The noises in the crater continue; at moments they are stronger than the 
escape of steam from a boiler. In the afternoon a sunset of small, yellow 
nillars of vapor. At night one can notice a dimunition of the lava flow 
near its source but between the volcano and Canijuato the front is widening. 
Very early at dawn, Sr. Segerstrom frequently not hearing the noise of the 
crater, arose and found that a new lava vent had opened up, nearer the place 
of the hornitos and in order to see better took his instrument (alidade) 
and could see the stones being, hurled from the vent. The noises in the 
crater continue like heavy deep thunder, with simple vapors that throw the 
scoria toward the southwest. 
The noises continue as heavy thunder, sometimes very deep. In the beginning 
of the volcano, there appeared a crevice running N.E.-S.7. The conduct of 
the various vents lead us to the idea that this unstable line continues. 
Similarly, in the crater, some vents follow this same line. Tor this same 
reason, it is not strange the vents continue to open, in spite of the rising 
and growing of the lava fields about the hornitos. (Apparently at this time 
a new lava vent is forming but the notes are very ambiguous here. Ed.) 
" 24 The noises continue in the crater, with some vapors that almost form yellowish 
volutes. The volutes are formed when the noise is heavy. From 10 to 
11 o'clock, rather strong noises with a quantity of bombs that fall on the 
south and southwest flank of the cone. All the volutes of vapor pass toward 
the northwest. In the afternoon the bursts of vapor accompanied by heavy 
noise, leap rapidly up. llore strong and continuous noise at 6 P. M. , as 
well as in the night and some discharge of scoria. 
" 25 Small, ivool-like clouds over all the region but these do not belong to the 
crater but form in all directions. Since yesterday the crater has been dis- 
charging vapor in volutes and may contribute to these little clouds.
