] THE PROOF OF THE INTERCALATION. 47 



3. As shown by this list, the years follow each other iu the order 

 heretofore given, that is to say, 9 Lamat, 10 Ben, 11 Ezanab, 12 Akbal, 

 13 Lamat, 1 Ben, 2 Ezanab, 3 Akbal, and 4 Laiuat, the upper line of 

 days ending with 9 Ahan, the thirteenth day of the thirteenth month, 

 Mac, of the last named year. 



The entire series, commencing with 2 Ymix, the thirteenth day of 

 Mac, in the year 9 Lamat, and ending with 9 Ahau, the twelfth day of 

 Mac, in the year 4 Lamat, consists of 2,920 days, or precisely eight 

 years of 365 days each.* 



Having reached the end of the series consisting only of the top days 

 of the columns, the question arises, Does the series continue to the 

 second line of days, and so on to the end of the bottom, or thirteenth 

 horizontal line? If so, counting 11 months and 10 days from 9 Ahau, 

 over the last column of plate 50, should reach 11 Gib, the fourth day 

 of Yaxkin, which is the second day of the first column of plate 46, and 

 the beginning of the second horizontal line of days. This line, as 

 will be seen by turning to the series of columns heretofore given in 

 table 1 (page 18), is as follows: 



Plate 46-11 Gib. 10 Gimi. 



47-10 Ahau. 9 Oc. 



48- 9 Kan. 8 Ix. 



49- 8 Lamat. 7 Ezanab. 



50- 7 Eb. 6 Ik. 

 The lines follow each other in a single continuous series. Turning 



now to 9 Ahau (in table 6, page 39) the thirteenth day of Mac, in the 

 year 4 Lamat, the day with which the first line ended, and counting 

 from this 11 months and 16 days, including the five supplemental days 

 at the end of the year, 11 Gib, the fourth day of Yaxkin in the year 

 of 5 Ben is reached. This is the second day of the first column on plate 

 40. A count of 4 months and 10 days more reaches 10 Gimi, the four- 

 teenth day of the month Zac, which is the second day of the second 

 column of plate 46. And so the count may be continued to 1 Ahau, the 

 last day of the fourth column on plate 50, and the last of the complete 

 series of thirteen lines, covering in all a period of 104 years, or two 

 cycles. But to complete this series only the upper line of months on 

 table 2 has been used. This series, as above sta'ted, ends with 1 

 Ahau, the thirteenth day of Mac, the thirteenth month of the year 

 9 Lamat, but a year of a different cycle from that in Avhich the 

 count began. If the count is carried 11 months and 16 days from this 

 (late it will reach 3 Gib, the fourth day of Yaxkin in the year 10 Ben, 

 precisely the year in which the first 3 Gib is found. This shows that 

 the series is complete, as it returns to the starting point. 



* It will be seen by reference to my paper entitled "Aids to the study of the Maya 

 codices," 6th Ann. Rep. Bnr. Ethn., p. 302, that the conclusiou there reached is 

 shown by the discovery here exphiiued to be incorrect. I had not found at that 

 time satisfactory evidence of tlie introduction of the five supplemental days or of 

 the four series of years.
