Dec. 25 The noises fron the crater do not cease. The vapor column is now toward 
the west, with low and very simple vapors. The winds that blow from the 
west, are strongest from 12 on. The clouds that appear on distinct sides 
of the region travel toxvard the east where they form heavy black clouds. 
At 4 P. M. the vapor column begins to drift toward the southwest. The lava 
continues liquid and incandescent at its vent and lights the column to a 
great height. One can clearly distinguish tie flows between Jaratiro and 
Caniiuato. In the crater hardly an incandescent stone. 
26 At dawn the column returns to the northeast. It is a white vapor that rises 
to about 2000 meters and then stretches as a white curtain to the northeast. 
The winds continue to blow raising dust to the east. The lava continues 
flowing in Gihuatzeo at a rate of 5 meters per hour. Dense clouds form on 
the east side of the volcano. 
27 The noises do not cease, but are shorter, like thunder. At the same time 
the columns show the effect of this change, yielding vapor in puffs, which 
change into clouds, first white, then denser and darker, drifting toward the 
northeast. There are other distinct clouds that appear like white wool, 
stretching from the Cerro de Tancitaro to a large part of the region east 
of the volcano. At night bombs are thrown from the crater xvith each puff 
of vapor. 
28 There are some noises so strong they sound like thunder, accompanied by white 
cottony vapor that drifts toward the south. At 12 P. ¥ . there are some 
thunderous noises in quick succession. Incandescent bombs in the night, 
with the column directed toward the southwest. 
29 There are other noises that can be weakly heard but they are as if very deep 
in the center of the earth. They are like long thunder and shake the region, 
particularly if they come in quick succession. Today, the column of white.
