TUBULAH PIPES. 129 



that this exterior mass of asphaltum may itself have been covered with 

 mimite fragments of abalone shell, which were extensively used for deco- 

 ating- many objects in common use. 



Fig. 1, same plate, is another example of a plain pipe that has an 

 exterior coating, in places, of asphaltum, as shown in the figure. A very 

 interesting feature of this specimen is the remains of two bands of asphal- 

 tum, each nearly an inch in width, one within a short distance of the mouth 

 or larger end ; the other just above the middle of the pipe. Of itself, this 

 material could scarcely have been considered an ornament, and probably 

 was used to secure the attachment of pieces of shell or other material. 



Fig. 2, same plate, represents a very elaborately ornamented pipe. 

 Like the preceding, it has asphaltum encircling the body of the pipe near 

 the mouth or larger end, which is* further ornamented by a well-defined 

 rim, having on it a series of closely-made, incised oblique lines. The 

 asphaltum, in this instance, is in a series of narrow bead-like lines, and 

 not a nearly uniform mass, as in the preceding. Near the middle of the pipe 

 there is, in bold relief, a broad band, bounded on each side by a narrow 

 one. This central band is itself ornamented with nearly equi-distant, 

 deeply-incised cross-lines, forming diamond-shaped figures that are very 

 pleasing in effect. When we consider that this pipe was probably deco- 

 rated at the mouth of the bowl with brilliant fragments of pearly shell, and 

 that the body of the pipe is highly polished, it is seen that it was really an 

 artistic production. Of the series here described it is the most noticeable 

 specimen, except in the one feature of length and corresponding massiveness. 



Fig. 4, same plate, represents another example of an elaborately- 

 carved pipe ; but although even more has been attempted than in the pre- 

 ceding, the workmanship is inferior, and this failure to execute artistically 

 the evident design makes the specimen of far less pleasing appearance than 

 the preceding. The prominent feature of the carving consists of a series 

 of eight prominent ridges, with concave interspaces of different widths. 

 The continuity of these ridges is broken by an irregular transverse incised 

 fine that is duplicated over one-half of the series of eight ridges, as seen, 

 in part, in the illustration.
