Jan. 13 From five to six in the morning there are some very deep noises 
that resound deep in the earth, at the same time one can hear some noises 
in the crater like pistol shots, noises that follow each other in quick 
succession, each 4 or 5 seconds. The heavy clouds continue over all the 
region, almost with continuous rain and cold. It is similar to the time 
* 
previous to the volcano when the Cerro de Tancitaro carried some snow, and 
for two or three days everything in the Cerro gleamed. White vapors and 
blue fumes arise at the lava vents while in the crater are thick, loiv white 
vapors, drifting toward the northwest. 
14 - Rain in all the region all day. In some parts the rains are heavier, 
as some travelers from Los Reyes inform me. Similarly the rains at TJruapan 
are heavy and the higher hills have been receiving some snow. The noises 
today are heard as far as 35 kilometers away. 
15 - Although the region continues cloudy, the rains have ceased. The 
noises in the crater continue, somewhat louder each 8 minutes. White vapors 
are emitted by the crater without force. 
36 - Toward the east and northeast clouds continue to form, becoming darker 
and darker, until it wants to rain. In the crater are continuous hut not 
very strong noises. The lava cascade continues in activity. At 6 F. M. 
the clouds have almost disappeared. Only the vapors from the crater con- 
tinue, but at times they are interrupted; and so it will continue during 
the night. 
17 - The crater noises do not cease nor do they increase but are always 
calmly emitted, transparent like mist; hut heavy, black clouds gather toward 
the northeast, as if it wants to rain. It is rare that it has rained for 
three or four days and the mountains, particularly Tancitaro, have received 
no snow. 
Before the volcano it is certain that at this time there would
