Mr. James Teit informs me that a flange like the end of a spool at the mouth of the stem of a tubular pipe, makes it of a type which seems to him peculiarly characteristic of the Thompson River region. In some cases this peculiarity is carried over into the stems of pipes of the modern or elbow type, which have wooden stems, as is shown in Fig. 102. Mr. Teit has never seen or heard of tubular pipes from the Thompson River region with holes through the flanges. It seems possible that the hole in such specimens as one from Umatilla, Oregon,[329] may have been made for the attachment of ornaments or symbolic material such as feathers or for a cleaner. Ornaments were sometimes attached to pipes of the elbow type in the Thompson River region. This was done by tying in a hole bored through the hatchet-shaped piece underneath the shank close to the elbow. Pipes of the simple bowl type often had an extension at the foot of the bowl, sometimes perforated, to which ornaments could be attached. On the other hand, the hole may have been to facilitate attaching the pipe to its wooden stem. The pipes that have been perforated through the flange,[330] however, seem to have too small a bore for a wooden stem; yet, a pipe of this type with a wooden stem has been shown in Fig. 101. One reason given Mr. Teit by the Indians for the making of the flange or other thickening at the mouth of the pipe stem was to prevent the string used in attaching the pipe to the wooden stem slipping off. According to all of them, wooden stems were always used with tubular pipes as with elbow and simple bowl pipes; for a person cannot smoke any kind of stone pipe more than a few draws before it becomes too hot for the lips. To Mr. Teit's mind, no matter how small the bore of the pipe, a regular stem must have been used for smoking. [329] Smith, (h), Fig. 7a. [330] Smith, (h), Fig. 4. [Illustration: Fig. 102.
