54 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 82 



Chipped implements. — A representative collection is shown in 

 figure 13, a to m. Specimens a and b are chert knives which have been 

 struck from a core much in the same manner as were the famous 

 Aztec knives of obsidian. The triangular tool c is also of chert, 

 2^ inches long, and was probably used as a knife or scraper. Objects 

 d, f, and g are drills, the first one being of especial interest because of 

 the bevelling on opposite sides of the point (see cross section e). The 

 entering edge was thus made sharper than it would have been other- 

 wise. Arrow points are of two types, plain (fig. 13, h, i, j) and tanged 

 {k, I, m). The plain points usually have slight concave bases and are 

 either short or long and slender, the latter being like the points com- 

 monly found in the Middle Gila. The bases of the tanged points are 

 flat or nearly so. 



Stone pipe.' — The pipe represented in figure 13, n and 0, is made of 

 a very even-grained slatelike rock. It is i^^ inches long and i inch 

 in maximum diameter. All outer surfaces are highly polished. The 

 bowl is formed by a conical drilling | inch in diameter at the top 

 which converges into a f -inch boring at about the middle. The boring 

 then extends from the juncture with the bowl proper to the base of 

 the object. Just above the base on the outside a large chip was knocked 

 ofif sometime during its use, for the broken surface shows much wear. 

 A small hole perforates the side wall at this point which looks as 

 though it had been made intentionally because of the small cup-shaped 

 depression about the hole. As to its significance we cannot be sure. 

 The small depression may have received the end of a stem fastened 

 into place by means of pitch or some other substance. True elbow 

 pipes, however, are the exception from southwestern ruins so that the 

 trait in question may have served another purpose or the object may 

 even have been discarded after the break occurred and put to some 

 secondary use. 



Pendant. — Figure 13, p, illustrates a plummet-shaped pendant re- 

 covered in room 2, test i. It is 2f inches long, made of slate, and 

 perforated at one end for suspension. A single notch on each side of 

 the perforation represents the only efiforts at incised decoration. 



Ring. — The small fragmentary stone ring shown in figure 13, q, 

 was probably intended to be worn by a child. The material appears 

 to be the same as that of the pipe figured here. The protuberance 

 suggests a copy of shell rings made of the Glycymeris, from which 

 the beak is usually not removed. 



Miscellaneous objects. — Crystals of quartz (fig. 13, r) are not 

 uncommon in the ruins of central and southern Arizona. One was
