems likely that these simple marks on the flat base of the foot of an early pipe indicate that it was made at a pottery already long-established, but simple marks occur on much later pipes and by themselves, are no indicators of antiquity. When special clay-pipe factories started to turn out thousands of pipes in the first quarter of the seventeenth century, it became usual to mark the underside of the bowl or foot with initials, often of the maker, more rarely of the publican or tobacconist who sold, or gave the pipes to his customers. Up to about 1640, these initials also were incuse, like the marks which preceded, or sometimes accompanied them; thereafter, more often they were moulded in relief or embossed, although the incuse form continued in the West Country to the end of the seventeenth century. The relief form seems to have originated in London about 163016, and diffused from that centre with the usual delay of a decade or so. After the Restoration in 1660, it became the fashion to mark the sides of the foot or spur with initials, instead of the base, and this custom persisted well into the eighteenth century. For precise definition of the terms used in describing parts of a clay-pipe, see fig. 5, page 22. INITIALS ON PIPES AND HOW TO READ THEM It has been discovered that when two initials are present, one on each side of the foot or bowl, if the pipe be held with the bowl away from the reader (as if he were smoking it), the initial on the reader's RIGHT represents the surname, that on the LEFT, the Christian name. This convention appears to have been com- monly followed, astonishing though it be that such a standardisa- tion should have been achieved throughout the country. The custom of initialling pipes as a mark of manufacture, died out in the eighteenth century, after over a hundred years of use; its re- appearance in the nineteenth century is in the nature of a conscious revival, and was never general. OTHER DEVICES AND MARKS On some other early pipes, the maker's name is concealed in the form of a 'rebus', the name of the thing pictured being also the maker's name, or sounding like it. Such a rebus is moulded on the front of the bowl and sometimes on the flat base of the foot as well. An example of this is the GAUNTLETT pipe, many thousands of which must have been made in the seventeenth and eighteenth centuries by the pipe-making family of Gauntlett. The trademark on the bowl was a shield bearing a gauntlet (thumb extended to the right) and below the shield, in one large example with a 4" bowl, the initials G B and date 1698. On the base of the foot of this particular pipe is a circle of dots enclosing a miniature of the shield and gauntlet, of course without date or initials7. It is interesting to observe that the surname initial is to the left, when facing the reader, but also follows the convention detailed above.
