Jan. 10 Only occasionally do the noises increase. Until midday there were 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 later until 
at two the dust clouds obscured the sun, and at six it was calm again. 
The vapor emitted by the crater formed dense clouds toward the northeast 
and disappeared at 6:45 F. II., 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 continues 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 altitude of 2000 
meters and it looks like it wants to rain to'.vard 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 momentarily 
the dusty winds from the east uncover the sun. In the crater the sort 
noises continue, although they momentarily increase to a thunder. It is 
cold, particularly when the column from the crater is dense and one feels 
Konrad 
it more when the cloud drifts to the north. Sr • /i\rauskopl snd his wixe, 
Kenneth 
and Mrs . /Segerstrora accompanied the president of the scientific commission 
Richard 
studying- the volcano, Sr. -Fuller to the crater, but Sr. Richard Puller did 
not encounter good weather. There was storm thunder st six in the after- 
noon and soon after it began to rain. The rain continued in the evening 
until midnight.
