(Fig. 49) and the six 

 raised rectangles in the 

 corners of the second 

 ts'ung (Fig. 50) are re- 

 garded as "teeth" and 

 compared with the 

 teeth of a saw. We said 

 before that they are 

 called by a special des- 

 ignation tsu, a charac- 

 ter composed of the 

 radical horse and a pho- 

 netic complement tsie; 

 but Cheng K'ang- 

 ch'eng explains that it 

 must be read tsu writ- 

 ten with radical 120 for 

 silk (Giles No. 11828), 

 and this word tsu de- 

 notes a silk band or 

 cord, and because these ob- 

 jects were wrapped up with 

 bands, that name was ap- 

 plied to them. Wu Ta- 

 ch'eng says, and this seems 

 quite plausible, that the 

 bands were tied around the 

 deep-lying portions between 

 the projecting rectangles, so 

 that it would follow that the 

 word tsu refers to the spaces 

 between these, and not to 

 the rectangles themselves. 

 Judging from the character 

 of these specimens and the 

 traditions regarding the jade 

 type ts'ung, there is no doubt 

 of their identification. Wu 

 Ta-ch'eng furnishes us also 

 a clue as to their name 

 "chariot wheel-nave," by 

 making the following intro-
