Jan. 10 Only occasionally do the noises increase. Until midday there are 
winds, it was a very beautiful morning, no clouds, no dust, only a very 
clear sun with some warmth. The winds began at one o* clock, increasing 
until at two the dust clouds obscured the sun, and at six it is calm 
again. The vapor emitted by the crater forms dense clouds toward the 
Jr 
northeast and disappear at 6:45 PM., leaving the crater with only noises, 
almost without vapor. At 11 P. M. , a stream of lava flowed from a spot 
at the hornitos a little to the south of the highest mesa, with a beating 
noise. Some bombs from this vent were thrown to a height of 10 meters. 
11 — All the activity at the lava vent, that began last night, ceased 
by dawn. Only the cascade that flows along the west base of the cone 
continues 
The front of this flow, 4 kilometers from the volcano, con' 
tinues to advance at a rate of 5 meters per hour. During the morning the 
winds continue blowing to the west, later changing to the east. Although 
one notes no vapors from the crater, yet some heavy clouds form at an alti- 
tude of 2000 meters and it looks like it wants to rain toward the north of 
the volcano. The crater noises have not ceased. 
12 — There are heavy clouds at dawn, as if it wants to rain. Only momen- 
tarlljr the dusty winds from the east uncover the sun. In the crater the 
low noises continue, although they momentarily increase to a thunder. 
It is cold, particularly when the column from the crater is dense and one 
feels it more when the cloud difcM drifts to the north. 3r. Krauskopf and 
his wife, and Mrs. Segerstrom accompanied the president of the scientific 
commission studying the volcano, Sr. T,n uller , to the crater, but Sr. Puller 
did not encounter good weather. There was storm thunder at six in the 
afternoon and soon after it began to rain. The rain continued in the 
evening until midnight.
