EVOLUTIONARY CHANGES IN THE CLAY TOBACCO-PIPE 15 CHAPTER THREE Evolutionary changes in the clay tobacco-pipe EVOLUTION OF STEM-LENGTH AND SHAPE AFTER the first few years of very small pipes with 3" or 4" stems, the ordinary stem-length seems to have been standardised at about 8" to 9", with increasing bowl-size, for nearly the whole of the seventeenth century, although some straight stems of 12" to 14" appeared after the Restoration. The "Alderman", with a straight 12" stem tipped with glaze came to popularity at the extreme end of the seventeenth century, and in the early years of the eighteenth century, stem-lengths of 16" to 18" were usual. The enormous "Churchwarden" with stem two or even up to three feet long, appeared in 1819 and survived until the end of the nineteenth century, in competition with the "cutty" of 7" stem, which eventually replaced it. The "Churchwarden" is characteristic of nineteenth century fireside smoking, its long curved stem enabling the smoker to rest his elbow while still holding the bowl, while the "cutty" suggests the pocket-pipe of the open-air man, gamekeeper, labourer, sailor. In the North of England particularly, the common name for a clay pipe throughout the eighteenth and nineteenth centuries was a "broseley", for obvious reasons connected with the main centre of its manufacture, but the Churchwarden soon got the name "yard of clay". EVOLUTION OF BOWL FORM Although everywhere the general trend was from the smaller to the larger bowl, in more detailed points of design it is by no means true that the various centres of manufacture followed the same sequence simultaneously. Throughout these notes, the 'norm' has been taken to be the pattern prevailing at the time in the North Midlands, the principal pipe-producing area of England. London pipes follow the Midlands sufficiently closely for all but specialist treatment to enable them to be classed together in development of stem and bowl. An important exception from the Midlands is the product of Broseley in Shropshire; the most notable distinguishing features of many Broseley pipes being the heavy, so-called "heart-shaped" foot (which is more often battledore-shaped in section), and the
