determined by experiment, and such experiment in this case shows that the reckon- 
ing intended to be expressed is 10 chuens and a ‘‘full count’’ of days—that is, for 
practical purposes 10 chuens only, for as in the last reckoning, when the full count 
of chuens was expressed in the ahaus, so here the full count of days is expressed in 
the chuens. : 
The next glyph D1 is an ahau sign, preceded by the numeral 12. This gives us: 

Days 
12 Ahaus (12360) -...--- 4, 320 
10 Chuens (1020) ..-..-- 200 
4,520 
4, 380=12 years 

> 140 
Adding 4,520 days, or 12 years and 140 days, to the date 5 Cib 14 Kankin it 
brings us to the date 1 Cib 14 Kankin in the thirteenth year of the/annual calendar. 
Turning to the inscription we find at C2 (passing over the first half of the glyph) 
1 Cib followed by (the first half of D2) 14 Kankin, the date at which we have 
already arrived by computation. 
Passing over the next three glyphs we arrive at another reckoning. D4 gives 10 
days 11 chuens 1 ahau, and the first half of C5 gives 1 katun.

Adding 7,790 days, or 21 years and 125 days, to the previous date, 1 Cib 14 Kankin, 
it will bring us to + Cimi 14 Uo in the thirty-fifth year of the annual calendar, and 
we find this date expressed in the inscription in the glyphs D5 and C6.! 
Passing over the next three glyphs we arrive at another reckoning (E1), 3 ahaus, 
8 chuens, 15 days:

Adding 3 years and 160 days to the last date, 4 Cimi14 Uo, brings us to 11 Ymix 14 
Yax in the thirty-eighth year of the annual calendar; this is the date we find 
expressed in the glyphs E2 and F2 of the inscription. 
It is true that in the sign in the glyph E2 is not the sign usually employed for the 
day Ymix, but that it is a day sign we know from the fact that it is included ina 

1 He counts the side number of chuen symbol, chuens.
