FRAGMENTARY MASSES AND WORKED BEADS OF 

 TURQUOISE, ETC 



A number of rough masses of turquoise, sodolite, serpentine (see 

 PI. LXII), gray marble (see PI. LXIII ), agalmatolite and pagodite 

 were found, and in addition a large number of beads representing 

 each of these minerals. The majority of the turquoise beads had not 

 been worked. One, however, is an irregularly shaped mass, measur- 

 ing two and one-half inches in length by one and one-half in diameter 

 and drilled from end to end; its surface has been fairly well polished 

 (see PI. LXIV). Of lapis lazuli no less than twenty-eight carefully 

 finished cylindrical beads were found (see PI. LXV ); while of beads 

 of agalmatolite there were thirty-five (see PI. LXVI ). The majority 

 of turquoise and lapis lazuli specimens were found at the base of the 

 plateau and not in the pottery heaps of the summit of the plateau. 



MISCELLANEOUS WORKED STONES. 



Among the stones not falling within any of the categories men- 

 tioned are three worthy of brief notice. Perhaps of greatest interest 

 is a finely carved specimen representing some small quadruped ( PI. 

 LXVII, Fig, a). This is beautifully polished and has received 

 unusual attention. The specimen measures two and one-quarter 

 inches in length. Also of interest is a fragment of a stone metate (see 

 PI .LXVIII). This is five inches in width and in its original condition 

 measured perhaps a foot in length. The fragment rests on two well 

 made circular feet, one inch in length. The third specimen (see PJ. 

 LXVII, ;^) is a cone-shaped stone, being about two and one-half 

 inches in height. Just below the apex is an annular constriction, for 

 what purpose it is not known, as the groove is not of a depth to per- 

 mit of a cord having been passed around it so that it might be 

 suspended. The apex of the cone is truncated and in the center of 

 the surface thus formed is a slight depression. The under surface is 

 without marks of any sort. 



POTTERY— GENERAL CHARACTER. 



In addition to the innumerable squared stones, etc., just de- 

 scribed, the refuse heaps of the plateau yielded an immense amount 

 of pottery. Practically all of this pottery was in fragments, only two
