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 north- 
east. The dust blows from west to east. The effect of the deep thunder 
in the crater is shown in the creased volutes of black vapor accompanying 
the yellow.

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 books on volcanoes some photographs with vapors and 
clouds that formed themselves in this manner, but I did not believe i-,. 
Now I am convined because I am now seeing how tney form, - n ..i-nt, 
the crater, with reduced vapors, explodes with a regular thunder, throwing 
out bombs that fall on all slopes of the cone. They continue from

at an altitude into a simple white curtain. At 10 o'clock the crater

thin with a height up to 2,000 meters. Prom afar, one notes that some 
ascend the cone to the crater rim, others pass on the sides of the cone.
