To record the ends of the longer time-periods in Maya notation as in 
our own, the lower periods must be represented as at o. Thus, for example, 
to record the ends of tuns, 7. ¢., the 360-day periods, both the uinal and kin 
coefficients must be 0. To record the ends of hotuns, 7. ¢., the 1,800-day 
periods, the uinal and kin coefficients must be 0, and the tun-coefficient 
either 0, 5, 10, or 15. Finally, to record the ends of even katuns, 7. ¢., 7,200- 
day periods, the tun, uinal, and kin coefficients all must be o. 
A study of the above list shows that the uinal and kin coefficients are 
both at o in one place only, namely, 9.13.0.0.0 8 Ahau 8 Uo, where, moreover, 
the tun coefficient is also o. ‘This is the equivalent of stating that the first 
date above records not only the end of a tun in the Long Count, but also the 
end of a hotun, and even of a katun. The Maya sought always to record 
upon their monuments, particularly of the stela type, the ends of periods 
in their chronological system, and even if there were not additional reasons 
to be presented later for accepting the first value, the one given above 
would be sufficient to warrant its acceptance here. 
But stronger proof of the accuracy of this reading is contained in the 
text itself. If the Initial Series of Altar I’ is 9.13.0.0.0, it becomes possible 
to connect this altar with its sister monument, Altar H’, by the distance 
number in a, ?.14.11 and at the same time it develops a plausible explanation 
for the record of its Initial Series introducing glyph in the second glyph- 
block instead of in the first. 
The Initial Series of Altar H’ is 9.12.8.3.9. Let us next count forward 
from this date, the Secondary Series number in the first glyph-block on Altar 
I’, using all the five values of the tun-coefficient there possible, 7. ¢., 11 to 15 
inclusive:
