Feb. 15 Strong winds at dawn blowing from east to west. The vapors from the 
crater, mingled with the windblown dust drag low over the fields to the 
north of the volcano. At 3 in the afternoon the winds change to the 
east. The vapor of the crater drifts to the northwest. All the 
region is filled with dust during the day. 
16 Hot only when the wind blows but also on days when there is no wind, one 
sees the region filled with dust. The yellowish vapors from the crater, 
in spite of long and deep noises, rise with little force but always with 
ash. In the afternoon the column drifts toward the northeast. The dust 
blows from west to east. The effect of the deep thunder in the crater 
is shown in the increased volutes of black vapor accompanying the yellow. 
17 At ten in the morning, as usual, the winds from the west augment more and 
more. The black volutes accompanying the yellow vapors carry very fine 
ash, which showers toward the north. The noises continue, at times rather 
strong, at times they cease, or one hears them very long and deep. 
In the afternoon the vapors drift to the northeast. I think that most of 
the clouds on the horizon are the result of the volcano. Before this 
volcano I saw in some hooks on volcanoes some photographs with vapors and 
clouds that formed themselves in this manner, but I did not believe it. 
How I am convinced because I am noxv seeing how they form. In the night,

“thB crater, with reduced vapors, explodes with a regular tminder, turovnn^ 
out bombs that fall on all slopes of the cone* They continue from 
9 o’clock on but with less force* 
18 Some white vapcrs emitted from the crater which extend themselves at an 
altitude into a simple white curtain at 10 o’clock the crater forms some 
pillars of black smoke with heavy noise. At noon a column with cauli- 
flowers. Heavy clouds have formed in the region north of the volcano. 
After 3 P. M. vapors yellow and cottony*
