7 ’rom five to six in the morning are some very deep noises that resound 
deep in the earth, at the same time one can hear some noises in the crater 
lixe 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 carries some snow and for two or three 
days everything in the Cerro gleamed. At the lava vents arise white vapors 
and blue fumes, while in the crater are thick, low white vapors, drifting 
toward the northwest. 
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 Uruapan 
% 
are heavy and the higher hills have been receiving some snow* The noises 
today are heard as far as 35 kilometers away. 
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. 
Toward the east and northeast clouds continue to form, becoming darker and 
not 
darker, until it wants to rain* In the crater are continuous but/very 
strong noises. The lava cascade continues in activity. At 6 P. M. the 
clouds have almost disappeared* Only the vapors from the crater continue, 
but at times they are cut off, and so it will go during the night. 
The crater noises do not cease nor do they increase but are always calmly 
emitted, transparent like mist; but heavy, black clouds gather toward the 
northeast, as if it wanted 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 
have been snow. The new lava that flows toward the northwest now has
