When we visited the volcano it was in a state of 151 . We stood near tip of the 152 on an irregular plane. It was heaped 153 stones and cin- ders and 154 rocks which had been regularly 155 out from the volcano.
During the volcanic eruption, large quantities of rocks and stones were hurled out from the summit in terrible 156 . From the summit volumes 157 smokeand fountains of liquid fire 158 forth continuously. The smoke now white, now impenetrably black was 159 by a deep fiery roar. Stones 160 down and the molten lava moved on with a horrible sound.
