_Observations_.--The notes or remarks _utz_, _yutz kin_, a lucky day, _lob_, _u lob kin_, an unlucky day, signify that the Indians had their days of good and of ill fortune, like some of the nations of ancient Europe; although it is easily perceived that the number of their days of ill fortune is excessive, still they are the same found by me in three ancient almanacs which I have examined, and found to agree very nearly. I have applied them to the number, not the name, of the day, because the announcements of rain, of planting, &c, must, in my opinion, belong to the fixed days of the month, and not to the names of particular days; as these each year are changed, and turn upon the four primaries, _Kan_, _Muluc_, _Gix_, and _Cauac_, chiefs of the year. In another place, however, I have seen it laid down as a rule that the days _Chicchan_, _Cimi_ or _Kimi_, _Oc_, _Men_, _Ahau_, and _Akbal_, are the days of rest in the month; and this appears probable, as I see no reason why there should be so great an excess of days of ill fortune. In the almanacs cited above, this order was not observed, either from ignorance or excessive superstition. Thus the days on which the burner takes his fire, kindles it, gives it free scope, and extinguishes it, are subject to the 3d, 4th, 10th, and 11th of the days _Chicchan_, _Oc_, _Men_, and _Ahau_; as they say, for example, that on the 3d Chicchan the burner takes his fire, on the 10th Chicchan he begins, the 4th Chicchan he gives it scope, and the 11th Chicchan he extinguishes it; the same may be said of Oc, Men, and Ahau; from which we see that these epochs are movable, as the days 3, 4, 10, and 11 do not always fall on the same days of the month, but only according to the combination of the weekly numbers with the days referred to. It may be asked, who is this burner that takes his fire, kindles it, permits it to destroy, and extinguishes it? To this I cannot reply, as I have been unable to find an explanation of the mystery; perhaps the days specified might be days of sacrifice, or some other act of superstition.
