The ICE vent is the one in activity, giving off gray vapors of strong gases, 
making we ak noises. The noise varies with the force or quantity of vapor. 
At times the noises cease and then one hears a sound like a fountain of 
water. The first vent is a little wider than 10 meters where the vapors 
escape. The depth is 10 meters, its walls are streaked as with massive 
mortar, as if caused by molten rock that was expelled like a kind of wet 
mud. It is a round, well formed vent. The second vent, to the S.W. has 
a division of a few meters. It shows no activity and is choked with sand 
that has fallen from the sides. It contains two enormous rocks at one edge 
of the bottom. The lava vents, as well as the thick lava layers at the 
hornitos, where previously the lava issued, is sunken, and the lava now con- 
tinues to surge, bu injection, with reduced activity and reissues between 
the volcano, Ganijuato and Jaratiro, almost without force, 
6 - After having acquired a simple column during the morning, at 10:30 the 
crater began to have small explosions -with puffs of cottony vapor, which at 
a low altitude drifted lazily over the east peak of the volcano. At 12 it 
is completely extinguished for 15 minutes, beginning anew with white or 
yellow cauliflowers, like cotton, and some weak noises. At 6 PM falls of 
rocks in the high mesas in the field of the hornitos. At 7:45 some 
thunderous explosions with quantities of rocks that rolled down the north 
flank of the cone. The lava again shows some illumination, surging from 
its origin in the hornitos and follows the same route as before. At 12 :30 
in the night, another explosion that makes the earth tremble and the cone 
is again covered on all its flanks with incandescent rocks, reverting then 
to nothing more than feeble noises. 
7 - The highest part of the field of the hornitos continues to grow. At the 
same time two lava flows open up and are flowing* The principal one follows
