The deepest noises sound like the howling of beasts.

" 16 The noises and the vapors lessen; the latter from only thin intermittent 
columns that are interrupted each few minutes. At 9 in the morning the 
vertical coluxan remained fixed, rising to a height of 300 meters, later 
drifting to the north. 
The lava has continued its advance toward the northwest, covering the sites 
of the last remaining houses of the village of Paricutin. In the night, 
there are no incandescent bombs from the crater. 
” 17 Strong noises and a very white vapor, with some ash, issue from the crater. 
In the area to the south there are no lava vents now, only some rock falls. 
There is a very active one, however, in a small cone traversed by a fissure 
some 200 meters long, which begins some 60 meters southwest of the cone. 
It begins in front of a small mesa, making a cascade Town the slope. At its 
origin it has a width of 3/4ths meter, that in a distance of 10 meters widens 
to a flow of 15 or 20, becoming wider and wider* The velocity in the cascade 
is about 60 meters per minute. This flows a course different from the other 
flows. There is another that flows nearer the base of the cone. All these 
flow- toward the north, passing the site of the village of Paricutin. 
In the afternoon a white column of vapor inclined toward the east, in which 
direction it rained. At night, incandescent bombs, without cease. 
Tf 18 The noises diminish somewhat. The vapor column always white and thin, di- 
rected toward the northeast, to a distance of several kilometers. This vapor 
is changed into a thin white mist. In the night little incandescent scoria 
from the crater.
